Combining EEG and NLP Features for Predicting Students' Lecture Comprehension using Ensemble Classification

no code implementations18 Nov 2023 Phantharach Natnithikarat, Theerawit Wilaiprasitporn, Supavit Kongwudhikunakorn

In this work, we propose a classification framework for predicting students' lecture comprehension in two tasks: (i) students' confusion after listening to the simulated lecture and (ii) the correctness of students' responses to the post-lecture assessment.

PACMAN: a framework for pulse oximeter digit detection and reading in a low-resource setting

no code implementations9 Dec 2022 Chiraphat Boonnag, Wanumaidah Saengmolee, Narongrid Seesawad, Amrest Chinkamol, Saendee Rattanasomrerk, Kanyakorn Veerakanjana, Kamonwan Thanontip, Warissara Limpornchitwilai, Piyalitt Ittichaiwong, Theerawit Wilaiprasitporn

In light of the COVID-19 pandemic, patients were required to manually input their daily oxygen saturation (SpO2) and pulse rate (PR) values into a health monitoring system-unfortunately, such a process trend to be an error in typing.

SleepPoseNet: Multi-View Learning for Sleep Postural Transition Recognition Using UWB

1 code implementation2 May 2020 Maytus Piriyajitakonkij, Patchanon Warin, Payongkit Lakhan, Pitsharponrn Leelaarporn, Theerasarn Pianpanit, Nakorn Kumchaiseemak, Supasorn Suwajanakorn, Nattee Niparnan, Subhas Chandra Mukhopadhyay, Theerawit Wilaiprasitporn

Recognizing movements during sleep is crucial for the monitoring of patients with sleep disorders, and the utilization of ultra-wideband (UWB) radar for the classification of human sleep postures has not been explored widely.

MetaSleepLearner: A Pilot Study on Fast Adaptation of Bio-signals-Based Sleep Stage Classifier to New Individual Subject Using Meta-Learning

1 code implementation8 Apr 2020 Nannapas Banluesombatkul, Pichayoot Ouppaphan, Pitshaporn Leelaarporn, Payongkit Lakhan, Busarakum Chaitusaney, Nattapong Jaimchariyatam, Ekapol Chuangsuwanich, Wei Chen, Huy Phan, Nat Dilokthanakul, Theerawit Wilaiprasitporn

This is the first work that investigated a non-conventional pre-training method, MAML, resulting in a possibility for human-machine collaboration in sleep stage classification and easing the burden of the clinicians in labelling the sleep stages through only several epochs rather than an entire recording.

Towards Asynchronous Motor Imagery-Based Brain-Computer Interfaces: a joint training scheme using deep learning

no code implementations31 Aug 2018 Patcharin Cheng, Phairot Autthasan, Boriwat Pijarana, Ekapol Chuangsuwanich, Theerawit Wilaiprasitporn

The focus is mainly on three types of brain responses: non-imagery EEG (\textit{background EEG}), (\textit{pure imagery}) EEG, and EEG during the transitional period between background EEG and pure imagery (\textit{transitional imagery}).
