PyData provides a forum for the international community of users and developers of data analysis tools to share ideas and learn from each other. The global PyData network promotes discussion of best practices, new approaches, and emerging technologies for data management, processing, analytics, and visualization. PyData communities approach data science using many languages, including (but not limited to) Python, Julia, and R.

Main Talks
1. Michael Poluektov - Squeezing Intelligence out of a Fixed Compute Budget for ARC-AGI-3
  An introduction to the ARC-AGI-3 competition, why it's relevant, and how the lessons learned from competing translate to the real world. The talk will centre around co-optimising the model, inference engine and harness for modern LLMs. We will compare different context management techniques employed by the participants, and the methods used to increase end-to-end decode throughput, including REAP, quantisation scheme selection, KV-cache offloading and request scheduling, and speculative decoding
2. Anton Borisov - Snakes, Arrows and Other Curious Games in Apache Fluss
  Building a Python client for Apache Fluss turns out to be a curious game of snakes, arrows, and a little Rust.
  In this talk, we'll explore how Python, Apache Arrow, and Rust come together to bring Fluss into the Python data ecosystem, uncovering a few interesting engineering trade-offs and surprises along the way.
