Company Note: Baidu
Baidu derives its revenues primarily from the following sources:
1. Online marketing services - This accounts for the majority of Baidu's total revenues. Baidu delivers online marketing services through its network of third-party agents and direct sales team to a diverse customer base. The online marketing services include P4P (pay for performance) services where customers bid for priority placement of paid sponsored links, as well as other marketing services.
2. Others - This includes revenues from Baidu Core businesses such as the Mobile Ecosystem (apps like Baidu App), AI Cloud (enterprise/public sector cloud and personal cloud services), and Intelligent Driving & Other Growth Initiatives (Apollo intelligent driving, DuerOS smart assistant, etc.).
Regarding AI work, Baidu has been investing heavily in AI research and development since 2010. Some key points about Baidu's AI efforts:
* Launched ERNIE Bot, a conversational AI assistant powered by Baidu's ERNIE foundation models, in early 2023. Released updated versions ERNIE 3.5 in May 2023 and ERNIE 4.0 in October 2023.
* Developed AI chips like Baidu Kunlun and Baidu Honghu to support cloud, smart devices, and vehicle applications.
* Created PaddlePaddle, an open source deep learning platform.
* Applying AI in areas like autonomous driving (Apollo), smart assistant (DuerOS), and cloud solutions for enterprises/public sector.
So in summary, while online marketing still drives the majority of revenues, Baidu is leveraging its long-term investments in AI to expand into new business areas and drive future growth in the Baidu Core segment.

Artificial Intelligence & Machine Learning
Across the entire time period, a major focus of Baidu's R&D efforts has been on artificial intelligence and machine learning technologies.
This includes work on:
* Foundation models, large language models and generative AI (ERNIE Bot, ERNIE 3.5, ERNIE 4.0)
* Multimodal AI models that combine language, vision and speech
* Neural networks and deep learning model architectures
* Adversarial training methods to make AI models more robust
* Efficient AI model compression and acceleration techniques
* Applications of AI to domains like speech recognition, computer vision, video understanding, question answering, etc.
From 2022-2024 there seems to be an increasing emphasis on foundation models, large language models and generative AI capabilities. Recent patents discuss Baidu's ERNIE Bot and more advanced ERNIE models.
Autonomous Driving
Another major long-term focus area for Baidu R&D is autonomous driving technologies. Over the years, patents cover:
* Perception and sensor fusion for self-driving cars
* AI planning and decision making for autonomous vehicles
* High definition mapping and localization
* Simulation environments for testing autonomous driving
Moreover in 2022-2023, there was work done on improving the robustness and efficiency of autonomous driving software and hardware.
Other Notable Areas:
* Search and information retrieval - improving web search, entity linking, knowledge graphs
* Recommender systems and personalization
* Healthcare AI applications
* Speech interfaces and emotion recognition from speech
* Computer vision for facial recognition, object detection, etc.
* Cloud computing infrastructure
* Hardware for AI acceleration
Bottom Line
Baidu has maintained a strong focus and active development in core AI technologies and applications over many years based on its patent portfolio. In recent years, larger AI models, generative AI, efficient deep learning and autonomous driving seem to be increasing areas of R&D investment. Baidu continues to leverage AI to enhance its products in search, recommendations, speech interfaces, computer vision and other domains.
