Encapsulates a series of object interactions with an intermediary object. The intermediary makes the objects interact without display, thus making the coupling loose, and can independently change the interactions between their fingers. Composition of Mediator PatternMediator Abstract Mediator Role: The abstract mediator role defines a unified interface for communication between various colleague roles.Concrete Mediator Specific Mediator Role: The specific mediator role realizes cooperative behavior by coordinating various colleague roles, so
code is as follows: #coding:utf-8 import string,os,sys import numpy as np import matplotlib.pyplot as plt import scipy.io import random import csv import tensorflow as tf import pandas as pd filename = "/home/yc/prid_2011_test/ptest.csv" data = pd.read_csv(filename,dtype='a') label = np.array(data['pid']) img_data = np.array(data['pixels']) N_sample = label.size Face_data = np.zeros((N_sample, 128*64)) Face_label=np.zeros((N_sample,40),dtype=int) for i in range(N_sample): x = img_data[i] x = np.fromstring(x, dtype=float, sep=' ') x_max = x.max() x = x/(x_max+0.0001) Face_data[i] =
brief introduction New move, Raspberry Pi 2 generation idle for a period of time.Because I like watching some movies or entertainment programs on the computer in my spare time, sometimes some friends come and several people move a small bench to watch them together … and just the living room has a large TV screen and a comfortable sofa, but I don't want to spend an extra 200 yuan per year to open the TV channel of radio and television.
Preface Learning Purpose: MediatR is What? why did he use MediatR? how do i use MediatR? MediatR is What? MediatR official website: https://github.com/jbogard/MediatR. Official Introduction: Simple mediator implementation in .NET What is "mediator/ Mediator Mode"? PS: In fact, I learned from 23 design patterns before and almost forgot them when I used less.Similar problems encountered in the past were basically solved by Observer pattern (especially after ReactiveX appeared), and this
PyTorch structure introduction A superficial understanding of PyTorch architecture cannot guarantee complete correctness, but I hope I can have an overall grasp of PyTorch from a higher level.Level is limited, if there is any mistake, please refer to the wrong, thank you!
Several Important Types Numerically Related Tensor Variable Parameter buffer (this cannot be called a type, in fact it is used to save tensor) Tensor:The calculation in PyTorch is basically based on Tensor, which can be said to be the basic calculation unit in PyTorch.
definition As can be seen from the examples in life, both QQ group and QQ Games are acting as an intermediate platform. QQ users can log in to this intermediate platform to communicate with other QQ users. Without these intermediate platforms, if we want to chat with friends, we may need to face to face.Telephone and SMS are the same, with this intermediate platform.Each user does not need to rely
scenarioBuying a house, renting a house, looking for an intermediary, and dating men and women looking for an intermediary.Use a mediation object to encapsulate a series of object interactions.Mediators make it unnecessary for objects to refer to each other explicitly, which makes them loose and can change their interaction independently.In simple terms, the original two directly referenced or dependent objects are separated, and a' intermediary' object is added in the
