As the focus of this forum, Wu Tian officially released the knowledge map and intelligent creation platform 2.0. She said that the industry knowledge card platform is to solve the industry's need for knowledge building and knowledge application in the intelligent process. Basically, the intelligent creation platform is reorganization and reprocessing of information. Through basic techniques for natural language processing and knowledge mapping, a large amount of original information is deeply understood and logically analyzed to form the knowledge map and the material needed for creation. The library can give the creators the opportunity to mount, correct and polish the color in the written stage of the creation. Intelligent Authoring Platform 2.0 has three new features: real-time hotspots associated with rich materials, comprehensive creative help features, and leading generation technology.

Hot automatic machine learning

With the hard automatic machine learning, Baidu has taken the latest part of this technology.

Bai Jun, head of Big Data Lab, said there are three key technologies for autonomous artificial intelligence: custom networking design, adaptive and self-adapting the computing environment. AutoDL 1.0 shows that deep learning is comparable to human experts, and AutoDL 2.0 demonstrates Deep Learning has already outperformed human experts, and AutoDL 3.0 has been completely upgraded from design, migration and customization. In the design of AutoDL, Baidu proposed styleNAS (style migration with neural network structure search), which can greatly simplify the calculation and improve image quality.

He then mentioned some typical application scenarios of automated modeling, such as semantic segmentation, target detection, image classification, etc., such as garbage selection, and the camera is placed in the water to detect fish for ecological protection. In addition to a series of visual applications, he also mentioned the application of Baidu-automated modeling in NLP. In the Chinese emotional classification task, this technique achieved the same precision as expert manual setting, but greatly saved labor. .

Baidu speech technology interpretation

During the convening of this developer conference, we also saw many breakthroughs that Baidu made in voice. Gao Liang, senior manager of Baidu's voice technology department, introduced Baidu's three major technical breakthroughs in voice. He looked forward to Baidu's progress in speech recognition technology from 2012 to the present. With the continuous improvement of the model, the accuracy becomes higher and higher.

He focused on the multilevel SMLTA flow, the truncation attention model, which is the first time in the world to achieve local attention model in addition to the entire attention model, and also the first international attention model for large-scale voice usage, whether input it is still in the speaker, and the relative accuracy of the effective products can be greatly improved.

Later, he emphasized the MEITRON style migration technique, hoping that the speaker could convey more information beyond the text but faced three challenges: style migration, tone simulation, emotional anthropomorphism, especially as the ability to personalize the tone, Can express meaning other than words, such as happy, sad and others feelings. MEITRON can output three independent networks of timbre, rhythm and emotion through spatial modeling of several sentences. He said the network uses unattended training and does not require massive amounts of data to enable dynamic classification.

As for the technical details of Baidu Hongjun's intelligent voice chip, he also provided a detailed explanation on this forum. The chip is suitable for scenarios for speech field interviews, which support the high degree of parallelism between the deep learning calculation and the depth model load.

He said "Dr. Tea" in the main forum in the morning is a combined AI capability, including multimotor dialogue understanding, multi-candidate generation, location-sensitive reference elimination, multi-dialogue dialogue status update, and Action triggered. Based on Baidu 3D vision, the robot can perform carpet detection and position tracking. Based on robot pipe planning and control, the robot arm can detect collisions in the work surface and avoid obstacles. After the real-time planning time, the robot can automatically generate the teban. Then the robot can sense the change in the water flow and adjust the position in real time. He said that AI technology will no longer be an island in the future, and the combined AI will promote the development of construction machinery and other applications.

Li Ying, head of the Baidu Maps Division, took a smart estimate of Baidu card transit time based on aircraft. She said that a new generation of artificial intelligence maps combines different techniques such as speech, AR and high quality knowledge maps.

Estimated arrival time (ETA) is the main feature of mapping planning and an important reference factor for users' travel decisions. With this technology, users can avoid overload periods, understand overload times, and avoid overload routes while traveling, but also face many challenges and difficulties, such as major changes, many factors, high timeliness, and strong personalization. Based on this, they proposed a deep neural network computational model, based on the aircraft platform, which can realize real-time ETA accurate estimation and overload of road time calculation. The model combines multi-layer coding and multi-layer sensing.

Finally, Guo Xie, senior manager of Baidu's large data department, introduced the introduction of Baidu's large platform platform.
