Counting the Undercounted: Enumerating Rural Homelessness in Canada

Counting and enumerating aggregate classifiers

We propose a generic model for the “weighted voting” aggregation step performed by several methods in supervised classification. Further, we construct an algorithm to enumerate the number of distinct aggregate classifiers that arise in this model. When there are only two classes in the classification problem, we show that a class of functions that arises from aggregate classifiers coincides wit...

Rural Homelessness: Identifying and Understanding

Lack of awareness or recognition of homelessness The June issue of In Focus provides a synthesis of recent literature on rural homelessness. Homelessness is often conceptualized as an urban issue, which is reflected by the dearth of research on homelessness in rural areas. In reality, homelessness is pervasive in rural communities due to high rates of poverty, unemployment or underemployment, l...

Homelessness and Mental Health: Psycho-social Factors Relating to Homelessness in Canada

Housing is a basic human right and it has strong links with economic, social and cultural aspects of human life. Housing is essential for human survival with dignity. Housing allow people to have privacy, family life, assembly and association. An adequate shelter is the base for human relationships, the free development of the individual and for the playing of an active role in the social and c...

Counting and enumerating pseudo-triangulations with the greedy flip algorithm∗

This paper studies pseudo-triangulations for a given point set in the plane. Pseudo-triangulations have many properties of triangulations, and have more freedom since polygons with more than three vertices are allowed as long as they have exactly inner angles less than π. In particular, there is a natural flip operation on every internal edge. We establish fundamental properties of pseudo-trian...
