1.1 基于Transformer的混合专家模型设计

Hunyuan-MT-7B采用基于Transformer的混合专家(Mixture of Experts, MoE)架构，在保持7B参数规模的同时实现接近70B模型的性能表现。其核心创新在于动态路由机制：

import torch
import torch.nn as nn
import torch.nn.functional as Fclass MoELayer(nn.Module):def __init__(self, d_model, num_experts, expert_capacity_factor=1.0):super(MoELayer, self).__init__()self.d_model = d_modelself.num_experts = num_expertsself.expert_capacity_factor = expert_capacity_factor# 专家网络：每个专家是一个标准的FFNself.experts = nn.ModuleList([nn.Sequential(nn.Linear(d_model, d_model * 4),nn.GELU(),nn.Linear(d_model * 4, d_model)) for _ in range(num_experts)])# 门控网络self.gate = nn.Linear(d_model, num_experts)def forward(self, x):batch_size, seq_len, d_model = x.shapex_flat = x.reshape(-1, d_model)# 计算门控权重gate_logits = self.gate(x_flat)gate_probs = F.softmax(gate_logits, dim=-1)# 选择top-k专家top_k = 2  # 每次激活2个专家top_k_gate_probs, top_k_indices = torch.topk(gate_probs, top_k, dim=-1)top_k_gate_probs = top_k_gate_probs / top_k_gate_probs.sum(dim=-1, keepdim=True)# 初始化输出output = torch.zeros_like(x_flat)# 计算每个专家的容量expert_capacity = int(self.expert_capacity_factor * batch_size * seq_len / self.num_experts)# 为每个专家处理分配的tokenfor expert_idx in range(self.num_experts):# 找出分配给当前专家的tokenexpert_mask = (top_k_indices == expert_idx).any(dim=-1)expert_tokens = x_flat[expert_mask]if len(expert_tokens) > 0:# 如果超过容量，截断if len(expert_tokens) > expert_capacity:expert_tokens = expert_tokens[:expert_capacity]expert_mask = torch.zeros_like(expert_mask)expert_mask[:expert_capacity] = True# 专家处理expert_output = self.experts[expert_idx](expert_tokens)# 计算加权输出gate_weights = top_k_gate_probs[expert_mask][:, [i for i in range(top_k) if top_k_indices[expert_mask][i] == expert_idx]]output[expert_mask] += expert_output * gate_weights.unsqueeze(-1)return output.reshape(batch_size, seq_len, d_model)

1.2 多语言注意力机制优化

Hunyuan-MT-7B针对多语言翻译任务优化了注意力机制，引入语言感知的偏置：

class MultilingualAttention(nn.Module):def __init__(self, d_model, n_heads, n_languages=33):super(MultilingualAttention, self).__init__()self.d_model = d_modelself.n_heads = n_headsself.head_dim = d_model // n_headsself.n_languages = n_languages# 多语言偏置矩阵self.lang_bias = nn.Parameter(torch.randn(n_languages, n_heads, 1, 1))# 标准的QKV投影self.W_q = nn.Linear(d_model, d_model)self.W_k = nn.Linear(d_model, d_model)self.W_v = nn.Linear(d_model, d_model)self.W_o = nn.Linear(d_model, d_model)def forward(self, x, attention_mask=None, lang_id=None):batch_size, seq_len, _ = x.shape# 投影到Q, K, VQ = self.W_q(x).view(batch_size, seq_len, self.n_heads, self.head_dim).transpose(1, 2)K = self.W_k(x).view(batch_size, seq_len, self.n_heads, self.head_dim).transpose(1, 2)V = self.W_v(x).view(batch_size, seq_len, self.n_heads, self.head_dim).transpose(1, 2)# 计算注意力分数scores = torch.matmul(Q, K.transpose(-2, -1)) / math.sqrt(self.head_dim)# 添加语言特定偏置if lang_id is not None:lang_bias = self.lang_bias[lang_id].unsqueeze(0)  # 扩展batch维度scores = scores + lang_bias# 应用注意力掩码if attention_mask is not None:scores = scores.masked_fill(attention_mask == 0, -1e9)# 计算注意力权重attention_weights = F.softmax(scores, dim=-1)# 应用注意力到Vcontext = torch.matmul(attention_weights, V)# 合并头并输出context = context.transpose(1, 2).contiguous().view(batch_size, seq_len, self.d_model)return self.W_o(context)

