三、核心功能详解：从文本预处理到情感预测

3.1 Twitter文本预处理机制

Twitter文本包含大量特殊元素，需要专门处理以确保模型准确率：

def preprocess_tweet(text):
    """
    推文专用预处理函数，处理用户名、链接、特殊符号
    
    参数:
        text (str): 原始推文文本
        
    返回:
        str: 预处理后的文本
    """
    processed_tokens = []
    for token in text.split(" "):
        # 替换@用户名
        if token.startswith('@') and len(token) > 1:
            processed_tokens.append('@user')
        # 替换URL链接
        elif token.startswith('http'):
            processed_tokens.append('http')
        # 保留表情符号和其他特殊字符
        else:
            processed_tokens.append(token)
    return " ".join(processed_tokens)

# 示例
raw_text = "Just watched the new movie with @friend! http://movielink.com 👍"
processed_text = preprocess_tweet(raw_text)
print(processed_text)  # "Just watched the new movie with @user! http 👍"

3.2 完整推理流程实现

import numpy as np
from scipy.special import softmax

def tweet_sentiment_analysis(text, model, tokenizer, preprocess=True):
    """

        preprocess (bool): 是否进行预处理
        
    返回:
        dict: 包含各情感类别及概率的结果
    """
    # 预处理
    if preprocess:
        text = preprocess_tweet(text)
    
    # 文本编码
    encoded_input = tokenizer(
        text,
        return_tensors='pt',
        truncation=True,
        max_length=514,
        padding='max_length'
    )
    
    # 模型推理
    with torch.no_grad():  # 关闭梯度计算，提升速度
        output = model(**encoded_input)
    
    # 后处理
    scores = output[0][0].numpy()
    scores = softmax(scores)
    
    # 结果格式化
    labels = ["Negative", "Neutral", "Positive"]
    result = {
        "text": text,
        "sentiment": labels[np.argmax(scores)],
        "scores": {
            labels[i]: float(np.round(scores[i], 4)) 
            for i in range(len(labels))
        },
        "confidence": float(np.round(np.max(scores), 4))
    }
    
    return result

# 测试
sample_text = "I love using this model! It's incredibly accurate. 😍"
result = tweet_sentiment_analysis(sample_text, model, tokenizer)
print(result)

7.3 模型部署问题

问题	原因	解决方案
模型加载慢	模型文件大，IO速度慢	1. 使用模型缓存 2. 转换为ONNX格式 3. 启用模型并行加载
内存溢出	批处理过大，序列过长	1. 减小批处理大小 2. 缩短序列长度 3. 使用量化技术
推理延迟高	GPU利用率低	1. 优化批处理大小 2. 使用TensorRT加速 3. 模型蒸馏
多线程冲突	PyTorch多线程问题	1. 设置OMP_NUM_THREADS=1 2. 使用进程池代替线程池

八、模型微调：领域适配与性能提升

8.1 微调数据集准备

def prepare_sentiment_dataset(tweets, labels, tokenizer, max_length=128):
    """准备情感分析微调数据集"""
    # 标签映射
    label_map = {"negative": 0, "neutral": 1, "positive": 2}
    encoded_labels = [label_map[label.lower()] for label in labels]
    
    # 文本编码
    encodings = tokenizer(
        tweets,
        truncation=True,
        max_length=max_length,
        padding='max_length',
        return_attention_mask=True,
        return_tensors='pt'
    )
    
    # 创建数据集类
    class SentimentDataset(Dataset):
        def __init__(self, encodings, labels):
            self.encodings = encodings
            self.labels = labels
            
        def __len__(self):
            return len(self.labels)
            
        def __getitem__(self, idx):
            item = {key: torch.tensor(val[idx]) for key, val in self.encodings.items()}
            item['labels'] = torch.tensor(self.labels[idx])
            return item
    
    # 创建数据集
    dataset = SentimentDataset(encodings, encoded_labels)
    
    # 划分训练集和验证集
    train_size = int(0.8 * len(dataset))
    val_size = len(dataset) - train_size
    train_dataset, val_dataset = random_split(dataset, [train_size, val_size])
    
    return train_dataset, val_dataset

8.2 微调参数配置

    )
    
    # 定义评估指标
    def compute_metrics(eval_pred):

        precision = precision_score(labels, predictions, average='weighted')
        recall = recall_score(labels, predictions, average='weighted')
        
        return {
            "accuracy": accuracy,
            "f1": f1,
            "precision": precision,
            "recall": recall
        }
    
    # 训练器
    trainer = Trainer(
        model=model,
        args=training_args,
        train_dataset=train_dataset,
        eval_dataset=val_dataset,
        compute_metrics=compute_metrics
    )
    
    # 开始训练
    trainer.train()
    
    # 保存最佳模型
    trainer.save_model(output_dir)
    
    return trainer.evaluate()
