The New and Computationally Efficient MIL-SOM Algorithm: Potential Benefits for Visualization and Analysis of a Large-Scale High-Dimensional Clinically Acquired Geographic Data

Figure 2

Figure 2(a)–2(c) illustrate the spatial distributions of untrained and MIL-SOM trained datasets. Figure 1(a) represents adult asthma (map units in UTM, meters); Figure 2(b) is childhood asthma (map units in UTM, meters); Figure 2(c) is elevated blood lead levels (map units in state plane, feet).
