一、Hunyuan-MT-7B核心架構解析
1.1 基于Transformer的混合專家模型設計
Hunyuan-MT-7B采用基于Transformer的混合專家(Mixture of Experts, MoE)架構,在保持7B參數規模的同時實現接近70B模型的性能表現。其核心創新在于動態路由機制:
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# 專家網絡:每個專家是一個標準的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)])# 門控網絡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)# 計算門控權重gate_logits = self.gate(x_flat)gate_probs = F.softmax(gate_logits, dim=-1)# 選擇top-k專家top_k = 2 # 每次激活2個專家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)# 初始化輸出output = torch.zeros_like(x_flat)# 計算每個專家的容量expert_capacity = int(self.expert_capacity_factor * batch_size * seq_len / self.num_experts)# 為每個專家處理分配的tokenfor expert_idx in range(self.num_experts):# 找出分配給當前專家的tokenexpert_mask = (top_k_indices == expert_idx).any(dim=-1)expert_tokens = x_flat[expert_mask]if len(expert_tokens) > 0:# 如果超過容量,截斷if len(expert_tokens) > expert_capacity:expert_tokens = expert_tokens[:expert_capacity]expert_mask = torch.zeros_like(expert_mask)expert_mask[:expert_capacity] = True# 專家處理expert_output = self.experts[expert_idx](expert_tokens)# 計算加權輸出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 多語言注意力機制優化
Hunyuan-MT-7B針對多語言翻譯任務優化了注意力機制,引入語言感知的偏置:
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# 多語言偏置矩陣self.lang_bias = nn.Parameter(torch.randn(n_languages, n_heads, 1, 1))# 標準的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)# 計算注意力分數scores = torch.matmul(Q, K.transpose(-2, -1)) / math.sqrt(self.head_dim)# 添加語言特定偏置if lang_id is not None:lang_bias = self.lang_bias[lang_id].unsqueeze(0) # 擴展batch維度scores = scores + lang_bias# 應用注意力掩碼if attention_mask is not None:scores = scores.masked_fill(attention_mask == 0, -1e9)# 計算注意力權重attention_weights = F.softmax(scores, dim=-1)# 應用注意力到Vcontext = torch.matmul(attention_weights, V)# 合并頭并輸出context = context.transpose(1, 2).contiguous().view(batch_size, seq_len, self.d_model)return self.W_o(context)
二、訓練范式創新:五階段訓練流程
2.1 預訓練階段:多語言基礎能力構建
Hunyuan-MT-7B采用大規模多語言語料進行預訓練,涵蓋33種語言的平行語料和單語語料:
