#How was ChatGPT trained by a hundred study clubs? After so many years of development, with the advent of ChatGPT, artificial intelligence seems to have entered an era of explosive growth. Artificial intelligence has gradually begun to disrupt various industries and change their work modes. So how did such a smart and powerful artificial intelligence be trained? In this issue, we will talk about the training methods of artificial intelligence.
If you want to learn more about expanding knowledge points, Baidu can search for "neural networks" to obtain more related information. There are many neural networks in the training of artificial intelligence, which ultimately imitate human learning methods and attempt to simulate the working mode of human neural networks to design and manufacture artificial intelligence. However, due to the slow progress of research on the brain, current technology has not fully understood the working principle of brain neurons, So currently, neural networks are mostly modeled after neural networks, imitating human learning methods to achieve training results.
We know that the way humans learn is by repeatedly memorizing knowledge and establishing connections between them, forming a knowledge system. When faced with a problem, the pattern of artificial intelligence is similar by extracting the knowledge system to solve the problem. However, they repeatedly train the same type of data, and then record a specific set of data in each unit of the neural network. When the demand arises, Calculate each unit to output the final result.
In this process, each unit has its own weight value and offset value. By calculating these two values and input data, for example, there is a circuit board filled with light bulbs and wires. Through training, the brightness and position of the light bulbs can be adjusted, and finally the light bulbs can achieve their function, which is to present a certain pattern.
The specific training process is also similar to that of artificial intelligence training methods that humans are taught to learn: supervised learning, like a strict teacher, will provide input data and correct output data to the circuit board, such as giving it a picture of a cat and a "cat" label, so that it can learn how to identify animals on the picture.
Then, the circuit board will continuously adjust its small light bulb and wiring to make its output data as close as possible to the correct output data. If the output is correct, the teacher will give praise; If the output is incorrect, the teacher will criticize it, and the circuit board will gradually master the skills of recognizing animals. This training method is represented by convolutional neural networks.
Unsupervised learning is like a laissez faire parent who will provide input data to the circuit board but not correct output data, such as giving it a pile of pictures, but not telling it what is on the picture. Then the circuit board will find the rules and characteristics in the input data itself, and carry out some classification or clustering operations. For example, the circuit board can distinguish what objects or scenes are in the picture by itself, Or group similar images together.
In this way, the circuit board will gradually extract the essential information of the data. This training method is represented by generative adversarial networks
Semi supervised learning, like a gentle tutor, will provide the circuit board with some input data with correct output data and some input data without correct output data, such as some pictures with text descriptions and some pictures without text descriptions. Then the circuit board will use labeled data to guide the learning of unlabeled data.
For example, the circuit board can generate appropriate text descriptions for pictures without text descriptions by learning pictures with text descriptions. In this way, the circuit board will make full use of all data resources. The representative of this way is to train the generative model to strengthen learning. Like an incentive coach, he will let the circuit board obtain feedback information through interaction with the environment, and adjust his behavior strategies according to the feedback information, To achieve a goal or maximize a reward.
For example, by having a circuit board play a game and adjusting its gameplay based on scores or failures, the circuit board will continuously explore and try to find the optimal solution, represented by a deep Q network
Overall, artificial intelligence is a training method that imitates human thinking. Through this method, artificial intelligence can play a role in various fields such as healthcare, education, entertainment, and contribute to human life. In the face of artificial intelligence, we should actively embrace it as a tool to take advantage of it. So, what do you think is the gap between artificial intelligence and human thinking?.
