The dataset consists of multiple flight records with key features, including airline names, journey durations, number of stopovers, departure and arrival times, and routes. These features serve as independent variables, influencing the final price of the tickets.
The dataset is crucial for training the models, allowing them to learn patterns and relationships between flight attributes and ticket prices. Such a model can be instrumental for travel agencies, airlines, and travelers to estimate flight costs and plan bookings efficiently.
For performance optimization, I integrated Intel's oneAPI, an open, unified programming model that enables developers to write code that runs seamlessly on multiple hardware types, including CPUs, GPUs, and FPGAs.
Using oneAPI’s oneDAL library, I optimized the Random Forest, Ridge Regression and Scikit-Learn to take advantage of hardware accelerators, leading to faster training and prediction times. This enhancement allows the model to provide real-time predictions with high efficiency, even on large datasets.
