AI Definitions: Test-time training

Test-time training (TTT) - An alternative to transformers (which have high energy demands), TTTs theoretically do not grow when processing additional data, as transformers do. TTTs encode the data into representations called weights, so that additional data does not increase the size of the model. In effect, it is nestling a neural network inside another neural network. This type of machine learning model is in its early development stages and is only now being tested.
