Deep learning for embedded vision requires large datasets. Indeed, the more varied the training data is, the more accurate the resultant trained network tends to also be. But, acquiring and accurately annotating datasets costs time and money. This talk shows how to get more out of existing datasets. First, state-of-art data augmentation techniques are reviewed, and a new approach, smart augmentation, is explained. Next, GANs (generative adversarial networks) that learn the structure of an existing dataset are explained; several example use cases (such as creating a very large dataset of facial training data) show how GANs can generate new data corresponding to the original dataset. But building a dataset does not by itself represent the entirety of the challenge; data must also be annotated in a way that is meaningful for the training process. The presentation then gives an example of training a GAN from a dataset that incorporates annotations. This technique enables the generation of pre-annotated data" providing an exciting way to create large datasets at significantly reduced costs.
