Lasagne/Lasagne
Lasagne
Lasagne is a modular neural network framework and symbolic computation engine used for building and training deep learning architectures. Built as a library on top of Theano, it utilizes symbolic expression graphs and lazy evaluation to automate gradient calculations for parameter optimization.
The framework emphasizes modularity by allowing the construction of complex neural networks through the composition of independent and reusable layers. It is designed as a hardware-accelerated machine learning library that offloads intensive linear algebra operations to graphics processors to increase the speed of training and inference.
The library provides tools for defining objective functions and generating parameter updates for gradient descent. It includes capabilities for generating model predictions and a deterministic execution mode to ensure consistent results during model evaluation.
