前言

🍨 本文为[🔗365天深度学习训练营]中的学习记录博客
🍖 原作者：[K同学啊]

说在前面

1）本周任务

理解文中代码逻辑并成功运行
根据自己的理解对代码进行调优，使准确率达到70%

2）运行环境：Python3.8、Pycharm2020、torch1.12.1+cu113

一、前期准备

1.1 环境安装

本文是基于Pytorch框架实现的文本分类

代码如下：

#一、准备工作
#1.1 环境安装
import torch,torchvision
print(torch.__version__)
print(torchvision.__version__)
import torch.nn as nn
from torchvision import transforms, datasets
import os, PIL,pathlib,warnings
import pandas as pdwarnings.filterwarnings("ignore")device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
print(device)

打印输出：

2.0.0+cu118
0.15.1+cu118
cuda

1.2 加载数据

代码如下：


#1.2 加载数据
#加载自定义中文数据
train_data = pd.read_csv('train.csv', sep='\t', header=None)
print(train_data.head())
#构造数据集迭代器
def custom_data_iter(texts, labels):for x, y in zip(texts, labels):yield x, ytrain_iter = custom_data_iter(train_data[0].values[:], train_data[1].values[:])

打印输出：

0 1
0 还有双鸭山到淮阴的汽车票吗13号的 Travel-Query
1 从这里怎么回家 Travel-Query
2 随便播放一首专辑阁楼里的佛里的歌 Music-Play
3 给看一下墓王之王嘛 FilmTele-Play
4 我想看挑战两把s686打突变团竞的游戏视频 Video-Play

二、数据预处理

2.1 构建词典

需要安装jieba分词库，安装语句pip install jieba

代码如下（示例）：

#二、数据预处理
#2.1 构建词典
from torchtext.vocab import build_vocab_from_iterator
from torchtext.data.utils import get_tokenizer
import jieba#中文分词方法
tokenizer = jieba.lcut
def yield_tokens(data_iter):for text,_ in data_iter:yield tokenizer(text)vocab = build_vocab_from_iterator(yield_tokens(train_iter), specials=["<unk>"])
vocab.set_default_index(vocab["<unk>"])vocab(['我', '想', '看', '和平', '精英', '上', '战神', '必备', '技巧', '的', '游戏', '视频'])
label_name = list(set(train_data[1].values[:]))
print('label name:', label_name)text_pipeline = lambda x: vocab(tokenizer(x))
label_pipeline = lambda x: label_name.index(x)print(text_pipeline('我想看和平精英上战神必备技巧的游戏视频'))
print(label_pipeline('Video-Play'))

打印输出：

Building prefix dict from the default dictionary ...

label name: ['Radio-Listen', 'Other', 'Alarm-Update', 'Travel-Query', 'FilmTele-Play', 'Weather-Query', 'Audio-Play', 'HomeAppliance-Control', 'Music-Play', 'Calendar-Query', 'TVProgram-Play', 'Video-Play']
[2, 10, 13, 973, 1079, 146, 7724, 7574, 7793, 1, 186, 28]

2.2 生成数据批次和迭代器

代码如下：

#2.2 生成数据批次和迭代器
from torch.utils.data import DataLoader
def collate_batch(batch):label_list, text_list, offsets = [], [], [0]for (_text, _label) in batch:# 标签列表label_list.append(label_pipeline(_label))# 文本列表processed_text = torch.tensor(text_pipeline(_text), dtype=torch.int64)text_list.append(processed_text)# 偏移量offsets.append(processed_text.size(0))label_list = torch.tensor(label_list, dtype=torch.int64)text_list = torch.cat(text_list)offsets = torch.tensor(offsets[:-1]).cumsum(dim=0)  # 返回维度dim中输入元素的累计和return text_list.to(device), label_list.to(device), offsets.to(device)

2.3 构建数据集

代码如下：

#2.3 构建数据集
from torch.utils.data.dataset import random_split
from torchtext.data.functional import to_map_style_datasetBATCH_SIZE = 4
train_iter = custom_data_iter(train_data[0].values[:], train_data[1].values[:])
train_dataset = to_map_style_dataset(train_iter)split_train_, split_valid_ = random_split(train_dataset,[int(len(train_dataset)*0.8), int(len(train_dataset)*0.2)])
train_dataloader = DataLoader(split_train_, batch_size=BATCH_SIZE,shuffle=True, collate_fn=collate_batch)
valid_dataloader = DataLoader(split_valid_, batch_size=BATCH_SIZE,shuffle=True, collate_fn=collate_batch)

to_map_style_dataset()函数：作用是将一个迭代式的数据集（Iterable-style dataset）转换为映射式的数据集（Map-style dataset）。这个转换使得我们可以通过索引（例如：整数）更方便地访问数据集中的元素。在 PyTorch 中，数据集可以分为两种类型：Iterable-style 和 Map-style。
●Iterable-style 数据集实现了 __ iter__() 方法，可以迭代访问数据集中的元素，但不支持通过索引访问。
●Map-style 数据集实现了 __ getitem__() 和 __ len__() 方法，可以直接通过索引访问特定元素，并能获取数据集的大小。

