Each organization of competitions and benchmarks involves a large number of practical problems, such as obtaining sufficient financial support or recruiting participants through appropriate incentives and community engagement. In addition to defining scientific tasks, preparing data and creating challenges, a very important practical administrative organization remains to be achieved. Indeed, cost assessment, corresponding requests for financial support and adequate publicity are key factors for successful organization of the competition. In addition, a good understanding of the incentives that lead participants to engage in a given challenge is fundamental for effective practical organization success. In this chapter, we will cover these topics and give some practical tips and examples for overcoming the "challenge" of organizing the challenges. How to incentivize participants to work on complex problems is a key feature of challenge organization. In this section, we review various types of motivations (Figure 1.1), from a participant perspective, and give practical tips to optimize those incentives.

This paper examines whether temporal difference methods for training connectionist networks, such as Suttons's TO(') algorithm, can be suc(cid:173) cessfully applied to complex real-world problems. A number of important practical issues are identified and discussed from a general theoretical per(cid:173) spective. These practical issues are then examined in the context of a case study in which TO(') is applied to learning the game of backgammon from the outcome of self-play. This is apparently the first application of this algorithm to a complex nontrivial task. It is found that, with zero knowledge built in, the network is able to learn from scratch to play the entire game at a fairly strong intermediate level of performance, which is clearly better than conventional commercial programs, and which in fact surpasses comparable networks trained on a massive human expert data set.

The hit TV anthology'Black Mirror' has captivated viewers with speculative tales of how emerging technologies like artificial intelligence, machine learning and intelligent automation could go horribly awry. It makes for great television, but do similar futures await learning leaders who are looking to strategically leverage these technologies? We have seen where AI-powered digital technologies are steadily and increasingly becoming part of our daily lives. Amazon's Alexa, Apple's Siri, Google's Assistant and Microsoft's Cortana are accessible in many of our homes and through our digital devices. These and other AI agents are evolving and becoming more capable of completing processes humans are traditionally tasked with.

Businesses today are dealing with huge amounts of data and it's arriving faster than ever before. At the same time, the competitive landscape is changing rapidly and it's critical to be able to make decisions fast. As Jason Jennings and Laurence Haughton put it "It's not the big that eat the small… It's the fast that eat the slow". Business success comes from making fast decisions using the best possible information. Machine learning (ML) is powering that evolution.

The right planning and application of machine learning can help businesses grow, compete and prepare for the future.

Predictive algorithms promoted and used by Hackney council to identify those most in need of scarce preventive services is an important issue for us to think more deeply about. In that article, Steve Liddicott reasoned that in the context of reduced spending on prevention services, identifying those most in need earlier could prevent children ending up in more intensive services like child protection. The article presents the reduction of spending as a given and promotes algorithms as a method of distributing what little is left. In this response, we argue this is not a benign activity and is ethically fraught. Firstly, the reduction of services leaves significant holes that an algorithm can't fix.

More and more companies are building and applying deep learning models in their business. Several practical issues should be taken into consideration before these models are put into production. Consider this scenario: you may build a model that works perfectly with training and validation data, but it doesn't perform well after deploying the model in real scenarios. Or, you may struggle with getting better performance compared to traditional machine learning models. While the latter case will make you rethink whether to invest more resourcing on this, the former situation is more risky and you may not realize it until you put your models into production.
