An Unsupervised Anomaly Detection Framework for Detecting Anomalies in Real Time through Network System’s Log Files Analysis
<p>Nowadays, in almost every computer system, log files are used to keep records of occurring events. Those log files are then used for analyzing and debugging system failures. Due to this important utility, researchers have worked on finding fast and efficient ways to detect anomalies in a …

Log file anomaly detection using knowledge graphs and graph neural networks
Log files contain valuable information for detecting abnormal behavior. To detect anomalies, researchers have proposed representing log files as knowledge graphs (KGs) and using KG completion (KGC) techniques to predict new facts. However, current research in this area is limited, and there is no …

Predicting Hard Drive Failures in Computer Clusters
… proach to predict failure events based on system log files. These files contain mes- sages that represent a change of system state. While a single message in the file may not be sufficient for predicting failure, a sequence or pattern of messages may be. This approach uses a sliding window …

Generating Log File Analyzers
… Programs often store some of their outputs in files known as log files. The task of evaluating test results can be automated by using a log file analyzer. The main goal of this thesis is to design an approach to generate log file analyzers based on a set of state machine specifications. Our …

Advanced Statistical Process Control Techniques for Analysis of Medical Linear Accelerator Performance
Statistical Process Control (SPC) is an approach to measure normal and abnormal variations of a process. Its success rests upon the fact that any process can be mapped by a series of inputs and outputs. SPC techniques are displayed using process behavior charts which are graphs that contain data …

Quantifying The Magnitude of to tal Dose Deviation Caused By Various Sources of Error Among Iroc Phantom Irradiation Results
<p>The Imaging and Radiation Oncology Core (IROC) phantoms are used as an end-to-end test of an institution’s radiotherapy processes, and for clinical trial credentialing. Phantoms are treated like patients, and evaluation of the doses received by the thermoluminescent dosimeters (TLDs) inside the …
