On June 14, baidu digital man Du Xiaoxiao and Gong Jun digital man jointly sang the song "every minute, every second, every day" on the whole network. This is the first virtual idol aigc (AI generated content) song in China, which is "manipulated" by AI from lyrics to music arrangement. As the first interactive virtual idol in China, Du Xiaoxiao can provide users with full AI chat function in Baidu app to upgrade the search experience. Behind this is the powerful underlying capability provided by Wenxin big model. "Users can directly initiate chat needs through the search box or the voice button at the bottom of Baidu app, and then they can call Du Xiaoxiao or Gong Jun digital people on the lower ground floor for real-time dialogue." Du Xiaoxiao's product principal said that at present, Baidu's AI digital people can mainly realize four functions, namely personalized chat companionship, auxiliary search, service distribution and interactive play. In the dialogue with users, baidu AI digital people will make relevant replies around their own "personal settings" in combination with the context, realize multiple rounds of dialogue, and support diversified chat forms such as text, audio, pictures, expression packs, etc; When the user's intention to search information is identified, AI digital people will directly reply to the answer or present the search results of relevant questions in Baidu app; When users express their service needs such as watching movies and booking tickets, AI digital people will jump to the corresponding service interface for users; In addition, it can also realize interactive entertainment functions such as story telling, joke telling, and unfashionable love talk. It is reported that Du Xiaoxiao can realize natural multiple rounds of chat interaction, and identify users' search and service needs in the dialogue. Behind this is the powerful underlying technical support provided by Wenxin big model. Specifically, it is the world's first large model of generative open domain dialogue based on hidden space. Wenxin Plato is a Chinese English dialogue pre training generation model with large-scale parameters developed by Baidu. After many upgrades, it has been upgraded to the 10 billion parameter Wenxin Plato version, which has continuously improved the effect of open domain dialogue. The dialogue technology based on Wenxin Plato has won 11 World Championships in the international authoritative dialogue competitions dstc9 and dstc10. It has the ability of multi round chat close to the level of real people. The model has reached the world leading level in various indicators such as dialogue rationality, richness and attraction. How to realize multiple rounds of smooth dialogue close to the level of real people? It is reported that Wenxin Plato first needs to pre train the dialogue model on the large-scale dialogue corpus to learn the general dialogue generation ability; Then, by fusing the portrait information, the dialogue generation ability under different portrait information is further learned on the basis of pre training the dialogue model, so that the model has the ability of human setting and consistency of response; Finally, the question and answer generation task and the pre training dialogue task are used for continuous pre training to internalize a large amount of question and answer knowledge into the model parameters, so that the Wenxin Plato has accurate knowledge question and answer ability and realizes knowledge enhancement. The application of Wenxin Plato in digital people such as Du Xiaoxiao has brought users an intelligent and smooth dialogue experience, which has shown its value in emotional companionship, Knowledge Q & A and other aspects. Baidu digital people have higher "IQ" and "EQ". In recent years, AI technology has been upgraded and iterated at a high speed, and the strength of aigc has become more and more intuitive in front of the public. Since June this year, Du Xiaoxiao, a Baidu digital man based on the Wenxin model, has intensively demonstrated his ability to write, paint and write songs, and has been highly praised one after another. As a part of the "infrastructure" of artificial intelligence, the large pre training model broadens the coverage of artificial intelligence technology landing scenarios and reduces the difficulty of penetrating into industrial applications. In addition to the direction of aigc, Wenxin big model has been applied to Baidu feed flow, smart speakers and other Internet products, and has been implemented in the intelligent transformation and upgrading of industries such as industry, energy, education, finance and communication. It is understood that Baidu has recently launched a new Wenxin · mingu community, a creative community of Wenxin big model, hoping to make more users feel the charm and application innovation potential of Wenxin big model from zero distance. In the future, aigc based on Wenxin big model will bring more innovative explorations and open empowerment to more fields. (Xinhua News Agency)
