Vision layers 1)Upsample CLASS torch.nn.Upsample(size=None, scale_factor=None, mode='nearest', align_corners=None) 上采样一个给定的多通道的 1D (temporal,如向量数据), 2D (spatial,如jpg.png等图像数据) or 3D (volumetric,如点云数据)数据 假设输入数据的格式为minibatch x channels x [optional dept
各种优化器的比较 莫烦的对各种优化通俗理解的视频 import torch import torch.utils.data as Data import torch.nn.functional as F from torch.autograd import Variable import matplotlib.pyplot as plt # 超参数 LR = 0.01 BATCH_SIZE = EPOCH = # 生成假数据 # torch.unsqueeze() 的作用是将一维变二维,torc
retain_graph参数的作用 官方定义: retain_graph (bool, optional) – If False, the graph used to compute the grad will be freed. Note that in nearly all cases setting this option to True is not needed and often can be worked around in a much more efficient way. D
真正掌握一种算法,最实际的方法,完全手写出来. LSTM(Long Short Tem Memory)特殊递归神经网络,神经元保存历史记忆,解决自然语言处理统计方法只能考虑最近n个词语而忽略更久前词语的问题.用途:word representation(embedding)(词语向量).sequence to sequence learning(输入句子预测句子).机器翻译.语音识别等. 100多行原始python代码实现基于LSTM二进制加法器.https://iamtrask.github.
