Item Open Access Evaluation of conversational agents: understanding culture, context and environment in emotion detection(2022) Teye, Martha T.; Missah, Yaw Marfo; Ahene, Emmanuel; Frimpong, TwumValuable decisions and highly prioritized analysis now depend on applications such as facial biometrics, social media photo tagging, and human robots interactions. However, the ability to successfully deploy such applications is based on their efficiencies on tested use cases taking into consideration possible edge cases. Over the years, lots of generalized solutions have been implemented to mimic human emotions including sarcasm. However, factors such as geographical location or cultural difference have not been explored fully amidst its relevance in resolving ethical issues and improving conversational AI (Artificial Intelligence). In this paper, we seek to address the potential challenges in the usage of conversational AI within Black African society. We develop an emotion prediction model with accuracies ranging between 85% and 96%. Our model combines both speech and image data to detect the seven basic emotions with a focus on also identifying sarcasm. It uses 3-layers of the Convolutional Neural Network in addition to a new Audio-Frame Mean Expression (AFME) algorithm and focuses on model pre-processing and post-processing stages. In the end, our proposed solution contributes to maintaining the credibility of an emotion recognition system in conversational AIs.Item Open Access Breathing artifacts of urban bioblimatic layers for post‐anthropocene urban environment(2021) Davidová, MarieThis article seeks the qualitative synthesis of schools of thought from extreme climate regions that could support urban biodiversity and climate change adaptation through architectural design. It proposes that climate comfort and biodiversity are closely related. This article suggests a possible systemic urban metabolism within a built environment that can support a transition to post‐Anthropocene, where humans and other species live together in synergy. This article exemplifies and seeks systemic relations and reflections of gathered field studies documentation of case studies of breathing walls, envelopes, and screens generating bioclimatic layers in the cultural landscape, selected for their penetrability and performance. The samples from diverse study journeys that were codesigned through vernacular cultures and the author’s research by design speculations on the responsive screen ‘Ray’ are investigated and speculated upon through gigamapping (visual complexity mapping). This gigamapping is not to present any hard data model but to relate, inform and speculate on the investigated field that is grounded in research by design on cross‐species coliving. This is approached through possible architectures and architectural and urban design parasites, transitioning towards synergetic landscapes of our envisioned colived and cocreated futures.Item Open Access Constructing platform capitalism : inspecting the political techno-economy of Building Information Modelling(2022) Braun, Kathrin; Kropp, Cordula; Boeva, YanaItem Open Access Co-De|GT: the gamification and tokenisation of more-than-human qualities and values(2022) Davidová, Marie; Sharma, Shanu; McMeel, Dermott; Loizides, Fernando
