The AI study agent that learns how you learn — RL picks the action, FSRS picks the timing, the LLM only writes the quizzes. Chrome extension · Anki export · MCP server · runs on Ollama
A gymnasium-compatible framework to create reinforcement learning (RL) environment for solving the optimal power flow (OPF) problem. Contains five OPF benchmark environments for comparable research.
Bandit algorithms
Implementation of the Adaptive Contextual Combinatorial Upper Confidence Bound (ACC-UCB) algorithm for the contextual combinatorial volatile multi-armed bandit setting.
Context Runtime — a database query planner for LLM context. Decides what a model sees before it answers; plans it, runs it through reused substrate, and learns from the outcome.
Deterministic decision-intelligence MCP server for AI agents — 17 tools (bandits/LinUCB, HiGHS LP/MIP, PageRank, Monte Carlo, CMA-ES, conformal). Sub-25ms. Zero LLM cost. 11 free, no key. Listed on the MCP Registry & Glama.
Code for our AJCAI 2020 paper: "Online Semi-Supervised Learning in Contextual Bandits with Episodic Reward".

An illustrative project including some multi-armed bandit algorithms and contextual bandit algorithms
Contextual bandit implementation using Keras
Adaptive AI companion that builds a model of each user from implicit interaction signals — keystroke dynamics, linguistic complexity, temporal patterns — and continuously adapts its responses. Custom TCN + transformer + contextual bandit, built from scratch in PyTorch.
Reinforcement learning (PPO/A2C/DQN) that dynamically tunes Anti-Money-Laundering risk-scoring weights per case — Gymnasium env, FastAPI backend, and a React training dashboard.
Bayesian multi-armed bandits for continuous prompt experimentation: Thompson sampling routes traffic to the best prompt variant and a stopping rule promotes a winner without a fixed-N A/B test. Zero dependencies, TypeScript-first.
An experience engine for AI agents. Retrieval as a contextual bandit, not a search.
Contextual bandit (LinUCB) that re-tunes PID gains for a line-following robot as its chassis changes
Contextual Multi-Armed Bandit that automates credit limit decisions for 10,000 users using Thompson Sampling — beats static limits by 30%+ with an interactive Streamlit dashboard.
A Reinforcement Learning approach to a contextual bandit problem.
