Lessons from neuroscience: one algorithm for all kinds of learning<br/>
Looking for better representations of the input (features)<br/>
Feature learning via sparse coding (sparse linear combinations. Edge detection, quantitatively similar to primary visual cortex)<br/>
Then learning features hierarchies (several layers. "sparse DBN" "deep belief nets")<br/>
Scaling see 25'07 (algos) ; using GPUs<br/>
Learning recursive representations. "Generic" hierarchies on text doesn't make sense; learn feature vector that represent sentences
