Pattern Discovery and Disentanglement (PDD) AI software for deep knowledge discovery from relational data

Description of the invention

University of Waterloo (UW) researchers have developed novel PDD (Pattern Discovery and Disentanglement) software to discover deep knowledge inherent in relational and array data for various applications. PDD uses novel autonomous and scalable algorithms to disentangle and discover deep knowledge to reveal subtle functionality and relations and uses the knowledge discovered to enhance machine learning, achieving much better prediction results with explanation. The software also solves imbalanced class, biases, anomaly and outliers problems that have plagued ML for decades.

Advantages

The invention provides:

• Time/Cost Reduction – prediction based only on data with no reliance on explicit prior knowledge.
• Higher accuracy - leveraging rare cases and mislabeling
• Robust to data noise, biases and imbalanced classes
• Flexible - can be applied to a wide range of scenarios
• Explainable –providing explicit patterns/pattern clusters for further exploration, experts’ understanding and knowledge organization.

Potential applications

• Unsupervised classification/tagging of data in relational datasets – as an example, if a tabulated record associated with heart disease (Figure.1) is inputted to PDD software, the output can include:
• Automatic labeling and grouping of patients with explanation
• Identification of correlated indicants for each group
• Identification of Rare Cases and the patterns they possess
• Detection of early stage of the disease in patients
• Prediction of “Healthy” and “Sick” patients and identification of mislabeled, biased cases and outliers.
• Other sectors where relational tables are used, e.g. Finance, Banking, Insurance, Logistics, Manufacturing and Cybersecurity
