OBE: Outlier by Example
Outlier detection in large datasets is an important problem. There are several recent approaches that employ very reasonable definitions of an outlier. However, a fundamental issue is that the notion of which objects are outliers typically varies between users or, even, datasets. In this paper, we present a novel solution to this problem, by bringing users into the loop. Our OBE (Outlier By Exa...
متن کاملBiorthogonal Butterworth wavelets
In the paper we present a new family of biorthogonalwavelet transforms and a related library of biorthogonal symmetric wavelets. For the construction we use the interpolatory discrete splines which enable us to design perfect reconstruction filter banks related to the Butterworth filters. The construction is performed in a “lifting” manner. The proposed scheme is based on interpolation and, as ...
متن کاملBrian Butterworth and Andy Tolmie
What: Our vision is to bring together three previously distinct disciplines [education, psychology and neuroscience] – to focus on a specific common problem: how to promote better learning. This will mean building a new scientific community and a new discipline, educational neuroscience. Why: We now understand better how learning organizes and reorganizes the brain, but there is very little res...
متن کاملGeneralized digital Butterworth filter design
This paper presents a formula-based method for the design of IIR filters having more zeros than (nontrivial) poles. The filters are designed so that their square magnitude frequency responses are maximally-flat at ! = 0 and at ! = and are thereby generalizations of classical digital Butterworth filters. A main result of the paper is that, for a specified half-magnitude frequency and a specified...
