project managers or system designers, the control-level encapsulation is generally used as the prophase work of system development, and is the preparatory work before the user function design begins. This can only be understood when you understand the meaning of the Data control encapsulation. The functionality, and the system, of the underlying control encapsulation will significantly affect the workload of subsequent development and play a role throughout the life cycle of the project.

The cross-entropy cost function (cross-entropy) is a way to measure the predicted and actual values of an artificial neural network (ANN). Compared with the two-time cost function, it can promote the training of Ann more effectively. Before introducing the cross-entropy cost function, this paper briefly introduces two cost

Some specific implementations of the Java collection class because the underlying data store is based on arrays, and as the number of elements increases, the cost of resizing is significant. As the collection element grows to an upper limit, it may be possible to adjust its size to a performance issue.When the collection element reaches the maximum value of the internal array, a new array needs to be created. and the old array elements are copied to t
