WebNov 19, 2024 · Time series classification (TSC) task is one of the most significant topics in data mining. Among all methods for this issue, the deep-learning-based shows superior performance for its good adaption to raw series data and automatic extraction of features.

If the first CPU of a package comes online, it is necessary to test whether. the TSC is in sync with a CPU on some other package. When a deviation is. observed (time going backwards between the two CPUs) the TSC is marked.
