layer_random_width
Randomly vary the width of a batch of images during training
Description
Randomly vary the width of a batch of images during training
Usage
layer_random_width(
object,
factor,
interpolation = "bilinear",
seed = NULL,
...
) Arguments
| Arguments | Description |
|---|---|
| object | What to compose the new Layer instance with. Typically a Sequential model or a Tensor (e.g., as returned by layer_input()). The return value depends on object. If object is: - missing or NULL, the Layer instance is returned. - a Sequential model, the model with an additional layer is returned. - a Tensor, the output tensor from layer_instance(object) is returned. |
| factor | A positive float (fraction of original height), or a list of size 2 representing lower and upper bound for resizing vertically. When represented as a single float, this value is used for both the upper and lower bound. For instance, factor = c(0.2, 0.3) results in an output with width changed by a random amount in the range [20%, 30%]. factor=(-0.2, 0.3) results in an output with width changed by a random amount in the range [-20%, +30%]. factor = 0.2 results in an output with width changed by a random amount in the range [-20%, +20%]. |
| interpolation | String, the interpolation method. Defaults to bilinear. Supports "bilinear", "nearest", "bicubic", "area", "lanczos3", "lanczos5", "gaussian", "mitchellcubic". |
| seed | Integer. Used to create a random seed. |
| … | standard layer arguments. |
Details
Adjusts the width of a batch of images by a random factor. The input should be a 3D (unbatched) or 4D (batched) tensor in the "channels_last" image data format. By default, this layer is inactive during inference.
