Contextual Anomaly Detection in Text Data

We propose using side information to further inform anomaly detection algorithms of the semantic context of the text data they are analyzing, thereby considering both divergence from the statistical pattern seen in particular datasets and divergence seen from more general semantic expectations. Computational experiments show that our algorithm performs as expected on data that reflect real-worl...

Anomaly Detection Using System Call Sequence Sets

This paper discusses our research in developing a generalized and systematic method for anomaly detection. The key ideas are to represent normal program behaviour using system call frequencies and to incorporate probabilistic techniques for classification to detect anomalies and intrusions. Using experiments on the sendmail system call data, we demonstrate that concise and accurate classifiers ...

Anomaly Detection and SQL Prepare Data Sets for Data Mining

Anomaly detection has been an important research topic in data mining and machine learning. Many real-world applications such as intrusion or credit card fraud detection require an effective and efficient framework to identify deviated data instances. However, most anomaly detection methods are typically implemented in batch mode, and thus cannot be easily extended to large-scale problems witho...

Text segmentation with character-level text embeddings

Learning word representations has recently seen much success in computational linguistics. However, assuming sequences of word tokens as input to linguistic analysis is often unjustified. For many languages word segmentation is a non-trivial task and naturally occurring text is sometimes a mixture of natural language strings and other character data. We propose to learn text representations dir...

Character-level Recurrent Text Prediction

Text prediction is an application of language models to mobile devices. Currently, the state of the art models use neural networks. Unfortunately, mobile devices are constrainted in both computing power and space and are thus unable to run most (if not all) neural networks. Recently, however, character-level architectures have appeared that have outperformed previous architectures for machine t...
