Today I saw something with more hype than I would expect from a respected tech company. “eBay determines this price through a machine learned model of the product’s sales prices within the last 90 days.”
In my opinion this price prediction is not machine learning. It’s just math. It’s not a machine learned anything. It fails 1-5 of Stephen’s tests.
As Machine Learning captures our imagination, it’s important to separate the material from the hype. Here are 5 simple questions you should ask to help reduce AI hype:
“How much training data is required?”
“Can this work unsupervised (= without labelling the examples)?”
“Can the system predict out of vocabulary names?” (i.e. Imagine if I said “My friend Rudinyard was mean to me” – many AI systems would never be able to answer “Who was mean to me?” as Rudinyard is out of its vocabulary)
“How much does the accuracy fall as the input story gets longer?”
“How stable is the model’s performance over time?”

Snow caves are fun to build and provide warm places to sleep and take shelter from a storm. This is a brief how-to guide to building a snow cave.
The snow cave in this example was built by 4 people near Skinner Hut at the edge of the timberline in late-December 2015 at 11,620 feet. Builders were Brett Poulin, Chris, Nick, and me, Neal Mueller. The cave we built was large enough to sleep and provide eating quarters and shelter for 4 people. It included a vapor escape for cooking.

Video of 1997 keynote 2-months after Jobs returned to Apple. Sets the vision as something other than speeds and feeds. Launches the brand for the next 15-years, which you can see even today. The 1997 ‘Think Different’ billboards are reminiscent of the 2015 ‘Shot on Iphone 6’ billboards.
