Intelligent Evidence-Based Management for Data Collection and Decision-Making Using Algorithmic Randomness and Active Learning
Active Learning Algorithmic Information Theory Algorithmic Randomness Evidence-Based Management Kolmogorov Complexity P-Values Transduction Critical States Prediction
2011/7/15
We describe here a comprehensive framework for intelligent information management (IIM) of data collection and decision-making actions for reliable and robust event processing and recognition. This is...
University courses in data mining across the United States are taught primarily in departments of business, computer science/engineering, statistics, and library/information science. Faculty in each o...
Data compression is one of the fundamental research areas in computer science, letting information systems do more with less. It’s the reason the iPod nano can hold thousands of songs instead of hundr...
基于非均匀细分的散乱点云数据精简算法（Algorithm of Scattered Point Cloud Data Reduction Based on Non-uniform Subdivision）
逆向工程 散乱点云 非均匀细分
2009/9/25
针对海量散乱点云数据精简问题，提出了基于非均匀细分的精简算法。采用八叉树结构对点云数据进行空间分割，由分割结果建立k邻域。对k邻域内的散乱点进行二次曲面拟合，以拟合曲面的平均曲率为判据决定是否对八叉树空间实行非均匀细分，细分过程中由数据点之间的最大间隔角决定细分程度。构造曲率差函数，识别出边界数据点，对其进行数据保护。该算法对具有曲率多样化特点的点云数据的精简具有实用性，通过实验验证了该算法的可靠...

Algorithms for many complex computations assume that all the relevant data are available on a single node of a computer network. In the emerging distributed and networked knowledge environments, datab...
LEARNING THE STRUCTURE OF BAYESIAN NETWORK FROM SMALL AMOUNT OF DATA
Bayesian network machine learning algorithm structure learning
2009/6/1
Many areas of artificial intelligence must handling with imperfection of
information. One of the ways to do this is using representation and reasoning with
Bayesian networks. Creation of a Bayesian ...
A Query System for XML Data Stream and its Semanticsbased Buffer Reduction
XML Data Stream Query Optimization Buffer Management SAX
2008/5/20
With respect to current methods for query evaluation over XML data streams, adoption of certain types of buffering techniques is unavoidable. Under lots of circumstances, the buffer scale may increase...
Applying QVT in Order to Implement Secure Data Warehouses in SQL Server Analysis Services
Data Warehouses Security MDA OLAP QVT
2008/4/23
Data Warehouses manage historical information for the decision making process, and this information could be discovered by unauthorized users if security constraints are not established. It is therefo...
A 3.125Gb/s Clock and Data Recovery Circuit Using 1/4-Rate Technique
Clock and Data Recovery (CDR) 1/4-rate frequency detector (QRFD) 1/4-rate phase detector
2007/12/30
This paper describes the design and fabrication of a
clock and data recovery circuit (CDR). We propose a new clock and
data recovery which is based on a 1/4-rate frequency detector (QRFD).
The prop...
