A step-by-step guide to starting with Machine Learning. (For beginners looking to get on it right away.)

Table of Contents:

1. Where do I put the code?
2. Manipulating data
3. Let me see those charts
4. Decision Trees
5. Tying everything together
6. Our very first project

🧵👇

0⃣ Requirements to go through this guide:

▫️Python 🐍
▫️Wanting to make a difference.

To finish this tutorial you do not need any of the following:

▫️Math
▫️Degrees
▫️(Irrelevant) years of experience
▫️Superpowers

I promise; this is for you.

Let's get started!

👇

1⃣ Where do I put the code?

Jupyter is gonna be your code editor. Notebooks are a fantastic way to code, experiment, and communicate your results.

Take a look at @CoreyMSchafer's fantastic 30-minute tutorial on Jupyter Notebooks.

👇

@joejamesusa

2⃣ Manipulating data

The Pandas library is a one-stop-shop for this.

"10 minutes to pandas" is an excellent tutorial that will get you started on the basics really quick: pandas.pydata.org/pandas-docs/st…

@joejamesusa's YouTube tutorial is very good:

👇

@blondiebytes

3⃣ Let me see those charts

"Photo or it didn't happen."

Let's learn data visualization and how to showcase the work you are doing.

Kaggle's tutorial is a fantastic start: kaggle.com/learn/data-vis…

@blondiebytes's YouTube 6-minute tutorial on matplotlib is also great.

👇

@random_forests

4⃣ Decision Trees

This is probably the simplest algorithm that will get you started.

Here is a great tutorial: hackerearth.com/practice/machi…

You should also watch @random_forests' video where he builds a decision tree from scratch:

@dan_s_becker

5⃣ Tying everything together

It's time to go through an end-to-end tutorial that will put everything together for you.

Look at @dan_s_becker's Intro to Machine Learning tutorial. It will be quick and to the point.

kaggle.com/learn/intro-to…

👇

6⃣ Our very first project

Who doesn't know about the Titanic? 🚢

Dan's tutorial from the previous step ends with this exercise.

You can find it in Kaggle: kaggle.com/c/titanic/data. Everything you need to get started and to finish your first Machine Learning project!

👇

If you are a beginner and follow this guide, you should be able to overcome the hardest challenge in a Machine Learning journey: getting started!

All of the resources here are free. All of them are well taught and to the point.

But, what are you still doing here? Let's do this!

Here are 20 fundamental questions that you need to ace before getting a Machine Learning job.

Almost every company will ask these to weed out non-prepared candidates. You don't want to show up unless you are comfortable having a discussion about all of these.

🧵👇

Of course, this is not an exhaustive list. There are many more topics and concepts you should master before applying for a job.

But hopefully, these will give you an idea of where you stand today.

🏃‍♂️Let's get started!

👇

▫️ Warming up ▫️

1. Explain the difference between Supervised and Unsupervised methods.

2. What's your favorite algorithm? Can you explain how it works?

3. Given a specific dataset, how do you decide which is the best algorithm to use?

It took me 4 years to complete my Master's while I was working full time (2015 - 2019).

It's a Master of Science in Computer Science with a Machine Learning Specialization.

Here are all courses I had to complete to finish the program: 🧵👇

For the Machine Learning Specialization, I needed 15 hours that I distributed across the following courses:

1. Machine Learning
2. Computer Vision
3. Reinforcement Learning
4. Intro to Graduate Algorithms
5. Machine Learning for Trading

👇

To complete the program, I needed another 15 hours (but I finished 18):

6. Database Systems Concepts and Design
7. Software Development Process
8. Software Architecture and Design
9. Human-Computer Interaction
10. Advanced Operating Systems
11. Software Analysis and Testing

Artificial Intelligence can be a bitch.

Here are 6 high-profile projects that have miserably failed and have made the respective companies look really foolish:

🧵👇

1⃣ Back in 2015, a software engineer reported that Google Photos was classifying his black friends as gorillas.

The algorithm powering the service was unable to properly classify some people of color 🤦!

Here is the story: theverge.com/2018/1/12/1688…

👇

2⃣ Back in 2016, Amazon had to scrap it's AI recruiting tool because it discovered that the system taught itself that male 👨 candidates were preferable, and penalized every resume that pointed to a female 👩 candidate.

Here is the story: reuters.com/article/us-ama…

Got asked a ton of questions about Machine Learning!

I decided to build a short FAQ to help you move forward.

Here are my answers to the 10 most frequently asked questions about getting into Machine Learning: 🧵👇

1⃣ Do I need Probabilities / Statistics / Linear Algebra to get started?

All of these help tremendously, especially if you want to understand how the algorithms work.

But they aren't a hard requirement to start applying some of the algorithms.

👇

2⃣ How relevant is a Ph.D. or MS degree to get a job?

Companies are currently asking for degrees to weed out people that apply to jobs prematurely.

But degrees aren't a requirement most of the time. Your skillset is the most important factor.

One of the best steps I’ve taken as a Software Engineer has been to get into Machine Learning.

If you are looking for what's next in your career, here are some pointers to get you started: 🧵👇

I always answer “what would you recommend next?” with "Machine Learning."

Here is why:

1⃣ Not only we are barely touching the surface of how Machine Learning will transform our lives in the next 10 years, but the need for qualified professionals will continue to rise.

👇

2⃣ As of today, Machine Learning is one of the fields that pay the most money, at least in the United States.

3⃣ There's huge demand, but there aren't many people competing in the market which opens many opportunities.

I've been in leadership positions for over a decade, and during that time, I've helped sell millions of dollars in software services.

Here are some of the things that I've learned about charging money for your skills. 🧵👇

First, we need to talk about hourly pricing.

Everyone will tell you to get away from hourly pricing and more into value-based pricing.

I agree.

But here is the thing: value-based pricing doesn't work a lot of the time. Hourly pricing always works.

👇

A lot of clients don't fall for the "I'm increasing your sales by $50,000 a year, so my website is worth $20,000" strategy.

That $50,000 is —most of the time— a bad guesstimate. You can't pretend to understand a business that well in a few days. And clients will call BS.
