Abstract

Joint understanding of video and language is an active research area with many applications. Prior work in this domain typically relies on learning text-video embeddings. One difficulty with this approach, however, is the lack of large-scale annotated video-caption datasets for training. To address this issue, we aim at learning text-video embeddings from heterogeneous data sources. To this end, we propose a Mixture-of-Embedding-Experts (MEE) model with ability to handle missing input modalities during training. As a result, our framework can learn improved text-video embeddings simultaneously from image and video datasets. We also show the generalization of MEE to other input modalities such as face descriptors. We evaluate our method on the task of video retrieval and report results for the MPII Movie Description and MSR-VTT datasets. The proposed MEE model demonstrates significant improvements and outperforms previously reported methods on both text-to-video and video-to-text retrieval tasks.

Retrieval web-demo

MEE Text-to-Video Search Engine is Text-to-Video web demo search engine based on our proposed Mixture-of-Embedding-Experts (MEE) model. The model was trained on the MPII movie training set and it is tested on both MPII validation and test set and the MSR-VTT dataset. Our web demo runs in real time on a CPU based machine.
