Figure 4. Low rank approximations for sample episodes from (a) Modeled data (10 episodes, 100 swabs/day) and (b) Clinical data (8 episodes, 10 swabs/day: every 2 hours during the day and 4 hours overnight) using the four most dominant features obtained from SVD.

For the 3 clinical datasets (different sampling rates) and 1 model simulation dataset, rank-4 approximations were >85% accurate.
