Beyond Accuracy: A Stability-Aware Metric for Multi-Horizon Forecasting

TL;DR Traditional forecasting models optimize only for accuracy, ignoring an important issue: predictions that fluctuate significantly from day to day undermine confidence in production. This paper introduces the AC score metric that balances accuracy and temporal stability, achieving 91% reduction in forecast volatility while improving multi-step prediction accuracy by up to 26%.

A Look at Runnable Directories: The Solution to the Monorepo vs Multi-repo Debate

Ask any engineering team that has scaled past a few dozen developers: how do you organize your code? The answer shapes everything from build times to team velocity to system reliability.

The industry settled into two camps. Monorepos offer consistency but struggle with scale. Multi-repos provide independence but create coordination overhead. Both work. Neither solves the underlying trade-offs between modularity and unified workflows.
