When students encounter iPIN data scientists Online question and answer

The word we hear too much data, but few people realize that, with the development of Internet, nowadays these “big” words for what has meant a kind of level. Removed minority grandstanding of using this word of company outside, those real has big data of enterprise, handled and processing of are is some people may poor very life also contact not to of digital: micro-letter friends circle daily will upload 1 billion Zhang pictures, paid treasure day turnover peak over 20 billion Yuan Yuan, Beijing East daily upload millions of Zhang new of commodity information figure……

These figures are in urgent need of training artificial intelligence algorithm, it is very good news. Also means that the data is as important for artificial intelligence computing, algorithm development skyrocketed. But in a broad array of data to filter out those really useful for us? By analyzing these data to make decisions favorable to itself? This is the data the scientists doing the.

This issue hard to create open class, we invite to the iPIN Pan Rong, Chief Scientist, he received the doctor of Science degree from Zhongshan University in late 2004, in February 2005 and from August at the Hong Kong University of science and technology, respectively, in August 2007 and from September in the United States of HP Labs, data mining, artificial intelligence research. October 2009 through the hundred plans entered the Sun Yat-sen University, served in the Department of computer science. Chief Scientist, iPIN, 2014. Cath Kidston galaxy note 3 cover

Following is the AI technology review-June as we get our students a question and answer session.

Student 16: data mining is not a clearly defined subject, if we chose this approach, and what lessons should be compulsory? Elective courses?

Pan Rong: compulsory: (pre-courses in program design, data structures and algorithms, architecture, computer networks, and so on) probability and statistics, databases, machine learning and pattern recognition.

Optional: GPU/parallel computing, data warehousing, data visualization, deep learning, business intelligence (BI), swarm intelligence (CI), some courses for different application areas, such as information retrieval, NLP, speech, and image.

Student Jason: Pan teacher, I am a PhD candidate in accounting, to research a bit on the finance and machine learning applications. Don’t know the teacher do you think the future scenario of what?

Pan Rong: recommended system is an extremely practical issues, I suggest you’d better have enough data to start, it is best to have the cooperation of enterprises, it should be a very promising direction.

Student 16: ask the teacher pan, if you want to learn how to make a simple but full featured (functional) system should be carried out step by step how to? Mainly what variables are factors to consider, what data is collected, what algorithm to use, how to model and visualize?

Pan Rong: different recommended questions, data, modeling may be very different.

Students slightly coconut O.O: teacher, if fans want to learn data mining, personal PC’s performance be enough? How to resolve data source problem?

Pan Rong: getting started, personal PC is enough, unless you want to study.

Cath Kidston galaxy note 3 cover

Student YM: well you did you have any models in the source domain, similar to source domain the target domain behave badly? Is there a unsupervised or semi-supervised method for recommendations for the adjustment of the model of the target domain?

Pan Rong: this is often the case, you can refer to Yang Qiang teacher’s work in migration studies.

Student Adam.K: Pan teacher, may I ask you opinion about recently was very adversarial network, in the field of NLP: what? Cath Kidston galaxy note 3 cover

Pan Rong: I was very interested, GAN said it’s kind of magical, we now have his application in the field of NLP, but also very much looking forward to some things I think GAN is no breakthrough should have a chance.

New Apple patent: improving the map navigation with augmented reality experience

According to AppleInsider reported that Apple introduced today two new patent applications. According to the description of the application, it uses augmented reality to improve the performance of iPhone navigation. Combined with the iPhone camera and application to users based on the cover around the real, this technology can generate virtual map, to render the scene around the Interior of the building. Givenchy iPhone 6 Plus

The patented technology to GPS, WiFi and sensor data to pinpoint the user’s location, and then download a 3D model of the surrounding environment. But use sensor data may cause some errors, in order to bridge the gap between virtual scenes and real (drawing other augmented reality applications), Apple is using the iPhone camera to video broadcast, let users compare real and virtual elements included in the drawing. Once the match is successful, the user on the virtual image “piercing” building outer layer inside.

Apple has added a Flyover in the iOS map features, 3D satellite imagery for the virtual interactions more, but this time add the augmented reality (AR). Has also introduced similar features before, including Layar and other startups, but the launch of Apple’s patented technology is more sophisticated and practical.

