New convolutional framework boosts recommendation system efficiency

Researchers have developed a new framework called NextConvRec for session-based recommendation systems, which aims to improve efficiency and performance by utilizing pure convolutional methods instead of attention-based transformers. This framework incorporates a Structural and Positional Convolutional Encoder (SPCE) that combines learnable convolutional positional biases with graph convolutional network (GCN) layers to capture session-level structural signals. Experiments on four benchmark datasets demonstrated that NextConvRec outperforms existing state-of-the-art baselines by an average of 1.73% and reduces inference time per session by 16.7%, suggesting that convolutional architectures are a viable path for effective and efficient session-based recommendations.
