It depends on circumstances like the embedding dimension,<br \/>\n\tthe time series predictability, or the base frequency, whether the driving<br \/>\n\tforce itself or a slower subcomponent is detected. Interestingly, we observe<br \/>\n\ta swift phase transition from one regime to another and it is the<br \/>\n\tobjective of this work to quantify the in<br \/>\n\tuence of various parameters<br \/>\n\ton this phase transition. We conclude that what is perceived as slow by<br \/>\n\tSFA varies and that a more or less fast switching from one regime to<br \/>\n\tanother occurs, perhaps showing some similarity to human perception.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Publication: Wolfgang Konen, Patrick Koch, How slow is slow?
