Zero-shot mono-to-binaural speech synthesis

Humans possess a remarkable ability to localize sound sources and perceive the surrounding environment through auditory cues alone. This sensory ability, known as spatial hearing, plays a critical role in numerous everyday tasks, including identifying speakers in crowded conversations and navigating complex environments. Hence,...

Chain of Agents: Large language models collaborating on long-context tasks

Over the past few years large language models (LLMs) have shown remarkable capabilities on various tasks, such as reasoning, knowledge retrieval, and generation. However, it is still challenging for LLMs to solve tasks that require long inputs, because they typically have limitations on input length, and hence, cannot utilize the...

Building AI for the pluralistic society

Modern artificial intelligence (AI) systems rely on input from people. Human feedback helps train models to perform useful tasks, guides them toward safe and responsible behavior, and is used to assess their performance. While hailing the recent AI advancements, we should also ask: which humans are we actually talking about? For AI...

Mechanism design for large language models

Generative AI and large language models (LLMs) facilitate the automated generation of assets across a variety of domains. For many use cases, several LLM agents may need to collaborate to create a joint output. A potential example is in the context of Internet ads, where advertisers might be represented by LLM agents capable of...

Mind the GAP: Geometry Aware Passthrough mitigates cybersickness

Virtual reality (VR) headsets are becoming increasingly popular, especially in environments that benefit from immersion, such as gaming and education. In part, they accomplish this by restricting the user's perception to the virtual world that they are projecting. Yet many headsets, such as Meta Quest, Apple Vision Pro, and Samsung...

Discovering new words with confidential federated analytics

Introduced by Google Research in 2020, federated analytics allows for the application of data science methods to the analysis of raw data stored locally on users’ devices so that only the aggregated results — and not data from any particular device — are made available to product engineers. This keeps users' data private, while...

Generating synthetic data with differentially private LLM inference

Differential privacy (DP) provides mathematically rigorous guarantees that an algorithm will not reveal details about an individual’s data. However, endowing algorithms with DP guarantees can add complexity to an already complex machine learning (ML) pipeline. This is especially true at the scale of modern ML, where pipelines are...

Loss of Pulse Detection on the Google Pixel Watch 3

Unwitnessed out-of-hospital cardiac arrest (OHCA), when an individual experiences a pulseless arrhythmia without nearby bystanders who could activate an emergency response on their behalf, is a seemingly intractable public health challenge. OHCA leads to millions of deaths worldwide, and it is estimated that one half to three...

Deciphering language processing in the human brain through LLM representations

How does the human brain process natural language during everyday conversations? Theoretically, large language models (LLMs) and symbolic psycholinguistic models of human language provide a fundamentally different computational framework for coding natural language. Large language models do not depend on symbolic parts of speech or...

Teaching machines the language of biology: Scaling large language models for next-generation single-cell analysis

Every human is made up of trillions of cells, each with its own function, whether it’s carrying oxygen, fighting infections, or building organs. Even within the same tissue, no two cells are exactly alike. Single-cell RNA sequencing (scRNA-seq) allows us to measure the gene expression of individual cells, revealing what each cell...

Optimizing LLM-based trip planning

Many real-world planning tasks involve both harder “quantitative” constraints (e.g., budgets or scheduling requirements) and softer “qualitative” objectives (e.g., user preferences expressed in natural language). Consider someone planning a week-long vacation. Typically, this planning would be subject to various clearly...

MUVERA: Making multi-vector retrieval as fast as single-vector search

Neural embedding models have become a cornerstone of modern information retrieval (IR). Given a query from a user (e.g., “How tall is Mt Everest?”), the goal of IR is to find information relevant to the query from a very large collection of data (e.g., the billions of documents, images, or videos on the Web). Embedding models...
