Masked Autoencoder, SSL debug utilities

Masked Autoencoders

We implemented the paper Masked Autoencoders Are Scalable Vision Learners. https://arxiv.org/abs/2111.06377 is suggesting that a masked auto-encoder (similar to pre-training on NLP) works very well as a pretext task for self-supervised learning. See #721 for more details. Thanks to @Atharva-Phatak for helping us figure out a good implementation method.

Collapse detection helper for SimSiam

We added a helper for detecting a collapsing SimSiam network. See https://ar5iv.labs.arxiv.org/html/2011.10566#S4.SS1 for more details.

Plot positive and negative example images

We added a helper to plot positive and negative example images, which also allows seeing what the augmentations do. See #818 for more details.

Video Dataset initialisation improvements

Video Dataset initialisation speedup

When initialising a LightlyDataset on a directory with videos, all frames in all videos have to be counted to know the number of frames in the dataset and their filenames. This process now uses multihreading over videos and can thus be much faster.

Video Dataset initialisation bugfix

We fixed a bug that the number of frames was estimated wrongly based on the length of the video when using the pyav backend.

Video Dataset initialisation progress bar

When initialising the video dataset, a progress bar over the videos is shown. This is helpful information for datasets with many videos.

Decoupled Contrastive Learning, Model heads with default parameters

Decoupled Contrastive Learning

We have implemented the Decoupled Contrastive Learning (DCL) loss. It allows faster training with smaller batch sizes than other self-supervised learning models.

Documentation: https://docs.lightly.ai/examples/dcl.html
Decoupled Contrastive Learning paper: https://arxiv.org/abs/2110.06848

Model heads with default parameters

All model heads have now default parameters following the values of the original papers.

Create custom metadata config

Custom metadata in the Lightly Platform can now easily be configured via ApiWorkflowClient.create_custom_metadata_config()

Progress bar for video dataset initialization

Constructing a LightlyDataset with large video datasets can take long, as all frames in all videos have to be counted. We added a tqdm progress bar for it.
