最近用pytorch写了一下kaggle入门的比赛:Dogs_vs_Cats 代码在个人github: https://github.com/JackwithWilshere/Kaggle-Dogs_vs_Cats_PyTorch 1.数据data 数据处理部分用的pytorch的Dataset, DogCat.py代码如下: import os import random from PIL import Image import torch.utils.data as data import numpy as ...
ADABOOST vs. GDBT vs. XGBOOST BOOST ADABOOST 简介版本: ADABOOST VS GBDT. GBDT XGBOOST 1. Regression Tree (CART) 分类树 为什么是回归树 GBDT的核心在于累加所有树的结果作为最终结果,就像前面对年龄的累加(-3是加负3),而分类树的结果显然是没办法累加的,所以GBDT中的树都是回归树,不是分类树 解释...
官方网站:https://www.kaggle.com/c/dogs-vs-cats-redux-kernels-edition/data 方法 利用pytorch构建CNN神经网络模型,进行交叉验证(没有使用测试机)。 一、数据的路径结构 不同类别放置于不同的路径,pytorch自动识别并利用One-Hot进行编码,此次路径结构如下。

Further, data augmentation technique boosts the efficiency tremendously by extending the dataset with reoriented features from the same images. To untangle the same problem, Transfer Learning is also a compelling technique in which all the layers, neurons in each layer, weights of each neuron and ...
首先,图片数据来源kaggle,在网站上搜索Dogs vs. Cats很多相关图片集,找一个下载下来。 我这里采用的数据集是: Train:4000张cat + 4000张dog Test:1000张cat + 1000张dog Pytorch版本:(torch 1.3.1+cpu) + (torchvision 0.4.2+cpu) 步骤: 1. 重定义我们的Dataset 2. 定义我们的Pytorch CNN结构 3. 利用定...
