# Critical Period Analysis on Face Recognition

[![License: MIT](https://img.shields.io/badge/License-MIT-brightgreen.svg)](LICENSE)

We provide a full computational account for face-learning behaviors by using deep artificial neural networks and show that impaired face-learning can be restored when providing information within a critical period.

## Data Preprocessing

We applied foveate blurring to generate the data using different eye fixations.

## Observations

We found the critical period played an important role in the learning phase of face recognition.

## Recovery

We also proposed a method to recover the impairments caused during the Critical Period with an extremely low learning rate.

With Knowledge Distillation and Attention Transfer, we recovered the accuracy of the impaired model.

 

The recovery is also confirmed by statistical metrics
