Visualizing Representations: Deep Learning and Human Beings

How should we think about neural networks? How can they help us think, ourselves?

Highlights:

* An exploration of very general techniques for visualizing neural networks.
* Visualizations of sophisticated models from Google's deep learning research group.
* meta-SNE, a new algorithm for visualizing entire spaces of neural networks, instead of individual ones.
* A visualization of English Wikipedia, as a whole!
* A way to use deep learning for gender studies (and more)!

So far BitSquare is is the most convincing P2P decentralised exchange project I've found. It's got a lot more credibility with me than many of the other attempts at this (mastercoin, counterparty, etc) because it works how I expected a P2P exchange to work. In other words, it's being done how I would do it, if I were building a P2P exchange instead of a crowdfunding app:

* It's a desktop app that talks directly to the Bitcoin P2P network, using bitcoinj in a similar manner to Lighthouse (i.e. it's a specialised Bitcoin wallet).
* It's using a mature P2P DHT for storing the order book (tomp2p).
* It has a reasonably professional looking GUI.
* The author has put a lot of thought into abuse and dispute mediation.
* They have a plan for using 2-of-3 multisig transactions.

In effect BitSquare is a fully P2P version of localbitcoins. 

Additionally, they are talking to waxwing and the other researchers working on TLS Notary, which will be a highly useful component of dispute resolution in any P2P exchange mechanism in future.

Check out the video and see what you think. It's early days yet, but this is the kind of app I hoped people would build on top of bitcoinj.

Can tiny electronics help unlock the mystery of tear glucose, in the hopes of someday finding an easier way for people with diabetes to manage their disease?
