Online Repositioning in Bike Sharing Systems

AAAI Conferences

Due to increased traffic congestion and carbon emissions, Bike Sharing Systems (BSSs) are adopted in various cities for short distance travels, specifically for last mile transportation. The success of a bike sharing system depends on its ability to have bikes available at the "right" base stations at the "right" times. Typically, carrier vehicles are used to perform repositioning of bikes between stations so as to satisfy customer requests. Owing to the uncertainty in customer demand and day-long repositioning, the problem of having bikes available at the right base stations at the right times is a challenging one. In this paper, we propose a multi-stage stochastic formulation, to consider expected future demand over a set of scenarios to find an efficient repositioning strategy for bike sharing systems. Furthermore, we provide a Lagrangian decomposition approach (that decouples the global problem into routing and repositioning slaves and employs a novel DP approach to efficiently solve routing slave) and a greedy online anticipatory heuristic to solve large scale problems effectively and efficiently. Finally, in our experimental results, we demonstrate significant reduction in lost demand provided by our techniques on real world datasets from two bike sharing companies in comparison to existing benchmark approaches.


Apple Silicon and Machine Learning – Monday Note

#artificialintelligence

When Apple introduced its 64-bit A7 processor in September, 2013, they caught the industry by surprise. According to an ex-Intel gent who's now at a long-established Sand Hill Road venture firm, the competitive analysis group at the imperial x86 maker had no idea Apple was cooking a 64-bit chip. As I recounted in a September 2013 Monday Note titled 64 bits. And We'll Have It In 6 Months, competitors and Intel stenographers initially dismissed the new chip. They were in for a shock: Not only did the company jump to the head of the race for powerful mobile chips, but Apple also used its combined control of hardware and software to build what Warren Buffett refers to as a wide "wide moat": The industry came to accept the idea Apple has one of the best, if not the best, silicon design team; the company just hired Esin Terzioglu, who oversaw the engineering organization of Qualcomm's core communications chips business.


Finally! Google sells Boston Dynamics to SoftBank

Robohub

In a long-awaited transaction, The New York Times Dealbook announced that SoftBank was buying Boston Dynamics from Alphabet (Google). Also included in the deal is the Japanese startup Schaft. Acquisition details were not disclosed. Both Boston Dynamics and Schaft were acquired by Google when Andy Rubin was developing Google's robot group through a series of acquisitions. Both companies have continued to develop innovative mobile robots.


SoftBank Buys Robotics Leader Boston Dynamics From Alphabet

"Smart robotics are going to be a key driver of the next stage of the Information Revolution," he said. "I am thrilled to welcome them to the SoftBank family and look forward to supporting them as they continue to advance the field of robotics and explore applications that can help make life easier, safer and more fulfilling," Son said of Boston Dynamics.


Softbank buys Boston Dynamics (and its robots) from Google

Engadget

It's been over a year since we heard that Google's parent company Alphabet wanted to sell its robotics company Boston Dynamics, and now it has a buyer: Softbank. The Japanese company has been working on its own robots for years, including the helpful Pepper, and now they'll be under the same umbrella as Handle, Big Dog, Atlas, WildCat and all the rest. Google acquired the MIT spin-off in 2013, when Andy Rubin was still still leading its robotics efforts instead of building his own phone. Along with Japan's SCHAFT (which dominated the 2013 DARPA challenge and is also being acquired by Softbank), it became a part of the reorganized X division under Alphabet, but clearly fell out of the company's long-term plans. The terms of the deal have not been revealed, however Softbank CEO Masayoshi Son said in a statement that "Smart robotics are going to be a key driver of the next stage of the Information Revolution, and Marc and his team at Boston Dynamics are the clear technology leaders in advanced dynamic robots. I am thrilled to welcome them to the SoftBank family and look forward to supporting them as they continue to advance the field of robotics and explore applications that can help make life easier, safer and more fulfilling."


If Your Company Isn't Good at Analytics, It's Not Ready for AI

#artificialintelligence

Management teams often assume they can leapfrog best practices for basic data analytics by going directly to adopting artificial intelligence and other advanced technologies. But companies that rush into sophisticated artificial intelligence before reaching a critical mass of automated processes and structured analytics can end up paralyzed. They can become saddled with expensive start-up partnerships, impenetrable black-box systems, cumbersome cloud computational clusters, and open-source toolkits without programmers to write code for them. By contrast, companies with strong basic analytics -- such as sales data and market trends -- make breakthroughs in complex and critical areas after layering in artificial intelligence. For example, one telecommunications company we worked with can now predict with 75 times more accuracy whether its customers are about to bolt using machine learning.


How AI is disrupting major industries

#artificialintelligence

Advances in artificial intelligence tend to provoke polarizing reactions for most people. Or two, a utopian futurist society where humans are freed from mundane labor and complex challenges are solved by machines. Wherever you fall on the AI anxiety spectrum, the fundamental truth is that we are entering a major transformative cycle across nearly every industry. While AI is currently dominated by increased media attention and business hype, the way consumers and brands interact is quietly poised to make a tectonic shift over the next two years through marketing solutions built with AI in their core DNA. In a recent Wakefield/Demandbase study, 80 percent of marketing leaders say that AI will "revolutionize" marketing by 2020.


Artificial intelligence could help telcos catch up on customer experience - VanillaPlus - The global voice of Telecoms IT

#artificialintelligence

Ask anyone on the street about their last great customer experience. Odds are, their story won't involve a mobile service provider. In fact, says Comptel's Niilo Fredrikson, in 2016 all four major U.S. telecom companies held a spot in a list of the worst 15 companies in America ranked by poor customer service. The average Net Promoter Score for the telecommunications industry routinely ranks among the lowest of any industry, and that factors in telcos from every corner of the globe. Operators simply have a reputation for offering poor customer experiences.


Data with Relationships Yields Insights Before Analytics

#artificialintelligence

Data's utility is not rooted in amassing the largest quantities of data; it's predicated on understanding how data relates–both to itself and to business objectives–in a timeframe that fits the speed of business. Relationships between data can be formed by linking data based on meaningful statements within a Semantic Graph or triplestore database. These relationships provide a form of machine intelligence that is essential to expanding the understanding of how data relates to each other. Based on these data relationships, the reasoning in the triplestores will instantly conclude that Patient X is at risk of a drug interaction. Such an example illustrates the instantaneous usefulness of relationships between data.


Does artificial intelligence save communications? Could you write PPT for me?

When Ke Jie three negative AlphaGo, a friend joked, "your communications industry, if you are still familiar with OTT, ignoring artificial intelligence, it is estimated that no longer be able to turn the body.". You see, Google I\/O conference announced last year, from Mobile First to AI First strategic transformation. We are still fighting in the mobile Internet, people have entered the era of artificial intelligence. However, the pioneers of the telecommunications industry have begun to layout artificial intelligence. From Google, Facebook, Amazon, and then to Microsoft, the world's most Pinnacle Technology Corp are turning to artificial intelligence.
