Paranom: A Parallel Anomaly Dataset Generator

In this paper, we present Paranom, a parallel anomaly dataset generator. We discuss its design and provide brief experimental results demonstrating its usefulness in improving the classification correctness of LSTM-AD, a state-of-the-art anomaly detection model.

AutoPerf: A Generalized Zero-Positive Learning System to Detect Software Performance Anomalies

In this paper, we present AutoPerf, a generalized software performance anomaly detection system. AutoPerf uses autoencoders, an unsupervised learning technique, and hardware performance counters to learn the performance signatures of parallel programs. It then uses this knowledge to identify when newer versions of the program suffer performance penalties, while simultaneously providing root cause analysis to help programmers debug the program's performance. AutoPerf is the first zero-positive learning performance anomaly detector, a system that trains entirely in the negative (non-anomalous) space to learn positive (anomalous) behaviors. We demonstrate AutoPerf's generality against three different types of performance anomalies: (i) true sharing cache contention, (ii) false sharing cache contention, and (iii) NUMA latencies across 15 real world performance anomalies and 7 open source programs. AutoPerf has only 3.7% profiling overhead (on average) and detects more anomalies than the prior state-of-the-art approach.

AI Programmer: Autonomously Creating Software Programs Using Genetic Algorithms

In this paper, we present the first-of-its-kind machine learning (ML) system, called AI Programmer, that can automatically generate full software programs requiring only minimal human guidance. At its core, AI Programmer uses genetic algorithms (GA) coupled with a tightly constrained programming language that minimizes the overhead of its ML search space. Part of AI Programmer's novelty stems from (i) its unique system design, including an embedded, hand-crafted interpreter for efficiency and security and (ii) its augmentation of GAs to include instruction-gene randomization bindings and programming language-specific genome construction and elimination techniques. We provide a detailed examination of AI Programmer's system design, several examples detailing how the system works, and experimental data demonstrating its software generation capabilities and performance using only mainstream CPUs.
