The classification scheme of galaxies, quasars, and stars is one of the most fundamental in astronomy. The early cataloguing of stars and their distribution in the sky has led to the understanding that they make up our own galaxy and, following the distinction that Andromeda was a separate galaxy to our own, numerous galaxies began to be surveyed as more powerful telescopes were built. This dataset aims to classification stars, galaxies, and quasars based on their spectral characteristics.Dataset Link: https://www.kaggle.com/fedesoriano/stellar-classification-dataset-sdss17Model Accuracy: 97%Class 0: GalaxyClass 1: QSOClass 2: StarClassification Matrix: less

The dataset includes prices of flight tickets for various airlines between March and June of 2019 and between various cities.
The project aims to predict Flight ticket prices as accurately as possible.
'r2_score' has been used to check the model's performance.

The Project’s aim is to predict whether a customer will cancel his/her’s hotel room booking or not.
The data contains booking information for a 'city hotel' and a 'resort hotel.' In addition, it contains information such as when the booking was made, length of stay, the number of adults, children, and babies, and the number of available parking spaces, among other things.
The "Accuracy_score" metric has been used to measure that model's performance. less

Introduction:
Used car Price Prediction is used in predicting the price of a used car with different features included like age of the car, how many km covered, Mileage, Fuel type, Owner, and many more.
New car prices are fixed by the manufacturers with additional costs that include government additional amounts in the form of taxes. So, buying a new car means investing a large amount of money and sometimes customers don’t have that many funds. So, nowadays used car sale is increasing and there are many different apps for the same. Used Car price prediction uses other models from where we get to know the best price for our cars. It tells us this according to its market price.
This model helps the client predict his car’s market price if he wants to sell or purchase a used car.
Data:
The dataset I used here is downloaded from Kaggle. It includes 14 different features like name, model, brand, owner type, mileage, Kilometers driven, engine, power, transmission, etc.
You Can download the dataset from the link provided: https://www.kaggle.com/avikasliwal/used-cars-price-prediction.
Data Pre Processing
Data Cleaning, Data pre-processing, Exploratory data analysis have been applied to data, and we will be discussing that in-depth further.
There is one more assumption for this dataset that the Price value should be greater than the New_Price as the Price is the actual price of the car and the New_Price is the price calculated but in this dataset, we see that the New_Price is greater than Price. So, we will assume the Price as the New_Price of the car and drop New_Price values.
Data cleaning includes to check the null values, deleting duplicate rows, imputation of null values and even change in column name, replacing of blank space, removing string part from integer type like from mileage column removing ‘km/h’, ’kmpl’, ‘CC’ from engine to get the integer or float values which can be computed.
data['Mileage'] = data['Mileage'].str.replace(r'kmpl', '')
data['Engine'] = data['Engine'].str.replace(r' CC', '')
data['Power'] = data['Power'].str.replace(r'bhp', '')
Every data needs to be pre-processed first. Different pre-processing functions are written like:
getCountOfMissingValuesPerColumn(): Gives us the count of missing values per column.
display(preprocessing.getCountOfMissingValuesPerColumn(data, exclude_Zero_percent=True))
convertObjectColumnsToCategory(): Every Object datatype column is converted into category type.
preprocessing.convertObjectColumnsToCategory(cols)
convertFloatColumnsToInt64(): every float type column in integer.
dropMissingColumnsByThreshold(): We dropped the missing values by putting some threshold, here I used above 80% of missing values columns should be dropped.
printValueCountsOfCatagoricalColumns(): To print how many values are there in categorical column.
In the dataset, there is a feature New_Price with maximum null values which is dropped using drop by a threshold value.
EDA: While exploring data, we will look at the different combinations of features with the help of visuals. This helps us to understand our dataset better and give us some hints about the pattern in the data.
Many graphs are used to understand the data like count plot, boxplot, bar plot, face grid, etc.
Feature Engineering: Most of the feature engineering tasks are covered in data pre-processing. Here we updated the categorical values to numbers. For e.g.:
data['Fuel_Type'] = data['Fuel_Type'].str.replace(r'LPG', '3')
data['Fuel_Type'] = data['Fuel_Type'].str.replace(r'Electric', '4')
data['Transmission'] = data['Transmission'].str.replace(r'Manual', '1')
data['Transmission'] = data['Transmission'].str.replace(r'Automatic', '0')
data['Owner_Type'] = data['Owner_Type'].str.replace(r'First', '1')
data['Owner_Type'] = data['Owner_Type'].str.replace(r'Second', '2')
Modeling:
This makes it easy to implement different models and get accurate values for its accuracy score, confusion matrix, TP, TN, FP, and FN values.
The main features used to calculate the price of a used car are: Year, Km drove, Fuel Type, Transmission, Owner Type, Mileage.
We used different models here like Linear Regression, Random Forest Regressor, Gradient Boosting Regressor, Grid Search CV, ANN. I have split the dataset into the train and test with 80 and 20 respectively.
Linear Regression: Linear regression was the first type of regression analysis, used extensively in practical applications. Some models linearly depend on their unknown parameters and are easier to fit than models which non-linearly depend on their parameters and because of this statistical property of the resulting variable is easier to determine. Regression can be used to identify the effect independent variable(s) have on a dependent variable. Solves problems like finding the age, market spending, income, etc.
Grid Search CV: This is a method for adjusting the features in... less

Linear regression performs the task to predict a dependent variable value (y) based on a given independent variable (x). When there is a single input variable (x), the method is referred to as 'Simple Linear Regression'. In this usecase the dataset which we used contains 7 columns which are age, sex, bmi, children, smoker, region, and charges. The charges column acts as a target variable and the remaining columns are features. less
