从Python开始学编程
说明: 本书以Python为样本,不仅介绍了编程的基本概念,还着重讲解了 编程语言的范式(面向过程、面向对象、面向函数),并把编程语言的 范式糅在Python中,让读者不仅学会Python,未来在学习其他编程语言 时也变得更加容易。(aking Python as a sample, this book not only introduces the basic concepts of programming, but also focuses on the programming language paradigm (process-oriented, object-oriented, function-oriented), and incorporates the programming language paradigm into Python, so that readers can not only learn Python, but also become easier to learn other programming languages in the future.)

俄罗斯方块强化学习实验报告
一、俄罗斯方块DQN算法实验报告1. 网络结构图1 DQN网络结构2. 超参数 GAMMA = 0.99 # decay rate of past observations 设置增强学习更新公式中的累计折扣因子 OBSERVE = 500. # timesteps to observe before training 设置观察期的迭代次数 EXPLORE = 500. # frames over which to anneal epsilon 设置探索期的观察次数 FINAL_EPSILON = 0.002 # final value of epsilon 设置ε的最终最小值 INITIAL_EPSILON = 10.0 # starting value of epsilon 设置ε的初始值 REPLAY_MEMORY = 5900 # number of previous transitions to remember 设置replay memory的容量 BATCH = 32 # size of mini batch 设置每次网络参数更新世用的样本数目 K = 1 # only select an action every Kth frame, repeat prev for others,设置几帧图像进行一次动作, # K越大让控制台输出的速度变慢,游戏画面速度变快,机器人动作的速度变越迟缓。ACTIONS = 6 # number of valid actions 游戏动作数3.实验结果训练前期的self.score分数很低150左右,EPSILON=1.0,Q_MAX= 2.061341e-02:图2 EPSILON=1.0设置超参数EPSILON=0.05在1000步迭代之后:EPSILON固定在0.04999999999999416 Q_MAX = -1.163765e-01Self.score有明显的提升,但是之后无论训练多久都没有明显提升了。图3 EPSILON=0.05设置超参数EPSILON= 0.002在1001步迭代之后:EPSILON固定在0.000004 Q_MAX = 1.728995e 02Self.score可以轻松达到200以上。图4 EPSILON=0.000004设置超参数EPSILON= 0.000001在1001步迭代之后:EPSILON固定在-0.001998997999987482 Q_MAX = 1.899879e 03Self.score可以轻松达到200以上。图5 EPSILON=-0.002 【核心代码】用DQN来玩俄罗斯方块 tetrix_DQN ├── Wrapped Game Code│ └── tetris_fun.py├── deep_q_network.py├── logs_tetris│ ├── hidden.txt│ └── readout.txt└── saved_networks ├── tetris-dqn-10000.data-00000-of-00001 ├── tetris-dqn-10000.index ├── tetris-dqn-10000.meta └── tetris-dqn-316600003 directories, 8 files

CollaborationNetwork
构建了无向加权网,并对网络的度分布、集聚系数、最短路径、度匹配度、度中心性等重要参数进行了计算,在此基础上构建了社区挖掘算法用于网络的社区发现,并采用链路预测算法构建推荐系统(An undirected weighted network is constructed, and some important parameters, such as degree distribution, aggregation coefficient, shortest path, degree matching degree and degree centrality, are calculated. On this basis, a community discovery algorithm is built for the network, and a link prediction algorithm is used to construct a recommendation system.)
