I doubt the guru's use algorithms. It's a word that sounds fancy and intimidates people. It's just another mechanism guru's use via fancy verbiage to awe you in order to separate you from your money.
If you're looking for what's hot you can find that out by thinking about how the markets work. Quantify your market first. Are you looking for multi-family? If so then bus lines, malls and a high population of job creators that don't have time to do all the little things is important. There are dozens of other factors in your criteria but you get the point for multi-family.
If you're doing single family look for areas that have good school districts, large populations, high list-to-sales price ratio, low days on market, path of progress, etc...You don't need algorithms. You just need to think about what would be important to you as a potential home owner and what will happen to your money when you buy a house. If you'd hesitate to buy in an area as a resident then you probably should as an investor too. Save your money by not buying their programs and talk with some local realtors (good ones) or local investors. It's not what you think but how you think that will create your mint.
