Abstract: A computer-implemented method, a computer program product, and a computer system for accelerated learning. A computer partitions an independent variable of input data into partitions. A computer creates data samples in each of the partitions, where each of the data samples has less granularity. For each of the partitions, a computer trains a machine learning model independently on each of the data samples and compares results of training on the data samples. For each of one or more partitions in which results of training on a predetermined number of the data samples are statistically identical at a predetermined confidence level, a computer outputs a result of training on one of the data samples. For each of one or more rest partitions in which no result of training has been outputted, a computer merges each pair of the data samples and uses merged data samples to train the machine learning model.
