Publication number: 20230401422Abstract: A full-stack neural network obfuscation framework obfuscates a neural network architecture while preserving its functionality with very limited performance overhead. The framework includes obfuscating parameters or “knobs”, including layer branching, layer widening, selective fusion and schedule pruning, that increase the number of operators, reduce/increase the latency, and number of cache and DRAM accesses. In addition, a genetic algorithm-based approach is adopted to orchestrate the combination of obfuscating knobs to achieve the best obfuscating effect on the layer sequence and dimension parameters so that the architecture information cannot be successfully extracted.Type: ApplicationFiled: June 9, 2023Publication date: December 14, 2023Applicant: Arizona Board of Regents on behalf of Arizona State UniversityInventors: Jingtao Li, Chaitali Chakrabarti, Deliang Fan, Adnan Siraj Rakin

Publication number: 20230078473Abstract: A robust and accurate binary neural network, referred to as RA-BNN, is provided to simultaneously defend against adversarial noise injection and improve accuracy. Recently developed adversarial weight attack, a.k.a. bit-flip attack (BFA), has shown enormous success in compromising deep neural network (DNN) performance with an extremely small amount of model parameter perturbation. To defend against this threat, embodiments of RA-BNN adopt a complete binary neural network (BNN) to significantly improve DNN model robustness (defined as the number of bit-flips required to degrade the accuracy to as low as a random guess). To improve clean inference accuracy, a novel and efficient two-stage network growing method is proposed and referred to as early growth. Early growth selectively grows the channel size of each BNN layer based on channel-wise binary masks training with Gumbel-Sigmoid function.Type: ApplicationFiled: September 14, 2022Publication date: March 16, 2023Applicant: Arizona Board of Regents on behalf of Arizona State UniversityInventors: Deliang Fan, Adnan Siraj Rakin, Li Yang, Chaitali Chakrabarti, Yu Cao, Jae-sun Seo, Jingtao Li

Publication number: 20220374263Abstract: Embodiments relate to diagnosis and recovery of cloud based systems. From an incident ticket, a dynamic diagnostics graph is generated visualizing a hierarchy (ancestor, child) of diagnostic jobs investigating the functioning cloud system. By indicating and checking job statuses, child jobs dependent on a skipped or failed job can be skipped according to a dynamic pruning technique—thereby trimming an entire branch. And, by running separate groups of diagnostic jobs in parallel across different nodes, the diagnostic process can be finished rapidly and efficiently. A diagnostic report includes the dynamic diagnostics graph. For system recovery, the dynamic diagnostic graph is analyzed to automatically provide one or more appropriate Recommended Actions (RAs) resolving cloud system problem(s) revealed by diagnostic efforts. Those appropriate RAs may be provided by performing machine learning (e.g., referencing a neural network) with a model trained from historical cloud diagnostic and recovery activity.Type: ApplicationFiled: May 18, 2021Publication date: November 24, 2022Inventors: Rui Ban, Bowen Ren, Yucheng Guo, Jingyuan Li, Jingtao Li, Wenbin Zhao, Yan Ke, Li-Ping Sun
