Australia's Defence Trade Controls Act was recently updated and now prohibits the "intangible supply" of encryption technologies, and hence subjects many ordinary teaching and research activities to unclear, potentially severe, export controls.
I'll have to think about it more, but I think this relates to the difference between logical implication and probabilistic inference. "A => B, B, therefore A" is false. But if P(B | A) is high then learning B is true will generally increase your estimate that A is true.
Two weeks ago we blogged about a visualization tool designed to help us understand how neural networks work and what each layer has learned (http://goo.gl/pUfbyH). In addition to gaining some insight on how these networks carry out classification tasks, we found that this process also generated some beautiful art.
Now you can make your own images using an open source IPython notebook, which allows you to choose which layers in the network to enhance, how many iterations to apply and how far to zoom in. Alternatively, different pre-trained networks can be plugged in.
It'll be interesting to see what imagery people are able to generate. If you post images to Google+, Facebook, or Twitter, be sure to tag them with #deepdream so other researchers can check them out too.
This is an important issue that has gotten little mainstream media coverage, and while the article is long, I think it's worth reading. The worst case here is very, very bad: common encryption systems are broken by hackers who now have free access to emails, bank accounts, etc., AND foreign governments worldwide (especially repressive ones) similarly gain access to everyone's communications.
In fact it's difficult to overstate the severity of the downsides of the FBI's call for backdoors, and the article slowly makes clear just how isolated and out of touch the opinion that these sorts of access points are a good idea is in the larger community of experts.
What is amazing is how well some people do, despite the challenges. Most people with this disease struggle to get through school. My sister Anna is a registered nurse.
Media release: New day sets to raise brain awareness
You may have not heard of the corpus callosum, which is exactly why 2 July is being celebrated as the first National Corpus Callosum Awareness Day.
A University of Queensland researcher working with colleagues at The Murdoch Children’s Research Institute is at the forefront of efforts to understand the brain’s most remarkable feature, which acts as a bridge between the left and right hemispheres of the brain.
Queensland Brain Institute scientist Professor Linda Richards has dedicated her career to studying how the corpus callosum is wired, and what happens when the process goes wrong.
“National Corpus Callosum Awareness Day is about appreciating how extraordinary this part of the brain really is,” Professor Richards said.
“In a small area around two hundred million nerves intersect, and in most cases wire correctly, which if you step back and think about, is quite amazing,” she said.
“Unfortunately the process does go wrong, and around one in 3000 people is born with a corpus callosum malformation, which can impact language skills, vision and hearing, as well as physical coordination.”
The awareness day is the brainchild of Australian Disorders of the Corpus Callosum (AusDoCC), a volunteer organisation that offers support and information to families or individuals with a disorder of the corpus callosum.
AusDoCC Secretary Maree Maxfield said the disorder can be very debilitating, affecting both the people with the condition and their families.
“Due to improved imaging techniques, a disorder of the corpus callosum may now be discovered in utero, so the condition is being diagnosed much earlier,” Ms Maxfield said.
“Being rare, there has previously been very little awareness or information and it can be a shock for a new parent to be told their baby will be missing a large brain structure,” she said.
“Families now have support as they begin what was once a lonely journey.”
The group sees 2 July as becoming an annual day of awareness and recognition for sufferers of corpus callosum conditions.
“Symbolically, like the corpus callosum’s position in the brain, July 2 is the middle day of the year,” Ms Maxfield said.
