Ren Pingping: The real artificial intelligence explosion is coming soon
Ren Pingping, Marketing Director of HKUST, pointed out at the forum that with the introduction of the concept of deep learning in recent years, the successful application of DNN in speech recognition technology in 2012, and the application of CNN in image recognition in 2012, and machine translation in 2014 In the application, breakthroughs in deep learning, machine translation and image recognition, as well as our big data, our computing power is constantly strengthening, we feel that the real artificial intelligence explosion is coming.
The following is a speech record:
Thank you all, I am honored to be invited by the college to share with you the topic of artificial intelligence. We know that the breakthrough in biomedicine will make people’s life expectancy exceed 100 years old. The breakthrough of artificial intelligence technology will make our simple and repeated labor will be With the replacement of machines, people's lives will get better and better.
To what extent is the current artificial intelligence technology going? What technologies and which applications have breakthroughs? I want to stand in the perspective of the company, we have also made some attempts to share with everyone.
When it comes to artificial intelligence, we have to look back at the Dartmouth conference 60 years ago. Today we all say the 60th anniversary of artificial intelligence. There have been several ups and downs in this 60 years. For example, the golden period of the second artificial intelligence is the 90s, 90 In the era, due to the development of information technology, everyone's problems were solved. Similarly, artificial intelligence did not reach the height that everyone wanted.
With the introduction of the concept of deep learning in recent years, the successful application of DNN in speech recognition technology in 2012, and the application of CNN in image recognition in 2012, and the application in machine translation in 2014, in deep learning, machine translation and image Identification and other technological breakthroughs, as well as our big data, our computing power is constantly strengthening, we feel that the real artificial intelligence explosion is coming.
In fact, it is not only that we mention this, China’s academic circles are mentioning this, the industry is mentioning this, and everyone in the world is saying that there are ten economic technologies in the 2016 World Economic Forum. Everyone mentioned the ecology of AR, in the artificial In the smart century-old research, Stanford has a report that also suggests how artificial intelligence will have to do with our lives in 2030. We think that artificial intelligence is faster than we think. A report from McKinsey mentioned that 45% of our work will be replaced by machines. Even 20% of the CEO's work will be replaced by robots. I will not say all the reports on the report. It is.
We feel that the development of artificial intelligence has gone through three stages. The first stage is what we call the arithmetic intelligence stage, which is the ability of computer computing and storage. The second is the stage of perceived intelligence. We will let the computer speak. Just like Obama, speaking English, Chinese, and the future, there are many languages ​​such as Korean and Japanese. It not only supports our Mandarin, but also supports more than 30 dialects. The foreign language will understand in the future. This is the second. Stages. At the end of the day, artificial intelligence will definitely enter the stage of cognitive intelligence. It can not only listen, but also understand and think, and will help us to do more and more complicated work.
I talked about the three stages of artificial intelligence. In fact, there are some breakthroughs in core technology in the development of artificial intelligence. Next, I will share some core technologies for everyone.
The first technology we talked about must be the human-computer interaction technology with voice as the entrance. It has the recognition of sound, the reasoning of learning, etc. First, let’s look at the technology of speech synthesis. The synthetic technology is just the voice of Obama. It has been intuitively felt for everyone. In some of our past competitions, we have won a championship called Natural Synthesis for 11 consecutive years. In this competition, there are American MIT and so on. Xunfei has a data that is more fun. We have participated in the seven consecutive years. The organizing committee changed the rules. We are no better than Chinese. We are better than Henry. We still won the championship.
In addition to the synthesis, we also talked about recognition. The recognition technology has also made a big breakthrough. This morning, we showed our main recognition technology in the main forum of our New Year Forum. The recognition technology now has a continuous speech recognition rate. If it is a Mandarin level, it can reach more than 95%. In fact, we did a comparison with the stenographers in December last year. We found five industry-senior stenographers and our machines for PK. The result of PK is that the accuracy of the short-spoken transfer in one hour can reach 70. %, the machine can reach 90%.
In the same way, we will release some recognition rates in the case of noise in the global anti-noise situation in addition to our hearing and rewriting in December. In normal times, it is relatively quiet, and it is recognized in noisy environment. How is the rate, and so on a series of games.
Mixed Assembly
What is PCB SMT assembly?
With the development of electronic technology, the demand for HDI PCB and High Frequency Board has increased. In order to reduce the cost of PCBA Manufacturing, more SMT chip technology is now being purchased. SMT patch refers to the abbreviation of a series of technological processes that are processed on the basis of PCB, and PCB (Printed Circuit Board) is a printed circuit board. SMT is surface mount technology (Surface Mounted Technology) (abbreviation for Surface Mounted Technology), and it is the most popular technology and process in the electronics assembly industry. It is a kind of surface assembly Electronic Components (SMC/SMD for short, chip components in Chinese) that are mounted on the surface of a printed circuit board (Printed Circuit Board, PCB) or other substrates without leads or short leads. Circuit assembly technology in which reflow soldering or dip soldering is used for soldering and assembly. Under normal circumstances, the electronic products we use are designed by PCB plus various Electronic Components such as Electronic Resistor And Capacitor according to the designed circuit diagram, so all kinds of electrical appliances need various smt patch processing techniques to process.
1. Silk screen: Its function is to leak solder paste or patch glue onto the PCB pads to prepare for the soldering of components. The equipment used is a screen printing machine (screen printing machine), located at the forefront of the SMT production line.
2. Dispensing: It is to drip glue onto the fixed position of the PCB board, and its main function is to fix the components on the PCB board. The equipment used is a glue dispenser, located at the forefront of the SMT production line or behind the testing equipment.
3. Mounting: Its function is to accurately mount the surface mount components to the fixed position of the PCB. The equipment used is a placement machine, located behind the screen printing machine in the SMT production line.
5. Reflow soldering: Its function is to melt the solder paste, so that the surface assembly components and the PCB board are firmly bonded together. The equipment used is a reflow oven, located behind the placement machine in the SMT production line.
6. Cleaning: Its function is to remove the solder residues such as flux that are harmful to the human body on the assembled PCB board. The equipment used is a washing machine, and the location may not be fixed, it may be online or offline.
7. Inspection: Its function is to inspect the welding quality and assembly quality of the assembled PCB board. The equipment used includes magnifying glass, microscope, online tester (ICT), flying probe tester, automatic optical inspection (AOI), X-RAY inspection system, functional tester, etc. The location can be configured in a suitable place on the production line according to the needs of the inspection.
8. Rework: Its function is to rework the PCB boards that have failed to detect faults. The tools used are soldering irons, rework stations, etc. Configured at any position in the production line.
