Greedy motif search

WebOverview. The basic idea of the greedy motif search algorithm is to find the set of motifs across a number of DNA sequences that match each other most closely. To do this we: … Having spent some time trying to grasp the underlying concept of the Greedy Motif … WebEeager and Lazy Learning. "Eager" is used in the context of "eager learning". The opposite of "eager learning" is "lazy learning". The terms denote whether the mathematical modelling of the data happens during a separate previous learning phase, or only when the method is applied to new data. For example, polynomial regression is eager, while ...
