A COMPUTER-IMPLEMENTED METHOD FOR OPTIMIZING A NEURAL NETWORK MODEL FOR 3D OBJECT DETECTION

Absstract of: WO2026127827A1

A computer-implemented method for optimizing a neural network model for three-dimensional (3D) object detection. The method comprises receiving a pretrained 3D object detection model with multiple neural network layers and computes a layer-wise sparsity allocation across the detection model based on a predefined computational constraint. The layer-wise sparsity allocation is transformed into a layer-wise pruning ratio for each layer using second-order Hessian-based rate-distortion analysis, where the pruning ratio minimizes distortion in detection outputs. The computed pruning ratios are applied to remove redundant weights from each layer of the model, producing a pruned, pretrained 3D object detection model. This method reduces computational complexity while maintaining detection accuracy, making it suitable for real-time 3D perception applications.
