以防止它从一个码向量到另一个码向量过于频繁地波动。而β是一个超参数,which controls the reluctance to change the code corresponding to the encoder output. 改变的地方是对codebook使用指数移动平均(exponential moving average)更新,即上面损失函数的第二项。 # 3 Method 本文提出的方法遵循两阶段的方法: 首...
2)感觉paper里的model实际在training的过程中应该还有很多details,预感effective的hierarchical latents不会很好训练(paper没有给出自己的source code,给出的code reference中,没有对autoregressive prior training的部分,然而这部分我最模糊...)

to the chosen codebook vector to prevent it from fluctuating too frequently from one code vector to another. The overall objective is described in equation 2, where e is the quantized code for the training example x, E is the encoder function and D is the decoder function. The operator...
