computer programs to learn and recognize handwritten numbers. Although this program is only 74 lines, and does not use any special neural network library, but it can be without any human intervention, to achieve more than 96 of the handwritten digit recognition accuracy rate. In the following chapters, we will further refine our approach to achieve an accuracy rate of more than 99. In fact, the best commercially available neural network is good enoug

. Random Search. Bengio in the random search for hyper-parameter optimization that random search is more efficient than gird search. In practice, it is usually the first time to use the Gird search method, to get all the candidate parameters, and then each time from the random selection of training. Bayesian optimization. Bayesian optimization, which takes into account the experimental result values corresponding to different parameters, saves time. Compared to the Internet search is simply the
follows:
Then, the cost function after the rule is:
In our example, the cost function after the rule is:
In principle, when adding a rule-to-cost function, the mapping of the neural network will be smoother (by punishing large parameters, which will reduce the nonlinearity of the network model).
Look at the implementations in Python:# Symbolic Theano variable that represents the L1 regularization termL1 = t.sum (ABS (param)) # Symbolic Theano va
When does the deep learning model in NLP need a tree structure?Some time ago read Jiwei Li et al and others [1] in EMNLP2015 published the paper "When is the Tree structures necessary for the deep learning of representations?", This paper mainly compares the recursive neural network based on tree structure (Recursive n
