PNN Solution is a first-generation intelligent self-organizing neural network software developed and patented in 2007 by PNN Technologies Inc. PNN Solution can be used to solve many different kinds of inference problems, such as clustering, pattern recognition, and prediction. PNN Solution has also been customized for bioinformatics applications.

Developed in 2016 by PNN Technologies Inc., PNN Analytics is a second-generation, self-organizing neural network and universal inference engine. Its unified architecture supports multi-resolution clustering, classification, prediction, pattern recognition, risk analysis, and decision support. It also functions as an expert system that derives inference rules from input–output queries.

PNN AI is a third-generation self-organized deep learning neural network. It is an ongoing project in artificial general intelligence and is currently patent-pending. PNN AI model matches the spiking neural network (SNN) architecture. It can be implemented using neuromorphic circuits, especially a memristor-based in-memory computing machine.
