‫Congratulations.
‫You just got hired at Keiko Corp..
‫They're the latest Silicon Valley startup to hit the scene.
‫They help analyze data of large companies and consult on what companies should do with their data.
‫They do autonomous vehicles, security cameras.
‫They have an online dating app, a website.
‫They even have drones.
‫And they also offer their services like Amazon, to other big companies or startups.
‫And you just got hired.
‫Awesome.
‫Wait, what is your role?
‫Well, you're the new machine learning and data science expert.
‫Well, this is a little awkward because you don't really know anything about that, do you?
‫Maybe a little bit, maybe you've heard it in the news, but this is going to be awkward because it's
‫too late.
‫You're already hired and people want you working right away.
‫So you entered the office and.
‫Oh, there's your boss right there.
‫This guy over here with the perfect hair.
‫That's Bruno.
‫He just got promoted, and he's really excited to make an impact with KeyCorp in their data division.
‫And he just hired you to lead some of their initiatives.
‫Now.
‫He seems nice on the surface, but I have a feeling that he's going to be a tough cookie to work with.
‫But you know what?
‫We'll get through this.
‫Now, if your memory is fuzzy of how you ended up here at Cake Corp, let's not worry about that.
‫It's your first day on the job.
‫All you know is that you're the new machine learning and data science expert now because this is your
‫first day.
‫As you do, you go out for lunch with your coworkers and luckily they don't ask you too many questions
‫and they seem to like you.
‫They seem to be nice.
‫But then during lunch comes the question.
‫Hey, we've heard about this machine learning thing, and Bruno said that you're the expert on the topic
‫and we're excited to have you on the team.
‫But what is machine learning?
‫And you think to yourself, Oh, boy, what should I say here?
‫Well, you know what, guys?
‫I have to go back to work.
‫Don't have much time.
‫I'll explain it to you tomorrow.
‫So you run away.
‫Still confused how you got here.
‫But luckily the day ends with you not revealing that you know absolutely nothing and you have no idea
‫how you just got hired.
‫You survived the first day, but we have a problem, right?
‫Tomorrow you have to go into work and you're going to have to explain this to your colleagues.
‫Hopefully can survive throughout the next couple of weeks and let people know that you're not an impostor.
‫But, hmm.
‫What should we do here?
‫Well, luckily for you, you remember your old childhood friends.
‫Their name?
‫Andre and Daniel.
‫Look how cute they were as a baby.
‫You call them up and you say, hey, somehow I landed this job in Silicon Valley.
‫It's really well paid, but I have no idea what I'm talking about.
‫And luckily for you, they know.
‫So they're going to help you throughout this journey to make sure that Bruno doesn't fire you and you
‫impress all your colleagues.
‫What we're going to do is each day at work, you're going to get some tasks and then you're going to
‫go back home.
‫And Andre and Daniel are going to help you so that.
‫Well, you don't get fired.
‫So.
‫Here we are, all of us at home trying to decide how we're going to tackle this first problem.
‫That is what is machine learning.
‫We have to go into work tomorrow and explain it to our colleagues.
‫Let's get to it.
‫What is machine learning?
