In this work, we present the Text Conditioned Auxiliary Classifier Generative
Adversarial Network, (TAC-GAN) a text to image Generative Adversarial Network
(GAN) for synthesizing images from their text descriptions. Former approaches
have tried to condition the generative process on the textual data; but allying
it to the usage of class information, known to diversify the generated samples
and improve their structural coherence, has not been explored. We trained the
presented TAC-GAN model on the Oxford-102 dataset of flowers, and evaluated the
discriminability of the generated images with Inception-Score, as well as their
diversity using the Multi-Scale Structural Similarity Index (MS-SSIM). Our
approach outperforms the state-of-the-art models, i.e., its inception score is
3.45, corresponding to a relative increase of 7.8% compared to the recently
introduced StackGan. A comparison of the mean MS-SSIM scores of the training
and generated samples per class shows that our approach is able to generate
highly diverse images with an average MS-SSIM of 0.14 over all generated
classes.

本研究提出了 “TAC-GAN” 模型，一种文本到图像的生成对抗网络；相较于以前的方法，该模型使用类信息，能够提高生成样本的多样性并改善其结构一致性，对 Oxford-102 的花卉数据进行训练并通过 Inception-Score 和 MS-SSIM 测评其性能，结果表明其性能超越现有的同类模型，其平均 MS-SSIM 值达到 0.14。
