    Sammanfattning : Predicting human emotions through facial expression, particularly in relation to medication field such as clinical trial settings, has garnered scientific interest in recent years due to significant understanding of the impact of treatment on emotions and social functioning. This thesis aims to improve performance of a FER model using large scale of synthetic data. LÄS MER

  3. 2. Are Distributed Representations in Neural Networks More Robust Against Malicious Fooling Attacks

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Nida Sardar; Sundas Khan; [2023]
    Nyckelord :Adversarial attacks; Information Smearedness; Artificial Neural Networks; Information Relay; Dropout; Fast Gradient Sign Method;

    Sammanfattning : A plethora of data from sources like IoT, social websites, health, business, and many more have revolutionized the digital world in recent years. To make effective use of data for any sort of analysis, prediction, or automation of applications, the demand for machine learning and artificial intelligence has grown over time. LÄS MER

  4. 3. The brain in conversation: Mapping the neural correlates of turn-taking, production, and comprehension using fMRI

    Magister-uppsats, Stockholms universitet/Institutionen för lingvistik

    Författare :Caroline Arvidsson; [2022]
    Nyckelord :turn-taking; production; comprehension; conversation; fMRI; speech planning; turtagning; produktion; förståelse; konversation; fMRI; språkplanering;

    Sammanfattning : Conversation is the primary mode of language use. A key feature of conversation is turn-taking, during which interlocutors rapidly switch between speaker and listener roles without conscious effort. LÄS MER

  5. 4. Facial recognition techniques comparison for in-field applications : Database setup and environmental influence of the access control

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :Gustav Norvik; [2022]
    Nyckelord :facial recognition; deep learning; machine learning; computer vision; image processing; artificial intelligence;

    Sammanfattning : A currently ongoing project at Stanley Security is to develop a facial recognition system as access control system to prevent theft of heavy vehicles for terrorist purposes. As of today, there are several providers of facial recognition techniques and the spectrum ranges from multi dollar licenses to easy access open source. LÄS MER

  7. 5. Frontal Alpha Asymmetry scores in threatening and non-threatening conditions

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Gratsia Johansson; [2022]
    Nyckelord :frontal alpha asymmetry; threat; facial processing; state-based FAA;

    Sammanfattning : The current paper examined the relationship between frontal alpha asymmetry (FAA) and threatening face stimuli. Participants were presented with threatening faces, and this was compared to non-threatening (neutral) faces, on the assumption that the threatening faces would trigger a withdrawal motivation and a corresponding decrease in state FAA scores.
