The Normal Distribution has:
Mean=Median=Mode
Symmetry about the center
50% of value less than the mean and 50% greater than the mean
1(b) Weibull

Data Mining Methods: Unit 4
Correlation and Simple Linear Regression
Interpretation of the correlation coefficient
Possible range: [-1, 1]
-1: perfect negative linear relationship
0: no linear relationship,
1: perfect positive linear relationship.
Regression: Objective
To predict one variable from other variables.
To explain the variability of one variable using the other variables.
Predicts scores on one variable from the scores on a second variable.
Response variable: predicting variable (Y )
Predictor variable: predictions based on this variable (X)
Simple regression:
Only one predictor variable; otherwise multiple regression
Linear regression:
Predictions of the response variable (Y ) is a linear function of the predictor variable (X)

Theory:
Data Preprocessing in the Data Mining Process:
The data mining/KDD process
Why data preprocessing?
Issues in Data Preprocessing:
Data Cleaning
Data Transformation
Variable Construction
Data Reduction and Discretization
Data Integration
The data mining/KDD Process:
Understanding customer: 10%-20%
Understanding data:20-30
Prepare data: 40-70%
Build Models: 10-20%
Evaluate models: 10%-20%
Take action:10%20%
Why data mining?
Real – world data is dirty
Low data quality anyway a huge problem in data mining
Garbage in,garbage out
Different methods, different requirements
R Working Codes for data mining:
R code is case sensitive:
I am doing it from professors sheet.
dim means dimension
This line i could not make work:
hist(Ozone,breaks=25,ylim=(c(0,45)),main=”Original data”)
And another question how the imputation works
Exercise 2 (K)= I have to find the answers
Exercise 3: Answer:

Same output but the code is in diffrent approach.

I have started this course from Udemy and will complete soon with all my effort In Sha Allah:
Book Recommendation: Effective Java, Second Edition, Joshua Bloch
Harnessing Java by Kishori Shoron
Head First Java
1st video:
Installed JDK
Environment Setup
Made Hello.java with Notepad++
then done javac Hello from cmd:
It made Hello class which is platform independent
2nd Video:
|
1 2 3 4 5 6 7 8 9 10 |
public class HelloWorld1{ public static void main(String[] args){ System.out.println("Hello World!!"); } } //when it has public modifier then you need to make the file name //and class name same if it is not then it's okay |

E:\javaudemy>javac Hello.java Hello.java:1: error: class HelloWorld1 is public, should be declared in a file named HelloWorld1.java public class HelloWorld1{ ^ 1 error |

Software Engineer | Polyglot Programmer | Gym Lover | Cyclist | Algorithm Addict | Programming and Research enthusiast | Life Long Passionate Learner | Love CSE, Backend and Data
Hi, thanks for your interest on my blog 🙂 I am Syed Ahmed Zaki, from Germany. This is my blog “Zakilive.Com” for sharing my knowledge and passion with you all.
I was born in a beautiful country of south asia named Bangladesh. I am a Computer Science and Engineering graduate and currently doing my post graduation in Germany. I am passionate, dedicated, hardworking about my tasks and fond of Algorithms, Competitive Programming, Mathematics, Research in data science(Machine Learning, AI, NLP, Deep Learning), bioinformatics and IoT. I also love software engineering. In software development field I prefer Web Application Engineering.
In my bachelor study life, I tried to participate in several programming contests(online, onsite, intra etc.) and passed some time in ACM training class for sharpening my logical skills. As an ordinary people it was little bit tough for me alongside with academic pressure, thesis and research paper writing but I love challenges so I always tried to push my limits though still I need to improve a lot in everything but I always trust in this quote “Hard work beats talent”. That quote I have learned from my life through bodybuilding of 6 years since 2012 and after losing 33 KG fat in 4 months from 101 KG I developed my fit physique, so I respectfully believe in this sentence and relate this with CSE field. I also love to learn from my failures. I hate excuses while working professionally and I love trying to finish my work with perfection till the last moment before deadline.
I also love to explore and play with new technologies and try to implement it with innovative ideas. In my bachelor university life, I always tried to learn from the basics of Computer Science. So, I have tried to gather Networking to Database Knowledge, OS fundamentals to OOP etc. all fundamental core basics in my skillset in a practical approach.
Alongside with developing some web applications in core php and laravel framework I have also tried to build games with unity3d game engine, built 2 android apps, experimented machine learning with python, data mining with WEKA, AI chatbot, IoT based weather station and some more project works for my undergraduate courses. As I am language and platform agnostic, I enjoyed and learned a lot from all of these works. I also love teamwork. Alongside software engineering and different extra curricular activities I also love teaching. I am also proficient at working with linux and windows based OSes and I feel so lucky if I get chance to contribute in opensource projects. In my linkedin profile you will find more details about me.
However, I am actually a knowledge seeker and life long passionate learner who tries to make his weakness as strength, I was a serious student of all the courses in CS academia that can solve real life problems as I love to explore knowledge in a crafted manner. I love to study books, blogs or whatever philosophically solve my curiosity. For that, I maintain a good collection of various technological, scientific and philosophical books in my small library. Knowledge sharing, analytical thinking, practice and passing the passion of mine with you is one of my motivations for running this blog. I practice to hone my skills with trying to improve my programming and developing skillset day by day and what I learn, I never forget to share here for you.
In my free time I love to do cycling or gym or play racing games in my android phone or watch animated movies and also love to promote positive, fit and healthy lifestyle among people.

Currently I am working with python technologies. If you have any opportunity/business to work with me or any other query kindly say just hi to me at my mail:
