class minerva.models.nets.resnet_1d.ConvolutionalBlock(in_channels, activation_cls=None)

Bases: torch.nn.Module

Parameters:

  • in_channels (int)

  • activation_cls (torch.nn.Module)

forward(x)
class minerva.models.nets.resnet_1d.ResNet1DBase(resnet_block_cls=ResNetBlock, activation_cls=torch.nn.ReLU, input_shape=(6, 60), num_classes=6, num_residual_blocks=5, reduction_ratio=2, learning_rate=0.001)

Bases: minerva.models.nets.base.SimpleSupervisedModel

Simple pipeline for supervised models.

This class implements a very common deep learning pipeline, which is composed by the following steps:

  1. Make a forward pass with the input data on the backbone model;

  2. Make a forward pass with the input data on the fc model;

  3. Compute the loss between the output and the label data;

  4. Optimize the model (backbone and FC) parameters with respect to the loss.

This reduces the code duplication for autoencoder models, and makes it easier to implement new models by only changing the backbone model. More complex models, that does not follow this pipeline, should not inherit from this class. Note that, for this class the input data is a tuple of tensors, where the first tensor is the input data and the second tensor is the mask or label.

Initialize the model with the backbone, fc, loss function and metrics. Metrics are used to evaluate the model during training, validation, testing or prediction. It will be logged using lightning logger at the end of each epoch. Metrics should implement the torchmetrics.Metric interface.

Parameters

backbonetorch.nn.Module

The backbone model. Usually the encoder/decoder part of the model.

fctorch.nn.Module

The fully connected model, usually used to classification tasks. Use torch.nn.Identity() if no FC model is needed.

The function used to compute the loss.

learning_ratefloat, optional

The learning rate to Adam optimizer, by default 1e-3

flattenbool, optional
