Intelligence through reasoning

September 2021 – August 2023

This project aims to improve a Non-Axiomatic Reasoning System design and combine it with state-of-the-art Deep Learning models for perception. This allows the system to be applied in real-world environments, intending to enhance the autonomy of robots where human intervention is to be kept at a minimum. Application-wise, the system is expected to autonomously perform inspection and maintenance operations of city infrastructure such as power plants. This will ultimately lead to new digitisation technology, which can help solve environmental and societal problems.

The human’s ability to reason has evolved to adapt to difficult situations and changes in the environment faster than current AI models allow. Animals that reason effectively outsmart other species and gain key survival advantages. Non-Axiomatic Reasoning can explain most of these cognitive abilities and provides a roadmap for cognitive enhancements based on psychological and neuroscientific insights. Also, Learning can be explained as inductive reasoning using Non-Axiomatic Logic, an aspect most reasoning systems lack while being a key aspect of intelligence.
