Why Fake ? Unveiling the Semantic Vocabulary of Deepfake Detectors

Vazgken Vanian, Alexandros Doumanoglou, Dimitris Zarpalas

Deepfake (DF) technology poses a significant threat to information integrity, driving the need for robust detection methods. Most DF detectors only consider predicting a binary label for whether the input is real or fake, lacking the justification required for real-world applicat…

Compressing What Matters: Neuron Importance Meets Data-Aware Low Rank Approximation for Language Model Compression

Athanasios Ntovas, Alexandros Doumanoglou, Petros Drakoulis, Dimitris Zarpalas

To excel at their domain large language models are comprised of billions of parameters. Yet this comes at the cost of huge memory requirements restricting their applicability in resource-constrained environments. To address the problem of neural network (NN) compression Singular…
