CNN-GRU: Transforming image into sentence using GRU and attention mechanism
(Grenze Scientific Society, 2021) Saini, G.; Patil, N.
Recent advancement of the deep neural network has triggered great attention in both Natural Language Processing (NLP) and Computer Vision (CV). It provides an efficient way of understanding semantic and syntactic structure which can deal with complex task such as automatic image captioning. Image captioning methodology mainly based on the encoder-decoder approach. In the present work, we developed a CNN-GRU model using Convolutional Neural Network (CNN), Gated Recurrent Unit (GRU) and attention mechanism. Here VGG16 is used as an encoder, GRU and attention mechanism are used as a decoder. Our model has shown significant improvement compared to other state-of-art encoder-decoder models on the famous MSCOCO data set. Further, the time taken to train and test our model is two-third as compared to other similar models such as CNN-CNN and CNN-RNN. Â© Grenze Scientific Society, 2021.