二、训练范式创新：五阶段训练流程

2.1 预训练阶段：多语言基础能力构建

Hunyuan-MT-7B采用大规模多语言语料进行预训练，涵盖33种语言的平行语料和单语语料：

from transformers import Trainer, TrainingArgumentsclass MultilingualPretraining:def __init__(self, model, tokenizer, datasets):self.model = modelself.tokenizer = tokenizerself.datasets = datasets  # 包含多语言数据的字典def create_pretraining_dataset(self):"""创建多语言预训练数据集"""combined_dataset = []for lang, dataset in self.datasets.items():# 对每种语言数据进行预处理tokenized_data = self.tokenizer(dataset['text'],truncation=True,padding=True,max_length=512,return_tensors="pt")# 添加语言ID标签tokenized_data['language_ids'] = torch.full((len(tokenized_data['input_ids']),),LANG_ID_MAP[lang])combined_dataset.append(tokenized_data)return combined_datasetdef masked_language_modeling(self, text, mask_prob=0.15):"""多语言掩码语言模型任务"""tokens = self.tokenizer.tokenize(text)tokens = ['[CLS]'] + tokens + ['[SEP]']# 随机选择要掩码的位置cand_indices = [i for i, token in enumerate(tokens) if token != '[CLS]' and token != '[SEP]']random.shuffle(cand_indices)num_to_mask = min(max(1, int(len(cand_indices) * mask_prob)), len(cand_indices))masked_labels = {}for index in cand_indices[:num_to_mask]:# 80%替换为[MASK]if random.random() < 0.8:masked_token = '[MASK]'# 10%随机替换elif random.random() < 0.5:masked_token = random.choice(list(self.tokenizer.vocab.keys()))# 10%保持原词else:masked_token = tokens[index]tokens[index] = masked_tokenmasked_labels[index] = tokens[index]return tokens, masked_labels

2.2 对比预训练(CPT)：提升翻译对齐能力

Hunyuan-MT-7B引入对比预训练技术，增强语言间的对齐表示：

class ContrastivePretraining:def __init__(self, model, temperature=0.07):self.model = modelself.temperature = temperaturedef contrastive_loss(self, source_embeddings, target_embeddings):"""计算对比学习损失"""batch_size = source_embeddings.size(0)# 归一化嵌入向量source_embeddings = F.normalize(source_embeddings, dim=1)target_embeddings = F.normalize(target_embeddings, dim=1)# 计算相似度矩阵similarity_matrix = torch.matmul(source_embeddings, target_embeddings.T) / self.temperature# 创建标签：对角线元素为正样本对labels = torch.arange(batch_size).to(similarity_matrix.device)# 计算交叉熵损失loss_source = F.cross_entropy(similarity_matrix, labels)loss_target = F.cross_entropy(similarity_matrix.T, labels)return (loss_source + loss_target) / 2def forward(self, source_batch, target_batch):"""前向传播计算对比损失"""# 获取句子级别的表示（使用[CLS]token）source_outputs = self.model(**source_batch)target_outputs = self.model(**target_batch)source_embeddings = source_outputs.last_hidden_state[:, 0, :]  # [CLS] tokentarget_embeddings = target_outputs.last_hidden_state[:, 0, :]  # [CLS] tokenreturn self.contrastive_loss(source_embeddings, target_embeddings)

2.3 监督微调(SFT)：精细化翻译能力调优

class TranslationSFT:def __init__(self, model, tokenizer):self.model = modelself.tokenizer = tokenizerdef sft_training_step(self, source_texts, target_texts):"""监督微调训练步骤"""# 编码源文本和目标文本source_encodings = self.tokenizer(source_texts, truncation=True, padding=True, max_length=512,return_tensors="pt")target_encodings = self.tokenizer(target_texts,truncation=True,padding=True,max_length=512,return_tensors="pt")# 准备模型输入input_ids = source_encodings['input_ids']attention_mask = source_encodings['attention_mask']labels = target_encodings['input_ids']# 将pad token的损失忽略labels[labels == self.tokenizer.pad_token_id] = -100# 前向传播outputs = self.model(input_ids=input_ids,attention_mask=attention_mask,labels=labels)return outputs.lossdef create_translation_prompt(self, source_text, target_lang):"""创建翻译提示模板"""if 'zh' in target_lang:prompt = f"将下面的文本翻译成{target_lang}，不要额外解释。\n\n{source_text}"else:prompt = f"Translate the following text into {target_lang}, without additional explanation.\n\n{source_text}"return prompt
