1. The inconsistent data definitions and varied dimensions and measures are present in independent data marts.
2. When it comes to OLAP, analytics is not a major activity.
3. Ad-hoc reports are the ones that resemble routine reports.
4. Optimization is involved in clustering techniques since the aim is to create groups with maximum similarity among their members.
5. Neural networks have been applied to business classification problems due to their ability to learn data, nonparametric nature of learning models, and generalization capabilities.
6. All of the above are reasons why neural networks are used in business classification problems.
The main processing elements of a neural network are individual neurons. A software suite is created when several software products are integrated into a system. When using rules of thumb, one does not have to completely rethink what to do every time a
...similar problem is encountered. Common tools used for supervised induction include neural networks, decision trees, and if-then-else rules that do not have to have a tree structure. Data cleansing is a critical aspect of data warehousing that involves reconciling conflicting data definitions and formats organization-wide.
11. One of the activities that is not considered major for OLAP is analytics. 12. OLAP provides the capability for modeling, analysis, visualization, and all of the above to large sets of data. 13. One of the steps in text mining is calculating the weights of the remaining terms, which involves calculating the frequency at which a given word appears. 14.
Data mining, which involves the extraction of mathematical patterns from large data sets (15), can be compared to the way networks of neurons in the human brain function (16). Similarly, artificial neural networks are mad
up of interconnected artificial neurons (17) and expert systems rely on inference engines as their "brain" (18). Nowadays, organizations recognize that unstructured knowledge contained within documents stored in their knowledge repositories can provide a significant competitive advantage.
Mathematical structures called neural networks are proficient in dealing with a vast number of variables and have the ability to learn. A status report is a reliable source for obtaining current information on an item's present condition, like orders, expenses, or production quantity. The fundamental components of a knowledge base within an expert system consist of facts, heuristics, and rules.
Forecasting and estimation involve using patterns in large datasets to predict future values. The three-tier architecture of data warehousing offers the benefit of separating functions and eliminating resource constraints, allowing for easy creation of data Mart. Major BI software companies do not provide the capability of reporting deletion.
Business intelligence relies on business analytics for providing models and analytical procedures. Sequence discovery is the process of identifying associations over time. Data archaeology is one of the tasks in data mining. The function of summing the weighted input elements is performed by the summation function in each processing element. Machine learning is used for knowledge refinement in an expert system.
Cluster analysis serves as an exploratory method in data analysis to address classification problems (31), while ETL (extract, transfer, and load) process involves extracting, transferring and loading data. Transformation is accomplished through the use of rules or lookup tables.
