MNTN: Deep Modular N-shape Transformer Networks for Image Captioning

Inhalt:
Image captioning requires the computer automatically generate natural language captions from the input image. Recent progress on image captioning uses multiple features as model inputs to improve performance. Nevertheless, there has not been sufficient feature utilization. In this paper, we introduce a Modular N-shape Transformer (MNT) fully to the high order intra interaction of single-feature and the high order guided interaction of multi-feature, which is composed of two basic attention transformer units. Furthermore, we present a deep Modular N-shape Transformer Network (MNTN) that novelty integrates MNT into image encoder part of image captioning model not only fully to leverage the spatial and location information of image, but also make the features better locate the image. Experiments show that MNTN outperforms most previously published methods and can express the semantic content of the image extreme accurately.
