An Efficient Normalized Rank Based SVM for Room Level Indoor WiFi Localization with Diverse Devices

Figure 7

Localization accuracy comparison in the case of unique exemplification per location based on linear SVM. (a) shows the attained accuracy based on RSSI value. (b) shows the accuracy in the case of applying the inverse rank value. (c) shows the accuracy in the case of applying the rank transformation value. (d) Accuracy based on the normalized rank transformation. (#) The inverse rank is the converted absolute RSSI vector by considering the opposite direction of (3).
