In large enterprises, because of complex business, large data volume, different data formats, and complex data interaction formats, not all operations can be processed through interactive interface. Some operations require regular reading of large quantities of data, followed by a series of subsequent processing. This is the process of "batching."Batch applications typically have the following characteristics: Large data volume, ranging from

find the steepest slope, then take one step, until we continue to walk, to the most "low" point (minimum cost function convergence point).As shown above, the local optimal solution is obtained. X, y indicates that the THETA0 and theta1,z directions represent the cost function, and it is clear that the starting point is different, and the final convergence point may not be the same. Of course, if it is bowl-shaped, then the convergence point should be the same. two, the gradient descent method d

Why do we need batch processing? We don't always want to get the information we need right away, the batch allows us to start collecting information on an established process before the request is processed, such as a bank statement, which we can generate on a monthly basis and open a batch process before the user queries. Sometimes it can make the b
