Quoc Le | Innovators Under 35 | MIT Technology Review

Quoc Le | Innovators Under 35 | MIT Technology Review | Science, Technology, and Current Futurism | Scoop.it

While at Stanford, Le worked out a strategy that would let software learn things itself. Academics had begun to report promising but very slow results with a method known as deep learning, which uses networks of simulated neurons. Le saw how to speed it up significantly—by building simulated neural networks 100 times larger that could process thousands of times more data. It was an approach practical enough to attract the attention of Google, which hired him to test it under the guidance of the AI researcher Andrew Ng (see “A Chinese Internet Giant Starts to Dream”).

 
Sharrock's insight:

It amazes me that the idea of machine "deep learning" became public in 2012 (written 8/19/14). That's only 2 years ago! With the invention of the synapse processor chip and chips similar to this, deep learning will probably increase in terms of power, granularity, and impact on even more human-superior tasks: "The technique is now used in Google’s image search and speech-recognition software. The ultra-intelligent machine Le once imagined remains distant. But seeing his ideas make software smart enough to assist people in their everyday lives feels pretty good." Such technology will have more immediate impacts on radiology and diagnostics, as it does in the image search services, but may also increase capabilities in music and reading recommendation services. Who knows what else?

New technique creates highly accurate detailed 3D maps in real time

New technique creates highly accurate detailed 3D maps in real time | Science, Technology, and Current Futurism | Scoop.it

Computer scientists at MIT and the National University of Ireland (NUI) at Maynooth have developed a mapping algorithm that creates dense, highly detailed 3-D maps of indoor and outdoor environments in real time.

 

The researchers tested their algorithm on videos taken with a low-cost Kinect camera, including one that explores the serpentine halls and stairways of MIT’s Stata Center. Applying their mapping technique to these videos, the researchers created rich, three-dimensional maps as the camera explored its surroundings.

 

As the camera circled back to its starting point, the researchers found that after returning to a location recognized as familiar, the algorithm was able to quickly stitch images together to effectively “close the loop,” creating a continuous, realistic 3-D map in real time.

 

The technique solves a major problem in the robotic mapping community that’s known as either “loop closure” or “drift”: As a camera pans across a room or travels down a corridor, it invariably introduces slight errors in the estimated path taken. A doorway may shift a bit to the right, or a wall may appear slightly taller than it is. Over relatively long distances, these errors can compound, resulting in a disjointed map, with walls and stairways that don’t exactly line up.

 

In contrast, the new mapping technique determines how to connect a map by tracking a camera’s pose, or position in space, throughout its route. When a camera returns to a place where it’s already been, the algorithm determines which points within the 3-D map to adjust, based on the camera’s previous poses.

 

“Before the map has been corrected, it’s sort of all tangled up in itself,” says Thomas Whelan, a PhD student at NUI. “We use knowledge of where the camera’s been to untangle it. The technique we developed allows you to shift the map, so it warps and bends into place.”

 

The technique, he says, may be used to guide robots through potentially hazardous or unknown environments. Whelan’s colleague John Leonard, a professor of mechanical engineering at MIT, also envisions a more benign application.

Online collaboration: Scientists and the social network | Science, Technology, and Current Futurism | Scoop.it

In 2011, Emmanuel Nnaemeka Nnadi needed help to sequence some drug-resistant fungal pathogens. A PhD student studying microbiology in Nigeria, he did not have the expertise and equipment he needed. So he turned to ResearchGate, a free social-networking site for academics, and fired off a few e-mails. When he got a reply from Italian geneticist Orazio Romeo, an inter­national collaboration was born. Over the past three years, the two scientists have worked together on fungal infections in Africa, with Nnadi, now at Plateau State University in Bokkos, shipping his samples to Romeo at the University of Messina for analysis. “It has been a fruitful relationship,” says Nnadi — and they have never even met.

Notetaking vs notemaking

Notetaking vs notemaking | Science, Technology, and Current Futurism | Scoop.it

From my review of the notetaking literature (a focus of my dissertation), I found two schools of thought. One was note taking as a record of events. This would correspond to the minutes of a meeting or a transcript of a video. With this concept, teachers would give students a copy of important facts as a handout or file (or make the students copy them from the board or screen). Every student would have the same information in a standard style. [I've interviewed students who listed copying notes as their least favorite class activity.]

 

The other thought is notetaking as a form of information processing (notemaking might be a better term). As students read text, listen to a lecture, participate in a discussion, or watch a video, they connect what they’re seeing or hearing to what they already know, ask questions, reflect on their understanding, and summarize. This could be in a variety of formats depending on the information: Cornell notes, sketches, lists, annotating text, graphic organizers. Much of the literature on science notebooks reflects this concept of note taking.*

A novel manufacturing method could make it practical to stack solar cells and convert more of the energy in sunlight into electricity.
Sharrock's insight:

excerpt: "Semprius has come up with three key innovations: a cheap, fast way to stack cells, a proprietary way to electrically connect cells, and a new kind of glue for holding the cells together. In its designs, Semprius uses tiny individual solar cells, each just a millimeter across. That reduces costs for cooling and also helps improve efficiency."

Astrocytes, The Brain's Lesser Known Cells, Get Some Cognitive Respect

"What I thought quite unique was the idea that astrocytes, traditionally considered only guardians and supporters of neurons and other cells, are also involved in the processing of information and in other cognitive behavior," says Verma, a professor in the Laboratory of Genetics and American Cancer Society Professor.

Sharrock's insight:

excerpt: "It's not that astrocytes are quick—they're still slower than neurons. But the new evidence suggests that astrocytes are actively supplying the right environment for gamma waves to occur, which in turn makes the brain more likely to learn and change the strength of its neuronal connections."

Les transhumanistes sont bien obligés de reconnaître les dangers d'un "totalitarisme cybernétique" que brandit Jaron Lanier.

luiy's curator insight, July 10, 5:30 AM

Here are the most important beliefs of cybernetic totalism:

 

1) That cybernetic patterns of information provide the ultimate and best way to understand reality.


2) That people are no more than cybernetic patterns.


3) That subjective experience either doesn’t exist, or is unimportant because it is some sort of ambient or peripheral effect.


4) That what Darwin described in biology, or something like it, is in fact also the singular, superior description of all creativity and culture.


5) That qualitative as well as quantitative aspects of information systems will be accelerated by Moore’s Law.

 

And finally, the most dramatic:

6) That biology and physics will merge with computer science (becoming biotechnology and nanotechnology), resulting in life and the physical universe becoming mercurial; achieving the supposed nature of computer software. Furthermore, all of this will happen very soon! Since computers are improving so quickly, they will overwhelm all the other cybernetic processes, like people, and will fundamentally change the nature of what’s going on in the familiar neighborhood of Earth at some moment when a new “criticality”is achieved- maybe in about the year 2020. To be a human after that moment will be either impossible or something very different than we now can know.

Computational Linguistics of Twitter Reveals the Existence of Global Superdialects | MIT Technology Review | Science, Technology, and Current Futurism | Scoop.it

The first study of dialects on Twitter reveals global patterns that have never been observed before. A dialect is a particular form of language limited to a specific region or social group. Linguists are fascinated by dialects because they reveal social classes, patterns of immigration and how groups have influenced each other in the past. Bruno Gonçalves at the University of Toulon in France and David Sánchez at the Institute for Cross-Disciplinary Physics and Complex Systems on the island of Majorca, Spain, say they have found a new way to study dialects on a global scale using messages posted on Twitter. The results reveal a major surprise about the way dialects are distributed around the world and provide a fascinating snapshot of how they are evolving under various new pressures, such as global communication mechanisms like Twitter.
