Closed out the inaugural year of the Berkeley AI & Society social with a look at a new statewide police use-of-force + misconduct database built by Berkeley EECS, journalism, law, data science, and others, including at Stanford. ML+ other techniques+sweat pulled of the enormous data cleaning (1/3)

Beautiful nostalgic piece by @adityagp.bsky.social! Don't miss the end for some nice reflections. Aditya's just getting started! :)

Adam!!!!!! So nice to hear from you, and as always, you're too kind :)

My periodic reminder to my CMU friends to get someone with any inkling of UI design to fix their letter upload portal. I don't know what to pick between "Submit" and "Upload Recommendation", and the dropdown forces me to make a choice even if I don't want to. cc @andypavlo.bsky.social @domoritz.de

If you're at The Curve Conference this weekend, come dive into what the future of applied evals looks like! I'll be demo-ing EvalForge, an implementation of the "who validates the validators" paper with @weightsbiases.bsky.social

Big thanks to @capetorch.bsky.social and Anish for their work here

Who Validates the Validators? Aligning LLM-Assisted Evaluation of LLM Outputs with Human Preferences Due to the cumbersome nature of human evaluation and limitations of code-based evaluation, Large Language Models (LLMs) are increasingly being used to assist humans in evaluating LLM outputs. Yet LLM-...

First post here! I'm currently researching how LLMs can be grounded in tables, bc they're a goldmine for fresh domain data.

We've now introduced the 🎯TARGET benchmark for evaluating table retrieval in RAG pipelines, e.g. QA/factver/text2sql: target-benchmark.github.io

Thinking BM25? Think twice..🧵

SIC is so much cooler than SIG, wish they hadn’t changed it
