Natural Language Processing with Optimal Deep Learning-Enabled Intelligent Image Captioning System

The recent developments in Multimedia Internet of Things (MIoT) devices, empowered with Natural Language Processing (NLP) model, seem to be a promising future of smart devices. It plays an important role in industrial models such as speech understanding, emotion detection, home automation, and so on. If an image needs to be captioned, then the objects in that image, its actions and connections, and any silent feature that remains under-projected or missing from the images should be identified. The aim of the image captioning process is to generate a caption for image. In next step, the image should be provided with one of the most significant and detailed descriptions that is syntactically as well as semantically correct. In this scenario, computer vision model is used to identify the objects and NLP approaches are followed to describe the image. The current study develops a Natural Language Processing with Optimal Deep Learning Enabled Intelligent Image Captioning System (NLPODL-IICS). The aim of the presented NLPODL-IICS model is to produce a proper description for input image. To attain this, the proposed NLPODL-IICS follows two stages such as encoding and decoding processes. Initially, at the encoding side, the proposed NLPODL-IICS model makes use of Hunger Games Search (HGS) with Neural Search Architecture Network (NASNet) model. This model represents the input data appropriately by inserting it into a predefined length vector. Besides, during decoding phase, Chimp Optimization Algorithm (COA) with deeper Long Short Term Memory (LSTM) approach is followed to concatenate the description sentences produced by the method. The application of HGS and COA algorithms helps in accomplishing proper parameter tuning for NASNet and LSTM models respectively. The proposed NLPODL-IICS model was experimentally validated with the help of two benchmark datasets. A widespread comparative analysis confirmed the superior performance of NLPODL-IICS model over other models.
