Welcome to AIPSE

We are team of process systems engineers making world with AI

Get Started

Few Words About Us

Up to date, either mechanistic model (i.e., white box) or data-driven model (i.e., black box) has been playing a primary role in Process Systems Engineering. Now, we plan to integrate both of them via hybrid modeling in order to achieve the next generation Process Systems Engineering world based on AI.

Mechanistic Model

This is also known as first-principles or mathematical model, depending on specific equations and constraints.

Data-driven Model

Machine learning and deep-learning can be employed because we have data available.

Hybrid Model

In combination of white box and black box, the resulting gray box will be able to give us a better understanding.
