Let's look at a few application cases for data science.
Amazon: Amazon uses a customized recommendation system to raise consumer happiness. In this, predictive analytics are essential. To provide more product recommendations, Amazon looks at a user's past purchases.
Spotify: For personalised music recommendations, Spotify employs data science. Spotify generated predictions regarding the 2013 Grammy Award winners based on the music its users are listening to. Six predictions were made, and four were correct.
Uber: To enhance user experience and obtain deeper insights, Uber leverages big data. Due to its huge database of drivers, it can suggest the ideal driver to consumers. According to how long it takes to get there, Uber charges its customers. Many algorithms are in favor of this.
