How Can You Tell If Your Recommender System Is Any Good?


It's an exciting time to be working on recommender systems. Not only are they more relevant than ever before, with Facebook recently investing in a 12 trillion parameter model and Amazon estimating that 35% of their purchases come from recommendations, but there is a wealth of powerful, cutting edge techniques with code available for anyone to try. So the tools are at hand to build something neat to deliver personalized recommendations to your users! The problem is, knowing if it's any good. When John Harrison was developing the marine chronometer, which revolutionized long-distance sea travel by allowing ships to accurately determine their longitude, he had a problem with evaluation: to measure the device's accuracy in practice required a long sea voyage. Similarly, the gold standard for evaluating a recommender system is expensive and time consuming: an A/B test, in which real users selected at random see the new model, and their behavior is compared to users who saw the old model. In both cases if this was the only way to evaluate, it would be impossible to try out new ideas with agility, or to quickly iron out flaws. Instead, it's necessary to have a quick, cheap way to evaluate a model.

AI in Real Estate: Top 10 Real Estate AI Apps for Investors


Global pandemic limitations have had a direct influence on traditional real estate processes – and for the better, unexpectedly. Thousands of businesses, realtors, appraisers, mortgage lenders, and others have been forced to manage the crisis by incorporating rapidly emerging PropTech, and with good cause. Real estate AI apps can manage predetermined data flows, learn user behavior, streamline and speed operations, and allow more accurate assessments and market forecasts in the short term. Real estate AI apps are being embraced by homeowners, potential renters, and purchasers, and investors are aware that real estate is the world's greatest asset class. These top 10 AI apps help real estate professionals interact with prospects more rapidly, boost sales, manage renters and properties, and more.

HomePod mini update lets it become your default Apple TV speaker


Apple didn't even touch on the HomePod line during its iPhone 13 event, but that doesn't mean the smart speakers will go untouched this fall. To start, you can set two or more HomePod minis as your default speakers for an Apple TV 4K. You won't have to specify them when it's time to sit down for a movie. They won't exactly produce thunderous audio, but they could save you from buying separate smart speakers or a pricier soundbar. The update enables Siri voice control through supporting HomeKit accessories.

On Solving a Stochastic Shortest-Path Markov Decision Process as Probabilistic Inference


We propose solving the general Stochastic Shortest-Path Markov Decision Process (SSP MDP) as probabilistic inference. Furthermore, we discuss online and offline methods for planning under uncertainty. In an SSP MDP, the horizon is indefinite and unknown a priori. SSP MDPs generalize finite and infinite horizon MDPs and are widely used in the artificial intelligence community. Additionally, we highlight some of the differences between solving an MDP using dynamic programming approaches widely used in the artificial intelligence community and approaches used in the active inference community.

AI Everywhere


From data centers, through edge accelerators to endpoint devices: Artificial intelligence (AI) Applications range from large scale analysis of medical data and online retail recommendation engines, to robotics and computer vision, to sensor fusion in the tiniest sensor nodes. The infusion of AI techniques into so many areas of computing is changing compute paradigms across the board. Our Virtual Event will provide answers to questions like: How to keep up with these changes, especially given AI's propensity to evolve at a staggering rate? How does one design chips or systems for a constantly shifting workload like this? How does one make the call between maximising performance today and keeping some flexibility for the sake of future-proofing? AI in the Data Center AI in the data center is revolutionising online retail in the cloud and applications like medical imaging and the financial sector at the enterprise level.

9 Essential Data Scientist Skills 2021


Everyone wants to gain the best skills for the data scientist job description now that data science is sweeping over the business world. Every day, 2.5 quintillion bytes of data are produced, and businesses want experts who can turn this data into insights and benefit from it. As organizations face difficulties that may only be handled via effective data analysis, data scientists are in high demand. Data science has undeniably become a critical component of organizations, allowing them to make well-informed judgements based on statistical data, trends, and figures. You must acquire the abilities necessary for data scientist roles in various firms and organizations to become an expert in the field.

Cross-Market Product Recommendation


We study the problem of recommending relevant products to users in relatively resource-scarce markets by leveraging data from similar, richer in resource auxiliary markets. We hypothesize that data from one market can be used to improve performance in another. Only a few studies have been conducted in this area, partly due to the lack of publicly available experimental data. To this end, we collect and release XMarket, a large dataset covering 18 local markets on 16 different product categories, featuring 52.5 million user-item interactions. We introduce and formalize the problem of cross-market product recommendation, i.e., market adaptation.

5 Applications of Artificial Intelligence In Different Business Areas


Artificial intelligence (AI) helps improve predictive analytics, sales forecasting, customer needs, process automation and security systems. The concept of artificial intelligence or machines that aim to emulate human thinking is undergoing vigorous research and is a topic that is increasingly being associated with the Internet of things. An AI enabled IoT system extends the functionality and value of an organization's offering, without the need for committing additional resources to achieve the increased value. This is exemplified by under Armour(UA) and IBM's collaboration on the UA Record app, which is an AI-based personal fitness coaching system, that uses a variety of sensor data to suggest highly personalized, context-relevant fitness activities to users. Such applications of AI are going to be more commonplace in the future as they are already having a significant impact on many industries.

AI-powered ecommerce recommendation engine Constructor nabs $55M


The Transform Technology Summits start October 13th with Low-Code/No Code: Enabling Enterprise Agility. Constructor, a San Francisco, California-based ecommerce personalization startup, today announced that it raised $55 million in a series A round led by Silversmith Capital Partners. The funding, which brings the company's total raised to $61.5 million, will be put toward product development, hiring, and go-to-market efforts, according to CEO Eli Finkelshteyn. Online commerce conversions are well behind in-store -- the average online shop sees less than 3% in conversions. But even though $4.2 trillion was spent on ecommerce platforms in 2020 alone, few ecommerce retailers have invested in a digital merchandising strategy.

Machine Learning


Machine Learning (ML) is NOT the same as Artificial Intelligence. That said, the connection between the two is undoubtedly undeniable. Machine learning is part of AI in which the algorithms allow the system to locate patterns and learn the trends in the data and try to make decisions without human intervention. ML technology is evolving so rapidly that every generation is entirely different from the last. The first types of ML were just programmed to perform certain tasks in case of a specific event.
