Conference: "21st century computing" Assembly Nanjing
I want to talk about what we've been doing research on organic interface.
In the computer language generation, the computer will not only be able to identify a large vocabulary, but you can also slice of vocabulary, you can spell synthesis "computer science" such a Word, but it sounds very natural. But today our system, you give it compared with human capabilities, its performance is still not quite ideal. In a different voice environment, one can identify all of the language and discourse, if you put a person's performance compared with the performance of the computer, you will find, is basically also are two orders of magnitude difference. This is our very worried, how to build more like people, more perfect system? today I want to provide a more unique perspectives, it will make our computer any new changes.
We establish the system will consider whether it can have the cognitive ability, like a life-like existence.
They can observe, can grow to heal themselves, is the so-called cognitive computing, organic calculation. In the past, we only focus on independent application, the application can now computers are increasingly and human interaction. In the past we are binary, not in the wrong, black or white. However, we may not necessarily know what is wrong is right, we need multiple standards by making a choice. Therefore, the question now is on the computer system, the operating environment is filled with a variety of uncertainties, human behavior, we cannot fully interpret. Sometimes we have to deal with one-sided information, but also to arrive at better solutions, we have to rely on machine learning techniques, and probabilistic techniques.
What is organic? in short, it is handled by the system (including software and hardware), you can observe their run-time behavior and, over time, based on their observation to make change.
So in this process, there are some features that might be a target-oriented, you tell the computer what you want to do, the computer will make changes, he must be on its own, to find out what to do now, as well as your goals and his status of gap, at the same time try to pass their adapted to reduce the gap, final action, this system must be able to repair themselves. Organic systems must have certain properties, such a system must be energetic, able to adapt to changes in the environment. In addition the system must have the ability to learn, but he must have the ability to learn, he must have the ability to observe, to be able to understand his this environment has changed. At the same time he wanted on his surrounding environment conscious, both through their own lessons to learn, but he must continually adjust themselves, based on their observation to adjust their own. Computer learning, self-regulation of the computer, as well as on environmental observation, is the essence of our organic system.
In addition, I will briefly discuss the application of video symbiosis.
People in communication with Visual and auditory two channels, you can use these two aspects to do many things, for example, I see a person's face, I knew this guy; I listen to his voice, you can know who he is; even his walk, I can recognize him. So we have to do is, you want to identify a person, you can use voice or Visual; you have to understand the meaning of his words, you can see his mouth, etc. In addition we also have some facial expression, tone indicates the language used in the feelings, so it is necessary to establish the interface, the integration of all things. For example, to log into a system, through the voice of a person's head and to identify, only two anastomosis can login system, if this person's face and his voice is not satisfied, he will be unable to login to this system. Of course you can also put our language and Visual integration of information, but in a very noisy environment comprising the realization of our recognition.
Overall, we have made organic interface considerable progress.
Man-machine interface is a kind of organic capacity of the organism, it can observe, you can learn, grow, and can be cured. We have many challenges is not complete, look forward to all the students go to overcome them.
