Hello world and thanks for joining me. My name is Mohit Deshpande. In this course, we'll be learning all about probability theory and building a naive Bayes classifier that will be able to predict if our flight will land late or not. We're gonna be learning all about probability in this course. The first thing that I wanna do is introduce you to the concept of probability, if you're not already familiar with it and just to get all of the rotation out of the way. Then we're gonna move on to conditional probability and that's kinda the backbone of a lot of machine learning and data science algorithms that's working. Having a good idea of conditional probability will also help you out in a ton of other fields as well. Next we're gonna move on to Bayes' theorem which is gonna follow from a conditional probability. And Bayes' theorem, again, is a very fundamental statistical theorem that's used in all kinds of different applications. One application in particular is using it in a naive Bayes classifier. We're gonna build a naive Bayes classifier that we're gonna train it on a data set of flights and see if we can predict whether a flight will land late or not, given some set of features, such as how long the flight is in the air, the distance between the two airports, their departure time, the airline, and so on and so on. We can experiment with the groupings of features to see if we can get a really accurate classifier. We've been making courses since 2012 and we're super excited to have you onboard. Online courses are a great way to learn new skills and I take a lot of online courses myself. Zenva courses consist mainly of video lessons that we can watch and rewatch at your own pace as many tines as you want. We also have downloadable source code and project files and they contain everything that we build in the lessons. It's highly recommended that you code along with me. In my experience, that is the best way to learn something new, is to get your hands dirty. Lastly we've seen that students who get the most out of online courses are those that make a weekly plan and stick with it, depending, of course, on your own availability and learning style. Zenva, over the past six years, has taught all kinds of different topics on programming and game development to over 300,000 students across over a hundred courses. The skills that they learn in these courses are completely transferrable to other domains. In fact, some of the students that have used, have taken these courses, have used the skills to advance their own careers, to start a company or to publish their own content from the skills that they've learned.
