Hello!!
I trained an autoencoder and now I want to use that model with the trained weights for classification purposes. So, I suppose I have to freeze the weights and layer of the encoder and then add classification layers, but I am a bit confused on how to to this.
This is the AutoEncoder I trained
class AE(nn.Module):
    def __init__(self, **kwargs):
        super().__init__()
        self.encoder_hidden_layer = nn.Linear(
            in_features=kwargs["input_shape"], out_features=128
        )
        self.encoder_output_layer = nn.Linear(
            in_features=128, out_features=128
        )
        self.decoder_hidden_layer = nn.Linear(
            in_features=128, out_features=128
        )
        self.decoder_output_layer = nn.Linear(
            in_features=128, out_features=kwargs["input_shape"]
        )

    def forward(self, features):
        activation = self.encoder_hidden_layer(features)
        activation = torch.relu(activation)
        code = self.encoder_output_layer(activation)
        code = torch.relu(code)
        activation = self.decoder_hidden_layer(code)
        activation = torch.relu(activation)
        activation = self.decoder_output_layer(activation)
        reconstructed = torch.relu(activation)
        return reconstructed

Can someone help me?
Thank you
