Trainable and Explainable Simplicial Map Neural Networks: Overcoming Limitations and Enhancing Training

Core Concepts
Simplicial Map Neural Networks (SMNNs) address limitations through a new training procedure, enhancing efficiency and generalization.
1. Introduction AI methods have advanced, leading to complex self-regulated AI models. Explainable Artificial Intelligence (XAI) aims to provide transparent explanations. 2. Background Simplicial complexes consist of vertices and simplices. Simplicial maps are used for classification tasks. 3. The unknown boundary and the function ๐œ‘๐‘ˆ Introduces a method to compute a function approximating ๐œ‘ without a convex polytope. 4. Training SMNNs Proposes learning ๐œ‘(0)๐‘ˆ using gradient descent to minimize loss function.

"SMNNs present some bottlenecks for their possible application in high-dimensional datasets." "SMNNs are explainable models since all decision steps to compute the output of SMNNs are understandable and transparent."
