Word embeddings are a powerful approach for unsupervised analysis of language. Recently, Rudolph et al. (2016) developed exponential family embeddings, which cast word embeddings in a probabilistic framework. Here, we develop dynamic embeddings, building on exponential family embeddings to capture how the meanings of words change over time. We use dynamic embeddings to analyze three large collections of historical texts: the U.S. Senate speeches from 1858 to 2009, the history of computer science ACM abstracts from 1951 to 2014, and machine learning papers on the Arxiv from 2007 to 2015. We find dynamic embeddings provide better fits than classical embeddings and capture interesting patterns about how language changes.

Baidu shares fell on Wednesday, after chief scientist Andrew Ng announced he is leaving the company less than three years after joining. Ng announced his departure in a post on Medium late Tuesday. Baidu shares were down more than 1½ percent in market hours, trading around 168.51. Ng had joined the company in 2014 to help help develop new businesses around artificial intelligence and machine learning, areas Baidu has previously identified as a major strategic focus. Baidu told the Financial Times it will not hire a direct replacement, but instead move Ng's teams into the AI Group, which will be headed by current vice president Haifeng Wang.

The world population is expected to reach 9.7 billion by 2050. China and India, the two largest countries in the world, have populations totaling around one billion. In four years, by 2022, India is predicted to have the largest population in the world, surpassing China. This means we need new ways to grow food that are smarter and helps regulate our use of land, water and energy in order to feed the planet and avoid a global food crisis.

Robots have helped increase revenue for numerous firms and a new survey has revealed that people feel the machines could do the same for the wealth of a nation. Approximately one in four UK citizens believe robots would make better decisions than elected human officials when it comes to boosting the economy. The research also uncovered that 66 percent of people foresee AI powered machines working in government positions by 2037. Approximately one in four UK citizens believe robots would make better decisions than human officials when it comes to boosting the economy. A robot run world is a fear among many people across the globe, as some worry about the future of their jobs. But according to a survey conducted by OpenText, a firm that provides management solutions, people living in the UK believe it could revolutionize their country.

It's March of the Machines this week, so we had a look at some surprising companies hiring in emerging technologies such as IoT, AI and machine learning. It has never been a more exciting time to work in artificial intelligence (AI) or the internet of things (IoT). There are so many career options available to those who want to pursue these emerging technologies, and successful candidates can make a real difference in how society uses technology. But, while you might know that you want to work in AI or machine learning, you might be left wondering where exactly to start your job search. What companies are hiring in that sector?

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.

What you see and experienced so far is just the beginning of what is forecast to be a billion-dollar industry in less than 10 years. Many top brands, including Uber, Sephora, and CNN, have already adopted chatbots. Here are 11 amazing facts you might not know about chatbots. The top four messaging apps are bigger than the top four social networks, according to BI Intelligence. More than 1.4 billion people used messaging apps in 2016, according to eMarketer. By 2019, more than 25 percent of the world's population (roughly 1.75 billion people) will be using mobile messaging apps.

China has now overtaken Japan for having more robots than anywhere else in the world. The Chinese government is concerned about an ageing population and the rising cost of human labour making Chinese products less competitive. It is giving over $100 Billion in subsidies for companies to replace more human workers with robots. It's hoped that the workers that will no longer work in the factories will move to the growing service sector, in part to help look after the ageing population. Countries In the west have already lost large numbers of manufacturing jobs to china but we shouldn't get too smug about our white-collar jobs in high tech, administration, clerical and production being safe from A.I. systems in the future.

Legal research company Casetext has raised $12 million in a new round of funding. The money will be used to expand its software platform that offers insights into cases cited in legal documents and further develop CARA (Case Analysis Research Assistant), an AI-powered assistant for lawyers. Using natural language understanding, Casetext scans the text of legal briefs to locate and analyze case citations. The company also offers access to 10 million court cases and statutes annotated by a community of litigators. The $12 million funding round was led by Canvas Ventures, with participation from Union Square Ventures, 8VC, and Red Sea Ventures.

"It is because of them that my little boy smiles again," a mum's heartfelt thanks to the owners of a dog with skin condition vitiligo, and the Singaporean creator of a selective dating app comes to its defence. Two young kids with a long-term skin condition are making headlines after meeting a dog sharing the same rare autoimmune disease. Eight-year old Carter, from Arkansas, developed vitiligo in 2014, a condition characterised by areas of the skin losing their pigmentation. Ava, who is 10 and from Canada, also has vitiligo which she developed when she was four. But Carter and Ava have more than just that in common.
