darch for dimensionality reduction #32

Open renjithranganadhan opened 6 years ago

renjithranganadhan commented 6 years ago

I was wondering whether darch can be used for achieving dimensionality reduction. do we have any samples to refer to?

Have you checked out the autoencoder example? See here for implementation details. But also check out #14, the autoencoder implementation is unfortunately still buggy.

Thanks. Any fix for #14 ?

Sadly, no. I don't have the knowledge to fix it (I'm not the original author) and I'm not working on this project anymore, so unless someone else takes over development of this project, I don't see a fix coming. :(

You could try to turn it into a regression problem, where input equals output, and in your network you have something like a "hour-glass shaped" network. And then after training you extract the data from one of the intermediate layers.
