Abstract

fetched live from OpenAlex

The development of ambient intelligence in the past decades calls for the smart environment that is able to respond to entities inside.The technology of contextawareness is a promising solution to this mobile distributed computing, not only in small personal electronic devices, but also in robotic systems.A prototype of context-aware assistive robotic system is designed and implemented in this thesis on the purpose of providing assistive services to the seniors and people with disabilities.The issue of context reasoning is extensively reviewed and researched.The particle filtering algorithm is improved in terms of proactive particle sampling, fuzzy based velocity estimation, and active observation selection, for the basic tasks of robotic tracking and following.The Monte Carlo partially observable Markov decision process is enhanced in terms of belief state augmentation, value function computation based on direct sampling, and non-greedy action execution, for the task of path planning.Experimental results are carried out to validate the feasibility and effectiveness of the proposed solutions.The prototyped robotic system can be further implemented on other potential applications for the aim of advanced service provision.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
