gradient descent methods ①stochastic descent random gradient descentQuite unstable, try to turn the study rate down a little bit.The speed is fast, the effect and the stability are poor, need very small study rate②mini-batch descent small batch gradient descentNormalization/NormalizationFloating is still relatively large, let's try to standardize the data by subtracting its mean value by its attributes (in columns) and then dividing by its variance.

, the fuel cell stack voltage is 25-30 volts. The Fuel Cell Stack is composed of 40 batteries. The output power of each battery is 3 watts or more, the voltage is about 0.5-0.7 volts, and the current is about 6-7 amps. Because the battery has a reaction area of 10x10 cm, its power density may be less than 30 MW per square centimeter. At the same time, the 300 watt fuel cell system is also activated after water and air are added through the pump. During the demonstration, genepax used this system

path is D:/program files/emacs-21.3/bin /. If the default path is not changed, enter a file name, and a blank buffer will be created in Emacs for editing. If you enter an existing file name, the file will be opened in a new buffer for editing. That is to say, C-x C-F is a command that can be used to create or open files. It is no wonder that it is interpreted in the Emacs manual as visit a file rather than new file or open file. In most cases, it seems that you are not happy to create files in
