PNN Analytics is a second-generation intelligent self-organized neural network software system developed in 2016 by PNN Technologies Inc, currently it is patent pending. PNN Analytics is designed for analyzing Big Data and providing insight into data structures and hidden patterns. The software is written in Apache Spark on cloud platforms, which is the state-of-the-art cluster computing framework. PNN Analytics is a universal learning inference machine, a single architecture handling all kinds of analytics problems; multi-resolution clustering, classification/prediction, pattern recognition, user recommendation, information retrieval, risk analysis, and decision support. Furthermore it is a self-organizing expert system, where inference rules can be extrapolated and clearly seen through input and output queries.
