Real-time Machine Learning: Motivations and Challenges
This talk covers the two levels of real-time machine learning: online prediction (as opposed to batch prediction) and continual learning (as opposed to batch learning). Online prediction means making predictions as soon as requests arrive. Continual learning is when an ML system allows an ML system to automatically update with new data in production, speeding up the iteration cycle to combat model performance’s decay due to concept drift.
Real-time machine learning allows a system to be adaptive to changing users' behaviors and environments, which leads to better model performance and, in some cases, reduced compute cost. However, real-time ML comes with many infrastructural and theoretical challenges, and this talk discusses the key challenges.

Quantization at Hailo – Co-Evolution of Hardware, Software and Algorithms
“Power-efficient hardware for deep neural network (DNN) acceleration is a major obstacle for the successful deployment at scale of many edge AI applications such as autonomous driving, smart retail, smart cities and more. Quantization is exploited by modern DNN acceleration at the edge to significantly reduce power consumption. In the first part of the talk, we will give a brief overview of the hardware aspects of quantization, followed by a high-level review of the main approaches to quantization. We show how these concepts are leveraged in the Hailo-8, a highly power-efficient DNN accelerator. In the second part, we discuss "real-world" challenges of quantization as well as suggest perspectives for future work to address current gaps.”
Towards fully unsupervised learning
Supervising with boolean class labels all future scenarios a machine learning application may encounter is understood to be infeasible, leading to renewed interest in adaptive and self-supervised methods. Yet several popular “unsupervised” methods implicitly presume knowledge of target domain invariances. I’ll present new methods that do not require hand-selecting augmentation strategies and learn without supervision: multi-task contrastive learning, automatic selection of augmentation policies, and entropy-based adaptation at test time without access to source labels or data. Fully unsupervised and adaptive learning can work together to dramatically reduce the level of supervision required for real-world tasks.

Embedding Synthetic Assets Using a Neural Radiance Field
At Datagen, we maintain a large catalogue of artist-made 3D assets from many categories (i.e. tables, chairs,bottles, etc.). Each asset consists of a 3D mesh and a texture map. We form an alternative, implicit volumetric representation of all assets, where each asset in a category is assigned a latent code. A single network coupled with a differential renderer is trained to render 2D images of each asset given its code, that are similar to the images rendered directly from the asset's mesh. The codes fully encapsulate the assets shape and appearance, and can be used to extract the visual attributes of each asset, without the need to re-render it.

Local Trajectory Planning For UAV Autonomous Landing
An important capability of autonomous Unmanned Aerial Vehicles (UAVs) is autonomous landing while avoiding collision with obstacles in the process. Such capability requires real-time local trajectory planning. Although trajectory-planning methods have been introduced for cases such as emergency landing, they have not been evaluated in real-life scenarios where only the surface of obstacles can be sensed and detected. We propose a novel optimization framework using a pre-planned global path and a priority map of the landing area. Several trajectory planning algorithms were implemented and evaluated in a simulator that includes a 3D urban environment, LiDAR-based obstacle-surface sensing and UAV guidance and dynamics. We show that using our proposed optimization criterion can successfully improve the landing-mission success probability while avoiding collisions with obstacles in real-time.

StyleGAN is able to generate highly realistic images in a variety of domains, and therefore much recent work has focused on understanding how to use the latent spaces of StyleGAN to manipulate generated and real images. In this talk, I will present our recent paper "StyleCLIP: Text-Driven Manipulation of StyleGAN Imagery". In this paper, we explore leveraging the power of recently introduced CLIP models in order to develop a text-based interface for StyleGAN image manipulation. This interface provides a great expressivity for image editing and allows to perform edits that were not possible with previous approaches.

Learned Greedy Method (LGM): A novel neural architecture for sparse coding and beyond
The fields of signal and image processing have been deeply influenced by the introduction of deep neural networks. Despite their impressive success, the architectures used in these solutions come with no clear justification, being ‘‘black box’’ machines that lack interpretability. A constructive remedy to this drawback is a systematic design of networks by unfolding well-understood iterative algorithms. A popular representative of this approach is LISTA, evaluating sparse representations of processed signals. In this paper, we revisit this task and propose an unfolded version of a greedy pursuit algorithm for the same goal, this method is known as LGM.

