Overview

This project employs the K-Nearest Neighbors (K-NN) algorithm to classify cancer cells as either benign or malignant. With an impressive accuracy rate of 96.50%, this model can be used for medical diagnosis and research purposes.

Dataset

The project uses the Cancer_Data.csv dataset. This dataset contains 569 entries with 30 features, and each entry is labeled as benign (B) or malignant (M).

Project Structure

The project is organized into the following sections:

  1. Library and Input File: This section imports necessary libraries and loads the dataset.

  2. Data Loading and Editing: The dataset is loaded, and unnecessary columns (such as 'Unnamed: 32' and 'id') are removed. The 'diagnosis' column is also converted to numerical values (1 for 'M' and 0 for 'B').

  3. Normalization: Data normalization is performed to scale the values between 0 and 1, preventing high or low values from introducing errors in the model.

  4. Train Test Split: The dataset is divided into training and testing sets for model training and evaluation.

  5. Initialize K-NN Classifier: The K-NN classifier is initialized with a specified number of neighbors (k).

  6. Model Training: The K-NN model is trained on the training data.

  7. Model Evaluation: The model's performance is evaluated, including a confusion matrix.

  8. Model Result: The training progress is monitored, and the model's performance is assessed.

Requirements

To run the project, make sure you have the following Python libraries installed:

  • NumPy
  • pandas
  • scikit-learn
  • seaborn
  • matplotlib

You can install these libraries using pip:

pip install numpy
pip install pandas
pip install scikit-learn
pip install seaborn
pip install matplotlib

Getting Started

Installation

  1. Clone the project repository:
git clone https://github.com/Prometheussx/Kaggle-Notebook-Cancer-Prediction-ACC96.5-With-K-NN.git
cd Kaggle-Notebook-Cancer-Prediction-ACC96.5-With-K-NN
  1. Ensure you have Python and the required libraries installed.

Data Preparation

  1. Download the Cancer_Data.csv dataset and place it in the project directory.

  2. Follow the code in the "Data Loading and Editing" section to load and preprocess the dataset.

Usage

Training the Model

Execute the Python code in the repository files to perform K-NN classification and train the model.

Example: knn_classification(x_train, y_train, x_test, y_test, k=5)

Evaluation

The model's performance is evaluated with metrics such as accuracy and a confusion matrix.

Results

The project attains an accuracy of 96.50% in classifying cancer cells. Training progress and results are visualized in the README.
