Cognitive ecosystem framework pairing Active Inference agent models with an Obsidian-compatible markdown knowledge graph — generates executable Python from markdown specs, runs multi-agent simulations, and auto-validates probabilistic constraints.

Hierarchical Bayesian modeling toolkit for interoceptive psychophysics (HRDT & RRST). Includes Stan models, power analysis tools, and educational resources for researchers.

Football forecasting framework to simulate the FIFA World Cup using team strength modeling and probabilistic match prediction.

Agent-based political election simulator using predictive coding

An R package for modeling asymmetric spatial associations between cell types in tissue images using a multilevel Bayesian framework.

Quantitative football value betting framework in PyTorch & C++20. Empirical Bayesian Shrinkage with Shin (1993) de-vigging, blind out-of-sample testing (+15.31% ROI at EV > 5.0%), and a 10,000-run C++20 Monte Carlo engine.

Public research and software index for Daniel Ari Friedman, with publications, code, videos, teaching resources, and citation metadata across active inference, entomology, cognitive security, and art.

Inflation forecasting during crisis periods using Bayesian Dynamic Linear Models, traditional econometrics, and machine learning. Includes data, code, and comprehensive analysis report.

The project focuses on the analysis of experimental data regarding the continuous biomass production of a cyanobacterium of the genus Nostoc. The primary objective is to understand how different cultivation factors influence biological growth over time, monitored through optical density (OD).

computational model showing how compulsive urges might arise when the brain stops listening to its own body signals, testing this idea against real physiological data like heart rate and pupil size.

Bayesian uncertainty, calibration, and hallucination-risk modeling for reliable language and multimodal AI.

Three‑level hierarchical enactive inference model of mental action (focused‑attention meditation with expert–novice profiles) with reproducible simulations and figures.

Comprehensive analysis of differential gene expression using Bayesian statistics and advanced statistical modeling techniques. The project includes scripts, data, figures, and analysis results.

Stan implementation of Lee & Sarnecka's (2010, 2011) knower-level model

R code and Stan models for "Decoupling Decision and Intensity in Visual Attention" .

Spin — a browser-based pocket lab for learning active inference and the free energy principle, with chapter modules each rendered in three switchable streams (conversational, animated, LaTeX academic). Installable PWA built on React, Vite, Framer Motion, and KaTeX, with a Vitest suite.

Customer-analytics models for Laplace: churn for subscription businesses, purchase-and-spend models for non-contractual businesses, and customer lifetime value

A repository for the R code and data used in Iwasaki et al. (2023)

Bayesian Marketing Mix Modeling project using PyMC to estimate marketing channel effectiveness through probabilistic inference, adstock transformation, uncertainty-aware ROI analysis, and seasonal trend modelling across multiple advertising channels.
