Student perspectives on AI‐supported formative assessment in pharmacology
British Journal of Clinical Pharmacology, EarlyView.Abstract Aims High‐quality feedback is crucial for helping medical students understand and apply core concepts of pharmacology, yet personalized feedback is resource‐intensive to produce. Artificial intelligence (AI) offers a potential solution, but little is known about students' perspectives on AI‐generated feedback.

A Codebook-Adaptive Feedback Algorithm for Cellular-Based Positioning
IEEE Access, 2018 To ensure positioning accuracy and speed of cellular-based human position acquisition for location-based service in a smart system, channel state information between the base station (BS) and user equipment (UE) is required at the BS to acquire the ...

British Educational Research Journal, EarlyView.Abstract With growing attention to student agency in academic and policy discourse, international education has become a prominent context for examining how students navigate new cultural, academic, linguistic and social environments. However, much of this discussion attributes student agency to the ‘international’ aspect, while overlooking the ...

Constrained VQ codebook design for noisy channels
Electronics Letters, 2001 A codebook design approach for constrained vector quantisation using the Hadamard transform of channel transition probabilities is proposed. It is examined for quantisation of Gauss-Markov sources over channels with memory and compared with the generalised Lloyd algorithm.

Source Quantization and Coding over Noisy Channel Analysis
MathematicsRecently, lossy source coding based on linear block code has been designed using the duality principle, i.e., the channel decoding algorithm is employed to realize the lossy source coding. However, the quantization structure has not been analyzed in this
