Computer model calibration is a formal statistical procedure to infer input parameters by combining information from model runs and observational data. One of the most important aspects of DeepDive is its iterative workflow. The calibration process is explained by a flowchart given below. Deep neural network (DNN) classifiers are often overconfident, producing miscalibrated class probabilities. As in other machine learning (ML) problems, trees are also used for calibration, the standard algorithm builds a superposition of a tree based on the initial features and logistic regressions (each in its own leaf) over the estimates of the algorithm: Build a decision tree (not very deep) based on the initial features. Here, for simplicity, we use H(x t) to denote order to overcome the coupling effects, which is a chronic. on probability calibration shows that research on classification calibration under class imbalance in the context of deep learning is so far lacking in the scientific literature.
