The Maxent algorithm developed for species distribution modelling is a machine learning method, and thus iteratively builds multiple models. It has two main components: 1. Entropy: the model is calibrated to find the distribution that is most spread out, or closest to uniform throughout the study region.

Maximum Entropy Model Similar to logistic regression, the maximum entropy (MaxEnt) model is also a type of log-linear model. The MaxEnt model is more general than logistic regression. It handles multinomial distribution where logistic regression is for binary classification.

MaxEnt can be used to predict probability of presence only by using a transformation of the ROR, called logistic output (Phillips and Dudik 2008), which relies on strong assumptions that have been criticized (section III.

> Hi Folks, We're happy to announce a new version of Maxent (v3. 4.3) is now available for download. This new version fixes various bugs, and now allows users to choose whether to clamp or not using the dismo::predict() function in R. Read more about the bug fixes and download here!

The AUC value close to 1 represented perfect prediction while AUC value of 0.5 or below indicated a bad performance (Wang et al. 2021b). The model performance was divided into five levels by the AUC value: poor (0.5–0.6), fair (0.6–0.7), good (0.7–0.8), very good (0.8–0.9), and excellent (0.9–1.0) (Li et al.

Description of the model. MaxEnt uses the covariate data from the occurrence records and the background sample to estimate the ratio f1(z)/f(z). It does this by making an estimate of f1(z) that is consistent with the occurrence data; many such distributions are possible, but it chooses the one that is closest to f(z).

Maximum entropy (maxent) classifier has been a popular text classifier, by parameterizing the model to achieve maximum categorical entropy, with the constraint that the resulting probability on the training data with the model being equal to the real distribution.
