LinearClsHead

class mmcls.models.LinearClsHead(num_classes, in_channels, init_cfg={'layer': 'Linear', 'std': 0.01, 'type': 'Normal'}, *args, **kwargs)[source]

Linear classifier head.

Parameters
  • num_classes (int) – Number of categories excluding the background category.

  • in_channels (int) – Number of channels in the input feature map.

  • init_cfg (dict | optional) – The extra init config of layers. Defaults to use dict(type=’Normal’, layer=’Linear’, std=0.01).

simple_test(x, softmax=True, post_process=True)[source]

Inference without augmentation.

Parameters
  • x (tuple[Tensor]) – The input features. Multi-stage inputs are acceptable but only the last stage will be used to classify. The shape of every item should be (num_samples, in_channels).

  • softmax (bool) – Whether to softmax the classification score.

  • post_process (bool) – Whether to do post processing the inference results. It will convert the output to a list.

Returns

The inference results.

  • If no post processing, the output is a tensor with shape (num_samples, num_classes).

  • If post processing, the output is a multi-dimentional list of float and the dimensions are (num_samples, num_classes).

Return type

Tensor | list
