title: K fold cross validation using keras
body: <p>It seems that k-fold cross validation in convn net is not taken seriously due to huge running time of the neural network. I have a small data-set and I am interested in doing k-fold cross validation using the example given <a href="https://gist.github.com/fchollet/0830affa1f7f19fd47b06d4cf89ed44d" rel="noreferrer">here</a>. Is it possible? Thanks.</p>
