问题描述
我用来查找更新的w和b参数的公式：
For w:
new w = w_current - learning rate * partial derivative with respect to w
For b:
new b = b_current - learning rate * partial derivative with respect to b
从图片中，我正在为每个x和y计算具有变量tot_w和tot_b的偏导数，并将总数存储在pd_w和pd_b中。
解决方法
解释器抱怨变量i被用作函数。在tol_w语句中，我和括号之间可能缺少算术运算符。
,尝试使用"devDependencies": {
"@babel/core": "^7.11.6","@babel/preset-env": "^7.11.5","@babel/preset-es2015": "^7.0.0-beta.53","@babel/preset-react": "^7.10.4","@babel/preset-typescript": "^7.10.4","@hot-loader/react-dom": "^17.0.0-rc.2","babel-loader": "^8.1.0","babel-plugin-import": "^1.13.0","css-loader": "^4.3.0","react-hot-loader": "^4.5.3","style-loader": "^1.2.1","webpack": "^4.44.2","webpack-cli": "^3.3.12","webpack-dev-server": "^3.11.0"
}
