Support Vector Machines on Big Five Traits and Politics
This is an example of Support Vector Machines, using one of my usual data sets, as part of a Pluralsight training presentation, Data Mining Algorithms in SSAS, Excel, and R . In terms of results, the prediction primarily predicts voter leanings based on two (2) traits, openness and conscientiousness, and although using all five (5) factors improved the prediction quality, plotting that is problematic. For this, the model is 96% predictive of Republican outcomes, but only 66% accurate in predicting Democratic leaning.
