# Predicting Diabetes using KNeighborsClassifier.

![accuracy vs n_neighbors graph](https://github.com/SoumyaCO/KNeighbors-classifier-diabetes/blob/main/knn-image.png)

### 1. 🎯 Aim: 

Train a model with the diabetes data to predict a patient has diabetes or not.

### 2. 📚 Concepts Covered:

* Data Manupulation

* Feature Engineering

* Scaling a dataset

* Hyperparameter tuning with `GridSearchCV`

* `confusion_matix`

* F1_score, precision

* Data Visualization

### 3. 🔎 Approach: 

> * Importing the data

> * Understanding the features

> * Cleaning the data

> * Scale and Impute the data

> * Instantiate a `KNeighborsClassifier()` model from `sklearn.neighbors`

> * To have the right number of `n_neighbors` performed `GridSearchCV`

> * After getting the `grid.best_params_` visualized `confusion_matrix`

> * Calculated Precision, Recall, F1_score

> * Lastly visualized a accuracy vs n_neighbors plot

👉 In the notebook I've provided detailed codes and concepts. If you like it please give a star ⭐️

❗If you are trying it in **google colab** you have to upload the dataset [dibetes.csv]
