You are looking to get into Machine Learning? You most cert…

The path that I took wasn't the most optimal way to get a good grip on Machine Learning because...

when I started out, I knew nobody that worked or had knowledge of Data Science which made me try all sorts of different things that were not actually necessary.

I studied C programming as my first language during my freshman year in college. And before the start of my second year, I started learning python just because I knew C is not the way to go.
I learned it out of curiosity and I had no idea about Machine Learning at this point.

I did not learn python by courses but by books. I'll link all the resources at the end.
The approach I took was just to make the same kind of programs I made in C but just replacing the syntax with that of python and practised those.
Already knowing a language made it easier.

For Machine Learning, the first thing that I did was to join Andrew NG's course which really hit it off for me
I didn't have to have any idea about Machine Learning for the course. I completed that in almost a month and it gave me a good intuition of things and the flow of ML.

Then I thought of implementing those concepts through python
But after a lot of tries, I wasn't really able to do it. Because I was constantly encountering a lot of stuff things in code that I wasn't really aware of.

Even loading the CSV data seemed like a hard task.

What I was lacking was the basic python and ML libraries. So I started focusing on learning those.

The absolute necessary ones were
🔸Numpy
🔸Pandas
🔸Matplotlib
🔸Seaborn
🔸SciKit Learn
🔸Os (an important built-in package).

There were two really good udemy courses that helped me with the library portion and implementing the algorithms through Sci-Kit learn with dummy datasets.

The practice of the taught concepts multiple times was necessary, I did that as much as I could and also read blogs on them

Everything that I did from there on was from Kaggle. It is a platform that's closest to exposing what real-life problems may look like.

Different people solve the same problem differently and you read a lot of other people's code. From there on that's what kept me growing.

Things I learned from Kaggle:

🔹Exploration and visualization of data
🔹How to approach a new problem
🔹Better code structure for implementing a machine learning solution

You don't have to be an absolute grandmaster of kaggle but plenty practice and patience is needed.

Then I just picked up some common projects and implemented them, mostly from kaggle. Like,

▪ Titanic Survival
▪ Spam Classification
▪ Movies Recommendation
▪ Boston House Pricing
▪ Churn Prediction

You'll kind of know your way from there, moving to harder problems slowly.

Don't overthink about maths more than it is necessary. You can always learn the mathematical concepts that you may be missing as you go.

Learning the maths behind will keep things interesting if you won't enjoy that you will get bored pretty quickly.

Finally, it can get quite overwhelming at times, make sure to take one step at a time. Don't focus on how far ahead other people are focus on how much you'll grow from here.

And you are NOT too old or too young for this stuff
Look at these two guys @svpino @PrasoonPratham !

Have a happy journey in this wonderful domain!
