Semi-Supervised Pre-training for Transferable Features
To overcome limitations of supervised pre-training, this study introduces a semi-supervised approach combining Barlow Twin (BT) loss and activation regularization. This method aims to learn richer, more transferable features, crucial for Latent Replay scenarios where the feature extractor is often frozen.
Case Study: Boosting CIL Performance with SSL
Our experiments on CIFAR50+5X10 demonstrated that integrating a semi-supervised pre-training approach (combining Barlow Twin loss and activation regularization) significantly improved the overall Class-Incremental Learning (CIL) performance.
Specifically, the final test accuracy in CIL increased by 1.17 percentage points. This gain highlights the effectiveness of learning more transferable features, enabling FBNNs to adapt better to new tasks without extensive re-training of the entire network.
