Image to Music: Cross-Modal Melody Generation Through Image Captioning

Kaplan, Alper

Advances in machine learning in recent years have also been seen in computationally creative systems. Interest in machine-generated artifacts paved a way for creative models to evolve as such. But the earlier methods mostly explored a one domain approach and cross-modal learning has stayed relatively unexplored. Thus, the direct mapping between modalities for cross-modal creative models is not fully explored. This work proposes a novel methodology for generating symbolic music through images by directly mapping their features. A CNN encoder and deep stacked LSTM decoder are the base models as ...Daha fazlası

Status of Ilkhan in the socio-political organization of the Qashqai Tribe

Sohrabi, Hossein

This anthropological research is related to the Qashqai tribe, which lives in southwestern Iran, and apart from the urban and rural population, it has nearly 96,500 nomadic people. This research answers the question, could the Qashqais have the same solidarity, authority, and integrity without an Ilkhan from the Shahilu family? My claim is based on the fact that the main factor of Qashqai solidarity and empowerment in southern Iran, where the majority of the population is Tajik and non-Turkish, was the Ilkhans from the Shahilu family. And with the leadership of the Shahilu family, the Qashqais ...Daha fazlası
