What is Machine Learning?

Inference and learning with massive datasets using intelligent machines.

-UBC CSPC340 (Machine Learning & Data Mining)

A branch of artificial intelligence that relies heavily on probability statistics uses data to make predictions and learn.

The Restaurant Case

John

Jack used to come a lot, why he hasn't showed up for a while?

Why Bill's bar is more popular?

Is Roy a slow server?

Vancouver's best selling beer

Average cost to run a restaurant

Query From Computer

Busiest hour of the week

Data Driven Decision

John

People like the happy hour in Bill's Bar so much that the keep going there even when it's not happy hour.

 

Roy is a great server, he sells more food, and that's why it seems like he is slow.

 

The Honey BBQ Rib is the best seller, and it has 10% chance of sold out during weekend. So get enough stock before weekend.

But,is that good enough?

But, Is that Good Enough?

Hey John, let's talk.

Factor 1, 34, 42443, 254432 & 4342343214 are the most significant factors. Align your strategies in those factors with the best restaurants. You can beat Bill's Bar in a week.
