Welcome to the second issue of IEEE Transactions on Computational Social Systems (TCSS) in 2022. In this issue, we are going present 25 regular articles. After “scanning issue,” I would like share some my opinions and perspectives fundamentals computational psychophysiology: theory methodology.

The connection matrix is a powerful algebraic topological tool from Conley index theory, subfield of dynamics. theory purely generalization Morse in which the subsumes role boundary operator. Over last few decades, Conley’s approach to dynamics has been cast into computational form. In this paper we introduce and categorical framework for theory. Broadly speaking, contribution promotes computat...

MCG, the Multifunction Cardiogram, is a revolutionary approach to diagnosing cardiac conditions. It goes beyond a traditional ECG by incorporating aspects of computational biology and systems theory to build a functional mathematical model of the cardiac system – the heart, blood and circulatory system – from which a more accurate diagnosis can be drawn. This white paper discusses the theoretic...

This introductory lecture will be concerned with polynomial invariants of finite groups which come from a linear group action. We will introduce the basic notions of invariant theory, discuss the structural properties of invariant rings, comment on computational aspects, and finally present two applications from function theory and number theory.
