<p>First, we chose the best feature which had the highest correlation to the label. </p>
<p>Attached here a correlation heatmap showing the correlation between the features to each of the labels. It can be seen from the heatmap that there are two features with the highest correlation to label ON. One positive is the stem MFE and one negative which is the switch-switch interaction. For label OFF, the most correlated feature is the stem MFE. However for the label ON/OFF, the correlations are lower but the highest one is the MFE of the Switch with the GFP sequence.
