Question

我想使用条件变量自动编码器来生成鸡尾酒配方。我修改了this repo中的代码，以便它可以读取我自己的数据。输入是所有可能成分的数组，因此大多数条目的值为0.如果存在一种成分，则得到的值是标准化量为250 ml的值。最后一个指标是剩下的＆＃39;剩下的＆＃39;确保鸡尾酒总是增加1。

示例：

0,0.0,0.0,0.24,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.6,0.0,0.0,0.0,0.0,0.0,0.06,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.088,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0120000000000000

具有softmax激活功能的输出看起来有点像这样：

如何确保这些值仅分布在几种成分中，其余成分为0，与输入相似？这是改变激活功能的问题吗？

谢谢：）

我不确定你想在这里使用概率。您似乎正在对某些特定值进行回归。因此，不使用softmax是有意义的，并使用简单的均方误差损失。

请注意，如果您的损失中某些值总是有偏差，您可以在损失中使用额外的重量，或使用一些抽象（例如Keras＆＃39; class_weight）。

对于此任务，您可以考虑使用Keras，特别是对于此任务，它是有意义的。检查主人的示例：https://github.com/keras-team/keras/blob/master/examples/variational_autoencoder.py

对于此任务，使用GAN实际上是有意义的：https://github.com/keras-team/keras/blob/master/examples/mnist_acgan.py。你可以让它区分一个随机的鸡尾酒和一个真实的鸡尾酒。鸡尾酒。它将学会区分这两者，并且在此过程中，它将训练重量，以便能够创建一个能为您生成鸡尾酒的发电机！
