Learn to create Deep Learning models in Python What you’ll learn: Deep Learning and Artificial Neural Networks Theory Types of Activation Functions Creating Artificail Neural Network (ANN)using Activation functions Tensof flow and keras Introduction ...
One of the main differences with modern deep learning is that the brain encodes information in spikes rather than continuous activations. snnTorch is a Python package for performing gradient-based learning with spiking neural networks. It extends the capabilities of PyTorch, taking advantage of its ...
