Five ML algorithms including K-nearest neighbor (KNN), logistic regression, Nave Bayes, decision tree, and random forest are considered for classification tasks. Experimental results tested on eleven benchmark datasets from UCI ML repository show that the proposed HBCRO-BPSO algorithm improves the ...

The basic idea of the SMOTE algorithm is to analyse the minority class samples, and based on them, manually synthesise new samples to add to the dataset17. SMOTE, as an undersampling method, balances the proportion of sample classes in the dataset to some extent by increasing the number of...
Algorithm Theoretical Basis Document (ATBD) General Documentation MOD14A1 V6数据集提供了从MODIS 4米和11米辐射值得出的1公里分辨率的每日火灾掩码组合。火灾探测策略是基于对火灾的绝对探测(当火灾强度足以探测时),以及相对于其背景的探测(考虑到表面温度的变化和太阳光的反射)。该产品区分了火灾、无火灾和无观测。
As a result, the core of the C2 architecture is a ‘messaging bus’ which allows for any microservice, log, user or algorithm to be informed of events across the system as they occur, such as an ALR1500 connecting by satellite to upload data or download a mission. This structure scales...
(PSO-BP) algorithm to unify the scale of DMSP/OLS and NPP/VIIRS images. The initial parameters of the PSO-BP algorithm (i.e., C1 and C2 values were both set to 2.0, and the structure of the model included one hidden layer with five nodes; the maximum iteration number and population ...
In order to calculate SMAP/CYGNSS soil moisture, we first derived CYGNSS reflectivity, then used the SMAP/CYGNSS brightness temperature algorithm to downscale SMAP brightness temperatures to 3 km [23], and then calculated soil moisture using the SMAP single-channel vertically polarized algorithm (SCA...
The random forest model is an extended machine learning algorithm of bagging (bootstrap aggregation) that not only builds a number of decision trees on bootstrapped training samples, but also randomly selects a subset of predictors (mtry) from the full set of predictors when building these trees...
The first paper (Agrawal & Srikant, 2000) takes the approach of randomizing the data through the injection of noise, and then recovers from it by applying a reconstruction algorithm before a learning task (the induction of a decision tree) is carried out on the reconstructed dataset. The ...
