Introduction The discovery of place cells and grid cells underscored the importance of the hippocampal formation as a key neural substrate for spatial navigation1,2, fueling an intensive investigation of this brain region. Understanding spatial coding requires a model of the information flow in the un...
peregrinus damage and significant indices were chosen based on variable importance scores (VIP) and were then entered into a PLS model. The indices chosen by VIP predicted T. peregrinus damage with a mean bootstrapped R-2 value of 0.71 on an independent test dataset. A greedy backward variable...
To prescreen relative value signals in the activity of mOFC neurons without normalization equations, we first determined whether mOFC neurons signal relative value by using a variable selection approach. Neuronal discharge rates (F) were fitted by a linear combination of the following variables: ...
These were equations in which the left-hand side of the equality took the form dx/dt, the rate at which the dependent variable x is changing with respect to time t, the independent variable. In other words, because a lumped model had been adopted, one only had to consider variation of ...
An essential requirement for the PLS-DA model is to calculate the variable importance in the projection (VIP) score of each variable (i.e., VIs in this study). The VIP score serves as a measure of the contributions of input variables to the classification results [41]. The VIP score is...
In this case, we can use a sample x̃ = (x1, … , xt) from the random variable X to estimate the unknown impact score F( ) by means of the Bayes estimate F∗ , which minimises the Bayes risk. This involves minimising IE [L(F( ), )] , where the expectation is taken ...
With regard to a single-response system, the significance of input variables is obtained, as shown in Table 1. The significance of theith input variable is denoted bysi. If one wishes to selectn∗n∗<nsignificant input variables, they may selectn∗input variables in descending order of ...
We have explained the PLS model descriptors according to their maximum to minimum contributions (significance level) towards the response values (logKow and logKoc) based on their VIP (variable importance plot) (Akarachantachote et al., 2014) and loading plots (Ojha and Roy, 2018). In the...
