引言
随着科技的飞速发展，算法作为计算机科学的核心，其革新速度之快令人惊叹。每10分钟，都有可能诞生一项改变游戏规则的高效算法。本文将带您回顾近期的算法革新，探讨它们如何影响我们的生活和工作。
1. 深度学习算法的突破
1.1 Transformer模型
Transformer模型在自然语言处理领域取得了巨大成功，其核心思想是自注意力机制。自注意力机制允许模型在处理序列数据时，能够捕捉到数据中任意位置的信息，从而提高模型的表示能力。
import torch
import torch.nn as nn
class TransformerModel(nn.Module):
def __init__(self, vocab_size, d_model, nhead):
super(TransformerModel, self).__init__()
self.embedding = nn.Embedding(vocab_size, d_model)
self.transformer = nn.Transformer(d_model, nhead)
self.fc = nn.Linear(d_model, vocab_size)
def forward(self, src):
src = self.embedding(src)
output = self.transformer(src)
output = self.fc(output)
return output
1.2 EfficientNet
EfficientNet是一种高效的神经网络架构，通过自动调整网络宽度、深度和分辨率，在保证模型性能的同时，显著降低计算复杂度。
”`python import torch import torch.nn as nn
class EfficientNet(nn.Module):
def __init__(self, num_classes):
super(EfficientNet, self).__init__()
self.conv1 = nn.Conv2d(3, 32, kernel_size=3, stride=1, padding=1)
self.fc = nn.Linear(1280, num_classes)
