# Start epoch for adversarial training _C.TRAIN.START_EPOCH_ADV = 50

时间: 2024-04-07 21:31:19 浏览: 13
这个问题是关于对抗训练的起始 epoch 设置，参数名为 `_C.TRAIN.START_EPOCH_ADV`，其值为 50。这个参数是指模型在训练时从第 50 个 epoch 开始进行对抗训练。对抗训练是一种提高模型鲁棒性的方法，通过向输入数据中添加扰动来使模型对不同的输入具有相似的输出。通常情况下，对抗训练需要更长的训练时间和更大的计算资源，因此需要根据具体情况来进行调整。

用matlab绘制高斯色噪声情况下的频率估计CRLB，其中w(n)是零均值高斯色噪声，w(n)=0.8*w(n-1)+e(n)，e(n)服从零均值方差为se的高斯分布

以下是用matlab绘制高斯色噪声情况下频率估计CRLB的代码： ```matlab % 参数设置 N = 100; % 信号长度 se = 0.5; % 噪声方差 w = zeros(N,1); % 高斯色噪声 w(1) = randn(1)*sqrt(se); for n = 2:N w(n) = 0.8*w(n-1) + randn(1)*sqrt(se); end % 计算频率估计CRLB fs = 1; % 采样频率 df = 0.01; % 频率分辨率 f = 0:df:fs/2; % 频率范围 M = length(f); CRLB = zeros(M,1); for

python中从Excel中取的列没有了0

可能是因为Excel中的列被格式化为数字，而数字前导的0被省略了。可以在Excel中将列的格式更改为文本，这样就会保留数字前导的0。另外，在Python中读取Excel时，可以将列的数据类型指定为字符串，这样就可以保留数字前导的0。例如： ```python import pandas as pd # 读取Excel文件 df = pd.read_excel('data.xlsx', dtype={'列名': str}) # 输出列数据 print(df['列名']) ``` 其中，`dtype={'列名': str}`表示将列名为“列名”的列的数据类型指定为字符串。
