2014HS: 33065 Applications of Artificial Intelligence

Hi,

I think you've been answered correctly for your questions. What I could add is:

4) Watch this short video https://www.youtube.com/watch?v=BfTMmoDFXyE it gives the principle of PCA very briefly.

5) This comes from wikipedia (http://en.wikipedia.org/wiki/Recurrent_neural_network) : Unlike feedforward neural networks, RNNs can use their internal memory to process arbitrary sequences of inputs. This makes them applicable to tasks such as unsegmented connected handwriting recognition, where they have achieved the best known results

Finally you could have a look at this link http://www.quora.com/What-are-differences-between-recurrent-neural-network-language-model-hidden-markov-model-and-n-gram-language-model which might answer you questions 3 and 5.

Hope it helps. Good luck for tomorrow.
