@jaimestein Love that shirt!

[Casey Rovinelli @caseyrovinelli]

Wrong on so many levels. Grok AI is wild.

@chris_j_paxton Did I see that right….straight from the toilet to the shower with the same rag? Eeek.

[Casey Rovinelli @caseyrovinelli]

@jaimestein @voteBCUnited @MichaelLeeBC @KevinFalcon Right on @jaimestein! Good to see intelligent people with solid character entering politics. Gives me hope (and makes me want to move to BC if only so I can vote for you!)

@taraarobertson The worst! As a reluctant public transit aficionado, this is one of my biggest pet peeves.

The first rule of machine learning:

Do not start with machine learning.

Unfortunately, to a hammer, everything looks like a nail.

Whenever I get a call from a company to help them, they have already made their mind up: they want to use machine learning. It's always tempting to start the conversation there. Yet, machine learning is usually not the best way to solve most problems.

Here is a better approach:

Step 1 - Start with simple heuristics

Heuristics is a fancy word. I prefer to call them "simple rules."

You should start most problems by writing simple rules. It may not be perfect, but it's a better solution than jumping straight into machine learning.

There are two significant advantages to this approach. First, you'll learn much more about the problem you need to solve. Second, you'll have a baseline to compare against any future machine-learning solution.

For example, imagine you are building an online store and you want to show your users a list of recommended products.

Instead of thinking about machine learning, start with a fixed list of recommendations. You can upgrade that to a list sorted by popularity. You can solve this problem in many ways before thinking of building a model.

Step 2 - Replace heuristics with a simple model

There's a point where you don't want to keep adding complexity to your rules. Maintaining a simple machine-learning model is easier than a codebase of complex rules.

When your rules get out of hand, train a simple model and replace your heuristics with it.

People usually recommend starting with simple algorithms like linear regression or decision trees. This makes sense, but simplicity doesn't always refer to the algorithm but how easy it is to use.

For example, a ResNet-50 model is a complex convolutional neural network. But you can download a pre-trained version and start using it fast.

Step 3 - Increase complexity

There's a point where your simple model can't give you better performance.

Here is when you should start exploring more complex solutions. Sometimes, a better model can improve your results. Sometimes, you need to combine a few models together.

If I've learn one thing over the years, is that simplicity always wins.

@ChiefPeggTFS @Toronto_Fire @TPFFA It was a beautiful service. Rest in peace Sean.

@franchisewolf Catchy name. I approve.

@nigeldacosta @Dyson Unspeakable horrors beyond your human comprehension.

[Casey Rovinelli @caseyrovinelli]

Honest question. Why hasn't @Dyson created a bathroom fan yet? Seems like a logical addition to their product lineup, right?

[Casey Rovinelli @caseyrovinelli]

@etherington Super cool. Great to have you on the team.

@nic_detommaso @OMERSVentures Thanks for the shout out. Happy to chat with anyone thinking of changing firms. (Also open to folks in NYC or Toronto)

@anothercohen Try the US equivalent of this: https://t.co/jFdgFYDx2N

No drugs. Basically just sterile saline water. Snort as much into your sinuses as you can, one nostril at a time. Wait. Blow your nose. Repeat periodically. The best way to decongest + avoid a sinus infection developing.
