Wide models are great for memorization, deep models are great for generalization — why not combine them to create even better models? In this talk, Heng-Tze Cheng explains Wide and Deep networks and gives examples of how they can be used.

Black holes are among the most fascinating objects in the known Universe. But despite the fact that they’re suspected to lurk at the centre of most galaxies, the reality is that no one has ever been able to actually photograph one.
That’s because black holes, as their name implies, are very, very dark. They’re so massive that they irreversibly consume everything that crosses their event horizon, including light, making them impossible to photograph. But that could be about to change, when a new telescope network switches on in April this year.
Called the Event Horizon Telescope, the new device is made up of a network of radio receivers located across the planet, including at the South Pole, in the US, Chile, and the French alps.
The old joke in the US Natl. Labs is if you worked at ORNL, you glowed at night. Looks like DARPA has found a safer way to do it.
Timothy Blake, a postdoctoral fellow in the Waymouth lab, was hard at work on a fantastical interdisciplinary experiment. He and his fellow researchers were refining compounds that would carry instructions for assembling the protein that makes fireflies light up and deliver them into the cells of an anesthetized mouse. If their technique worked, the mouse would glow in the dark.
Not only did the mouse glow, but it also later woke up and ran around, completely unaware of the complex series of events that had just taken place within its body. Blake said it was the most exciting day of his life.
This success, the topic of a recent paper in Proceedings of the National Academy of Sciences, could mark a significant step forward for gene therapy. It’s hard enough getting these protein instructions, called messenger RNA (mRNA), physically into a cell. It’s another hurdle altogether for the cell to actually use them to make a protein. If the technique works in people, it could provide a new way of inserting therapeutic proteins into diseased cells.
More on the new bio-robots.
SCIENTISTS have created flesh-like mini-robots that can move when they detect light.
The fleet of walking “bio-bots” are powered using muscle cells and controlled using electrical and optical pulses.
The Sun reports the sinewy robots are less than half an inch long and are made from 3D-printed hydrogens and living cells.
We have stated this for a while; time to make it commercially available.
Our bodies are full of immune cells that circle around the blood, ready to see off any invaders.
And soon they could be getting a helping hand from tiny disease-fighting robots.
Scientists have created an army of magnetically-controlled robots which they say could help our bodies fight off diseases such as cancer.
Nice. My friend Alex Zhavoronkov will appreciate this article.
Feb. 16 (UPI) — Researchers at McGill University in Montreal have found that targeting the internal circadian or biological clock of cancer cells can affect growth.
Most cells in the human body have an internal clock that sets a rhythm for activities of organs depending on the time of day. However, this internal clock in cancer cells does not function at all or malfunctions.
“There were indications suggesting that the malfunctioning clock contributed to rapid tumor growth, but this had never been demonstrated,” Nicolas Cermakian, a professor in the department of psychiatry at McGill University, director of the Laboratory of Molecular Chronobiology at the Douglas Mental Health University Institute and author of the study, said in a press release. “Thanks to the use of a chemical or a thermic treatment, we succeeded in ‘repairing’ these cells’ clock and restoring it to its normal functioning. In these conditions, tumor growth drops nearly in half.”
