WebThere are two main advantages of unfolding over unrolling: (1) Analytical differentiation of U allows for removal of the inner loops of unrolling, greatly reducing the total number of unrolled operations as depicted in Figure 1, which shows forward pass steps in red with their corresponding backward passes in blue. WebThese improvements to coverage and skills helped protect customers through around-the-clock vigilance. Workflows, an enhanced log and case management system matured the SOC further. Automation and migration to a cloud-native platform further optimized the SOC, which helped to properly store information and inform future decision making.
