Accelerated Parameter-Free Stochastic Optimization

no code implementations31 Mar 2024 Itai Kreisler, Maor Ivgi, Oliver Hinder, Yair Carmon

We propose a method that achieves near-optimal rates for smooth stochastic convex optimization and requires essentially no prior knowledge of problem parameters.

ZeroSCROLLS: A Zero-Shot Benchmark for Long Text Understanding

1 code implementation23 May 2023 Uri Shaham, Maor Ivgi, Avia Efrat, Jonathan Berant, Omer Levy

We introduce ZeroSCROLLS, a zero-shot benchmark for natural language understanding over long texts, which contains only test and small validation sets, without training data.

DoG is SGD's Best Friend: A Parameter-Free Dynamic Step Size Schedule

1 code implementation8 Feb 2023 Maor Ivgi, Oliver Hinder, Yair Carmon

Empirically, we consider a broad range of vision and language transfer learning tasks, and show that DoG's performance is close to that of SGD with tuned learning rate.

Efficient Long-Text Understanding with Short-Text Models

1 code implementation1 Aug 2022 Maor Ivgi, Uri Shaham, Jonathan Berant

Transformer-based pretrained language models (LMs) are ubiquitous across natural language understanding, but cannot be applied to long sequences such as stories, scientific articles and long documents, due to their quadratic complexity.

Scaling Laws Under the Microscope: Predicting Transformer Performance from Small Scale Experiments

no code implementations13 Feb 2022 Maor Ivgi, Yair Carmon, Jonathan Berant

Neural scaling laws define a predictable relationship between a model's parameter count and its performance after training in the form of a power law.

SCROLLS: Standardized CompaRison Over Long Language Sequences

2 code implementations10 Jan 2022 Uri Shaham, Elad Segal, Maor Ivgi, Avia Efrat, Ori Yoran, Adi Haviv, Ankit Gupta, Wenhan Xiong, Mor Geva, Jonathan Berant, Omer Levy

NLP benchmarks have largely focused on short texts, such as sentences and paragraphs, even though long texts comprise a considerable amount of natural language in the wild.

Beyond Importance Scores: Interpreting Tabular ML by Visualizing Feature Semantics

no code implementations10 Nov 2021 Amirata Ghorbani, Dina Berenbaum, Maor Ivgi, Yuval Dafna, James Zou

We address this limitation by introducing Feature Vectors, a new global interpretability method designed for tabular datasets.

Achieving Model Robustness through Discrete Adversarial Training

1 code implementation EMNLP 2021 Maor Ivgi, Jonathan Berant

In this work, we address this gap and leverage discrete attacks for online augmentation, where adversarial examples are generated at every training step, adapting to the changing nature of the model.

Scene Graph to Image Generation with Contextualized Object Layout Refinement

no code implementations23 Sep 2020 Maor Ivgi, Yaniv Benny, Avichai Ben-David, Jonathan Berant, Lior Wolf

We empirically show on the COCO-STUFF dataset that our approach improves the quality of both the intermediate layout and the final image.