Challenge Oculus Rift? Totem with a camera as well as augmented reality

In March this year, when established in Canada Montreal startup Vrvana announced that it will use its products Totem to the Oculus Rift challenges, a lot of people don’t think about this. This virtual reality headset is the biggest feature is that every time there is a camera in front of the eyes. Startup show Vrvana, apart from a few renderings and does not show how this device works, and they announced that also happens to be the time not long after Facebook announced the acquisition of Oculus. This attracted more rumors. Valentino iPhone 6s plus case

Some people think that the Totem was a vaporware (that is, declare in advance, development began to advertise the product, maybe these products do not come out), and still others say it is a scam. Valentino iPhone 6 plus case

By September, 6 months of time passed, Totem of the prototype EZ. Totem in the 2014 game developers Conference, made a brief presentation, after which the Vrvana won 350,000 dollars of financing, with this Vrvana can start producing Developer Kit and compete with the Oculus.

Challenge Oculus Rift? Totem with a camera as well as augmented reality

For Totem

Studied the various media reports, there is still no one has started to play the device, so for the published data still could not quite believe that, at least Vrvana Totem specifications look good. It is equipped with a 1080P full HD OLED display, HDMI interface, wide-angle horizontal angle up to 90 degrees.

Vrvana CEO Bertand Nepveu said in an interview from the broader context of the entire market, there is sufficient market space to add more virtual reality head-mounted display to compete in this market.

2 cameras installed in front of the Totem head-mounted display, both tracking the camera a full 360-degree, while its competitor Oculus can make a 180-degree location tracking. Vrvana States that are doing because a full 360-degree location tracking can be more accurate in the game move, and reduced delays (Oculus latest Crescent Bay supports 360 degree track). The two cameras also can let the players do not need to remove the head-mounted display you can see the real world, but in practical use, it may not be really (to pause the game to grab a bottle of Cola? )。

Totem has two cameras, so more exciting scene should be can be achieved using camera augmented reality (AR), game developers real world superimposed with the image on the monitor. Augmented reality and virtual reality technology fused together may be more difficult to imagine possible. Of course, since at the present stage of technical barriers, augmented reality and virtual reality in the actual use is still limited, at present this type of head-mounted display must also be connected to the data lines or power lines, that can only be used in a small space.

At present the project is above the Kickstarter to raise, supporters can get a Totem for $ 400 price, this product will ship in April 2015,. Wait until the official listed sale, at which time the product will retail for $ 549.

Lei feng’s network (search for “Lei feng’s network” public attention): author of soup, computer Assembly industry, proficient in computer hardware configuration.

Reading notebook thermal design and cooling techniques

Hot summer days, many notebooks began to transform hand warmers, especially students who hid in the bedroom playing games every day, no air conditioning at all overwhelmed. We touch briefly on thermal design for notebook and laptop cooling techniques.

Thermal design

virtual reality iPhone case

First of all, to talk about the notebook what thermal design, that is to say what kind of design can enhance the notebook cooling.

Tube: similar to the CPU and heat sink, notebook cooling by heat pipe, heat transfer to the fans at the (of course, also has a passive cooling of notebook, like the new Macbook). Since notebook needs are light, heat also made flat.

Reading notebook thermal design and cooling techniques

Other materials used and quantities other than mentioned before, of heat pipe in notebook layout, length, weight, greatly affect the cooling performance of notebook.

Layout test tube manufacturers in the design of the motherboard power, CPU and graphics card should be generally close to the cooling fan, heat quickly stretched to the cooling fan, should not be in the Middle near the heating elements such as memory, hard disk.

Reading notebook thermal design and cooling techniques

A pipe like this throughout the CPU and graphics design in a number of low prices will appear. This picture of laptops strung together two large fever, and then next to the memory, I am afraid, is to make artificial small Sun.

Reading notebook thermal design and cooling techniques

The length of the pipe should be as short as possible, it tube too long will result in low efficiency. Shorten the distance between pipe length to CPU fan on the one hand, on the other hand is a reserve position in board design, allowing tube to straight to the fan, a straight line between two points short. After the notebook apart there is a tube that winds like a snake inside, almost frenzied.

Reading notebook thermal design and cooling techniques

Like the pipe across the Pacific, return several small islands in the middle of heating, presumably for melting glaciers as a force.

The thickness of the pipe it is to say, in the case of the same thickness, thicker pipe with strong thermal capacity. The other hand, thicker pipe is guaranteed with the CPU and the fan with a larger contact area.

Fans: focuses on the number of fans here. Save for reasons of cost or is not doing design, some manufacturers are promoting a single show with only a fan, for mainstream gaming graphics card, is clearly not enough. Du said at the beginning of the game, dual fans three fans are even necessary. Separate CPU and video card cooling fan, can have better cooling effect.

Thermal dissipation space: mainly is the gap between the motherboard and the body. Greater thermal dissipation space can guarantee the smooth ducts, but also to sacrifice the thickness, so the game does a slim is not entirely a good thing. Look at Alienware heavy body to know that not only accommodates a wide range of high-performance hardware, and also provides a large space for heat dissipation.

