At my work we use it to do large-scale analysis of remote sensing data, in particular segmentation of satellite imagery to provide land monitoring services.

#52Forecast loan payment defaults for 90 days or longer, 3 months in advance using a tree based model.
What's your training set?
Re: Ask HN: What do you use Machine Learning for?
#53I use it as something to worry about not knowing how to use, and how that might make me unemployable in a few years, while also having no obvious need for it at all, and therefore no easy avenue towards learning it, especially since it requires math skills which have completely rusted over because I also never need those, so I'd have to start like 2 levels down the ladder to work my way back up to it. I've found it v…
As a guy who's going into ML, I'm worried about AI and products like DataRobot clobbering the market for data scientists. DataRobot gets glowing reviews for automating the setup of dozens of ML models, replacing weeks of effort by teams of ML specialists. It's very expensive though.

#54I'm not using it at this moment, but in a couple of weeks I'll have a newborn, and I was thinking of taking pictures of him every time he is upset, and then tagging the photo with what ends up being the resolution (feed, change, or nap) and seeing if I could build a classifier that could figure out what he needs just from a picture of his angry face. Semi-related, but if anyone is using the AWS tools for their AI, pl…
Hey I'm having a newborn as well and wouldn't mind contributing to the sample set if you make a web form or API for me to post to.

I'm a person (software engineer) who knows some ML and I tell this to my coworkers when they express similar sentiments: If you're worried about ML taking your job then you're not thinking straight. If the world has automated to the degree where programmers are non longer needed in 3 or 10 years then you will definitely have other things to worry about. Truckers, farmers, taxis, cops, and construction crews will likely all be automated before programmers are, and when that happens it will cause a huge global crisis and leave millions unemployed. Programmers will be sometime later when we figure out general AI.
Alternative scenario: loss of jobs to automation and inadequate social safety net cause social unrest and communist revolution. We've seen this kind of thing before.
In short: if you're looking at Hacker News then doing ML is likely irrelevant.

#56Earlier quoted context omitted.
How do you get the data for training how a break-in looks like?
Couldn't you just train it on genuine visitors and then use the probability of it being a genuine visitor to determine whether it is a break in?
I imagine only training on genuine visitors would be tricky with any traditional classification approach. Even having a 90/10% split of positive/negative training data is difficult since a lot of classifiers will just degrade to a majority vote.
Maybe a Restricted Boltzmann Machine or something similar?

Like encryption, the math is necessary when you build it, not when you use it. You can go quite far by just treating it as a black box.
Well, yes, until you are stumbled upon something that is not really working as you may expect and then you need to find out why... ML, without understanding the math can be a very strange place to roam around. I will suggest wrapping your head around basic math at least. The first chapter of the deep learning book is very nice in fact if you want to do this. http://www.deeplearningbook.org/

#58I work for a large multi-hospital corporation.
We use machine learning to predict the risk of a patient, after an inpatient admission, being readmitted in 30 days post discharge. If the risk is high, we proactively put process in place to reduce the readmission risk.Re: Ask HN: What do you use Machine Learning for?
#59Building a smart home security system, so you can be notified when your friends have arrived, or if someone is trying to break into your home. Machine learning is very useful here, as you can train the system to recognise what your friends look like, or what a break-in might look like.
How do you get the data for training how a break-in looks like?
I'm guessing this would also use data for time of day, and if anyone is at home

It's more like concern that not having those skills (or something comparably advanced, but also with no immediate use in my work or life) will force me to slide down, rather than up, if/when competition from overseas finally hollows out the middle of the US developer market—though I'm not sure why this hasn't already happened, so maybe I'm wrong to worry about that at all. Not concern that ML programs will start writing other programs well enough to be a direct threat.