Complete Deep Computer Vision Methodology for Investigating Hydrodynamic Instabilities
In fluid dynamics, one of the most important research fields is hydrodynamic instabilities and their evolution in different flow regimes. Currently, three main methods are used for understanding such phenomena -- namely analytical and statistical models, experiments, and simulations -- and all of them are primarily investigated and correlated using human expertise. This presentation/work demonstrates how a major portion of this research effort could and should be analyzed using recent breakthrough advancements in the field of Computer Vision with Deep Learning. Specifically, Image Retrieval, Template Matching, Parameters Regression, and Spatiotemporal Prediction -- for the quantitative and qualitative benefits they provide. In order to do so, this research focuses mainly on one of the most representative instabilities, the Rayleigh-Taylor instability. The techniques which were developed and proved in this work can serve as essential tools for physicists in the field of hydrodynamics for investigating a variety of physical systems. Some of them can be easily applied to already existing simulation results, while others could be used via Transfer Learning to other instabilities research.

Asymmetric Loss For Multi-Label Classification
Pictures of everyday life are inherently multi-label in nature.
Hence, multi-label classification is commonly used to analyze
their content. In typical multi-label datasets, each picture contains only a few positive labels, and many negative ones. This
positive-negative imbalance can result in under-emphasizing
gradients from positive labels during training, leading to poor
In this lecture, we will introduce a novel asymmetric loss (”ASL”),
that operates differently on positive and negative samples.
The loss dynamically down-weights the importance of easy
negative samples, causing the optimization process to focus
more on the positive samples, and also enables to discard mislabeled negative samples.
We demonstrate how ASL leads to a more ”balanced” network, with increased average probabilities for positive samples, and show how this balanced network is translated to better mAP scores, compared to commonly used losses. Furthermore, we offer a method that can dynamically adjust the level
of asymmetry throughout the training.
With ASL, we reach new state-of-the-art results on three
common multi-label datasets, including achieving 86.6% on
MS-COCO. We also demonstrate ASL applicability for other
tasks such as fine-grain single-label classification and object
ASL is effective, easy to implement, and does not increase
the training time or complexity.

Non-Parametric Bayesian Deep-learning Method for Brain MRI Registration
Recently, deep neural networks (DNN) are successfully employed to predict the best deformation field by minimizing a dissimilarity function between the moving and target images. Bayesian DNN models enable safer utilization in medical imaging, improves generalization and assesses the uncertainty of the predictions. In our study, we propose a non-parametric Bayesian approach to estimate the uncertainty in DNN-based algorithms for MRI deformable registration. We demonstrated the added-value of our Bayesian registration framework on the brain MRI dataset. Further, we quantified the uncertainty of the registration and assessed its correlation with the out-of-distribution data.

He is currently working as a researcher in Alibaba Damo Academy, specialized in deep learning model optimization, including deep neural networks pruning, and network architecture search to discover very efficient models able to run in real time on any platform.
Realistic use of neural networks often requires adhering to multiple constraints on latency, energy and memory among others. In Alibaba, models deployed in production need to have a very low inference time to answer several cost constraints. In this talk we present a Neural Architecture Search (NAS) method that we have developed to construct these models by introducing Hard Constrained diffeRentiable NAS (HardCoRe-NAS), that is based on an accurate formulation of the expected resource requirement and a scalable search method that satisfies the hard constraint throughout the search. Our experiments show that HardCoRe-NAS generates state-of-the-art architectures, surpassing other NAS methods.

Omri is a computer vision researcher at the R&D team of Foresight Autonomous.
His main research topics are sensor pose estimation and 3D reconstruction. He holds his BSc in Computer Science from Ben-Gurion University.
Multi Sensor Quality Assessment Using 3D Reconstruction
Many systems have sensor redundancy thus require real time assessment of the data quality and relevance from each source. The assessment is useful when allocating the computation resources and user interface. It is difficult to reliably make such comparison between different sensor types in real time as that usually requires data registration and/or deep understanding of the observed scene.
We present a method for assessing and comparing data quality and relevancy through 3D reconstruction, such as by stereo vision. This method allows data assessment to be performed in real-time before other complex algorithms. By using this approach, we can avoid confusing data from noisy channels, and concentrate our resources on the best channel.

