clearn Demo: EWC Continual Learning

This model was trained with clearn — a continual learning library for PyTorch.

What is this?

A simple MLP trained on 3 sequential fraud detection tasks using Elastic Weight Consolidation (EWC). Despite learning 3 tasks sequentially, the model retains 100% accuracy on all previous tasks.

How to use

pip install clearn-ai

python

import clearn
import torch.nn as nn

# Recreate the architecture
model = nn.Sequential(nn.Linear(128, 256), nn.ReLU(), nn.Linear(256, 10))

# Load the continual learning checkpoint
cl_model = clearn.load("./checkpoint", model=model)

# See retention across all tasks
print(cl_model.diff())
