Build your own decision model
Nish Tahir shows how to turn a small Qwen model into a fixed-choice decision model by masking outputs to allowed tokens, then evaluates and fine-tunes it on CommonsenseQA. Because the raw token probabilities are overconfident, he applies temperature scaling so the reported confidence better matches actual accuracy.
Python 3.15 for Data Scientists: Lazy Imports, frozendict, and Tachyon
Python 3.15 adds lazy imports, a built-in frozendict, and the Tachyon profiler. Learn how data scientists can use each, with before-and-after code.
Building a lift scheduling algorithm in Python
The post demonstrates how to implement a multi-elevator scheduling algorithm in Python using the LOOK algorithm to prevent out-of-order directional stops. It further explores multi-lift optimization by separating system concerns between a Dispatcher and a LiftController state machine to assign requests based on weighted cost functions.
