Data-driven Geography
The context for geographic research has shifted from a data-scarce to a data-rich environment, in which the most fundamental changes are not just the volume of data, but the variety and the velocity at which we can capture georeferenced data; trends often associated with the concept of Big Data. A data-driven geography may be emerging in response to the wealth of georeferenced data flowing from...
متن کاملAn Analysis of Response Times in Adaptive Practice of Geography Facts
Online educational systems can easily measure both answers and response times. Student modeling, however, typically focuses only on correctness of answers. In this work we analyze response times from a widely used system for adaptive practice of geography facts. Our results show that response times have simple relationship with the probability of answering correctly the next question about the ...
متن کاملAn Adaptive Approach to Increase Accuracy of Forward Algorithm for Solving Evaluation Problems on Unstable Statistical Data Set
Nowadays, Hidden Markov models are extensively utilized for modeling stochastic processes. These models help researchers establish and implement the desired theoretical foundations using Markov algorithms such as Forward one. however, Using Stability hypothesis and the mean statistic for determining the values of Markov functions on unstable statistical data set has led to a significant reducti...
متن کاملMinimum basic data set in general practice: definitions and coding.
A minimum basic data set (MBDS) was designed and used in general practice. The most important purpose and need for establishing such a data set is to assist in the provision of patient care. MBDS is designed to meet common needs for many general practitioners. Minimum means that individual programmes or the GP are free to collect as much additional data as they may wish. The MBDS includes two k...
متن کاملA Sensitivity-Adaptive ρ-Uncertainty Model for Set-Valued Data
Set-valued data brings enormous opportunities to data mining tasks for various purposes. Many anonymous methods for set-valued data have been proposed to effectively protect individuals privacy against identify linkable attacks and item linkage attacks. In these methods, sensitive items are protected by a privacy threshold to limit the re-identified probability of sensitive items. However, lots...
