Amnesia: A Stealthy Replay Attack on Continual Learning Dreams
Ahmed Sharshar, Naveen Kumar Kummari, Mohsen Guizani
Continual learning (CL) models often use experience replay to reduce catastrophic forgetting, but their robustness to replay sampling interference remains underexplored. Existing C…
ChatENV: An Interactive Vision-Language Model for Sensor-Guided Environmental Monitoring and Scenario Simulation
Hosam Elgendy, Ahmed Sharshar, Ahmed Aboeitta +1
Understanding environmental changes from remote sensing imagery is vital for climate resilience, urban planning, and ecosystem monitoring. Yet, current vision language models (VLMs…
Constraint-Driven Warm-Freeze for Efficient Transfer Learning in Photovoltaic Systems
Yasmeen Saeed, Ahmed Sharshar, Mohsen Guizani
Detecting cyberattacks in photovoltaic (PV) monitoring and MPPT control signals requires models that are robust to bias, drift, and transient spikes, yet lightweight enough for res…
Harm or Humor: A Multimodal, Multilingual Benchmark for Overt and Covert Harmful Humor
Ahmed Sharshar, Hosam Elgendy, Saad El Dine Ahmed +2
Dark humor often relies on subtle cultural nuances and implicit cues that require contextual reasoning to interpret, posing safety challenges that current static benchmarks fail to…
Bridging ASR and LLMs for Dysarthric Speech Recognition: Benchmarking Self-Supervised and Generative Approaches
Ahmed Aboeitta, Ahmed Sharshar, Youssef Nafea +1
Speech Recognition (ASR) due to phoneme distortions and high variability. While self-supervised ASR models like Wav2Vec, HuBERT, and Whisper have shown promise, their effectiveness…
Not Only Grey Matter: OmniBrain for Robust Multimodal Classification of Alzheimer's Disease
Ahmed Sharshar, Yasser Ashraf, Tameem Bakr +4
Alzheimer's disease affects over 55 million people worldwide and is projected to more than double by 2050, necessitating rapid, accurate, and scalable diagnostics. However, existin…
