The DJI Mavic Pro

DJI slammed it’s Foldable convenient drone “The Mavic Pro” this week making it one of the best foldable, convenient drones in business, after the much-anticipated drone “Karma”, from GoPro was launched last week.

The Mavic Pro is tiny, foldable and can be carried around in your pocket (A big one), belt, there’s a clip which fits around your phone so you can still see the video from the drone, but it doesn’t require either that massive controller from the Phantom range, which seems to make sense for travellers who want to take their drone everywhere with them.

With the latest in tech, DJI includes a 4k camera stabilized by a 3-Axis gimbal and automated features like collision-avoidance, TapFly, and precision hovering all powered by a 24 core custom made processor. The DJI Mavic Pro can also be controlled with gestures and take selfies. Wave your hands to get the drone’s attention. Throw your arms up in a big Y and it will focus on you. Make a frame in front of your face with your hands and it will start the timer for an aerial selfie.

Flight time is 27 minutes and can exceed 40 mph in “Sport” mode. DJI says it can stream live video from up to 4.3 miles away, compared with a maximum range of 3.1 miles on the Phantom 4. The new system also promises to live stream 1080p video to services like YouTube, Periscope, and Facebook, compared to the 720p video on the latest Phantom. The DJI Mavic Pro can also be used in “first person” mode, which uses a set of goggles to allow you to fly the drone as if you were an aircraft pilot.

The Mavic Pro can be yours from 15th October for $749 and alongside with controller will cost $999. Of course, the Mavic Pro can be controlled using your smartphone too to steer.

Deep Neural Nets and The Universe

Neural Networks are extremely good at solving complex problems and their secret for this is buried in the laws of physics as said by physicists.

Deep learning techniques are used in Artificial Intelligence in areas such as face recognition, object recognition and also mastered the ancient game of Go. Neural Nets have achieved great success and nobody’s sure how they have achieved it. There is no mathematical reason why networks arranged in layers should be so good at these challenges.

Today that changes thanks to the work of Henry Lin at Harvard University and Max Tegmark at MIT. These guys say the reason why mathematicians have been so embarrassed is that the answer depends on the nature of the universe. In other words, the answer lies in the regime of physics rather than mathematics.

Consider an example of classifying a megabit grayscale image of determining whether it’s a dog or cat. Now such image is consisting of a million pixels that can each take one of 256 grayscale values. So in theory, there can be 2561000000 possible images, and for each one, it is necessary to compute whether it shows a cat or dog. And yet neural networks, with merely thousands or millions of parameters, somehow manage this classification task with ease.

Now, the Neural Nets work by approximating complex mathematical functions to simple ones.

The problem is that there are orders of magnitude more mathematical functions than possible networks to approximate them. And yet deep neural networks somehow get the right answer.

The scientists have worked out why. The answer is that the universe is governed by a tiny subset of all possible functions. In other words, when the laws of physics are written down mathematically, they can all be described by functions that have a remarkable set of simple properties.

So deep neural networks don’t have to approximate any possible mathematical function, only a tiny subset of them. To put this in perspective, consider the order of a polynomial function, which is the size of its highest exponent. So a quadratic equation like y=x2 has order 2, the equation y=x24 has order 24, and so on.

The laws of physics have other important properties. For example, they are usually symmetrical when it comes to rotation and translation. Rotate a cat or dog through 360 degrees and it looks the same; translate it by 10 meters or 100 meters or a kilometer and it will look the same. That also simplifies the task of approximating the process of cat or dog recognition. These properties mean that neural networks do not need to approximate an infinitude of possible mathematical functions but only a tiny subset of the simplest ones.

There is another property of the universe that neural networks exploit. This is the hierarchy of its structure. “Elementary particles form atoms which in turn form molecules, cells, organisms, planets, solar systems, galaxies, etc.,” say Lin and Tegmark. And complex structures are often formed through a sequence of simpler steps.

This is why the structure of neural networks is important too: the layers in these networks can approximate each step in the causal sequence.

The Boosted Board 2

Boosted board lately announced their next generation Boosted Board 2. For those who don’t know, electric skateboards are on the rise as a new way of commuting in the city. The boosted board 2 is extremely useful in the city as it reaches a top speed of 22 miles.

So what’s new in the Boosted Board 2 ?!

  • Increased Battery Life -There are now two battery options, both swappable in minutes so you can choose the range you need. The standard 99 watt-hour battery averages 6-7 miles (10-11 km) of range and is air-transport certified. The extended range 199 watt-hour battery averages 12-14 miles (20-22 km) while adding an incredibly light 0.75 lbs (340 g) and slim 0.3 in (8 mm) to the battery enclosure. Neither affects the bamboo deck’s flexibility and handling.
  • Water Resistant Housing – The battery, electronics, and motors are now shielded against water damage, so puddles and damp conditions won’t damage them.

  • Updated Wheels, Trucks, Motor, and Transmission – The board is still based on the amazing Loaded Vanguard deck. The Orangatang wheels are now 80mm for a smoother ride, and the trucks are now custom for improved carving. Upgrades to the motors and transmission have resulted in more motor torque, cooler operation, lighter weight and easier maintenance. Our belt drive transmission still multiplies motor torque by 3x, giving you better braking, acceleration and hill climbing.

  • Radio Connectivity Improvements – The Bluetooth radio that connects the board to the remote is upgraded for improved signal strength and security with ride tracking.
  • Accessory Port Added – A high-power, water resistant port can now be used to power external accessories like onboard headlights, taillights and charging ports.
