Controlled Evaluation of Graph and Multimodal Augmentation in RAG for Document Question Answering
Sokipriala Jonah, Opeoluwa Akinseloyin, Michael Ajao-Olarinoye +1
Graph and multimodal extensions to retrieval-augmented generation (RAG) are often evaluated end to end, making it difficult to isolate whether gains arise from retrieval, prompt-si…
LLMs for Agentic Home Energy Management
Sokipriala Jonah, Queen Moses, Abiola Babatunde +2
Home Energy Management Systems (HEMS) can reduce residential electricity costs, but many require users to express everyday preferences as technical constraints. This paper presents…
Empirical and Statistical Characterisation of 28 GHz mmWave Propagation in Office Environments
Ayodeji Bolanle Balogun, Sokipriala Jonah
Millimeter wave (mmWave) technology at 28 GHz is vital for beyond-5G systems, but indoor deployment remains challenging due to limited statistical evidence on propagation. This stu…
Adaptive Scheduling: A Reinforcement Learning Whittle Index Approach for Wireless Sensor Networks
Sokipriala Jonah, Seong Ki Yoo, Saurav Sthapit
We propose a reinforcement learning based scheduling framework for Restless Multi-Armed Bandit (RMAB) problems, centred on a Whittle Index Q-Learning policy with Upper Confidence B…
