Trosolwyg
Rwy'n Ddarlithydd (athro cynorthwyol) mewn Cyfrifiadureg a Gwybodeg ym Mhrifysgol Caerdydd, y DU, sy'n arbenigo mewn AI, dysgu peirianyddol ar gyfer Ceisiadau Ffactorau Dynol. Yn y gorffennol rwyf wedi gweithio mewn amrywiol brosiectau ymchwil rhyngddisgyblaethol, gan gynnwys dosbarthu cof, canfod twyll ac efelychiadau torfol. Mae llawer o'm gwaith wedi canolbwyntio ar ddatblygu dulliau ar gyfer dadansoddi a dosbarthu data cyfres amser.
Ar hyn o bryd mae gen i ddiddordeb mewn prosesu fideos amlfoddol. Mynegiant yr wyneb (micro) - cydnabyddiaeth emosiwn, dadansoddi testun, dadansoddi llais ym maes canfod twyll gan ddefnyddio dysgu peiriant. Mae gen i ddiddordeb mewn ymgorffori nodweddion a dynnwyd o'r dulliau hyn gyda ffactorau seicolegol eraill yn ogystal â nodweddion o olrhain llygaid.
Yn fras, mae gen i ddiddordeb mewn gwyddoniaeth gynhwysfawr (cyfrifiadurol) (niwro) a sut y gall cyfrifiadureg helpu ymddygiad enghreifftiol a phrosesau gwybyddol. Bydd y ddealltwriaeth hon yn ein helpu i adeiladu ceisiadau newydd cyffrous.

Mae gen i ddiddordeb mewn cymhwyso AI, technegau dysgu peirianyddol i adeiladu cymwyseddau ffactorau dynol, gan ganolbwyntio ar feysydd fel sylw, amldasgio a gwneud penderfyniadau. Rwy'n defnyddio mesuriadau ffisiolegol fel syllu, dilation disgyblion, eeg ar y cyd â fideo, testun a dadansoddiad llais i astudio'r meysydd uchod.
Mae gen i ddiddordeb mewn ymddygiadau o dan sefyllfaoedd llawn straen, a sut i ddatblygu technolegau i helpu pobl i wneud penderfyniadau a pherfomance tasgau.
Mae gen i arbenigedd mewn dadansoddi a dosbarthu data niwroddelweddu/cyfres amser.
Addysgu
Meddwl Cyfrifiannol CM6114 / CM6614: Nod y cwrs yw galluogi myfyrwyr i drosi problemau yn y byd go iawn yn god cyfrifiadur. Mae'r ffocws ar ddatblygu'r gallu i gymhwyso cysyniadau craidd trwy ysgrifennu cod sy'n datrys problemau sylfaenol, gan osod y sylfaen ar gyfer codio cynhyrchiol mewn modiwlau diweddarach. Ar ôl cwblhau'r modiwl hwn yn llwyddiannus, disgwylir i fyfyrwyr fynd i'r afael â phroblemau mewn ffordd gyfrifiadurol trwy feddwl rhesymegol, diwygio, tynnu sylw, dadelfennu a chynrychiolaeth ddata briodol. Bydd myfyrwyr hefyd yn datblygu dealltwriaeth sylfaenol o'r algorithmau datrys problemau mwyaf poblogaidd (chwilio, didoli, llwybro, dyrannu adnoddau), eu disgrifio mewn ffordd wyddonol a gwerthuso eu cymhlethdod. Yn olaf, byddant yn ymdrin â sut mae gwybodaeth yn cael ei storio a'i chyrchu mewn cyfrifiadur a byddant yn gallu cyfieithu ar draws gwahanol systemau rhifau.
