not saturate, even if Zi's contribution to the second is small, and when the maximum log-likelihood is maximized, the first item causes the Zi to rise, and the second one causes the z-vector to fall all the time, in order to Get some visual sense for the second item (that summation), Log∑j exp (ZJ) can be approximated to Max J ZJ, so the approximation is based on other exp (ZK) is very small for Max J ZJ, so we can intuitively feel-log-likelihood cost funct Ion always punishes the most inaccura

small size of the neural network does not solve the problem of high difficulty is certain, than a leech of neurons less than the neural network can not solve complex AI is not surprising.The scale includes the size of the number of neural nodes and the size of each neural node connection.As of 2016, a rough rule of thumb is that the supervised deep learning algorithm typically achieves acceptable performan

Gradient Based Learning 1 Depth Feedforward network (Deep Feedforward Network), also known as feedforward neural network or multilayer perceptron (multilayer PERCEPTRON,MLP), Feedforward means that information in this neural network is only a single direction of forward propagation without feedback mechanism. 2 Rectifier Linear unit (rectified linear Unit,relu), has some beautiful properties, more suitable

If the function of high-frequency change is irregular, the problem itself is difficult from

About twenty or thirty years ago, the neural network was once a particularly fiery direction in the ML field, but it was slowly fading out for several reasons, including the following:1) relatively easy to fit, the parameters are difficult to tune, and need a lot of trick;2) Training speed is relati
