**ZipML** is a lightweight AutoML library designed for small datasets, offering essential helper functions like train-test splitting, model comparison, and confusion matrix generation.

## Features

- **Automated Model Training**: Automatically train and compare machine learning models on your dataset.
- **Helper Functions**:
  - Train-test split functionality for easy data management.
  - Confusion matrix generation and the ability to save it as a PNG.
  - Custom logging features for better tracking of your model's performance.
- **Model Comparison**: Compare the performance of different models with ease, providing metrics and visual feedback.
- **CLI Support**: Run machine learning tasks directly from the command line.
- **Extensible**: Add your own models and customize workflows as needed.
- **Visualization Tools**: Includes tools for visualizing model performance metrics, helping to understand model behavior better.
- **Hyperparameter Tuning**: Support for hyperparameter tuning to optimize model performance.
- **Data Preprocessing**: Built-in data preprocessing steps to handle missing values, scaling, and encoding.

## Installation

Install the package via pip:

```bash
pip install zipml
```

Alternatively, clone the repository:

```bash
git clone https://github.com/abdozmantar/zipml.git
cd zipml
pip install .
```

## Usage

### Example Usage with Code

Here's a practical example of how to use ZipML:

```python
import pandas as pd
from zipml.model import analyze_model_predictions
from zipml.model import calculate_model_results
from zipml.visualization import save_and_plot_confusion_matrix
from zipml.data import split_data
from zipml import compare_models
from sklearn.ensemble import RandomForestClassifier, GradientBoostingClassifier
from sklearn.linear_model import LogisticRegression


# Sample dataset
data = {
    'feature_1': [0.517, 0.648, 0.105, 0.331, 0.781, 0.026, 0.048],
    'feature_2': [0.202, 0.425, 0.643, 0.721, 0.646, 0.827, 0.303],
    'feature_3': [0.897, 0.579, 0.014, 0.167, 0.015, 0.358, 0.744],
    'feature_4': [0.457, 0.856, 0.376, 0.527, 0.648, 0.534, 0.047],
    'feature_5': [0.046, 0.118, 0.222, 0.001, 0.969, 0.239, 0.203],
    'target': [0, 1, 1, 1, 1, 1, 0]
}

# Creating DataFrame
df = pd.DataFrame(data)

# Splitting data into features (X) and target (y)
X = df.drop('target', axis=1)
y = df['target']

# Split the data into training and test sets
X_train, X_test, y_train, y_test = split_data(X, y)

# Define models
models = [
    RandomForestClassifier(),
    LogisticRegression(),
    GradientBoostingClassifier()
]

# Compare models and select the best one
best_model, performance = compare_models(models, X_train, X_test, y_train, y_test)
print(f"Best model: {best_model} with performance: {performance}")

# Calculate performance metrics for the best model
best_model_metrics = calculate_model_results(y_test, best_model.predict(X_test))

# Analyze model predictions
val_df, most_wrong = analyze_model_predictions(best_model, X_test, y_test)

# Save and plot confusion matrix
save_and_plot_confusion_matrix(y_test, best_model.predict(X_test), save_path="confusion_matrix.png")
```

### CLI Usage

You can run ZipML from the command line using the following commands:

#### Train a Single Model

```bash
zipml --train train.csv --test test.csv --model randomforest --result results.json
```

- `--train`: Path to the training dataset CSV file.
- `--test`: Path to the testing dataset CSV file.
- `--model`: Name of the model to be trained (e.g., `randomforest`, `logisticregression`, `gradientboosting`).
- `--result`: Path to the JSON file where results will be saved.

#### Compare Multiple Models

```bash
zipml --train train.csv --test test.csv --compare --compare_models randomforest svc knn --result results.json
```

- `--compare`: A flag to indicate multiple model comparison.
- `--compare_models`: A list of models to compare (e.g., `randomforest`, `logisticregression`, `gradientboosting`).
- `--result`: Path to the JSON file where comparison results will be saved.

#### Load a Pre-trained Model and Make Predictions

```bash
zipml --load_model trained_model.pkl --test test.csv --result predictions.json
```

- `--load_model`: Path to the saved model file.
- `--test`: Path to the testing dataset CSV file.
- `--result`: Path to the JSON file where predictions will be saved.

#### Save the Trained Model

To save the trained model after training:

```bash
zipml --train train.csv --test test.csv --model randomforest --save_model trained_model.pkl
```

- `--result`: Path to the file where the trained model will be saved.

### Output

- The output of training and comparison commands will include various performance metrics such as accuracy, precision, recall, and F1 score.
- Results will be saved in JSON format, making them easy to review and analyze.
