PyImpetus is a Markov Blanket based feature subset selection algorithm that considers features both separately and together as a group in order to provide not just the best set of features but also the best combination of features

VeFloodBN: 基于离散贝叶斯网络的意大利威尼托大区市镇级洪涝风险建模。模型融合人均GDP、人口密度、坡度、河网密度、降雨频率等 12 个节点，构建因果有向无环图（DAG）；采用最大似然估计学习条件概率表，通过结构校验、马尔可夫毯与活跃路径分析保证模型合理性。支持精确变量消元，并对比拒绝采样、似然加权与吉布斯 MCMC 等近似推理方法。连续变量经分位数离散化后，实现逐市镇批量后验概率推断，利用 GeoPandas 输出空间风险热力图。针对 Top‑N 风险排名引入分层/比例采样策略，结合 Jaccard 与 Overlap 指标评估结论稳健性；同时提供单因子边际效应、稀有证据下采样效率对比及条件独立可视化，兼具可解释性与推断鲁棒性。

Personal Markov blanket and simple knowledge manager using Wikipedia. Recommends connected frontier concepts, sorts by in and out connection degree.

A K4-engine cybernetic runtime for AI swarms. Replaces semantic theater with thermodynamic constraint. Uses the K4 Algebra of Four-Fold Distinction to achieve phase-lock, prevent trajectory loss, and execute structurally coherent agent instantiation.

DMBD — PyTorch implementation of dynamic Markov blanket detection for time-series data, finding how parent/child/spouse neighborhoods and sensory, active, and internal state partitions shift over time via conditional independence tests, temporal windowing, and information-flow analysis. Follows Beck & Ramstead (2025).

A rigorous **Meta-of-Physics & Topological Grammar**, not an ad-hoc speculative model, not a rival empirical physics theory. Internal type-safety rules account for and resolve apparent contradictions.

This repository contains a collection of lab exercises and exams from the TDDE15: Advanced Machine Learning course taking at Linköping Univerity during the fall 2024. The main topics are: Bayesian Networks, Hidden Markov Models, Q-learning, REINFORCE, and Gaussian Processes.

14+ candidate semantic dualities across 6 algebraic layers, 72 primitives connected by a DAG, validated via 8 domains + 3 negative controls (DVS), Bayesian model comparison (BF=121), and a 72-bit triadic head over GPT-2 Medium / GPT-Neo

Shear the stress at the boundary , spin the truth at the core .

Cognition layer for autonomous agents — modular OSS packages for active-inference reasoning, thoughtseed competition, computational phenomenology, and workspace dynamics. Each adopts alone. Companion to elume (memory layer).

Essay pipeline triangulating Jiang Xueqin's 2026 AI lecture, William Blake's Single Vision, and Friston's Active Inference as one failure mode: pathological prior dominance. Generates a 17,000-word manuscript, 7 equations, and 14 light/dark figures from Python (uv, pytest, pandoc/xelatex).
