Ans 1.
Introduction
In the contemporary age of digitalization, the aviation industry, like many others, stands at the intersection of rapid technological evolution and ever-increasing customer expectations. Low-cost airlines, which primarily focus on reducing operational expenses to offer competitive fares, operate under thin profit margins. This makes the efficient use of data and analytics crucial for success. With the deluge of data, ranging from customer preferences to flight operations, airlines have a
2. Alset is a multi-national top end electric vehicle manufacturer and a market leader in providing autonomous driving features. No other car manufacturer in the world is anywhere near Alset in the autonomous driving space. Being at the forefront comes with its challenges.
Alset’s top management heard about its software not being able to differentiate between 2-wheelers, i.e., motorcycles and bicycles. Which caused an erroneous speed estimation of those 2-wheelers and led to some non-fatal accidents. The organization wants to avoid this. For which, it needs a lot of data to train the model. But it’s not storing any data from their cars. Some of the users agreed to share the image/video data from their cars but Alset doesn’t have a data collection or storage or processing methodology in place because all the processing thus far has been on the on-board units (OBUs). To solve this the firm consults and gives you the responsibility to design their pipeline. They don’t have any historical data on any kind of 2-wheelers.
How do you approach this problem holistically using both big data and business analytics concepts? Explain the big data component for storage and processing, and analytics component of approaching this use case and what would you do in each of the stages. Goal is to help company collect, store, process data and better predict and classify between different kinds of 2-wheelers. (10 Marks)
