Artificial intelligence (AI) expert Andrew Ng has announced that he is resigning from his role as chief scientist at Chinese search engine giant Baidu after nearly three years in the job.

Ng, who announced his departure in a blog post on Wednesday, does not currently have another job lined up, although he's likely to be in high demand.

"I will be resigning from Baidu, where I have been leading the company's AI Group," wrote Ng in the Medium blog post.

"After Baidu, I am excited to continue working toward the AI transformation of our society and the use of AI to make life better for everyone."

Along with the likes of DeepMind, Google, Microsoft and Facebook, Baidu is often seen as one of the world leaders when it comes to AI research. The company's CEO Robin Li described AI as Baidu's "key strategic focus for the next decate" and Baidu managed to poach Microsoft exec Qi Lu from Satya Nadella.

As one of the highest-regarded minds in the industry, Ng is likely a big loss for Baidu and stock in the company fell 2.7%, or roughly $1.5 billion after Ng announced his exit.

There is currently a war for AI talent taking place around the world, with tech giants willing to pay hundreds of thousands of dollars for people who can help them shape their next generation of products. AI is being embedded into an increasing range of products, from Siri in the Apple iPhone to the navigation systems being integrated in Uber's self driving cars.

Prior to joining Baidu in May 2014, Ng founded and led Google Brain, which develops massive-scale deep learning algorithms for the search giant. Among other things, Google Brain developed a massive neural network that learned from unlabelled YouTube videos to detect cats.

Here is Andrew Ng's full blog post.

Opening a new chapter of my work in AI

Dear Friends,

I will be resigning from Baidu, where I have been leading the company's AI Group. Baidu's AI is incredibly strong, and the team is stacked up and down with talent; I am confident AI at Baidu will continue to flourish. After Baidu, I am excited to continue working toward the AI transformation of our society and the use of AI to make life better for everyone.

Artificial Intelligence at Baidu

I joined Baidu in 2014 to work on AI. Since then, Baidu's AI group has grown to roughly 1,300 people, which includes the 300-person Baidu Research. Our AI software is used every day by hundreds of millions of people. We have had tremendous revenue and product impact, through the many dozens of AI projects that support our existing businesses in search, advertising, maps, take-out delivery, voice search, security, consumer finance and many more.

We have also used AI to develop new lines of business. My team birthed one new business unit per year each of the last two years: autonomous driving and the DuerOS Conversational Computing platform. We are also incubating additional promising technologies, such as face-recognition (used in turnstiles that open automatically when an authorized person approaches), Melody (an AI-powered conversational bot for healthcare) and several more. As the principal architect of Baidu's AI strategy, I am proud to have led the incredible rise of AI within the company.

Baidu is now one of the few companies with world-class expertise in every major AI area: speech, NLP, computer vision, machine learning, knowledge graph. It's been an honor to lead the AI Group and work with Baidu's remarkable team, from the executive leadership to the brilliant engineers, scientists, product managers and others. Robin Li was the first large company CEO to clearly see the value of deep learning, and remains globally one of the best AI CEOs. COO Lu Qi is a seasoned business executive with significant experience in AI; with his leadership, AI at Baidu will flourish. Wang Haifeng, the new head of the AI Group, is a fantastic researcher and technology leader; his leadership firmly positions the team for future greatness. Lin Yuanqing, our newly appointed head of Baidu Research, is a brilliant technology and business leader, who is creating both great AI technologies and great business results. Under their capable leadership, and that of other AI stars at Baidu such as Adam Coates, Jing Kun, Li Ping, Xu Wei, and Zhu Kaihua, AI at Baidu will continue to thrive, and I will be cheering their progress.

I've also been privileged to learn from both the U.S. and Chinese AI communities — both of which are powerhouses. The U.S. is very good at inventing new technology ideas. China is very good at inventing and quickly shipping AI products. I'm happy also to have had an opportunity to contribute to the rise of AI in both China and the U.S.

AI is the new electricity

Just as electricity transformed many industries roughly 100 years ago, AI will also now change nearly every major industry — healthcare, transportation, entertainment, manufacturing — enriching the lives of countless people. I am more excited than ever about where AI can take us.

As the founding lead of the Google Brain project, and more recently through my role at Baidu, I have played a role in the transformation of two leading technology companies into "AI companies." But AI's potential is far bigger than its impact on technology companies.

I will continue my work to shepherd in this important societal change. In addition to transforming large companies to use AI, there are also rich opportunities for entrepreneurship as well as further AI research. I want all of us to have self-driving cars; conversational computers that we can talk to naturally; and healthcare robots that understand what ails us. The industrial revolution freed humanity from much repetitive physical drudgery; I now want AI to free humanity from repetitive mental drudgery, such as driving in traffic. This work cannot be done by any single company — it will be done by the global AI community of researchers and engineers. My Machine Learning MOOC on Coursera helped many people enter AI. In addition to working on AI myself, I will also explore new ways to support all of you in the global AI community, so that we can all work together to bring this AI-powered society to fruition.

I am more optimistic than ever about the fantastic future we will build with AI. Lets keep working hard to get AI to help everyone!
