swin_v2_small

lucid.models.swin_v2_small(img_size: int = 224, num_classes: int = 1000, **kwargs) SwinTransformer_V2

The swin_v2_small function instantiates a small-sized Swin Transformer V2 model with a predefined architecture. It incorporates enhanced normalization and a more stable shifted window mechanism, making it effective for a wide range of vision tasks such as classification, object detection, and segmentation.

Total Parameters: 49,731,106

Function Signature

@register_model
def swin_v2_small(img_size: int = 224, num_classes: int = 1000, **kwargs) -> SwinTransformer_V2

Parameters

  • img_size (int, optional): The size of the input image (assumes square images). Default is 224.

  • num_classes (int, optional): The number of output classes for classification. Default is 1000.

  • kwargs (dict, optional): Additional parameters for customization, including:

    • depths (list[int]): A list specifying the number of transformer blocks in each stage. The typical default configuration is [2, 2, 18, 2], indicating that the model has 4 stages with 2, 2, 18, and 2 blocks respectively.

    • num_heads (list[int]): A list specifying the number of attention heads in each stage. The common default is [3, 6, 12, 24], allowing the model to effectively capture multi-scale information at different depths.

Returns

  • SwinTransformer_V2: An instance of the SwinTransformer_V2 class configured as a robust vision transformer.

Examples

>>> import lucid.models as models
>>> model = models.swin_v2_small()
>>> print(model)
SwinTransformer_V2(img_size=224, num_classes=1000, ...)
