A quick guide to Amazon's papers at NeurIPS 2024

While large language models and other foundation models are well represented, traditional Amazon interests such as bandit problems and new topics such as AI for automated reasoning also get their due.

The 2024 Conference on Neural Information Processing Systems (NeurIPS) — the premier conference in the field of AI — begins today, and the Amazon papers accepted there display the breadth of the company’s AI research.

Large language models (LLMs) and other foundation models have dominated the field for the past few years, and Amazon’s papers reflect that trend, covering topics such as retrieval-augmented generation, the use of LLMs for code generation, commonsense reasoning, and multimodal models. Training methodology also emerges as an area of focus, with papers on memory-efficient training, reinforcement learning with human feedback, classification with rejection, and convergence rates in transformer models.

But Amazon’s papers also demonstrate an abiding interest in topics such as bandit problems — long a staple of Amazon’s NeurIPS submissions — and speech processing, as well as newer concerns such as the applications of machine learning to scientific computing and automated reasoning. And one paper, “B’MOJO: Hybrid state space realizations of foundation models with eidetic and fading memory”, proposes a new paradigm of machine learning, rooted in the concept of transductive learning.

LLM evaluation

SetLexSem Challenge: Using set operations to evaluate the lexical and semantic robustness of language models
Bardiya Akhbari, Manish Gawali, Nicholas Dronen

SetLexSem Challenge figure
To evaluate LLMs' robustness to semantic variation in set members, Amazon researchers and their colleagues created “deceptive” sets by sampling pairs of hypernyms (e.g., “mammal” and “vehicle”) and, from them, extracting hyponyms under three different conditions: (1) with the hyponyms as sampled; (2) with half of the set members swapped; and (3) with random sampling. LLMs exhibit a unique failure mode under the second condition (swapped), and the mean and variance in accuracy of the first condition (not swapped) are better than in the random baseline. This figure can be found in "SetLexSem Challenge: Using set operations to evaluate the lexical and semantic robustness of language models".
