WiMi Hologram Cloud Inc. has developed a deep learning-based multi-modal video recommendation system that uses advanced algorithms and multi-modal data analysis to provide users with personalized video recommendation services. The core of the system is a deep learning algorithm that is capable of extracting rich hidden features from video data and generating accurate recommendations based on the user’s personal preferences. The technology adopts a convolutional neural network (CNN) as the main algorithm for feature extraction, which contains three main parts: convolutional layer, pooling layer and fully connected layer.
