A novel approach for recommendation using optimized bidirectional gated recurrent unit

In today's world, every one of us refreshes our mood and gets energy through entertainment and enjoyment. Human nature is to provide feedback through ratings or comments for products used, services received, or films viewed. The recommendation system serves the user with recommendations based on historical stored information of user preferences. These systems amass information about the user in order to provide personalized experiences. These systems put efforts into delivering personalized experiences by accumulating information about the user. Hybrid algorithms are necessary to address the issues recommendation systems confront, which include low prediction accuracy, output that exceeds range, and inadequate convergence speed. This study suggests building a movie recommendation system using the remora optimization algorithm (ROA) and the bidirectional gated recurrent unit (BiGRU), the most recent version of the recursive neural network (RNN). The proposed method's results are compared with those of the genetic algorithm (GA), feed forward neural network (FFNN), and multimodal deep learning (MMDL). In terms of movie recommendation, BiGRU with ROA performs better than GA, MMDL, and FFNN.
