# **Brain MRI Age Classification Using Deep Learning**

3-
This example shows how to work with an MRI brain image dataset and how to use transfer learning to modify and retrain ResNet-18, a pretrained convolutional neural network, to perform image classification on that dataset.

The MRI scans used in this example were obtained during a study \[1\] of social brain development conducted by researchers at the Massachussets Institute of Technology (MIT), and are available for download via the OpenNEURO platform:

This example shows how horizontal midslice images from the brain MRI scan volumes can be classified into 3 categories according to the chronological age of the participant:
9-
1. Participants Aged 3-5
10-
2. Participants Aged 7-12
11-
3. Participants older than 18, classified as Adults

This example works though multiple steps of a deep learning workflow:
16-
- _Exploring_ a public brain MRI image dataset
17-
- _Preparing_ the dataset for deep learning
18-
- _Training_ a deep learning model to perform chronological age classification
19-
- _Evaluating_ the trained model