Using Synthetic Data for ADAS Applications and Perception Challenges
The performance of the Artificial Intelligence (AI) that powers automotive systems is directly linked to the data used to train and test it. Our research tackles the issue of using synthetic data for two different Computer Vision tasks where relevant data is hard to collect or simply doesn’t exist. We show how to train object detectors, based only on synthetic data, that has generalized from real-world data. We then show how to use synthetic data to evaluate the performance of distance estimation algorithms. The success of these two tasks paves the way for future research taking advantage of synthetic data.

Learning Multi-Scene Absolute Pose Regression with Transformers
Absolute camera pose regressors (APRs) estimate the position and orientation of a camera from the captured image alone, offering a fast, lightweight and standalone alternative to localization pipelines. However, APRs are also less accurate and are typically trained per scene. In this work, we propose a transformer-based approach for improving the accuracy of APRs while learning multiple scenes in parallel. We use encoders to aggregate activation maps with self-attention and decoders for transforming latent features and scenes encoding into candidate pose predictions. Our proposed approach achieves a new state-of-the-art localization accuracy for pose regression methods across indoor and outdoor benchmarks.

Synthetic data for dataset enhancement
"By 2024, 60% of the data used for the development of AI and analytics projects will be synthetically generated” - Erick Brethenoux, Gartner VP analyst.
As data collection and annotating is hard, tedious, and expensive, using rich, accurately annotated, synthetically generated data is gaining momentum.

Roei Herzig is a third-year CS Ph.D. student at Tel Aviv University, working with Prof. Amir Globerson and Prof. Trevor Darrell and a member of the Berkeley AI Research Lab. His research focuses on the intersection of computer vision, language, and robotics. Previously, Roei graduated magna cum laude from Tel Aviv University with MSc (CS), BSc (CS), and BSc (Physics) and worked as a deep learning researcher at Nexar and Trax for a few years. His long-term research goal is to develop compositional models that leverage inductive biases into our architectures to generalize over multiple environments, such as videos, images, and robots.
Towards Compositionality in Video Understanding
The key aspect behind compositionality is that humans understand the world as a sum of its parts. For example, objects can be broken down into pieces and events are composed of atomic actions. Our understanding of the world is naturally hierarchical and structured, and when new concepts are introduced, humans tend to decompose the familiar parts. This leads to the hypothesis that intelligent machines would need to develop a compositional understanding that is robust and generalizable. In this talk, I will present two recent projects towards achieving this goal, our ICML21 paper on synthesizing goal-oriented video and hot-off-the-press work on bringing object interactions to video transformers, called Object-Region Video Transformers (ORViT).

Weakly Supervised Sports Event Detection
WSC Sports’ main goal is developing sports events segmentation and recognition algorithms in order to automatically generate highlight videos from sports broadcasts.
A segment of an event usually includes a short time of the preparation for the play, a celebration, or any other expression of players at the end of the event. Each event can have few valid boundaries and the ideal ones are subjective.
In this presentation, we will show our method to solve this problem, how we leverage our massive raw data to train a weakly supervised model and how we evaluated this multiple solutions’ task.

MELoDee – Multi-Exponential model Learning based on Deep Neural Networks for Quantitative MRI Bio-Markers Estimation
Quantitative Diffusion-Weighted MRI (DW-MRI) analysis with the “Intra-voxel Incoherent motion” (IVIM) signal decay model shows potential to provide quantitative imaging biomarkers for various clinical applications. Nevertheless, reliable estimation of the IVIM parameters from clinical DW-MRI data remains a challenge. Recently, deep-neural-networks (DNN) based approaches for IVIM model parameters prediction demonstrated potential in obtaining more accurate and faster parameter estimates compared to classical model-fitting methods; however, these methods’ capability to generalize the IVIM model fitting to different clinical acquisition protocols is limited. To address this shortcoming, we propose a novel DNN model: “MELoDee”, which incorporates the acquisition protocol as part of the architecture. We demonstrate the added value of MELoDee compared to previously proposed DNN-based methods through simulation studies as well as in-vivo DW-MRI data.

