Chapter 9.9, Problem 9.5ARQ
Explanation of Solution
Data Mining:
Data Mining is the extraction of knowledge and data patterns from various raw data sets by examining patterns, trends and other Business Intelligence reports using intelligent methods for classification and prediction.
- Data mining techniques differ from reporting applications, as they are very sophisticated and complex, hence difficult to use.
Difference of factors for reporting and data mining:
| Factors | Reporting | Data mining |
| Type of objective | Assessment | Prediction |
| Company | Target | Netflix |
| Analysis | Simple-summing, totaling | Advance statistics |
| Types | Noninteractive – RFM, Interactive - OLAP |
Cluster Regression Market basket Decision tree Others |
Artificial Intelligence (AI) is the ability of machines to perform activities that require human intelligence. In AI, machines can have vision, and can perform communication, recognition and learning. In AI, machines also have the ability to make decisions.
Benefits:
- Dealing with heavy and mundane tasks become easier with the help of machines.
- In order to gather and analyze Big Data, AI is extremely useful to improve efficiency.
- AI will potential increase cyber security and improve the security of Internet of Things (IOT).
- The accuracy of working on a thing increases a lot with AI.
- Using AI the use of digital assistants will increase which in turn will decrease the need for human resources.
Difference between Data Mining and Machine Learning:
| Data Mining | Machine Learning |
| Data Mining is the extraction of knowledge and data patterns from various raw data sets by examining patterns, trends and other Business Intelligence reports using intelligent methods for classification and prediction |
Machine Learning uses various data mining techniques to extract knowledge from data based on |
|
In order to find patterns among data, Statistics and other | Based on the previously known training data, one can predict the outcome using Machine learning. |
| Data Mining uses both Math and programming methods but inclination toward maths is more. | Machine Learning uses Data Mining techniques to build models that mostly use programming more than maths. |
Data mining techniques are difficult to use:
Curse of Dimensionality:
The Curse of Dimensionality is the observation that is observed that problem arises when one analyses and organizes the data in high dimensional spaces. Working with data becomes more demanding with increase with increase in dimensions.
- With the increase in number of attributes, there is more chance to build easily a model to fit all the sample data but as a predictor it is useless.
- In data mining analyses, having too many attributes is problematic as one of the major activities in Data Mining concerns efficient and effective ways of selecting attributes.
- The amount of data used for Data Mining is huge and one needs to reduce the volume the data in order to meaningfully analyse the data.
Difference between Supervised and Unsupervised Data Mining:
| Unsupervised Data Mining | Supervised Data Mining |
| In Unsupervised Data Mining, before running the analysis, analysts do not create a model or hypothesis. | In Supervised Data Mining, before running the analysis, data miners create a model and apply statistical techniques to the data. |
| Cluster analysis is a technique that uses Unsupervised Data Mining | Regression Analysis is a technique that uses Supervised Data Mining. |
Cluster Analysis:
- Cluster Analysis is a way of arranging data such that data having similar properties are grouped together in a cluster. It is also known as clustering.
Example:
- Using Cluster Analysis, one can find patients with similar diseases from medicine history and demographic data.
Regression Analysis:
Data mining analysis which processes the consequence of a set of variables on other variables is called a regression analysis...

1.[30 pts] Computers generate color pictures on a video screen or liquid crystal display by
mixing three different colors of light: red, green, and blue. Imagine a simple scheme, with
three different lights, each of which can be turned on or off, projecting onto a glass screen:
We can create eight different colors based on the absence (0) or presence (1) of light

Each of these colors can be represented as a bit vector of length 3, and we can apply
Boolean operations to them.
a. The complement of a color is formed by turning off the lights that are on and turning
on the lights that are off. What would be the complement of each of the eight colors
listed above?
b. Describe the effect of applying Boolean operations on the following colors:

Methods (Ch6) - Review
1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java.
There are two methods, method #1 which calculates the square root for positive integers, and
method #2, which calculates the square root of positive doubles (also works for integers).
public class SquareRoot {
public static void main(String[] args) {
}
// implement a loop of your choice here
// Method that calculates the square root of integer variables
public static double myRoot(int number) {
double root;
root=number/2;
double root old;
do {
root old root;
root (root_old+number/root_old)/2;
} while (Math.abs(root_old-root)>1.8E-6);
return root;
}
