One chip to rule them all: It natively runs all types of AI software

Posted by in categories: information science, robotics/AI

We tend to think of AI as a monolithic entity, but it has actually developed along multiple branches. One of the main branches involves performing traditional calculations but feeding the results into another layer that takes input from multiple calculations and weighs them before performing its calculations and forwarding those on. Another branch involves mimicking the behavior of traditional neurons: many small units communicating in bursts of activity called spikes, and keeping track of the history of past activity.

Each of these, in turn, has different branches based on the structure of its layers and communications networks, types of calculations performed, and so on. Rather than being able to act in a manner we would recognize as intelligent, many of these are very good at specialized problems, like pattern recognition or playing poker. And processors that are meant to accelerate the performance of the software can typically only improve a subset of them.

Scientists find huge world of hidden galaxies, changing our understanding of the universe

Posted by in category: space

This is the first multiple discovery of its kind, and such an abundance of this type of galaxy defies current models of the universe.


Previously unknown webs of stars are more spectacular than our own, say researchers.

Big Bang theory wrong? Star older than Universe discovered — threat of ‘scientific crisis’

Posted by in category: cosmology

The Universe is thought to have popped into existence some 13.8 billion years ago when an infinitesimal point expanded billions of lightyears across in just a fraction of a second. The Big Bang theory has stood for the best part of 100 years after Belgian physicist Georges Lemaître first proposed in 1927 the expansion of the Universe could be traced back to a single point. However, the well-accepted model is now under the microscope after a team of researchers found a star which appears to be older than the cosmos.

Spending Bitcoin in person is easy (What happens in background is elegant)

Posted by in categories: bitcoin, cryptocurrencies, economics

Today, I was co-host of an online cryptocurrency symposium—taking questions from hundreds of visitors. A common question goes something like this:

Can Bitcoin be used in person—or
is it just for internet commerce?

Our panel had a moderator, and also an off-screen video director. As I cleared my throat in preparation to offer a response, a voice in my ear reminded me that it was not my turn. The director explained that another panelist would reply. It was a highly regarded analyst and educator in Australia. Realizing that that she was calling the shots, I deferred.

I was shocked as I listened to a far off colleague suggest that Bitcoin is not useful for in-person payments. I wonder how he explains this to the grocers, tailors, lawyers, theme parks and thousands of retailers who save millions of dollars each year by accepting bitcoin—all without risk of volatility and even if they demand to instantly convert sales revenue into Fiat currency.*

Position Statement 56: Mental Health Treatment in Correctional Facilities

Posted by in categories: biotech/medical, health, law enforcement, neuroscience

“Over the past 50 years [America has] gone from institutionalizing people with mental illnesses, often in subhuman conditions, [in state mental health hospitals] to incarcerating them at unprecedented and appalling rates—putting recovery out of reach for millions of Americans […] On any given day, between 300,000 and 400,000 people with mental illnesses are incarcerated in jails and prisons across the United States, and more than 500,000 people with mental illnesses are under correctional control in the community.” [1] Mental Health America (MHA) supports effective, accessible mental health treatment for all people who need it who are confined in adult or juvenile correctional facilities or under correctional control. People with mental health and substance use conditions also need an effective classification system to protect vulnerable prisoners and preserve their human rights. [2] Notwithstanding their loss of their liberty, prisoners with mental health and substance use conditions retain all other rights, and these must be zealously defended.

Background

In the past decade, America has been locking up increasing numbers of individuals with mental health conditions. [3] MHA is both concerned by and opposed to the increasing use of criminal sanctions and incarceration, replacing the state mental hospitals with much more drastic curtailment of personal liberty and preclusion of community integration and community-based treatment. [4] Prisoners with mental health conditions are especially vulnerable to the difficult and sometimes deplorable conditions that prevail in jails, prisons, and other correctional facilities. Overcrowding often contributes to inadequacy of mental health services and to ineffective classification and separation of prisoner classes. It can both increase vulnerability and exacerbate mental illnesses. For these and other reasons, MHA supports maximum reasonable diversion. [5].