Uncertainty Estimation in Postoperative GBM Segmentation
Glioblastoma multiforme (GBM) is the most frequent and lethal malignant brain tumor in adults. Novocure’s Tumor Treating Fields (TTFields) therapy was recently introduced as a novel therapeutic modality that significantly extends GBM patients’ life. TTFields treatment planning requires the segmentation of GBM tissues on postoperative MR images for evaluating the distribution of TTFields in the tumor. We present a novel method for the segmentation of GBM in postoperative patients which incorporates noisy labels and models the uncertainty of the segmentation. This uncertainty can be further deployed for intuitive and fast editing of the segmentation result.

Challenges in Deep Fake Detection
Deep fake images and videos are ubiquitous e.g. in social networks, Youtube and movies. Recent studies have shown rapid progress in facial manipulation, enabling attackers to manipulate the facial image of an individual and generate a new identity. As a remedy, many CNN based approaches suggest a deep fake detection classifier, capable of distinguishing between real and fake images/videos. In recent years we are witness to competitions organized and driven by large and diverse fake footage, created from different generators. Apparently, the generalization capability of the current detectors to unknown generators is still a debate in the community. In this talk I’ll present an overview of the problem focusing on the generalization task.

InsertionNet - A Scalable Solution for Insertion
Complicated assembly processes can be described as a sequence of two main activities: grasping and insertion. While general grasping solutions are common in industry, insertion is still only applicable to small subsets of problems, mainly ones involving simple shapes in fixed locations and in which the variations are not taken into consideration. Recently, RL approaches with prior knowledge (e.g., LfD or residual policy) have been adopted. However, these approaches might be problematic in contact-rich tasks since interaction might endanger the robot and its equipment. In this paper, we tackled this challenge by formulating the problem as a regression problem. By combining visual and force inputs, we demonstrate that our method can scale to 16 different insertion tasks in less than 10 minutes. The resulting policies are robust to changes in the socket position, orientation or peg color, as well as to small differences in peg shape. Finally, we demonstrate an end-to-end solution for 2 complex assembly tasks with multi-insertion objectives when the assembly board is randomly placed on a table.

FLEX, parameter free multi view human motion reconstruction
Video recordings made by multiple cameras facilitate mitigating occlusion and depth ambiguities in pose and motion reconstruction. Yet, multi-view algorithms strongly depend on camera parameters. Such a dependency becomes a hurdle once shifting to uncontrolled settings. We introduce FLEX (Free muLti-view rEconstruXion), an end-to-end parameter-free multi-view model, that does not require any camera parameters. Our key idea is that the 3D angles between skeletal parts, as well as bone lengths, are invariant to the camera position, in contrast to joint locations. We present our results on several datasets and show that in the absence of camera parameters, we outperform other algorithms by a large margin.

Foreground layer segmentation - Bridging the gap between semantic segmentation, depth and saliency
Automatic image segmentation is a well-studied and long-lasting problem in computer vision. Most of the vision community effort in this field over the years has focused on semantic segmentation of a predefined and usually small set of object or scene categories. However, much less focus has been given to the problem of foreground layer segmentation, which is a fundamental task in the photo editing and video creation community. In this talk, we overview the main challenges of this task, show why semantic segmentation fails here, and present a system which can handle the problem robustly.

Self-training for sequence Transfer Bootstrapping and State-of-the-art Placenta Segmentation
Quantitative evaluation of the placenta is important for fetal health evaluation. However, manual segmentation of the placenta is time-consuming and suffers from high observer variability. We present a method for bootstrapping automatic placenta segmentation by deep learning on different MRI sequences without requiring annotations for each scanning sequence. The method consists of automatic segmentation of one sequence followed by automatic adaptation using self-training to a new sequence with only additional unlabeled cases. It uses a novel combined contour and soft Dice loss function. The contour Dice loss and self-training approach achieve state-of-the art placenta segmentation results and sequence transfer bootstrapping.

We have based our results set on the known KITTI dataset and present a benchmark that was done on that dataset.

Learning with Weak Supervision - from fine-grained recognition to text grounding in images
Any practitioner of computer vision or machine learning in general knows - supervision is an asset, and in some cases quite an expensive one!
In this talk, we will focus on two of our recent works highlighting what can be achieved with limited supervision, be it learning to recognize new fine-grained classes with few examples after pre-training with only coarse class labels, or learning to ground (localize) arbitrary free-text phrases in images while learning from image and text pairs without any image location supervision.

