The slides present a high-level knowledge of the accurate prediction of solar irradiance power from a particular location using hybrid machine learning models viz Stacked Stateless/ Stateful GRU, LSTM and Autoencoders, which can be proved to be viable if applied to prior installation of solar photovoltaic cells in a particular area. The project tries to save the cost prior to the installation of solar panels by accurately predicting the appropriate location from where power can be elicited to meet the desired electric power required for running industries. The analysis of the hybrid machine learning models is done to determine which model is best suited for prediction by feeding them with data such as geometrical coordinates, solar parameter like GHI and weather parameters like temperature and wind speed etc.

In human society there exists colour based variation. In many ethnicities, colour variation is associated with beauty and attractiveness prevails in society. In dominant endogamous societies within an ethnicity, these characteristics are preserved and highly prioritized as markers of physical attractiveness in that ethnicity. Such dominant groups within an ethnicity dominate others, among other things, in terms of public portrayal, places, spaces and various opportunities on the basis of characteristics largely possessed and hence prized by dominant groups and are held up as aspiration goals to the rest. People who have fairer skin tone as compared to the darker skin tone tries to dominate other in terms of public portrayal. These public portrayals are clearly seen in the case of visual mass media like cinema and advertisement. This paper explores whether such skin colour tone based bias exists in case of Bangali ethnicity. The skin tone of heroes and heroines of popular Bangla films produced in West Bengal was taken as a proxy to explore the nature of skin colour tone based bias (if any), in case of the Bangla mother tongue population, the 5 th largest mother tongue population in the world. We found that the heroes and heroines have significantly lighter skin tones than other males and females of same ethnicity who are portrayed in a film. The results suggest that there exists significant skin colour based bias in the selection of heroes and heroines in Bangla films.
