We describe a recommender system in the domain of grocery shopping. While recommender systems have been widely studied, this is mostly in relation to leisure products (e.g. movies, books and music) with non-repeated purchases. In grocery shopping, however, consumers will make multiple purchases of t ...

In this talk, we consider the problem of learning a target function that belongs to the linear span of a large number of reproducing kernel Hilbert spaces. Such a problem arises naturally in many practice situations with the ANOVA, the additive model and multiple kernel learning as the most well kno ...

Support vector machine (SVM) has been one of the most popular learning algorithms, with the central idea of maximizing the minimum margin, i.e., the smallest distance from the instances to the classification boundary. Recent theoretical results, however, disclosed that maximizing the minimum margin ...

A bike sharing system deploys bicycles at many open docking
stations and makes them available to the public for
shared use. These bikes can be checked-in and checked-out
at any of the docking stations. Predicting daily visits is important
for service providers to optimize bike allocation and
st ...

Inferring predictive maps between multiple input and multiple output
variables or tasks has innumerable applications in data science.
Multi-task learning attempts to learn the maps to several output
tasks simultaneously with information sharing between them. We
propose a novel multi-task learnin ...

Most existing semi-supervised learning methods are based on the smoothness assumption that data points in the same high density region should have the same label. This assumption, though works well in many cases, has limitations. To overcome this problems, we introduce into semi-supervised learning ...

Uncertain data are inherent in some important applications, such as environmental surveillance, market analysis, and quantitative economics research. Uncertain data in those applications are generally caused by factors like data randomness and incompleteness, limitations of measuring equipment, dela ...

This paper introduces mass estimation—a base modelling
mechanism in data mining. It provides the theoretical basis
of mass and an efficient method to estimate mass. We show
that it solves problems very effectively in tasks such as information
retrieval, regression and anomaly detection. The
models, ...

This paper introduces the first generic version of data dependent dissimilarity and shows that it provides a better closest match than distance measures for three existing algorithms in clustering, anomaly detection and multi-label classification. For each algorithm, we show that by simply replacing t ...
