US moves to tackle scourge of ‘robocalls’

Posted by in category: robotics/AI

“Hello? Who’s calling?” For many Americans these days, the call is coming from a “bot” or automated program that seeks to trick them into giving up money or important personal data.

The scourge of “robocalls” by the billions has prompted US regulators to adopt new rules allowing carriers to implement tools to block calls with suspicious origins.

The automated calls may tell respondents that they owe back taxes or other bills that need to be settled immediately, or direct them to call numbers where they are charged for the connection.

Software Is Called Capable of Copying Any Human Voice

Posted by in categories: biotech/medical, robotics/AI

Who are you really talking to?

AT&T Labs will begin selling speech software it says is so good at reproducing sounds, inflections and intonations of human voice, that it can recreate voices and even bring those of long-dead celebrities back to life; Natural Voices software, which turns printed text into synthesized speech, makes it possible for company to use recording of person’s voice to utter things person never actually said; utterances still contain few robotic tones and unnatural inflections, leading competitors to question whether it is substantial step up from existing products; tests suggest it may be first text-to-speech software to raise specter of voice cloning, replicating person’s voice so perfectly that human ear cannot tell difference; photo (M)

Can Self-Replicating Robots Lead To A Society Without Scarcity?

Posted by in categories: 3D printing, economics, governance, robotics/AI

The status quo of economies today seems to be leaning towards automation as the base provider of all products and services. Owing to rise of robots in factories and AI in computing, automation is becoming one of the most integral parts of society.

While self-replicating robots have largely been kept to science fiction books, their rise is becoming more and more likely with the rise of supplementary technologies such as 3D printing.

This technology could hold the key to a truly post-scarcity society. The question then arises, how would the rise of a post-scarcity society affect human institutions such as economy and governance that rely on scarcity?

AI software reveals the inner workings of short-term memory

Posted by in categories: biological, neuroscience, robotics/AI

Research by neuroscientists at the University of Chicago shows how short-term, working memory uses networks of neurons differently depending on the complexity of the task at hand.

The researchers used modern artificial intelligence (AI) techniques to train computational neural networks to solve a range of complex behavioral tasks that required storing information in short term . The AI networks were based on the biological structure of the brain and revealed two distinct processes involved in short-term memory. One, a “silent” process where the brain stores short-term memories without ongoing neural activity, and a second, more active process where circuits of fire continuously.

The study, led by Nicholas Masse, Ph.D., a senior scientist at UChicago, and senior author David Freedman, Ph.D., professor of neurobiology, was published this week in Nature Neuroscience.

You Don’t Need That Bulky CRT Oscilloscope Anymore

Posted by in category: robotics/AI

While it might be nice to use a $4,000 oscilloscope in a lab at a university or well-funded corporate environment, a good portion of us won’t have access to that kind of equipment in our own home shops. There are a few ways of getting a working oscilloscope without breaking the bank, though. One option is to find old CRT-based unit for maybe $50 on craigslist which might still have 60% of its original 1970s-era equipment still operational. A more reliable, and similarly-priced, way of getting an oscilloscope is to just convert a device you already have.

The EspoTek Labrador is an open-source way of converting a Raspberry Pi, Android device, or even a regular run-of-the-mill computer into a working oscilloscope. It’s a small USB device with about a two square inch PCB footprint that includes some other features as well like a signal generator and logic analyzer. It’s based on an ATxmega which is your standard Arduino-style AVR microcontroller but geared for low power usage. It looks as though it is pretty simple to use as well, and the only requirements are that you can install the software needed for the device on whatever computing platform you decide to use.

While the Labrador is available for sale at their website, it is definitely a bonus when companies offer products like this but also release the hardware and software as open source. That’s certainly a good way to get our attention, at least. You can build your own if you’d like, but if you’d rather save the time you have pre-built options. And it doesn’t hurt that most of the reviews of this product seem to be very favorable (although we haven’t tried one out ourselves). If you’d prefer an option without a company backing it, though, we have you covered there too.

One Step Closer to Deep Learning on Neuromorphic Hardware

Posted by in categories: biological, robotics/AI, transportation

A group of researchers at Sandia National Laboratories have developed a tool that can cross-train standard convolutional neural networks (CNN) to a spiking neural model that can be used on neuromorphic processors. The researchers claim that the conversion will enable deep learning applications to take advantage of the much better energy efficiency of neuromorphic hardware, which are designed to mimic the way the biological neurons work.

The tool, known as Whetstone, works by adjusting artificial neuron behavior during the training phase to only activate when it reaches an appropriate threshold. As a result, neuron activation become a binary choice – either it spikes or it doesn’t. By doing so, Whetstone converts an artificial neural network into a spiking neural network. The tool does this by using an incremental “sharpening process” (hence Whetstone) through each network layer until the activation becomes discrete.

According to Whetstone researcher Brad Aimone, this discrete activation greatly minimizes communication costs between the layers, and thus energy consumption, but with only minimal loss of accuracy. “We continue to be impressed that without dramatically changing what the networks look like, we can get very close to a standard neural net [in accuracy],” he says. “We’re usually within a percent or so on performance.”
