A Rank Graduation Accuracy Measure

Place Rank: a New Accessibility Measure

Accessibility is the potential of opportunities for interaction in an urban context. The widely used accessibility measure consists of the number of opportunities that can be reached within a region or a period of time multiplied by a cost or impedance function for reaching these opportunities. This measure assumes that all people living within a region will follow a certain impedance function ...

Place Rank: A Flow-based Accessibility Measure

Accessibility measures the potential of opportunities for interaction. This paper proposes a new flow-based accessibility measure, “place rank” utilizing origin-destination information. Both impedance and value of opportunities are embedded in the dataset that includes origins and destination of each person utilizing the studied region. Individuals contribute to the accessibility level in their...

Predicting a Rank Measure for Stock Returns

RankDCG: Rank-Ordering Evaluation Measure

Ranking is used for a wide array of problems, most notably information retrieval (search). Kendall’s τ , Average Precision, and nDCG are a few popular approaches to the evaluation of ranking. When dealing with problems such as user ranking or recommendation systems, all these measures suffer from various problems, including the inability to deal with elements of the same rank, inconsistent and ...

Accuracy in Image Measure

The aim of this paper is to show how image points can be extracted accurately. We will restrict our search to speciic points identiied by corners, which are stable given a sequence. Our approach makes use of a model{based corner detector. It matches a part of the image containing a corner against a predeened corner model. Once the tting is accomplished, the position of the corner in the image c...
