Here you will learn to build three models that are Logistic regression model, the Decision Tree model, and Random Forest Classifier model using Scikit-learn to classify breast cancer as either Malignant or Benign.

We will use the Breast Cancer Wisconsin (Diagnostic) Data Set from Kaggle.

Prerequisite

You should be familiar with the Python Programming language and you should have a theoretical understanding of the three algorithms that is Logistic regression model, Decision Tree model, and Random Forest Classifier model.

Learn Step-By-Step

In this course you will be taught through these steps:

• Section 1: Loading Dataset

  • Introduction and Import Libraries

  • Download Dataset directly from Kaggle

  • 2nd Way To Load Data To Colab

• Section 2: EDA - Exploratory Data Analysis

  • Checking The Total Number Of Rows And Columns

  • Checking The Columns And Their Corresponding Data Types (Along With Finding Whether They Contain Null Values Or Not)

  • 2nd Way To Check For Null Values

  • Dropping The Column With All Missing Values

  • Checking Datatypes

• Section 3: Visualization

  • Display A Count Of Malignant (M) Or Benign (B) Cells

  • Visualizing The Counts Of Both Cells

  • Perform LabelEncoding - Encode The 'diagnosis' Column Or Categorical Data Values

  • Pair Plot - Plot Pairwise Relationships In A Dataset

  • Get The Correlation Of The Columns -> How One Column Can Influence The Other Visualizing The Correlation

• Section 4: Dataset Manipulation on ML Algorithms

  • Split the data into Independent and Dependent sets to perform Feature Scaling

  • Scaling The Dataset - Feature Scaling

• Section 5: Create Function For Three Different Models

  • Building Logistic Regression Classifier

  • Building Decision Tree Classifier

  • Building Random Forest Classifier

• Section 6: Evaluate the performance of the model

  • Printing Accuracy Of Each Model On The Training Dataset

  • Model Accuracy On Confusion Matrix

    • 2nd Way To Get Metrics

  • Prediction

Conclusion

By the end of this project, you will be able to build three classifiers to classify cancerous and noncancerous patients. You will also be able to set up and work with the Google colab environment. Additionally, you will also be able to clean and prepare data for analysis.
