A Python toolkit for the robust evaluation and analysis of seizure detection models.

## Overview

SeizureKit provides a suite of tools designed for researchers and developers working on seizure detection algorithms. It simplifies the process of evaluating model performance at both the epoch and event levels, offering standardized metrics, statistical tests, and post-processing utilities.

## Key Features

- **Epoch-Level Metrics:** Calculate standard classification metrics like F1-score, precision, recall, and specificity on a per-window (epoch) basis.
- **Event-Level Metrics:** Evaluate performance based on seizure events, measuring detection latency, F1-score, and other event-based statistics.
- **Post-Processing:** Includes temporal smoothing and hysteresis thresholding to improve the stability and accuracy of predictions.
- **Statistical Analysis:** Perform statistical significance testing with tools like Bootstrapping and DeLong's test for comparing ROC curves.
- **Visualization (Upcoming):** Tools for plotting ground truth, model probabilities, and predictions.

## Installation

You can install SeizureKit directly from PyPI (once published):

```bash
pip install seizurekit
```

Alternatively, for the latest development version, you can install it from the source:

```bash
git clone https://github.com/Mr-TalhaIlyas/seizurekit.git
cd seizurekit
pip install -e .
```

## Usage

SeizureKit can be used both as a command-line tool for quick evaluations and as a library in your Python projects for more complex workflows.

### As a Command-Line Tool

After installation, you can use the `seizurekit` command to evaluate your model's predictions. You need a ground truth file and a model probabilities file (either `.npy` or `.csv`).

```bash
# Display help and all available options
seizurekit --help

# Example: Run a full evaluation
seizurekit path/to/ground_truth.npy path/to/model_probabilities.npy --smoothing_window 5 --hyst_high 0.7 --hyst_low 0.3
```

### As a Python Library

Integrate SeizureKit's functions directly into your analysis scripts.

```python
import numpy as np
from seizurekit.eval_epochs import calculate_classification_metrics
from seizurekit.eval_events import calculate_event_level_metrics

# 1. Load or create your data
y_true = np.array([0, 0, 1, 1, 1, 0, 0, 0, 1, 1, 0, 0, 0, 1, 1, 1, 1])
y_prob_1 = np.array([0.1, 0.2, 0.8, 0.9, 0.4, 0.3, 0.1, 0.4, 0.85, 0.95, 0.2, 0.1, 0.3, 0.99, 0.98, 0.97, 0.5])
y_prob_2 = np.array([0.05, 0.15, 0.75, 0.85, 0.35, 0.25, 0.05, 0.35, 0.8, 0.9, 0.15, 0.05, 0.25, 0.95, 0.9, 0.92, 0.45])

all_targets = y_true
all_probs = {'my_model': y_prob_1,
              'my_model_2': y_prob_2}
eval_config = {'window_duration': 10, 'detection_tolerance': 30}

# 2. Run epoch-level evaluation
print("--- Epoch-Level Metrics ---")
epoch_results = calculate_classification_metrics(
    all_probs,
    all_targets,
    eval_config,
    smoothing_window=3,
    hysteresis_high=0.5,
    hysteresis_low=0.5
)

# 3. Run event-level evaluation
print("\n--- Event-Level Metrics ---")
event_results = calculate_event_level_metrics(
    all_probs,
    all_targets,
    eval_config,
    smoothing_window=3,
    hysteresis_high=0.5,
    hysteresis_low=0.5
)
```
Running above code produces output below;
```shell
