【笔记】实用机器学习 – Data 爬虫
网页数据的抓取-爬虫 实验环境 OS: windows 11 Python 3.6 Chrome (我的版本是 98.0.4758.102) 使用的python工具是 selenium. 从https://chromedriver.chromium.org/home下载对应版本的chromedriver。我的chrome版本是98,所以chromedriver也是98。把解压出来的chromedriver.exe 放到工程目录下。 参考文章: https://selenium-python-zh.readthedocs.io/en/latest/getting-started.html 测试样例 from selenium import webdriver options = webdriver.ChromeOptions() options.add_argument('headless') driver = webdriver.Chrome(executable_path="./chromedriver.exe", chrome_options=options) driver.get("https://www.baidu.com/") print(driver.title) driver.close() 流程: 首先打开一个chrome浏览器。指定chromedriver的地址 "./chromedriver.exe"。打开百度网页,输出题目。 通过百度获取天气 xpath 可以通过chrome里右键单击所需元素“检查”,后右键单击元素选择“复制”==》“复制xpath” from selenium import webdriver from selenium.webdriver.common.keys import Keys from selenium.webdriver.support.ui import WebDriverWait…
Scaled-YOLOv4: Scaling Cross Stage Partial Network
Scaled-YOLOv4: Scaling Cross Stage Partial Network In this reading notes: We have reviewed some basic model scaling method: width, depth, resolution, compound scaling. We have computed the operation amount of residual blocks, and showed the relation with input image size (square), number of layers (linear), number of filters (square). We…

DANet: Dual Attention Network for Scene Segmentatio
Abstract The paper introduces a position attention module and a channel attention module to capture global dependencies in the spatial and channel dimensions respectively. The proposed DANet adaptively integrates local semantic features using the self-attention mechanism. 摘要 本文引入了位置关注模块和通道关注模块,分别在空间和通道维度上捕捉全局依赖性。 所提出的DANet利用自注意力机制自适应地集成局部语义特征。 Outline Brief Review: attention mechanism, SE net DANet: Dual Attention Network…
Deep Learning 2: Basic Theory of Convolutional Neural Network
Objectives Deep learning is a recently hot machine learning method. The deep learning architectures are formed by the composition of several nonlinear transformations with the goal to yield more abstract and extract useful representations/features. (i) Start with a revision of the basic principle of Neural Networks, neutron structure, examples of…
