Personalized LLM Decoding via Contrasting Personal Preference

Cornell Tech has secured a $7 million investment from NASA and Schmidt Sciences aimed at modernizing arXiv, a preprint repository for scientific papers. This funding will facilitate the migration of arXiv to cloud infrastructure, upgrade its outdated codebase, and develop new tools to enhance the discovery of relevant preprints for researchers.

A novel framework named SWAN has been introduced to address the memory challenges faced by Large Language Models (LLMs) during autoregressive inference, specifically targeting the Key-Value (KV) cache's substantial memory usage. SWAN employs an offline orthogonal matrix to efficiently rotate and prune the KV-cache, allowing for direct use in attention computation without requiring decompression steps.

The recent introduction of SPINE, a token-selective test-time reinforcement learning framework, addresses challenges faced by large language models (LLMs) and multimodal LLMs (MLLMs) during test-time distribution shifts and lack of verifiable supervision. SPINE enhances performance by selectively updating high-entropy tokens and applying an entropy-band regularizer to maintain exploration and suppress noisy supervision.

A recent position paper emphasizes the need for literary scholars to engage with research on large language model (LLM) interpretability, suggesting that the red team could serve as a platform for this ideological struggle. The paper argues that current interpretability standards are insufficient for evaluating LLMs.

Recent research has introduced the concept of representational stability in large language models (LLMs), focusing on how these models encode distinctions between true, false, and neither-true-nor-false content. The study assesses this stability by training a linear probe on LLM activations to differentiate true from not-true statements and measuring shifts in decision boundaries under label changes.

Recent advancements in text-to-speech (TTS) technology have led to the development of a new model called Word-level TTS Alignment by ASR-driven Attentive Reward (W3AR), which utilizes fine-grained reward signals from automatic speech recognition (ASR) systems to enhance TTS synthesis. This model addresses the limitations of traditional evaluation methods that often overlook specific problematic words in utterances.

A new study introduces an innovative pipeline for transforming public Zoom recordings into speaker-attributed transcripts, enhancing the realism of civic simulations using large language models (LLMs). This method incorporates persona profiles and action tags, significantly improving the modeling of multi-party deliberation in local government settings such as Appellate Court hearings and School Board meetings.

A new framework named Reading Comprehension Exercise Generation (RCEG) has been proposed to leverage large language models (LLMs) for automatically generating personalized English reading comprehension exercises. This framework utilizes fine-tuned LLMs to create content candidates, which are then evaluated by a discriminator to select the highest quality output, significantly enhancing the educational content generation process.
