Tiling Verification

[leemorton]

Hi, I configure Tiling against EfficientAd however cannot see anything indicating that tiling is happening during training. Should something become apparent to tell me its working, either at training or inference?

callback = [
  TilerConfigurationCallback(enable=True, tile_size=[128, 64], stride=64),
  ModelCheckpoint(
      mode="max",
      monitor="image_F1Score", # image_F1Score, image_AUROC, pixel_AUROC
  ),
  EarlyStopping(
      monitor="image_F1Score", # image_F1Score, image_AUROC, pixel_AUROC
      mode="max",
      patience=30,
  ),
  MinMaxNormalizationCallback()
]

Hi, tiling is only supported by some models: Padim, Patchcore, Reverse Distillation and STFPM. Refer to the docs for more info.

So in case of EfficientAD tiling is not being applied even if you use the callback. With this in mind, are you sure you are including the callback in the engine initialization, because it should raise an exception since EfficientAD doesn't have tiler object?

Hi, yes the callbacks were passed to the engine constructor but I did not get that warning or error. Is there any technical reason tiling could not be used with the other algorithms, as I understood it was just an abstracted wrapper on top of multiple models? Did i get that wrong? Many thanks

What you probably mean by that is the tiled ensemble, there is quite a lot of confusion between these two.

The basic tiler (what you are using) performs tiling within the model on the features, which are then stacked in batch dimension.
If you want to use the tiled ensemble (the wrapper on top of multiple models), you'll need to use v1.2.0 as it's currently not working in v2.

Refer to v1.2 docs on how to use this tiled ensemble.

Yes the ensemble is exactly what I meant. It did not click with me that there were two tiling methods but that makes sense now. Hopefully it's working in 2.0 soon. Thanks

The tiled ensemble is broken with 2.0 unfortunately. We will try to restore it asap.
