Small datasets refer to collections of data that are limited in size, often containing insufficient examples for effective training of deep learning models. These datasets can lead to challenges such as overfitting, where a model learns the noise in the training data instead of general patterns. In contexts like transfer learning and fine-tuning with pre-trained CNNs, small datasets can be particularly beneficial because they allow for the leveraging of pre-existing knowledge from larger datasets, enabling models to perform well despite having limited specific data.
congrats on reading the definition of small datasets. now let's actually learn it.
