Gated recurrent units (GRU) based approaches have recently attracted much attention due to their performance in caption generation. Challenges with GRU are to deal with vanishing gradient problems and modulation of the most relevant information flow in deep networks. In this paper, we propose a resnet-based deep GRU approach to overcome the vanishing gradient problem with residual connections while the most relevant information is ensured to flow using multiple layers of GRU. Residual connections are employed between consecutive layers of deep GRU, which improves the gradient flow from lower to upper layers. Experimental investigations on the publicly available MSCOCO dataset prove that the proposed approach achieves comparable performance with some state-of-the-art approaches. Moreover, the approach is embedded into our custom-designed Android application, CaptionEye, which offers the ability to generate captions without an internet connection under a voice user interface.}, number={35}, publisher={Osman SAĞDIÇ}
