All ML projects which turned into a disaster in my career have a single common point:

🚨 I didn't understand the business context first, got over-excited about the tech, and jumped into coding too early.

When someone asks you for a model, always ask:

👉 why do you need it?
👉 what is your current solution (e.g. what is the baseline)?
👉 who is going to use the predictions and how?
👉 what is the impact of the model’s downtime or mistakes?
👉 which metrics do we care about?
Once you have your answers, back them up with a solid exploratory data analysis, and, when done, loop in the biz team again.

This is a critical moment as your results will translate into 3 potential outcomes:
💡 “Really? This is weird. Well, in this case, the ML model doesn’t make much sense anymore”. You are off the hook 🔴
💡 “Interesting. I guess we’ll have to change requirements/scope then.” Course-correct before moving forward 🟠
💡 “This is what I expected. Let’s go ahead”.🟢
Might seem silly, but skip the above and you are all set for failure.
Trust me, I learned it the hard way 😱

Also, always remember that the best model is no model.

Trump is gonna let the Mueller investigation end all on it's own. It's obvious. All the hysteria of the past 2 weeks about his supposed impending firing of Mueller was a distraction. He was never going to fire Mueller and he's not going to


Mueller's officially end his investigation all on his own and he's gonna say he found no evidence of Trump campaign/Russian collusion during the 2016 election.

Democrats & DNC Media are going to LITERALLY have nothing coherent to say in response to that.

Mueller's team was 100% partisan.

That's why it's brilliant. NOBODY will be able to claim this team of partisan Democrats didn't go the EXTRA 20 MILES looking for ANY evidence they could find of Trump campaign/Russian collusion during the 2016 election

They looked high.

They looked low.

They looked underneath every rock, behind every tree, into every bush.

And they found...NOTHING.

Those saying Mueller will file obstruction charges against Trump: laughable.

What documents did Trump tell the Mueller team it couldn't have? What witnesses were withheld and never interviewed?

THERE WEREN'T ANY.

Mueller got full 100% cooperation as the record will show.
