Drowsiness detection using EEG signals using DL

[KamakshiOjha]

Deep Learning Simplified Repository (Proposing new issue)

:red_circle: Project Title : Drowsiness Detection Using EEG Signals
:red_circle: Aim : To develop a deep learning model to detect drowsiness from EEG signals using various algorithms and compare their performance to identify the best-fitted algorithm based on accuracy scores.
:red_circle: Dataset : https://figshare.com/articles/dataset/EEG_driver_drowsiness_dataset/14273687
:red_circle: Approach :

1. Exploratory Data Analysis (EDA):

   • Analyze and preprocess the EEG dataset.
   • Visualize EEG signals and class distributions.

2. Model Development:

   • Implement the provided deep learning model using TensorFlow and Keras.
   • Develop and implement three additional models:
     1. Convolutional Neural Network (CNN).

3. Model Training and Evaluation:

   • Train each model on the EEG dataset.
   • Evaluate models using accuracy, precision, recall, and F1-score.
   • Compare performances to identify the best model.

4. Visualization and Conclusion:

   • Visualize training and validation metrics.
   • Provide insights and conclusions based on model comparisons.
