Implementation of Fractal Dimension and Self-Organizing Map to Detect Toxic Effects of Toluene on Movement Tracks of Daphnia magna

Figure 4

The map trained by using the SOM for pattering movement segments of D. magna in 5 s. (a) Six clusters classified by the SOM (“C” represents movement segments before treatments, while “T” stands for movement segments after treatments). (b) Profile of the parameters matching the clusters based on the trained SOM. The values in the vertical bar in the top row indicate normalized parameters. (c) Dendrogram according to Ward’s linkage method.
