Vision-based traffic light detection has been widely studied over the past decade. However, it is still a challenging task to build a real-time and robust classifier-based detector without a high dependency on prior knowledge. In this paper, we have a deep look at the design of features and detection mechanism in the domain of traffic light detection; propose a multi-scale and multi-phase detector...
In this paper, we formulate a novel problem for finding black hole and volcano patterns in a large directed graph. Specifically, a black hole pattern is a group which is made of a set of nodes in a way such that there are only in links to this group from the rest nodes in the graph. In contrast, a volcano pattern is a group which only has out links to the rest nodes in the graph. Both patterns can...
This article is conducting a study on the demand forecast from the distribution network system composed of m-distribution centers and n-retailers. We analyze the characteristics of the regional logistics network. Use the Dijkstra shortest path algorithm and gain the shortest path distribution, based on which the inventory demand forecasting model which can obtain the total demand of each distribution...
Given a large transaction database, association analysis is concerned with efficiently finding strongly related objects. Unlike traditional associate analysis, where relationships among variables are searched at a global level, we examine confounding factors at a local level. Indeed, many real-world phenomena are localized to specific regions and times. These relationships may not be visible when...
