Trosolwyg
Mae gen i angerdd cryf am ymchwil sy'n gysylltiedig â rhyngweithio dynol-cyfrifiadurol, Ffactorau Dynol mewn delweddu, Rhyngweithio Data Dynol, addysg sy'n cael ei yrru gan dechnoleg, y Gwyddorau Cymdeithasol, Realiti Rhithwir, a Dimensiwn Cymdeithasol Technoleg. Credaf y gellir defnyddio datblygiad arloesol mewn technoleg mewn cynnyrch bob dydd sy'n darparu buddion i gymdeithas ers canrifoedd.
Fel myfyriwr israddedig, dilynais Gyfrifiadureg a Pheirianneg Meddalwedd yn Ysgol Cyfrifiadureg Prifysgol Colombo (UCSC), Sri Lanka. Graddiais ym mis Chwefror 2020 gyda gradd Baglor mewn Peirianneg Meddalwedd o Brifysgol Colombo, Sri Lanka. Dyfarnwyd fy mhrosiect ymchwil blwyddyn olaf fel yr ymchwil gorau ar gyfer y flwyddyn 2019. Ar ôl cwblhau fy astudiaethau israddedig, cefais y fraint o ymuno â staff UCSC a gweithio fel Hyfforddwr ac yna fel Darlithydd Cynorthwyol. Rwy'n bwriadu parhau â'm hawydd i ddatrys problemau cymdeithasol gan ddefnyddio defnydd moesegol a chydwybodol o dechnolegau cyfrifiadurol, data a gwybodaeth. Mae fy hobïau yn cyfansoddi / EmCeeing mewn cynadleddau a siarad cyhoeddus.
Mae fy mhrosiect ymchwil amlddisgyblaethol yn cynnwys delweddu gwybodaeth ynghylch y broblem newid hinsawdd fyd-eang gyda'r nod o sbarduno newid ymddygiad.

Ymchwil
Mae fy niddordebau ymchwil ym meysydd Rhyngweithio Dynol-Cyfrifiadurol, Ffactorau Dynol mewn delweddu, Rhyngweithio Data Dynol, Addysg sy'n cael ei yrru gan Dechnoleg, y Gwyddorau Cymdeithasol, Realiti Rhithwir, a Dimensiwn Cymdeithasol Technoleg. Mae'r diddordebau hyn wedi fy arwain at gynnal prosiectau rhyngddisgyblaethol sy'n cynnwys:
- Ymchwil Efelychu Hyfforddiant Peilot Drone - Ymchwil a wnaed wrth ddatblygu efelychiad drôn i hyfforddi peilotiaid drôn mewn amgylcheddau efelychiadol. Rhoddodd algorithmau gan ddefnyddio dull dysgu peiriant ganlyniadau gwell yn y model deinamig i ragweld y llwybr dros y model deinamig mathemategol.
- Llwyfan Ffrydio ac Argymell Cerddoriaeth Glywedol Hyblyg Ffynhonnell Agored ar gyfer Ceisiadau Realiti Amgen - Ar gyfer fy ymchwil israddedig blwyddyn olaf datblygais lwyfan cerddoriaeth symudol (Python, Android a Node.js) i gynhyrchu awgrymiadau chwilio awto-gwblhau, argymhellion personol, casglu dadansoddeg defnyddwyr, cerddoriaeth ffrwd, a chaneuon cache. Datblygais ategyn ar gyfer Amazon Alexa i chwarae cerddoriaeth o'r cais. Ymchwil yn y disgyblaethau Rhyngweithio Dynol-Cyfrifiadurol, systemau argymell, ac awgrymiadau chwilio awto-gwblhau (URL i'r sylfaen cod: https://github.com/helabeat).
- Treigl Polisi Yswiriant neu Rhagfynegiad Cadw – datblygais fodel i ganfod darfod neu gadw polisïau yswiriant (Keras a Weka).
- Prosesu Iaith Naturiol: Prosiect Canfod Lleferydd Casineb - Model canfod lleferydd casineb (yn Python) ar gyfer araith Sinhala a Saesneg yn Twitter. Cafwyd mwy na 60% o gywirdeb (atchweliad logistaidd, n-gram, a model word2vec).
- Cais Prosesu Delwedd ar gyfer Canfod Cwsg Gyrwyr – datblygais system ar gyfer canfod cwsg gan ddefnyddio Haar-rhaeadrau (Python).
- Canfod Twyll mewn Cyllid - Ceisiwyd hyfforddi a phrofi model gan ddefnyddio 4000 o werthoedd unigryw ar gyfer set ddata 'Data synthetig o system talu ariannol' Kaggle (mae'r canfyddiadau'n cynnwys bod XGBoost yn rhoi gwell canlyniadau dros KNN ac Autoencoders gyda chywirdeb prawf o 91% a gafwyd ar y set ddata).
- ARGAN - Defnyddio dysgu peiriannau a Realiti Estynedig i gyflwyno dyluniadau yn y diwydiant ffasiwn.
