Self-Improving Systems

📖 Summary

In this post, we introduce the LATSAgent, an implementation of LATS: Language Agent Tree Search Unifies Reasoning.. within the co_ai framework. Unlike prior agents that followed a single reasoning chain, this agent explores multiple reasoning paths in parallel, evaluates them using multidimensional scoring, and learns symbolic refinements over time. This is our most complete integration yet of search, simulation, scoring, and symbolic tuning bringing together all of our previous work on sharpening, pipeline reflection, and symbolic rules into a unified, intelligent reasoning loop.

📖 Summary

This post introduces a multidimensional reward modeling pipeline built on top of the CO_AI framework. It covers:

• ✅ Structured Evaluation Setup How to define custom evaluation dimensions using YAML or database-backed rubrics.

• 🧠 Automated Scoring with LLMs Using the ScoreEvaluator to produce structured, rationale-backed scores for each dimension.

• 🧮 Embedding-Based Hypothesis Indexing Efficiently embedding hypotheses and comparing them for contrastive learning using similarity.

• 🔄 Contrast Pair Generation Creating training pairs where one hypothesis outperforms another on a given dimension.
