Great talk by Dan Roth on the limitations of using LLMs for reasoning at the #KDD2025 Conference in Toronto. Being linguistically coherent is much easier than we thought (that’s what LLMs have taught us). Use LLMs to generate (Python) code to solve hard problems. #AI #LLMs #ORMS

Great tutorial on efficient and effective search-agent training at #KDD2025 in Toronto. One does not need a lot of data to train a search agent via RL (using S3 compared to R1). #LLM #RAG #RL #R1 #S3

We have liftoff at the 2025 KDD Conference in Toronto, ON. #KDD2025 I’m attending the Workshop on AI for Supply Chain relevant to our REMASC. Supply chain planning faces two sources of complexity: radical uncertainty (e.g., use scenario planning) and need for good predictions.
