A multimodal deep learning architecture for smoking detection with a small data approach

Introduction Covert tobacco advertisements often raise regulatory measures. This paper presents that artificial intelligence, particularly deep learning, has great potential for detecting hidden advertising and allows unbiased, reproducible, and fair quantification of tobacco-related media content. Methods We propose an integrated text and image processing model based on deep learning, generative methods, and human reinforcement, which can detect smoking cases in both textual and visual formats, even with little available training data. Results Our model can achieve 74% accuracy for images and 98% for text. Further-more, our system integrates the possibility of expert intervention in the form of human reinforcement. Conclusions Using the pre-trained multimodal, image, and text processing models available through deep learning makes it possible to detect smoking in different media even with few training data.
