Gender & Age Prediction

Machine Learning Model for Demographic Analysis

This deep learning system classifies a person’s age and gender based on facial features using convolutional neural networks (CNNs). Trained on labeled datasets, the model extracts key facial features to predict categories with high accuracy.

Project Overview

Advanced demographic analysis using facial recognition

The Age and Gender Prediction project leverages Machine Learning to classify a person's age and gender based on facial features. Using a deep learning model (such as CNNs), the system is trained on a dataset of human faces with labeled age groups and gender.


The model extracts key facial features and predicts the respective category with high accuracy. Implemented using Python, OpenCV, TensorFlow/Keras, and NumPy, this project finds applications in security, marketing, and personalization.


The dataset is preprocessed for noise reduction, and the model is fine-tuned for optimal performance, ensuring reliable predictions across diverse facial structures.
