Single-Pass Uncertainty Heads for Claim-Level Hallucination Detection in Persian Medical Language Models
Mehrdad Ghassabi, Pedram Rostami, Hamidreza Baradaran Kashani +2
Hallucination detection is particularly important for medical language models, but repeated-sampling approaches are computationally expensive. A faster alternative is a single-pass…
Gaokerena: A Small Persian Medical Language Model Family
Mehrdad Ghassabi, Hamidreza Baradaran Kashani, Pedram Rostami +5
Persian medical natural language processing remains limited by the scarcity of domain-specific resources and insufficient public characterization of their coverage and quality. We…
Backtranslation Augmented Direct Preference Optimization for Neural Machine Translation
Mehrdad Ghassabi, Spehr Rajabi, Hamidreza Baradaran Kashani +3
Contemporary neural machine translation (NMT) systems are almost exclusively built by training on supervised parallel data. Despite the tremendous progress achieved, these systems…
Enhancing Reasoning Skills in Small Persian Medical Language Models Can Outperform Large-Scale Data Training
Mehrdad Ghassabi, Sadra Hakim, Hamidreza Baradaran Kashani +1
Enhancing reasoning capabilities in small language models is critical for specialized applications such as medical question answering, particularly in underrepresented languages li…
Leveraging Online Data to Enhance Medical Knowledge in a Small Persian Language Model
Mehrdad Ghassabi, Pedram Rostami, Hamidreza Baradaran Kashani +3
The rapid advancement of language models has demonstrated the potential of artificial intelligence in the healthcare industry. However, small language models struggle with speciali…
Speech Enhancement via Deep Spectrum Image Translation Network
Hamidreza Baradaran Kashani, Ata Jodeiri, Mohammad Mohsen Goodarzi +1
Quality and intelligibility of speech signals are degraded under additive background noise which is a critical problem for hearing aid and cochlear implant users. Motivated to addr…
Image to Image Translation based on Convolutional Neural Network Approach for Speech Declipping
Hamidreza Baradaran Kashani, Ata Jodeiri, Mohammad Mohsen Goodarzi +1
Clipping, as a current nonlinear distortion, often occurs due to the limited dynamic range of audio recorders. It degrades the speech quality and intelligibility and adversely affe…
