Introducing ARFBench: A time series question-answering benchmark based on real incidents

ai, AI (Artificial Intelligence), articles, Artificial Intelligence, deep dive

By Stephan Xie, Ben Cohen, Mononito Goswami, Junhong Shen, Emaad Khwaja, Chenghao Liu, David Asker, Othmane Abou-Amal, Ameet Talwalkar More than a trillion dollars are lost every year due to system failures. To resolve them, engineers must troubleshoot outages quickly. An important task in incident response involves analyzing observability metrics, or time series data that […]

Gradient-based planning for world models at longer horizons

ai, AI (Artificial Intelligence), articles, Artificial Intelligence, deep dive

By Michael Psenka, Mike Rabbat, Aditi Krishnapriyan, Yann LeCun, Amir Bar GRASP is a new gradient-based planner for learned dynamics (a “world model”) that makes long-horizon planning practical by (1) lifting the trajectory into virtual states so optimization is parallel across time, (2) adding stochasticity directly to the state iterates for exploration, and (3) reshaping

Identifying interactions at scale for LLMs

ai, AI (Artificial Intelligence), articles, Artificial Intelligence, deep dive

By Landon Butler, Justin Singh Kang, Yigit Efe Erginbas, Abhineet Agarwal, Bin Yu, Kannan Ramchandran Understanding the behavior of complex machine learning systems, particularly Large Language Models (LLMs), is a critical challenge in modern artificial intelligence. Interpretability research aims to make the decision-making process more transparent to model builders and impacted humans, a step toward

An encoder (optical system) maps objects to noiseless images, which noise corrupts into measurements. Our information estimator uses only these noisy measurements and a noise model to quantify how well measurements distinguish objects. By Henry Pinkard, Leyla Kabuli, Eric Markley, Tiffany Chien, Jiantao Jiao, Laura Waller Many imaging systems produce measurements that humans never see
