US Patent 11775831: Cascaded Computing for Convolutional Neural Networks

• Title: Cascaded computing for convolutional neural networks
• Assignee: Skysong Innovations LLC
• Inventors: Jae-sun Seo, Minkyu Kim
• Filing Date: January 13, 2023
• Issue Date: October 3, 2023
• Abstract: The patent describes techniques for efficiently reducing the total computation in Convolutional Neural Networks (CNNs) without affecting output or classification accuracy. This is achieved by reducing computation redundancy, specifically in convolution and pooling operations. The method involves dividing input features into groups of precision values and cascading operations. A maximum value is identified (with high probability, e.g., 90%) using a small number of most significant bits (MSBs) from the input features. Full-precision convolution is then performed only on the input exhibiting this maximum, thereby reducing the total number of bits used for convolution while maintaining accuracy.

Plain-Language Overview of Independent Claim(s):

• Independent Claim 1: This claim covers a system (specifically, non-transitory computer-readable storage media storing instructions for a processor) that processes data within a Convolutional Neural Network (CNN). The system performs an initial, low-precision calculation for multiple data sets using only their most significant bits (MSBs). It then examines these initial results to determine if a clear maximum value is present among them. If a maximum is identified, the system performs a full, high-precision calculation only for the specific data set that showed the maximum value. Finally, this full-precision result is passed on to the next layer of the CNN.

Litigation Information:
The patent family is involved in litigation. As of the current date, the following cases are noted:

• A PTAB case, IPR2025-01399, was filed but not instituted procedurally.
• A US case was filed in the Texas Western District Court (case number 7:25-cv-00040).
• Another US case was filed in the Texas Eastern District Court (case number 2:25-cv-00098).
• The first worldwide family litigation has also been filed.