Reading notebook thermal design and cooling techniques

Of course, also have the courage to challenge humans in the world, just performance hardware thin fuselage. Welcome, as long as the heat sink clearance, thin is even better.

Reading notebook thermal design and cooling techniques

Ventilation: ventilation holes into the wind, and the wind window, the theory is, the more the bigger the better. Of course, the ventilation holes not only into the wind, but also into the dust, dust control measures did not do so, ventilation holes once more, computer wall slightly.

Reading notebook thermal design and cooling techniques

Broad sense as long as they can access wind gap should be called the cooling vents, so it includes keyboard key gaps. Some products use the keyboard for the longitudinal thermal to achieve unexpected results.

Channel: vertical duct different from desktop, laptop thin fuselage duct design more dimensional, so as to enhance heat dissipation. In General, will take the plane into the wind at the end of the game, side and top air duct design, this is why you play the d face has a line of fresh air inlet.

Duct design and desktop is similar to portable duct should also follow the principles of wind to blow. Airflow should be continuous and orderly on one side and, on the other side. Some portable duct design chaos, wind blowing around, say no more.

Low density of cold air from the bottom into the controversial, do not consume too much of the location. Some scrupulous manufacturers will by means of joining stepping pad d ensure air inlet open. virtual reality iPhone case

Reading notebook thermal design and cooling techniques

By opening the hinge of the top fuselage design such as this are subtle, although I think a little ugly. Of course, there are also some notebooks in order to make integration of d, gave up the bottom air inlet, and moved to a different location, d is a complete plane, looks more beautiful.

Instead of blowing out hot air from the top side and trouble spots, because cooling vents requires no small locations, the most serious is the side of the connector. For this reason, many manufacturers are under the much elsewhere in the notebook holes, such as the previously mentioned keyboard slot. Such as high-end game common in the rear of the wind:

Reading notebook thermal design and cooling techniques

There are lunatic at the hinge of the wind, on a very tall:

Reading notebook thermal design and cooling techniques

Mac is that you like to do. But hinge out of the wind generally blows the screen, resulting in an increase in the temperature of the screen, is a hazard for high performance laptop.

There is a display of wind, such as Surface Book:

Reading notebook thermal design and cooling techniques

Oh yes, Surface Book there are both screen the wind shaft wind. Of course, the price of the wind is going to screen the screen can have some space for heat dissipation, so the thickness of the screen must be increased. VR iPhone case

Desktops duct often worry about how, heat, after all, space is very large, picked a radiator has a very powerful. Portable duct design is very important, notebooks, small spaces can lead to heat is out, other than the CPU and graphics card, hard drive and memory are computer generated heat, heat and they can only be fulfilled by the air flow in the duct.

Body material: this is something that many people tend to neglect, metal, plastics, fibers and other materials of the thermal effects are not the same fuselage material to some extent will affect the overall thermal performance of notebook. In theory, the metallic cooling effect should be better, but at the same time, heat to the metal after the hand is also very hot.

Heat source: duct design, no matter how good, there will be a very hot place, that is the source location. If you roll the beat, QWER found four fingers cooked, then prove you bought before the book did not make reference to the heating source. Heat source can be adjusted through the duct and motherboard designs, suggest that, particularly in a game before you buy, look it up on the Internet.

Reading notebook thermal design and cooling techniques

Of course, the heat source no matter how stressed that only in one point c, often meet, choice is not too critical.

Laptop cooling capacity will affect hardware run also greatly affects the experience of notebook, keyboard and trackpad are, after all, on top of the heat source. A really good laptop, not just performance screen, while at the same time there should be a good experience.

Cooling tips

If you have bought books, then there is no way, heat capacity was already doomed. But don’t lose heart, enhanced cooling techniques below may be able to help you.

Tube modification: heat part of the transformation, the simple thing to replace the grease, I here will say such a silly thing about it! So I picked one found online:

Reading notebook thermal design and cooling techniques

Water cooling notebook modified asks are you afraid! Heat transformation can be said to be the most interesting notebook DIY way, in addition to changing water so horrible, you can also consider tubular heating elements, heat adaptation, finning and other means.

Fan retrofit:

Openings for reform:

Duct improvement:

Cheapest air duct reconstruction is ash. Why is the cheapest, because of yourself you can do, take apart laptop and wiped, and then loaded on. Before you buy a notebook, look at the notebook did d simple cleaning Windows, lift the lid wipe it.

