• biological research - describe logic of neural tissue types
• create aWee dynamical model
• setup running aWee model, define runtime metrics to measure proof of the concept

Overall Features

• to be refined later

Mocked Functions

• M-01. aMatter has primitive predefined set of effectors producing representation in external world based on predefined set of low-level commands provided by hardcoded motor strategies
• M-02. aMatter limits effectors actions to ones explaining internal representations by means of hardcoded symbolical language
• M-03. aMatter has primitive predefined hierarchy of behavioural strategies, on leaf level directly connected with effectors commands

Cognition

• C-01. aMatter receives information using predefined set of sensors
• C-02. aMatter recognises received information in real-time mode and calculates recognition metric R reflecting percentage of successfully recognised sensors inputs in given environment
• C-03. aMatter generalises unrecognised inputs so that R monotonously increases for the same static environment
• C-04. aMatter forms growing set of internal entities, so that specific subset of internal entities, when being in active state, can be treated as a representation of specific external data from sensors, disregarding whether previously perceived or internally inspired
• C-05. aMatter is able to forget internal entities, if not activated for a long time, so that the same input triggers another set of internal entities after a while
• C-06. aMatter forms growing set of associations between internal entities activated about the same time

Feeling

• F-01. aMatter collects information from predefined set of embodiment signals equivalent in purpose with human being, with body treated as related operating system process with all its inherent features and properties
• F-02. aMatter collects predefined set of uncertainty metrics from expectation flow of behavioural strategies