Attention based change detection using transformers
Recently, attention-based neural networks have been shown to achieve state of the art results on image classification using pre training on huge datasets. We address the problem of change detection using transformers on small change detection dataset. Following the Compact Transformers introduced by Hassani et al  Our model uses both convolution and the Compact Convolutional Transformer (CCT). We show that compared to pure CNNs, the compact transformers have fewer parameters, while obtaining similar accuracies. This method is modular in terms of model configuration, and in this case, it have 4.1M parameters which is third the amount of parameters of pure CNN based model with similar accuracy. In this work we demonstrate for the, the potential of using state of the art change detection transformers-based algorithm on the CD2014 dataset

Data-Driven Approach for 3D Collision Reconstruction
Understanding what happens on the road can be tricky. Autonomous driving and road insight platforms require the ability to untangle diverse and complex dynamic scenes. At Nexar, we use crowd-sourced data to train deep-learning models to reconstruct corner-cases from monocular views taken by our network of dashcams. In this talk, we’ll discuss how we leverage vision with sensor fusion to produce full temporal 3D reconstruction of corner-cases, and how we overcome obstacles originating from monocular views. We will also see how such systems can be used as stepping stones for robust scene reconstruction even when sensor fusion is not applicable.

Brain Computer Interfaces for hand control using convolutional neural networks
Brain computer interfaces (BCIs) provide direct communication between the brain and the external world. A widely used technique for measuring brain activity is electroencephalogram (EEG). EEG measurements from a number of electrodes (here 35) over time (here 900 msec) can be represented as 3-dimensional (3-d) images and analyzed using 3-d image processing techniques. In particular, convolutional neural networks (CNN) can be trained to classify spatial-temporal EEG patterns.
We developed 3-d CNNs for EEG classification to: (1) determine whether the user wants to close / open or maintain the posture of the hands, and (2) determine whether the executed movement is the intended one. The latter is very important since BCIs are prone to mistakes. Detected errors can be corrected to improve overall accuracy. Our experiments demonstrate that CNN-EEG based error correction can improve the accuracy of CNN-EEG based BCI for hand control by more than 7%.
Our research facilitates the development of comfortable and intuitive brain-controlled hand prosthesis that may help 3 million upper limb amputees worldwide.

Synthetic-to-real domain adaptation for lane detection
Accurate lane detection, a crucial enabler for autonomous driving, currently relies on obtaining a large and diverse labeled training dataset. In this work, we explore learning from abundant, randomly generated synthetic data, together with unlabeled or partially labeled target domain data, instead. Randomly generated synthetic data has the advantage of controlled variability in the lane geometry and lighting, but it is limited in terms of photo-realism. This poses the challenge of adapting models learned on the unrealistic synthetic domain to real images. To this end we develop a novel autoencoder-based approach that uses synthetic labels unaligned with particular images for adapting to target domain data. In addition, we explore existing domain adaptation approaches, such as image translation and self-supervision, and adjust them to the lane detection task. We test all approaches in the unsupervised domain adaptation setting in which no target domain labels are available and in the semi-supervised setting in which a small portion of the target images are labeled. In extensive experiments using three different datasets, we demonstrate the possibility to save costly target domain labeling efforts. For example, using our proposed autoencoder approach on the llamas and tuSimple lane datasets, we can almost recover the fully supervised accuracy with only 10% of the labeled data. In addition, our autoencoder approach outperforms all other methods in the semi-supervised domain adaptation scenario.

Unsupervised Anomaly Detection in Semiconductor
Defect detection plays a key role in preventing yield loss excursion events in semiconductor manufacturing. In this talk we present the industry-standard detection pipeline, performed with Applied Materials electron-beam and optical inspection tools. We focus on two challenging real-world scenarios: one in which non-defective reference images of the pattern are available, and an unsupervised scenario where they are not. In the “with reference” scenario we propose an efficient method based on the internal statistics of the images. For the completely unsupervised scenario, our research is based on the recent advances in the self-supervised contrastive learning.
This research is the joint work with Dr. Ran Yacoby, Bar Dubovsky, Ore Shtalrid, Dr. Nati Ofir and Omer Granovitser
