Critical analysis of Supervised Learning methods of Dimensional modeling

Critical analysis of Supervised Learning methods of Dimensional modeling Supervised learning method for dimensional modeling: Supervised learning method is far better flexible and beneficial than unsupervised learning method if the supporting information is available. Because if information if available so we can perform a no. of analysis on it. Benefits: 1- High performance in query […]

Supervised and Unsupervised Learning are used in Dimensional modeling Before looking into supervised and unsupervised learning we have to understand that what dimensional modeling is and why is there need of supervised or unsupervised learning so that it can be used in dimensional modeling. Understanding Dimensional Modeling: It is a way of simplifying the entity […]

Improvements suggested for solution proposed in research paper “A Case for Parallelism in Data Warehousing and OLAP” (Download Reference Research Paper) As the solution in research paper is proposed to best fit the situation faced by data warehouses but as it is a proposal so few suggestions can be added to it as below: 1) […]

How the parallel star join works? (Download Reference Research Paper) Star Join Works Involving: i) JDI (Join DataIndexing) ii) i-th dimension tables iii) Use of conventional relational approach As the situation is a process so described to the point as follows: They proposed and demonstrated the implementation by partitioning the table into sub-tables. For example […]

Approach of parallelism used in Data warehouse and OLAP (Download Reference Research Paper) Processor grouping is used to divide and allocate queries to run parallel and data is divided an assigned to different processors as well. In fact parallelism is implemented in two phases: i) A processor group partitioning (d+1 groups) ii) A physical data […]

Critical Review of Research Paper “Towards Systematically Evaluating Flow-level Anomaly Detection Mechanisms” Download Critical Review by Fahad Mahmood: Objective of this research paper: Objective of this research paper is to identify the hurdles in getting valid and correct statistics of network activity due to privacy concerns, anomaly variability and ground truth. And those hurdles are […]

Benefits of leased line Fee for the connection is fixed monthly rate, can vary with the speed, distance or on package customization basis. Thus it is affordable, faster data transfer rates and are cost-effective. It can be divided into different lines for data and voice communication or use the channel for one high speed data […]

Leased line connections Leased line connection are mostly used in our homes and offices and PTCL (Pakistan Telecommunication Company Limited) telephone connection is one of its examples which is in fact a Point-to-Point connection between two computers set up by a common carrier. Initially it was a normal dial-up connection, a leased line which was […]
