Abstract

In this paper, we address the task of learning novel visual concepts, and their interactions with other concepts, from a few images with sentence descriptions.

Using linguistic context and visual features, our method is able to efficiently hypothesize the semantic meaning of new words and add them to its word dictionary so that they can be used to describe images which contain these novel concepts.

Our method has an image captioning module based on m-RNN with several improvements.

In particular, we propose a transposed weight sharing scheme, which not only improves performance on image captioning, but also makes the model more suitable for the novel concept learning task.

We propose methods to prevent overfitting the new concepts.

In addition, three novel concept datasets are constructed for this new task, and are publicly available on the project page.

In the experiments, we show that our method effectively learns novel visual concepts from a few examples without disturbing the previously learned concepts.
