Mobile Price Range Prediction:
Use sales data to build a classification model for mobile phone price ranges. Features include battery power, camera, memory, and connectivity. Split data, apply logistic regression, KNN, SVM (linear and rbf), and evaluate using confusion matrices. Select the most accurate model.
Problem statement:
Create a classification model to predict whether price range of mobile based on certain specifications
Context:
An entrepreneur has started his own mobile company. He wants to give tough fight to big companies like Apple, Samsung etc. He does not know how to estimate price of mobiles his company creates. In this competitive mobile phone market, one cannot simply assume things. To solve this problem, he collects sales data of mobile phones of various companies. He wants to find out some relation between features of a mobile phone (e.g., RAM, Internal Memory etc) and its selling price. But he is not so good at Machine Learning. So, he needs your help to solve this problem. In this problem you do not have to predict actual price but a price range indicating how high the price is

- ram: Random Access Memory in Mega Bytes
- sc_h: Screen Height of mobile in cm
- sc_w: Screen Width of mobile in cm
- talk_time: longest time that a single battery charge will last when you are
- three_g: Has 3G or not
- touch_screen: Has touch screen or not
- wifi: Has wifi or not
- price_range: This is the target variable with value of 0(low cost), 1(medium cost), 2(high cost) and 3(very high cost).
Steps involved:
- Remove handle null values (if any).
- Split data into training and test data.
- Apply the following models on the training dataset and generate the predicted value for the test dataset a) Logistic Regression b) KNN Classification c) SVM Classifier with linear d) RBF kernel
- Predict the price range for test data
- Compute Confusion matrix and classification report for each of these models.
- Report the model with the best accuracy.
