System learns to distinguish words’ phonetic components, without human annotation of training data

Posted by in category: robotics/AI

Every language has its own collection of phonemes, or the basic phonetic units from which spoken words are composed. Depending on how you count, English has somewhere between 35 and 45. Knowing a language’s phonemes can make it much easier for automated systems to learn to interpret speech.

In the 2015 volume of Transactions of the Association for Computational Linguistics, MIT researchers describe a new machine-learning system that, like several systems before it, can learn to distinguish . But unlike its predecessors, it can also learn to distinguish lower-level phonetic units, such as syllables and phonemes.

As such, it could aid in the development of speech-processing systems for languages that are not widely spoken and don’t have the benefit of decades of linguistic research on their phonetic systems. It could also help make speech-processing systems more portable, since information about lower-level phonetic units could help iron out distinctions between different speakers’ pronunciations.

First ever “photo” of light as particle and a wave

Posted by in categories: particle physics, quantum physics

One of the most confounding implications of quantum physics is that light can behave as both a particle (photon) and a wave, depending on the nature of the observation. This is called wave-particle duality, and it has been extremely difficult to picture, let alone observe in both stages simultaneously. Now, physicists publishing in Nature Communications report that they have been able to capture a photograph of wave/particle duality ‘in action’, so to speak. This TED video explains the nature of the effect:

You’re not irrational, you’re just quantum probabilistic: Researchers explain human decision-making with physics theory

Posted by in categories: neuroscience, quantum physics

The next time someone accuses you of making an irrational decision, just explain that you’re obeying the laws of quantum physics.

A new trend taking shape in not only uses to explain humans’ (sometimes) paradoxical thinking, but may also help researchers resolve certain contradictions among the results of previous psychological studies.

According to Zheng Joyce Wang and others who try to model our decision-making processes mathematically, the equations and axioms that most closely match human behavior may be ones that are rooted in quantum physics.

Scientists Hope To Resurrect A Dead Girl Who Wanted To Live Inside A Computer

Posted by in categories: computing, life extension, neuroscience

Kim Suozzi died at age 23 from glioblastoma — a deadly brain tumour.

When she died in 2013, she made sure her fight for survival, albeit an unusual one, would not be forgotten.

She wanted to live forever through a computer and chose to have her brain frozen in the hopes that it may one day be resurrected and transformed into digital code.

Extending Galactic Habitable Zone Modeling to Include the Emergence of Intelligent Life — By Morrison Ian S. and Gowanlock Michael G. | Astrobiology

Previous studies of the galactic habitable zone have been concerned with identifying those regions of the Galaxy that may favor the emergence of complex life. A planet is deemed habitable if it meets a set of assumed criteria for supporting the emergence of such complex life. In this work, we extend the assessment of habitability to consider the potential for life to further evolve to the point of intelligence—termed the propensity for the emergence of intelligent life, φI.

Physicists develop key component for terahertz wireless

Posted by in categories: electronics, internet, mobile phones, physics

Terahertz radiation could one day provide the backbone for wireless systems that can deliver data up to one hundred times faster than today’s cellular or Wi-Fi networks. But there remain many technical challenges to be solved before terahertz wireless is ready for prime time.

Researchers from Brown University have taken a major step toward addressing one of those challenges. They’ve developed what they believe to be the first system for multiplexing terahertz waves. Multiplexers are devices that enable separate streams of data to travel through a single medium. It’s the technology that makes it possible for a single cable to carry multiple TV channels or for a fiber optic line to carry thousands of phone calls at the same time.

Future Transhumanist Tech May Soon Change The Definition Of Disability

Posted by in categories: cyborgs, transhumanism, transportation

My first article for TechCrunch. The story is on disability & transhumanism:


Radical technologies around the world may soon overhaul the field of disability and immobility, which affects in some way more than a billion people around the world.

MIT bionics designer Hugh Herr, who lost both his legs in a mountain climbing accident, recently said in a TED Talk on disability, “A person can never be broken. Our built environment, our technologies, are broken and disabled. We the people need not accept our limitation, but can transcend disability through technological innovation.”

Paralyzed Man Successfully Given Prosthetic Hand That Can ‘Feel’

Posted by in categories: biotech/medical, cyborgs, electronics, neuroscience

A 28 year old man who has been paralysed has been given a new sense of touch following a new breakthrough that saw electrodes places directly into the man’s brain.

The research and clinical trial has been carried out by DARPA, the US Military’s research agency. Essentially, the man (who has not been named) is now able to control his new hand and feel people touching it because of two sets of electrodes: one array on the motor cortex, the part of the brain which directs body movement, and one on the sensory cortex, which is the part of the brain which feels touch.
