Memory Bank Compression for Continual Adaptation of Large Language Models

Thomas Katraouras, Dimitrios Rafailidis

The 41st ACM/SIGAPP Symposium on Applied Computing, 2026

Proposed MBC, a memory-augmented continual learning model that reduces the memory bank footprint by 99.7% by compressing stored representations through codebook optimization and online resetting mechanisms. Improved QA accuracy by 11.84% (EM) and 12.99% (F1) over state-of-the-art baselines, enabling efficient knowledge updates in LLMs without catastrophic forgetting.

Pruning Overparameterized Multi-Task Networks for Degraded Web Image Restoration

Thomas Katraouras, Dimitrios Rafailidis

IEEE/WIC International Conference on Web Intelligence and Intelligent Agent Technology, 2025

Proposed MIR-L, a compressed multi-task image restoration model that achieves 90% reduction in trainable parameters through lottery tickets while maintaining or exceeding state-of-the-art performance on deraining, dehazing, and denoising tasks.

Projects

Developed a LSTM model for Bitcoin price forecasting that integrates X (Twitter) sentiment analysis, achieving 15.88% reduction in RMSE, 15.49% reduction in MAE, and 11.71% reduction in MAPE compared to price-only baseline.

Developed a text classification system for news articles using CNNs with custom word embeddings and fine-tuned Transformer models (DistilBERT) to improve accuracy to 78.9%.

Built a recommender system for Steam games using content-based and collaborative filtering (Cosine Similarity, SVD), featuring a custom review-weighted algorithm, an experimental Neural Network with embeddings, and an interactive GUI.
