A 2d grid map of m rows and n columns is initially filled with water. We may perform an addLand operation which turns the water at position (row, col) into a land. Given a list of positions to operate, count the number of islands after each addLand o…

一些机器学习算法的简介 本节开始,介绍<Computer Science Theory for the Information Age>一书中第六章(这里先暂时跳过第三章),主要涉及学习以及学习的理论——VC理论.而本文主要是介绍一下什么是学习,以及一些常见的学习算法. (一)学习概念 首先,我们用一个例子来介绍什么是学习.假设我们想要用一个算法来识别不同类型的车,比如小汽车.卡车.拖拉机等.根据我们的思维以及对这个领域的知识可知道,我们可以用一系列特征来区分它们,比如我们可以用轮子的数量,发…

Self-taught 自我学习器实验报告 1.Self-taught 自我学习实验描述 自我学习是无监督特征学习算法,自我学习意味着算法能够从未标注数据中学习,从而使机器学习算法能够获得更大数量的数据,因而更有可能取得更好的性能.在本实验中,我们将按照自我学习的步骤,使用稀疏自编码器和softmax分类器去构造一个手写数字分类器. 实现流程 Step 1 :产生训输入和测试样本集 Step 2 :训练稀疏自编码器 Step 3 :提取特征 Step 4 :训练和测试softMax分类器 Ste…
