Abstract
In this seminar, I will motivate set-theoretic Neural Reasoning and present the first such neural network, the Sphere Neural Network, which achieves the rigour of symbolic-level Aristotelian syllogistic reasoning (the beginning of the history of logical reasoning) and its variants, through constructing a sphere configuration as an Euler diagram (semantic model). I will argue that, being limited by vector embeddings (spheres with zero radius), traditional Neural Reasoning (supervised deep learning) cannot achieve rigorous syllogistic reasoning. Thus, the ability to engage in rigorous syllogistic reasoning becomes the watershed between vector-based neural reasoning (using training data) and sphere-based neural reasoning (using set-theoretic semantics). Neural semantic reasoning offers a new approach to developing interpretable and reliable neural networks.