Of course, don’t need cleaning too frequently, generally one or two years at a time, the desktop is the same. Some CPU was murmur to higher than yesterday, and I don’t know what to say … …

Laptop-assisted radiator is another weapon, many students may have bought. Laptop-assisted radiator can be roughly divided into notebook cooling base and stroke type radiator.

Laptop cooling base is common, that is a shell of the fan. On one hand, the wind blows, the equivalent of air into the notebook on the other, elevate the d side of the notebook, makes it easier for air to enter.

Reading notebook thermal design and cooling techniques

This seemingly simple notebook cooling base, conspiracy and heavy, you may want to see before you buy:

Note d (that is, bottom) air inlet is not, buy it basically useless. Notebook Cooling base principle is to give d air inlet air supply, even the air inlet is not, is basically nonsense;

Location is not on the air inlet of the fan, bought basically useless. Buy when the pick is good;

Air pressure is not enough, is not to buy. Before testing, really saw notebook cooling base temperature rise. Notebook Cooling base of those more than 10 dollars, are really less the air conditioning more fierce.

Exhaust thermal artifact type radiator is recognized, through powerful for taking the notebook’s heat reach the cooling effect.

Reading notebook thermal design and cooling techniques

But it cannot be denied that certain ventilation radiator is a very low price of chicken. Exhaust radiators also have compatibility problems, but rubber ring seal product has become popular, a big problem. But also a few of the most serious problems of noise, a little with thousands of fans in the ears, really very ventilation.

Don’t forget, if you side not cooling vents, you can also go, contents of the ventilation is not so good.

About duct, another point to remind the notebook keyboard membrane. Mentioned some products through the keyboard slot heat sink, if you buy a rubber keypad membrane covered, the equivalent of road, blocking the wind, of course, is very bad. If you are obsessive-compulsive, or love sloppy often chips off soda sprinkled on the keyboard on the keyboard, you can consider buying a breathable fabric or nylon membrane keyboard.

Remove the external solution, you may wish to see a power settings in the Control Panel, you can set your computer’s power supply mode, slightly downwards, to a certain extent reduce the heat of CPU and graphics card.

The other hand, notebook fever is normal. Desktop may have a fever, but you don’t touch it so I can’t feel it. Fever is a normal phenomenon, not to be so nervous. If you stand there are forty or fifty degrees, it really had to be alert to … …

Hendo hanging skateboards: the world's first to fly you skateboard

Arx Pax company based in California, are raising their own Hendo hanging skateboard. Hendo not entirely like the back to the future in the Martin flying skateboards to use when, precisely, Hendo is suspended–skateboarding pioneer in the field of product users capable of autonomous driving, self-propelled, floating platform powerful enough to support an adult’s weight.

When a user in the initial pilot, will cast doubt on its load-bearing capacity. Arx Pax said Hendo enough now version supports more than 130 kilos in weight, and released a new version in the future, this figure will increase to more than 220 kilograms. But no matter what the result, hanging skateboards made of the primary question is, it has to be suspended above the surface in a specific, can realize the function of host objects. Hendo used the same and Maglev technology, which means that it can only float in non-ferrous metals (other than iron or steel), such as copper or aluminium.

Hendo hanging skateboards: the world's first to fly you skateboard

In actual operation, due to lack of propulsion systems, Hendo trajectory is more like aimless drifting and Martin flying skateboards, can’t do that. Arx Pax founder and inventor Greg Hendo Henderson said, the company is working on by tilting suspension skateboard to control the direction of Hendo. But the reality is, because of the friction and do not feel the ground, difficult for users to control the operation of size, need to be used more than once to use.

Hendo hanging skateboards: the world's first to fly you skateboard

Hend’s original inspiration from the architecture. Greg Henderson says, “If you can get the train load of 50,000 kg suspension on the ground, so a House can become possible. “He subsequently explained, suspended building is a long-term goal, the current technology is still in its early stages of development. When the earthquake came, the building from the Foundation “lifting” and minimize the loss of natural disasters, it is the effect of the emergency safety systems need to be in the future. Modern suspension technology is still in its early stages, Henderson and his team will be ideas from concept to reality. Hello Kitty iPad Air

Hendo hanging skateboards: the world's first to fly you skateboard

On the Kickstarter, at $ 299 to get Hendo hanging skateboard complete engine modules they want users hanging skateboards to create more of the suspended projects, Arx Pax company also will subsidize the creativity to turn it into reality. $ 100 can get 5 minutes to hang skateboards prototype experience; back in under the guidance of a personal trainer and $ 1000 for 1 hour only ten sponsored 10,000 supporters can really have a skateboard. Product release date is October 21, 2015-Martin back in the years to come. Hello Kitty iPad
