The evolution of the retail business presents new challenges and raises pivotal questions on how to reinvent stores and supply chains to meet the growing demand of the online channel. One of the recent measures adopted by omnichannel retailers is to address the growth of online sales using in-store picking, which allows serving online orders using existing assets. However, it comes with the downside of harming the offline customer experience. To achieve picking policies adapted to the dynamic customer flows of a retail store, we formalize a new problem called Dynamic In-store Picker Routing Problem (diPRP). In this relevant problem - diPRP - a picker tries to pick online orders while minimizing customer encounters. We model the problem as a Markov Decision Process (MDP) and solve it using a hybrid solution approach comprising mathematical programming and reinforcement learning components. Computational experiments on synthetic instances suggest that the algorithm converges to efficient policies. Furthermore, we apply our approach in the context of a large European retailer to assess the results of the proposed policies regarding the number of orders picked and customers encountered. Our work suggests that retailers should be able to scale the in-store picking of online orders without jeopardizing the experience of offline customers. The policies learned using the proposed solution approach reduced the number of customer encounters by more than 50% when compared to policies solely focused on picking orders. Thus, to pursue omnichannel strategies that adequately trade-off operational efficiency and customer experience, retailers cannot rely on actual simplistic picking strategies, such as choosing the shortest possible route.

A multi-armed bandit (MAB) is a machine learning framework that uses complex algorithms to dynamically allocate resources when presented with multiple choices. In other words, it's an advanced form of A/B testing that's most commonly used by data analysts, medicine researchers, and marketing specialists. Before we delve deeper into the concept of multi-armed bandits, we need to discuss reinforcement learning, as well as the exploration vs. exploitation dilemma. Then, we can focus on various bandit solutions and practical applications. Alongside supervised and unsupervised learning, reinforcement learning is one of the basic three paradigms of machine learning. Unlike the first two archetypes we mentioned, reinforcement learning focuses on rewards and punishments for the agent whenever it interacts with the environment.

Product ranking is the core problem for revenue-maximizing online retailers. To design proper product ranking algorithms, various consumer choice models are proposed to characterize the consumers' behaviors when they are provided with a list of products. However, existing works assume that each consumer purchases at most one product or will keep viewing the product list after purchasing a product, which does not agree with the common practice in real scenarios. In this paper, we assume that each consumer can purchase multiple products at will. To model consumers' willingness to view and purchase, we set a random attention span and purchase budget, which determines the maximal amount of products that he/she views and purchases, respectively. Under this setting, we first design an optimal ranking policy when the online retailer can precisely model consumers' behaviors. Based on the policy, we further develop the Multiple-Purchase-with-Budget UCB (MPB-UCB) algorithms with $\~O(\sqrt{T})$ regret that estimate consumers' behaviors and maximize revenue simultaneously in online settings. Experiments on both synthetic and semi-synthetic datasets prove the effectiveness of the proposed algorithms.

The purpose of this book is to teach you modern linear algebra. But this is not about memorizing some key equations and slugging through abstract proofs; the purpose is to teach you how to think about matrices, vectors, and operations acting upon them. You will develop a geometric intuition for why linear algebra is the way it is. And you will understand how to implement linear algebra concepts in Python code, with a focus on applications in machine learning and data science. Many traditional linear algebra textbooks avoid numerical examples in the interest of generalizations, expect you to derive difficult proofs on your own, and teach myriad concepts that have little or no relevance to application or implementation in computers.

FedEx employees are working around the clock to make sure packages get to people in time for Christmas. For the first time ever, some Walmart customers in Florida, Texas and Arizona will be able to have their packages delivered by drone. Walmart's drone service officially launched for select customers in Tampa and Orlando, Florida; Phoenix and the Dallas-area just ahead of the holidays. The nation's largest retailer has been working with national drone services provider DroneUp since 2020 when it began trialing deliveries of at-home COVID-19 self-collection kits. Walmart announced in May 2022 that it was expanding its DroneUp delivery network to reach 4 million U.S. households across six states including Arizona, Arkansas, Florida, Texas, Utah and Virginia by the end of the year.

Congratulations, you made it through another rough year. We've traditionally reserved the end of the year as an opportunity to have a little fun while shining a light on the year's biggest failings in tech, with a roundup affectionately known as CNET's annual Tech Turkeys. In the past, the ribbing was good natured, pointing out silly products or a random faux pas at a conference (hello, Michael Bay!). Then the problems across Big Tech piled on. Congressional hearings, election-swinging misinformation and privacy-invading breaches became a regular thing.
