 Cats continue to play an essential role in everything significant in machine learning. Self-supervised research [“Unsupervised Visual Representation Learning by Context Prediction” [1]](https://arxiv.org/abs/1505.05192) predicts the positional location of one rectangular section of an image relative to another by using spatial context as a supervisory signal for training a rich visual representation. For instance, the right ear of a cat would be in the top-right position relative to the eyes of a cat. This approach allows learning about cats, dogs, or buses without prior explicit semantic labeling.

 NLP models such as [BERT [8]](https://arxiv.org/abs/1810.04805) and [GPT [9]]((https://s3-us-west-2.amazonaws.com/openai-assets/research-covers/language-unsupervised/language_understanding_paper.pdf)) uses the self-supervised method for pretraining. For example, the BERT method randomly chooses 15% of words in the corpus, converts those words to [MASK] token, and train the model to predict the word that is obscured by the [MASK] token.
