## Overviewđź“ť
This project implements a machine learning pipeline for recognizing handwritten digits using the following techniques:
- Dimensionality reduction with PCA
- Classification using linear SVM
- Performance evaluation on validation set
---
## Dependencies🛠️
```python
from sklearn.datasets import load_digits
from sklearn.decomposition import PCA
from sklearn import svm
```
---
## Datasetđź“‚
The project uses the Digits Dataset from scikit-learn, which contains:
- Handwritten digit images (0-9)
- Features extracted from the images
- Target labels indicating the digit
---
## Implementationđź’»
### 1. Data Loading
```python
digits = load_digits()
x, y = digits.data, digits.target
```
### 2. Dimensionality Reduction
```python
pca = PCA(n_components=8)
pca.fit(x)
x = pca.transform(x)
```
### 3. Model Training and Prediction
```python
svc = svm.SVC(kernel='linear')
svc.fit(x_train, y_train)
y_predicted = svc.predict(x_valid)
```
---
## Running the Code▶️
1. Load the digits dataset
2. Apply PCA transformation
3. Split data into training and validation sets
4. Train SVM classifier
5. Make predictions and evaluate performance
---
## Experimentation⚗️
The following parameters can be modified to optimize performance:
- Number of PCA components
- Training set size
- SVM kernel and parameters
Learning curves can be plotted to visualize the impact of:
- Number of PCA components vs. accuracy
- Training set size vs. accuracy
