Actionable Persistent Identifier Collections

Mining Actionable Partial Orders in Collections of Sequences

Mining frequent partial orders from a collection of sequences was introduced as an alternative to mining frequent sequential patterns in order to provide a more compact/understandable representation. The motivation was that a single partial order can represent the same ordering information between items in the collection as a set of sequential patterns (set of totally ordered sets of items). Ho...

Persistent Archives for Data Collections

Persistent Archives for Data Collections Reagan

Persistent archives are feasible when examined from the perspective of data collections [1,2]. Issues of ingestion, identification, and certification can then be cast in terms of the information models and technologies needed to manage and federate collections [14, 17, 18]. It is interesting to note that the data and information models needed to federate multiple collections in space are the sa...

Characterizing persistent excitation for the sign-sign equation error identifier

AImtrad--The sign-sign (SS) algorithm is a computationaUy efficient adaptive identifier, often used in signal processing tasks. It is obtained by introducing signum functions on both the regressor and the prediction error multiplicands in the update kernel of the well-known LMS algorithm. This paper gives a deterministic persistent excitation condition on the regressor sequence which guarantees...

Actionable Clustering

In this paper, we define a new notion for a clustering to be useful, called actionable clustering. This notion is motivated by applications across various domains such as in business, education, public policy and healthcare. We formalize this notion by adding a novel constraint to traditional unsupervised clustering. We argue that this notion is different from semi-supervised clustering, superv...
