解法:添加噪声 而如果通过 variational 采样的手段,就可以在训练阶段的 encoder 输出生成隐空间的阶段,让隐空间更加多样化,增强了泛化性(如上图中的绿色部分,通过添加噪声,整个输入空间更加多样化了) 回到主题:第二个 LOSS 到底在解决什么问题 解释完引入噪声的必要性后,就可以开始回答开篇的问题了,第二个 LOSS 的...
KL(p,q)的意思是使p接近于q。对于autoencoder,是x→h→x ̅,每个关系都是一一对应的。对于variaional autoencoder,h属于q(h)分布,对于x是用一个分布表示的,从q(h)分布中取一个分布的样本,赋值为一个h或者z,然后根据z重建出x ̅,取得样本具有随机性。 sample的过程是不可微的。 z=μ+σ⊙ε Repara...
这使得模型能够仅根据目标说话人的嵌入来生成具有新风格的语音,而无需目标说话人的大量训练数据。 AutoVC的文献支持: AutoVC的相关研究已在论文《AUTOVC: Zero-Shot Voice Style Transfer with Only Autoencoder Loss》中详细阐述。该论文提供了AutoVC的理论证明、实验验证和主观评估结果,证明了AutoVC在零样本语音风...

Koopman autoencoders are a prevalent architecture in operator learning. But, the loss functions and the form of the operator vary significantly in the literature. This paper presents a fair and systemic study of these options. Furthermore, it introduces novel loss terms. ...

Loss Landscapes of Regularized Linear Autoencoders Daniel Kunin, Jonathan M. Bloom, Aleksandrina Goeva, Cotton Seed Autoencoders are a deep learning model for representation learning. When trained to minimize the distance between the data and its reconstruction, linear autoencoders (LAEs) learn the...
autoencoderssuggests using a custom training loop, but I am concerned about debugging this custom loop on top of thecustom layers I need to implement to tie the encoder and decoder weights. Surely an architecture that is over a decade old has been integrated into ...
Variational Autoencoder with Tensorflow – II – an Autoencoder with binary-crossentropy loss I have discussed basics of Autoencoders. We have also set up a simple Autoencoder with the help of the functional Keras interface to Tensorflow 2. This worked flawlessly and we co...
