MaxWiK - Machine Learning Method Based on Isolation Kernel Mean Embedding
Incorporates Approximate Bayesian Computation to get a
posterior distribution and to select a model optimal parameter
for an observation point. Additionally, the meta-sampling
heuristic algorithm is realized for parameter estimation, which
requires no model runs and is dimension-independent. A sampling
scheme is also presented that allows model runs and uses the
meta-sampling for point generation. A predictor is realized as
the meta-sampling for the model output. All the algorithms
leverage a machine learning method utilizing the maxima
weighted Isolation Kernel approach, or 'MaxWiK'. The method
involves transforming raw data to a Hilbert space (mapping) and
measuring the similarity between simulated points and the
maxima weighted Isolation Kernel mapping corresponding to the
observation point. Comprehensive details of the methodology can