三、模型构建

3.1 定义位置编码器

代码如下：

#三、模型构建
#3.1 定义位置编码函数
import math
#位置编码
class PositionalEncoding(nn.Module):"实现位置编码"def __init__(self, embed_dim, max_len=500):super(PositionalEncoding, self).__init__()# 初始化Shape为(max_len,embed_dim)的PE (positional encoding)pe = torch.zeros(max_len, embed_dim)# 初始化一个tensor [max_len, 1]position = torch.arange(0, max_len, dtype=torch.float).unsqueeze(1)# 这里就是sin和cos括号中的内容，通过e和ln进行了变换div_term = torch.exp(torch.arange(0, embed_dim, 2) * (-math.log(100.0) / embed_dim))pe[:, 0::2] = torch.sin(position * div_term)  # 计算PE(pos, 2i)pe[:, 1::2] = torch.cos(position * div_term)  # 计算PE(pos, 2i+1)pe = pe.unsqueeze(0).transpose(0, 1)  # 为了方便计算，在最外面在unsqueeze出一个batch# 如果一个参数不参与梯度下降，但又希望保存model的时候将其保存下来# 这个时候就可以用register_buffer# 这里将位置编码张量注册为模型的缓冲区，参数不参与梯度下降self.register_buffer('pe', pe)def forward(self, x):# 将x和positional encoding相加。#print(x.shape)#x = x.unsqueeze(1)#print(x.shape)#print(self.pe[:x.size(0)].shape)#x = x.unsqueeze(1).expand(-1, 1, -1)  # 将 x 的形状调整为 [4, 1, 64]x = x + self.pe[:x.size(0)]return x

3.2 定义Transformer模型

代码如下：

#3.2 定义Transformer模型
from tempfile import TemporaryDirectory
from typing import Tuple
from torch import nn, tensor
from torch.nn import TransformerEncoder, TransformerEncoderLayer
from torch.utils.data import datasetclass TransformerModel(nn.Module):def __init__(self, vocab_size, embed_dim, num_class, nhead=8,d_hid=256,nlayers=12,dropout=0.1):super().__init__()self.embedding = nn.EmbeddingBag(vocab_size,embed_dim,sparse=False)self.pos_encoder = PositionalEncoding(embed_dim)#定义编码器层encoder_layers = TransformerEncoderLayer(embed_dim, nhead, d_hid, dropout)self.transformer_encoder = TransformerEncoder(encoder_layers,nlayers)self.embed_dim = embed_dimself.linear = nn.Linear(embed_dim*4, num_class)def forward(self, src, offsets, src_mask=None):src = self.embedding(src, offsets)src = self.pos_encoder(src)output = self.transformer_encoder(src, src_mask)output = output.view(4, embed_dim * 4)output = self.linear(output)return output

3.3 初始化模型

代码如下：

#3.3 初始化模型
vocab_size = len(vocab)
embed_dim = 64
num_class = len(label_name)model = TransformerModel(vocab_size, embed_dim, num_class).to(device)

3.4 定义训练函数

代码如下：


#3.4 定义训练函数
import time
def train(dataloader):model.train()total_acc, train_loss, total_count = 0, 0, 0log_interval = 300start_time = time.time()for idx, (text, label, offsets) in enumerate(dataloader):predicted_label = model(text, offsets)optimizer.zero_grad()loss = criterion(predicted_label, label)loss.backward()optimizer.step()#记录loss与acctotal_acc += (predicted_label.argmax(1) == label).sum().item()train_loss += loss.item()total_count += label.size(0)if idx % log_interval == 0 and idx > 0:elapsed = time.time() - start_timeprint('| epoch{:1d} | {:4d}/{:4d} batches''train_acc {:4.3f} train_loss {:4.5f}'.format(epoch, idx, len(dataloader),total_acc / total_count, train_loss / total_count))total_acc, train_loss, total_count = 0, 0, 0start_time = time.time()

3.5 定义评估函数

代码如下：

#3.5 定义评估函数
def evaluate(dataloader):model.eval()total_acc, train_loss, total_count = 0, 0, 0with torch.no_grad():for idx, (text, label, offsets) in enumerate(dataloader):predicted_label = model(text, offsets)loss = criterion(predicted_label, label)# 记录acc和losstotal_acc += (predicted_label.argmax(1) == label).sum().item()train_loss += loss.item()total_count += label.size(0)return total_acc/total_count, train_loss/total_count

四、训练模型

4.1 模型训练

代码如下：

#四、训练模型
#4.1 模型训练
epochs = 50
criterion = torch.nn.CrossEntropyLoss()
optimizer = torch.optim.SGD(model.parameters(), lr=1e-2)for epoch in range(1, epochs+1):epoch_start_time = time.time()train(train_dataloader)val_acc, val_loss = evaluate(valid_dataloader)#获取当前的学习率lr = optimizer.state_dict()['param_groups'][0]['lr']print('-' * 69)print('| epoch {:d} | time:{:4.2f}s |'' valid_acc {:4.3f} valid_loss {:4.3f} | lr {:4.6f}'.format(epoch, time.time() - epoch_start_time,val_acc, val_loss, lr))print('-' * 69)

4.2 模型评估

代码如下：

#4.2 模型评估
test_acc, test_loss = evaluate(valid_dataloader)
print('模型准确率为：{:5.4f}'.format(test_acc))

打印输出：

模型准确率为：0.4479

五、模型调优

5.1 尝试修改了优化器为Adam，结果变得更差了，相比之下，本文任务更适合使用SGD优化器

5.2 增加了epoch数，从原来的10增加到了50

模型准确率达到了76.2%
