Introduction Mediator pattern is a behavioral design pattern, which is an effective way to reduce the coupling degree between classes.It is generally used when there is a close connection between multiple classes.First let's look at its definition: Define an object that encapsulates how a set of objects interact. Mediator promotes loose coupling by keeping objects from referring to each other explicitly, and it lets you vary their interaction independently.A series
Definition: Encapsulates a series of object interactions with a mediation object. Mediators make the objects interact without display, thus making their coupling loose and changing their interactions independently. Mediator mode consists of the following parts: Mediator abstract mediator role abstract mediator roles define a unified interface for communication between colleague roles. Concrete Mediator Specific Mediator Role The specific mediator role realizes cooperative behavior by coordinating each colleague role, so it
Original Work: 《Patch-based Probabilistic Image Quality Assessment for Face Selection and Improved Video-based Face 》 The main idea of this paper is to divide the human face into many 8×8 small blocks. The author thinks that each block represents a different part of the face, extracts the first three AC components of the block respectively, and then

1. Download dlib library and download feature extraction model.
1. Introduction to iterator pattern Iterator Pattern, also known as Cursor pattern, is one of the behavioral design patterns. comes from accessing containers, such as list, Map, array, etc. in java. we know that access to container objects must be varied, so we encapsulate traversal methods in containers or do not provide traversal methods. 1. If we encapsulate the traversal method into a container, it will take on too many

Keras is a highly modularized neural network library, which is implemented in Python and can run on both TensorFlow and Theano.It aims to allow users to carry out the fastest prototype experiment and make the process of turning ideas into results the shortest.Theano and TensorFlow's calculation charts support more general calculations, while Keras specializes in in-depth learning.Theano and TensorFlow are more like in-depth learningNumPy and Keras are Scikit-learn in this field.
1. Introduction to Keras Tool Library 1.1keras IntroductionWhat I'm telling you today is keras. keras is now a very popular tool library, including the fact that tensorflow has incorporated keras into its main code. You can directly tf.keras and call the tool library directly.The reason why keras is mentioned separately is that keras has its unique application scenarios such as laboratories, data competitions and other small environments. Using keras, engineers can spend more time on designing network models instead of coding, and keras is one of the most accessible tool libraries of all.
