TIME: Text and Image Mutual-Translation Adversarial Networks
This addresses the problem of generating realistic images from text descriptions for computer vision and AI applications, offering a novel approach but likely incremental as it builds on existing GAN frameworks.
The paper tackles text-to-image generation by proposing TIME, a lightweight model that jointly learns a generator and discriminator without extra modules or pre-training, achieving state-of-the-art performance with an Inception Score of 4.91 and Fréchet Inception Distance of 14.3 on the CUB dataset.
Focusing on text-to-image (T2I) generation, we propose Text and Image Mutual-Translation Adversarial Networks (TIME), a lightweight but effective model that jointly learns a T2I generator G and an image captioning discriminator D under the Generative Adversarial Network framework. While previous methods tackle the T2I problem as a uni-directional task and use pre-trained language models to enforce the image--text consistency, TIME requires neither extra modules nor pre-training. We show that the performance of G can be boosted substantially by training it jointly with D as a language model. Specifically, we adopt Transformers to model the cross-modal connections between the image features and word embeddings, and design an annealing conditional hinge loss that dynamically balances the adversarial learning. In our experiments, TIME achieves state-of-the-art (SOTA) performance on the CUB and MS-COCO dataset (Inception Score of 4.91 and Fréchet Inception Distance of 14.3 on CUB), and shows promising performance on MS-COCO on image captioning and downstream vision-language tasks.
