On Recoverability of Graph Neural Network Representations

1 code implementation30 Jan 2022 Maxim Fishman, Chaim Baskin, Evgenii Zheltonozhskii, Ron Banner, Avi Mendelson

Despite their growing popularity, graph neural networks (GNNs) still have multiple unsolved problems, including finding more expressive aggregation methods, propagation of information to distant nodes, and training on large-scale graphs.

End-to-End Referring Video Object Segmentation with Multimodal Transformers

2 code implementations29 Nov 2021 Adam Botach, Evgenii Zheltonozhskii, Chaim Baskin

Due to the complex nature of this multimodal task, which combines text reasoning, video understanding, instance segmentation and tracking, existing approaches typically rely on sophisticated pipelines in order to tackle it.

Contrast to Divide: Self-Supervised Pre-Training for Learning with Noisy Labels

1 code implementation25 Mar 2021 Evgenii Zheltonozhskii, Chaim Baskin, Avi Mendelson, Alex M. Bronstein, Or Litany

In this paper, we identify a "warm-up obstacle": the inability of standard warm-up stages to train high quality feature extractors and avert memorization of noisy labels.

Single-Node Attack for Fooling Graph Neural Networks

1 code implementation6 Nov 2020 Ben Finkelshtein, Chaim Baskin, Evgenii Zheltonozhskii, Uri Alon

When the adversary is allowed to pick a specific attacker node, the attack is even more effective.

Self-Supervised Learning for Large-Scale Unsupervised Image Clustering

1 code implementation24 Aug 2020 Evgenii Zheltonozhskii, Chaim Baskin, Alex M. Bronstein, Avi Mendelson

Unsupervised learning has always been appealing to machine learning researchers and practitioners, allowing them to avoid an expensive and complicated process of labeling the data.

no code implementations19 Apr 2020 Alex Karbachevsky, Chaim Baskin, Evgenii Zheltonozhskii, Yevgeny Yermolin, Freddy Gabbay, Alex M. Bronstein, Avi Mendelson

Convolutional Neural Networks (CNNs) have become common in many fields including computer vision, speech recognition, and natural language processing.


Colored Noise Injection for Training Adversarially Robust Neural Networks

no code implementations4 Mar 2020 Evgenii Zheltonozhskii, Chaim Baskin, Yaniv Nemcovsky, Brian Chmiel, Avi Mendelson, Alex M. Bronstein

Even though deep learning has shown unmatched performance on various tasks, neural networks have been shown to be vulnerable to small adversarial perturbations of the input that lead to significant performance degradation.

Loss Aware Post-training Quantization

2 code implementations17 Nov 2019 Yury Nahshan, Brian Chmiel, Chaim Baskin, Evgenii Zheltonozhskii, Ron Banner, Alex M. Bronstein, Avi Mendelson

We show that with more aggressive quantization, the loss landscape becomes highly non-separable with steep curvature, making the selection of quantization parameters more challenging.


Smoothed Inference for Adversarially-Trained Models

2 code implementations17 Nov 2019 Yaniv Nemcovsky, Evgenii Zheltonozhskii, Chaim Baskin, Brian Chmiel, Maxim Fishman, Alex M. Bronstein, Avi Mendelson

In this work, we study the application of randomized smoothing as a way to improve performance on unperturbed data as well as to increase robustness to adversarial attacks.

CAT: Compression-Aware Training for bandwidth reduction

1 code implementation25 Sep 2019 Chaim Baskin, Brian Chmiel, Evgenii Zheltonozhskii, Ron Banner, Alex M. Bronstein, Avi Mendelson

Our method trains the model to achieve low-entropy feature maps, which enables efficient compression at inference time using classical transform coding methods.

1 code implementation26 May 2019 Brian Chmiel, Chaim Baskin, Ron Banner, Evgenii Zheltonozhskii, Yevgeny Yermolin, Alex Karbachevsky, Alex M. Bronstein, Avi Mendelson

We analyze the performance of our approach on a variety of CNN architectures and demonstrate that FPGA implementation of ResNet-18 with our approach results in a reduction of around 40% in the memory energy footprint, compared to quantized network, with negligible impact on accuracy.

UNIQ: Uniform Noise Injection for Non-Uniform Quantization of Neural Networks

no code implementations29 Apr 2018 Chaim Baskin, Eli Schwartz, Evgenii Zheltonozhskii, Natan Liss, Raja Giryes, Alex M. Bronstein, Avi Mendelson

We present a novel method for neural network quantization that emulates a non-uniform $k$-quantile quantizer, which adapts to the distribution of the quantized parameters.


Streaming Architecture for Large-Scale Quantized Neural Networks on an FPGA-Based Dataflow Platform

no code implementations31 Jul 2017 Chaim Baskin, Natan Liss, Evgenii Zheltonozhskii, Alex M. Bronshtein, Avi Mendelson

Using quantized values enables the use of FPGAs to run NNs, since FPGAs are well fitted to these primitives; e. g., FPGAs provide efficient support for bitwise operations and can work with arbitrary-precision representation of numbers.
