A configurable, data-driven computer software program that predicts system behavior and detects anomalies within these behavior predictions. The software program is configured by a data set specified by the user or another computer program and utilizes system data provided by the user or the target system itself. The program predicts system behavior, estimates outlying predictions and then automatically labels the predictions and outliers. Once system predictions are labeled, the program uses outlier recognition to classify predictions as expected (nominal) or unexpected (anomalous) behavior. Users can configure the program to perform various tasks, such as testing other software programs for defects, as well as detecting and mitigating system errors / faults in real-time on target systems.

Provided is a time interleaving circuit to mitigate glitches. A first loading stage outputs first data representative of first serialized data. A second loading stage generates second serialized data. The second loading stage receives the first data output by the first loading stage. In response to the first data having a first state, the time interleaving circuit inverts the second serialized data to generate second data representative of the second serialized data. In response to the first data having a second state, the time interleaving circuit outputting the second data without inverting the second serialized data. Exclusive disjunction logic receives the second data and operates on the first data and the second data to generate output data.

Message faulting is the leading cause of poor reception. Currently, most faulting in 5G and 6G requires either transmission of bulky FEC bits, or retransmission of the message, at substantial delay and cost. This paper shows how the receiver can internally (autonomously) correct the message faults by scanning the digitized waveform signals, to detect characteristic fault signatures that clearly identify the likely faulted subcarriers. With that information, and the CRC or other appended code, and optionally an AI assist, the receiver can correct the message in a fraction of the time required for a retransmission. The message is corrected instantly, with zero background generation, zero bandwidth consumption, and zero cost. Autonomous fault mitigation in the receiver is the most efficient way to improve user reception.
