WebMar 2, 2024 · In that case your approach seems simpler. You can even do: encoder = nn.Sequential (nn.Linear (782,32), nn.Sigmoid ()) decoder = nn.Sequential (nn.Linear (32,732), nn.Sigmoid ()) autoencoder = nn.Sequential (encoder, decoder) @alexis-jacq I want a auto encoder with tied weights, i.e. weight of encoder equal with decoder. WebThis loss combines advantages of both L1Loss and MSELoss; the delta-scaled L1 region makes the loss less sensitive to outliers than MSELoss , while the L2 region provides smoothness over L1Loss near 0. See Huber loss for more information. For a batch of size N N, the unreduced loss can be described as:
WebAs with :class:`~torch.nn.NLLLoss`, the `input` given is expected to contain*log-probabilities* and is not restricted to a 2D Tensor. The targets are given as *probabilities* (i.e. without taking the logarithm). This criterion expects a `target` `Tensor` of the same size as the`input` `Tensor`.
WebMar 22, 2024 · An electrocardiogram (ECG or EKG) is a test that checks how your heart is functioning by measuring the electrical activity of the heart.
