A method for retrospective calibration of a glucose sensor uses stored values of measured working electrode current (Isig) to calculate a final sensor glucose (SG) value retrospectively. The Isig values may be preprocessed, discrete wavelet decomposition applied. At least one machine learning model, such as, e.g., Genetic Programming (GP) and Regression Decision Tree (DT), may be used to calculate SG values based on the Isig values and the discrete wavelet decomposition. Other inputs may include, e.g., counter electrode voltage (Vcntr) and Electrochemical Impedance Spectroscopy (EIS) data.

An XML-based symbolic computer language, interpreter, and corresponding execution environments are disclosed. The XML-based symbolic computer language, called “OLIN” (One Language Intelligent Network) enables a computer program to be written as an XML-compliant document. OLIN programs are interpreted by an interpreter by parsing the XML content to extract symbolic expressions embedded therein, and evaluating those symbolic expressions. The XML-based symbolic computer language is object-oriented and is based on inherent principles of the LISP programming language. Accordingly, code and data are treated the same. The language provides built-in structures and functions for implementing neural networks and genetic programming. OLIN programs may be executed by a single computer, or via a multiprocessing environment, including distributing processing environments and multiprocessor computers.
