Questions tagged [lasagne]

Lasagne provides a high-level API for creating neural networks using Theano on the backend. Questions about lasagne do not need to also utilize the "theano" tag, unless the question is specifically about Lasagne-Theano integration or the Theano backend.

Lasagne is a Python package build around expressions for neural networks training. was designed as a high-level API on top of , with the intention of making rapid prototyping of neural network architectures easier. It is similar in spirit to , which is built as a high-level API on top of //, although the main difference is that Lasagne implements only one backend, allowing it to integrate more deeply with Theano features.

Cannot make this autoencoder network function properly (with convolutional and maxpool layers)

Autoencoder networks seems to be way trickier than normal classifier MLP networks. After several attempts using Lasagne all what I get in the reconstructed output is something that resembles at its best a blurry averaging of all the images of the…

In Lasagne/Theano, do I need a 4d numpy array for a 4d Theano tensor?

I'm building a neural network with lasagne and am following the example from the github. I'm curious on how exactly to input into the network. In the example they state that the input layer is 4 dimensions and indeed it is a theano tensor4. Does…
