An electrocardiogram (ECG) represents the electrical activity of the heart and can be used to investigate cardiac health. Routinely, subtle changes in the ECG’s P-QRS-T wave are employed to depict a particular type of cardiac abnormality. Herein, we have used heart rate (derived from ECG) as the base signal for our analysis, to demonstrate how effectively we can differentiate cardiac

Mathematics is about knowing. Mathematical knowledge is a record of knowing just as
sentences, besides being descriptions of the things to which they refer to, exemplify
rules of composition. The functorial calculus of acquiring mathematical knowledge
resembles cognition, which involves physical stimuli, neural sensations, mental
concepts, and conscious experience. Herein we build, on the foundational similarity
between cognition and mathematics, a model of cognition. Using category theory we
explicated the functorial calculus of going from given particulars to measurements of
the given particulars, to conceptualization of the particulars based on their measured
properties, to interpretations of the thus formed theories, and resulting in knowledge.
This simple model system can be used to systematically address fundamental
questions of cognitive science such as 'how do we know?' More immediately, our
results argue against the contemporary compartmentalization of scientific knowledge
and ordinary cognition.
