Description:
Regression ensemble of sensillum SBT-I-B with 2 individual models (I1 and I12) used for prediction of spike amplitude of the extracellularly record of ORN response potentials of the antennal trichoid sensilla to Cx quinquefasciatus repellents.

The training was performed with the Bagging algorithm and Linear Regression as classifier as default in Weka 3.9.4 with a 10-fold cross-validation. Models I1 and I12 were developed by using 6 and 7 QuBiLS-MIDAS descriptors, respectively, namely:

Training set:
50 compounds extracted from the Liu, et al., 2013 original experimental research constitute the training set 10.1016/j.jinsphys.2013.08.016

Performance:
For a 10-fold cross-validation, the statistical parameters (performance without applicability domain) are R = 0.9888, MAE = 2.1584, RMSE = 3.8935, RAE = 13.8826 %, and RRSE = 14.6479 %.

Classification Breakpoint:
The breakpoint for sensillum SBT-I-B is 16.3 spikes/s. Values greater than or equal to the breakpoint will elicit a response in this specific sensillum. Lower values represent certain actions occurring, however, they are not enough to activate the sensillum response.
