Sentiment-Analysis
Need to get daily analysis of product and extract the sentiments, emotions etc. using Amazon data and correlate it with NSE or BSE stock market over past 3 months.
Car-Price-Prediction
The objective of this analysis is to provide a reliable regression model to predict the price of a car based on the variables provided as accurately as possible. The idea is for this to be used in the future for any new cars that would added to the dataset going forward.
DECISION_TREE_COMPANY
About the data: Let’s consider a Company dataset with around 10 variables and 400 records. The attributes are as follows: Sales -- Unit sales (in thousands) at each location Competitor Price -- Price charged by competitor at each location Income -- Community income level (in thousands of dollars) Advertising -- Local advertising budget for company at each location (in thousands of dollars) Population -- Population size in region (in thousands) Price -- Price company charges for car seats at each site Shelf Location at stores -- A factor with levels Bad, Good and Medium indicating the quality of the shelving location for the car seats at each site Age -- Average age of the local population Education -- Education level at each location Urban -- A factor with levels No and Yes to indicate whether the store is in an urban or rural location US -- A factor with levels No and Yes to indicate whether the store is in the US or not The company dataset looks like this: Problem Statement: A cloth manufacturing company is interested to know about the segment or attributes causes high sale. Approach - A decision tree can be built with target variable Sale (we will first convert it in categorical variable) & all other variable will be independent in the analysis.

LOGISTIC_REGRESSION_AFFAIRS_DATA
I have a dataset containing family information of married couples, which have around 10 variables & 600+ observations. Independent variables are ~ gender, age, years married, children, religion etc. I have one response variable which is number of extra marital affairs. Now, I want to know what all factor influence the chances of extra marital affair. Since extra marital affair is a binary variable (either a person will have or not), so we can fit logistic regression model here to predict the probability of extra marital affair. install.packages('AER') data(Affairs,package="AER")
LOGISTIC_REGRESSION_BANK_DATA
Output variable -> y y -> Whether the client has subscribed a term deposit or not Binomial ("yes" or "no")

Chronic_Diseases_Prediction
The data was taken over a 2-month period in India with 25 features ( eg, red blood cell count, white blood cell count, etc). The target is the 'classification', which is either 'ckd' or 'notckd' - ckd=chronic kidney disease. There are 400 rows
Classifier-Model
Worked on IRIS Data set to classify class if we feed any new data.I was able to build Decision Tree model was giving good accuracy around 91%. Decision Tree was build with “Entropy” & “Gini Index".

Health-Insurance---JOB-A-THON---Analytics-Vidhya
Your Client FinMan is a financial services company that provides various financial services like loan, investment funds, insurance etc. to its customers. FinMan wishes to cross-sell health insurance to the existing customers who may or may not hold insurance policies with the company. The company recommend health insurance to it's customers based on their profile once these customers land on the website. Customers might browse the recommended health insurance policy and consequently fill up a form to apply. When these customers fill-up the form, their Response towards the policy is considered positive and they are classified as a lead. Once these leads are acquired, the sales advisors approach them to convert and thus the company can sell proposed health insurance to these leads in a more efficient manner. Now the company needs your help in building a model to predict whether the person will be interested in their proposed Health plan/policy given the information about: Demographics (city, age, region etc.) Information regarding holding policies of the customer Recommended Policy Information

Pima-Indians-Diabetes-Database
Context This dataset is originally from the National Institute of Diabetes and Digestive and Kidney Diseases. The objective of the dataset is to diagnostically predict whether or not a patient has diabetes, based on certain diagnostic measurements included in the dataset. Several constraints were placed on the selection of these instances from a larger database. In particular, all patients here are females at least 21 years old of Pima Indian heritage. Content The datasets consists of several medical predictor variables and one target variable, Outcome. Predictor variables includes the number of pregnancies the patient has had, their BMI, insulin level, age, and so on.

Twitter-Tweet-Analysis
Twitter has become an important communication channel in times of emergency. The ubiquitousness of smartphones enables people to announce an emergency they’re observing in real-time. Because of this, more agencies are interested in programmatically monitoring Twitter (i.e. disaster relief organizations and news agencies.But, it’s not always clear whether a person’s words are actually announcing a disaster
