A universal machine learning building block, comprising in some embodiments a differential pair of output electrodes, wherein each electrode comprises a plurality of input lines coupled to it via collections of meta-stable switches. In other embodiments, a methodology can be implemented in the context of hardware and/or software for deriving linear neurons implementing an AHaH plasticity rule and generating an AHaH node(s) that can include one or more such linear neurons, wherein the AHaH node(s) functions according to an AHaH rule. Some embodiments can also include an AHaH classifier and/or AHaH cluster that include one or more such AHaH nodes.
Please help me write a proper abstract based on the patent claims. CLAIM: 1.
