Slightly contrarian, or maybe not-but is anyone else sort of fatigued with social media trying it's hardest to do it all for you? Algorithmic timelines telling me what happened while I was gone (trust me, twitter...I would have gotten to it eventually), prioritizing what shows up (trust me facebook, I do a very good job hiding content on my own), telling me what I ought to buy (trust me, Amazon if I wanted it-I'd eit…

Know those little emails that Facebook sends you throughout the day? I've turned most of mine off, but I still like to know when people mention me, or get a page update. Well, I figured out today that when Facebook has these, it doesn't necessarily send them to you right away. Instead it waits until it looks like you've bailed off the site to do something else. Then you get an email notification -- drawing you back i…

I don't use facebook, but couldn't that also be an optimization? Like don't send the user email notifications if they're already on the site where they can see the # of notifications?

From a revenue perspective, the behavior that the GP is describing IS an optimization.

I think FB has a strategy here that plays along well with their messenger (and their emphasis on bots). Imagine the example they give "I would like to sell my old bike for $200, anyone interested?", being matched with another user who said "I am looking for a cheap bike nearby". This plays right into google's territory, with the ability to organize and match people's intentions.

Yesterday I mentioned vodka to my wife in Facebook Messenger and a few minutes later she saw a vodka advertisement on her timeline. Obviously Messenger will never include end to end encryption.

are you serious? They had to decrypt text so that your wife can read it and that is where they started displaying vodka ads. edit - I meant to say even if they had end-to-end encryption then your text would still need to be decrypted so that other user can read it.

End-to-end encryption means the server doesn't know the content of the message. Only the clients, the end-points, have the decryption key.

Heh yeah I wrote about this a while back - http://techcrunch.com/2013/01/27/facebooks-categorial-impera... But you add human intelligence to this kind of thing and it starts getting creepily accurate much of the time if you're looking to promote certain behaviors, expose others, or what have you.

On yesterday's episode of POI a character said that the Machine (an AI) has to contain a simulation of a person in order to understand what that person will do.

I think AlphaGo had a pretty good simulation of its human opponent, even though strategy and intuition are hard.

Ya know, I normally don't believe in these "Facebook is listening into your conversations"-type voices and opinions because it seems like such an invasion of privacy and the company wouldn't do something like _that_ without permission. However, after a recent episode where I _know_ Facebook was listening to my conversation[1], I'm now much more nervous based on this machine learning news. I've become highly critical and pessimistic when Facebook says things like "Better understanding people's interests" and "New deep neural network architectures", not so much because of what their intent with the data is, but how they receive that data. It's done so sneakily, this is what I disagree with. I normally don't have a problem with Google reading my emails and suggesting news topics on Google Now + my flights, etc., because they ask if they can, but with Facebook, there's an era of creepiness that they are always listening.

[1]: This past weekend, a close friend was telling me about his friend who works at Google and the following morning, this Google person came up on my "Friends suggestions". It was the most bizarre thing... I also confirmed with my friend if he looked this Google guy up later on Facebook, which may have prompted his Google friend to show up on mine, and he said he didn't touch Facebook after our conversation.

EDIT: For further clarity.

I would be interested to learn more about their research behind it. Will there be any papers released? Specifically: how much data did they train on? How many machines for how long? How did the different NN architectures perform? I guess those things would be fine to share without revealing the inner workings.

Such results as they published today have become pretty standard in the academic papers. I was wondering why weren't there any cutting edge applications of deep learning in text, as a product. It's probably too expensive to run the necessary hardware to use the latest and greatest ideas.

AlphaGo didn't simulate its opponent, it used the entire recorded history of Go games to extrapolate what is the best move to play in a particular situation (falling back to Monte-Carlo simulations of possible games after reducing the problem).

Why did you think Facebook wouldn't do that? In their view, any content you provide to their site becomes their property. Why wouldn't that include conversations. Considering the fact that everything is unencrypted once it reaches Facebook, it's a mistake to assume good faith on the part of a company that makes its living trying to make you spend more of your life on their website.
