Web Search: Crash Course AI #17



Today we’re going to talk about search engines, which are just AI systems that try to help us find what we’re looking for. Search engines can be the sort that serve up a list of results, like during a Google or Bing search, using web crawlers, an inverted index, and measuring stuff like click through and bounce back to figure out what you want to see. They can also be the kind that give you answers, like when you ask Siri or Alexa a question, relying on knowledge bases. Admittedly, these systems aren’t perfect so next week we’ll talk about bias in AI systems like this.

I'm bouncing through my YouTube subscriptions, and the one I watched right before this one was Computerphile's video on language parsing. Good one to watch alongside this one, if you're into Computerphile.

Oh boy, bias… here's comes the episode I've been dreading. I usually really like Crash Course but sometimes you folks go too far on the "woke"mentality. According to the United States Bureau of Labor, about 90% of nurses are female. If this holds up globally, then showing 90% images of female nurses would not be biased – it would be an accurate reflection of reality. 85% or 95% female nurses would be biased. A more even gender distribution may be desirable, but that's not the point; if I say "show me pictures of nurses," I either want to know what… Read more »

The scriptwriters have done a great job explaining AI in this series and don't get this negatively, because it is a lot better than I could ever do, but it feels so extremely oversimplified that it makes me angry. :'D

If search engines can help us find what we're looking for, can it finally help me find those droids?

I'm sorry but NO, search engines haven't been getting better and better at helping us find what we are looking for. Back when google used and actually obeyed boolean search operators, it used to be an extremely powerful research tool. Now it's basically useless unless you are looking for advertisements or really basic information. For any kind of esoteric or very specific information that doesn't fit under google/scholar, google has become completely useless. It's good at showing you what it wants you to be searching for or what it thinks you are searching for, but not what you are actually… Read more »

0:21 – Sandwiches don't have connected buns? So Subway's submarine sandwiches are really hotdogs? 🤨

Submarine sandwiches often have a connected bread, and they're sandwiches. I also don't think hot dogs are sandwiches, but I don't quite know why… Maybe it's the way you hold it? Like, even with a connected-bread sub, you hold it so the bread is horizontal with a top and bottom, but with a hot dog, you hold it with the connection at the bottom, open at the top, and bun on the sides. Maybe that's the distinction?

Also… I wonder what percentage of CrashCourse's demographic are old enough to recognize and remember that dial-up sound? 😂
