dlpy.applications.ResNet_Wide(conn, model_table='WIDE_RESNET', batch_norm_first=True, number_of_blocks=1, k=4, n_classes=None, n_channels=3, width=32, height=32, scale=1, random_flip=None, random_crop=None, offsets=103.939, 116.779, 123.68, random_mutation=None, reshape_after_input=None)¶ Generate a deep learning model with Wide ResNet architecture.
Wide ResNet is just a ResNet with more feature maps in each convolutional layers. The width of ResNet is controlled by widening factor k.
- Parameters
- connCAS
Specifies the CAS connection object.
- model_tablestring or dict or CAS table, optional
Specifies the CAS table to store the deep learning model.
- batch_norm_firstbool, optional
Specifies whether to have batch normalization layer before the convolution layer in the residual block. For a detailed discussion about this, please refer to this paper: He, Kaiming, et al. “Identity mappings in deep residual networks.” European Conference on Computer Vision. Springer International Publishing, 2016. Default: True
- number_of_blocksint
Specifies the number of blocks in a residual group. For example, this value is [2, 2, 2, 2] for the ResNet18 architecture and [3, 4, 6, 3] for the ResNet34 architecture. In this case, the number of blocks are the same for each group as in the ResNet18 architecture. Default: 1
- kint
Specifies the widening factor. Default: 4
- n_classesint, optional
Specifies the number of classes. If None is assigned, the model will automatically detect the number of classes based on the training set. Default: None
- n_channelsint, optional
Specifies the number of the channels (i.e., depth) of the input layer. Default: 3
- widthint, optional
Specifies the width of the input layer. Default: 32
- heightint, optional
Specifies the height of the input layer. Default: 32
- scaledouble, optional
Specifies a scaling factor to be applied to each pixel intensity values. Default: 1
- random_flipstring, optional
Specifies how to flip the data in the input layer when image data is used. Approximately half of the input data is subject to flipping. Valid Values: ‘h’, ‘hv’, ‘v’, ‘none’
- random_cropstring, optional
Specifies how to crop the data in the input layer when image data is used. Images are cropped to the values that are specified in the width and height parameters. Only the images with one or both dimensions that are larger than those sizes are cropped. Valid Values: ‘none’, ‘unique’, ‘randomresized’, ‘resizethencrop’
- offsetsdouble or iter-of-doubles, optional
Specifies an offset for each channel in the input data. The final input data is set after applying scaling and subtracting the specified offsets. Default: (103.939, 116.779, 123.68)
- random_mutationstring, optional
Specifies how to apply data augmentations/mutations to the data in the input layer. Valid Values: ‘none’, ‘random’
- reshape_after_input
Reshape, optional Specifies whether to add a reshape layer after the input layer.
- Returns
Sequential
