Baysian Networks for Kidney Failure

A chatbot that doesn’t guess, it reasons. Built on Bayesian Networks, it supports decision-making under uncertainty by updating beliefs step by step as new information is provided. The result is transparent, adaptive reasoning that users can understand and trust.

We are often asked...

What does RootSquare do?

RootSquare builds AI systems that clean, connect, and explain complex data. Our work focuses on data deduplication, multimodal intelligence, and explainable healthcare AI.

How is your approach different from traditional AI models?

Our systems combine machine learning, multimodal reasoning, and causal models. This allows us to handle missing data, reduce bias, and provide explanations instead of black-box predictions.
