Manifold-based tools: ISOMAP algorithm

Author: Matteo Alberti   In this tutorial, we want to open a miniseries dedicated to Manifold-based dimensionality reductions tools. So let’s start by understanding what a Manifold is and when it is important without deepening the underlying mathematics. “Manifold is a mathematical space that on small scale resembles the Euclidean space of a specific dimension” […]

Tensor Building

Author: Andrea Mercuri The fundamental type of PyTorch is the Tensor just as in the other deep learning frameworks. By adopting tensors to express the operations of a neural network is useful for two a two-pronged purpose: both tensor calculus provides a very compact formalism and parallezing the GPU computation very easily. Tensors are generally […]
