## Introduction

Quantum Neural Networks (QNNs) are an emerging field of study combining the principles of quantum mechanics with artificial intelligence. The **GQNN** package offers a platform to implement and study hybrid quantum-classical neural networks, aiming to bridge the gap between theoretical quantum algorithms and practical machine learning applications.

This package allows you to:

- Experiment with QNN architectures.
- Train models on classical or quantum data.
- Explore quantum-enhanced learning algorithms.
- Conduct research in Quantum Machine Learning.

---

## Features

- **Hybrid Neural Networks**: Combines classical and quantum layers seamlessly.
- **Custom Quantum Circuits**: Design and implement your own quantum gates and circuits.
- **Lightweight and Flexible**: Built with Python, NumPy, and scikit-learn for simplicity and extensibility.
- **Scalable**: Easily scale models for larger qubit configurations or datasets.
- **Research-Oriented**: Ideal for academic and experimental use in quantum machine learning.

---

## Installation

### Prerequisites
- Python 3.7 to 3.12 higher or lower version is not supported
- Ensure pip is updated: `pip install --upgrade pip`

### Installing GQNN
#### From PyPI
```bash
pip install GQNN
```

#### From Source
```bash
git clone https://github.com/gokulraj0906/GQNN.git
cd GQNN
pip install .
```

---

## Getting Started

### Basic Example
```python
from GQNN.data.dataset import Data_Read
from GQNN.models.data_split import DataSplitter
from GQNN.models.Linear_model import QuantumClassifier_EstimatorQNN
import numpy as np

# Path to the dataset
data_dir = 'Employee_Salary_Dataset.csv'

# Read and preprocess the dataset
df = Data_Read.Read_csv(data_dir)
print("Original DataFrame (after reading and cleaning):")
print(df.head())

# Apply one-hot encoding to string columns
df_with_encoded_columns = Data_Read.convert_strings_to_numeric()
print("\nDataFrame after One-Hot Encoding of string columns:")
print(df_with_encoded_columns.head())

# Scale the dataset using Min-Max Scaling
scaled_df = Data_Read.Scale_data(method='minmax')
print("\nScaled DataFrame (using Min-Max Scaling):")
print(scaled_df.head())

# Split the dataset into features and target
x = df_with_encoded_columns.drop('Gender_Male', axis=1)
y = df_with_encoded_columns['Gender_Male'].astype(int)

# Split the data into training and testing sets
split = DataSplitter(x, y, test_size=0.75, shuffle=True, random_state=43)
x_train, x_test, y_train, y_test = split.split()

# Convert data to NumPy arrays for processing
x_train = np.array(x_train)
y_train = np.array(y_train)

# Initialize and train the Quantum Neural Network model
model = QuantumClassifier_EstimatorQNN(num_qubits=4, maxiter=60, random_seed=143)
model.fit(x_train, y_train)

# Print the trained model's parameters
model.print_model()

# Evaluate the model and compute accuracy
score = model.score(x_test, y_test)
adjusted_score = 1 - score
print(f"Model accuracy (adjusted): {adjusted_score * 100:.2f}%")
```
