Nowadays, recommender systems already impact almost every facet of peoples lives. To provide personalized high quality recommendation results, conventional systems usually train pointwise rankers to predict the absolute value of objectives and leverage a distinct shallow tower to estimate and alleviate the impact of position bias. However, with such a training paradigm, the optimization target differs a lot from the ranking metrics valuing the relative order of top ranked items rather than the prediction precision of each item. Moreover, as the existing system tends to recommend more relevant items at higher positions, it is difficult for the shallow tower based methods to precisely attribute the user feedback to the impact of position or relevance. Therefore, there exists an exciting opportunity for us to get enhanced performance if we manage to solve the aforementioned issues. Unbiased learning to rank algorithms, which are verified to model the relative relevance accurately based on noisy feedback, are appealing candidates and have already been applied in many applications with single categorical labels, such as user click signals. Nevertheless, the existing unbiased LTR methods cannot properly handle multiple feedback incorporating both categorical and continuous labels. Accordingly, we design a novel unbiased LTR algorithm to tackle the challenges, which innovatively models position bias in the pairwise fashion and introduces the pairwise trust bias to separate the position bias, trust bias, and user relevance explicitly. Experiment results on public benchmark datasets and internal live traffic show the superior results of the proposed method for both categorical and continuous labels.

Machine learning and artificial intelligence are often used interchangeably, but they are two very different things. Artificial Intelligence (AI) is a broad field that has been around for decades -- it's the technology behind Siri and Alexa. Machine Learning (ML), on the other hand, is a subset of AI that uses statistical techniques to allow computers to learn without being explicitly programmed with rules or instructions. Therefore, you can see that machine learning and artificial intelligence aren't interchangeable terms; rather they're related fields in computer science that both utilize mathematics and statistics to create intelligent behavior from machines. To better understand the difference between the two, think of it this way: AI is a toaster that can make toast; ML is an algorithm where you tell the toaster how dark you want your toast and when.

A person with a disability is defined as a person having an impairment which can be physical, sensory or mental in nature. According to the United Nations as of the year 2021 the world population stands at a whopping 7.9 billion. Out of 7.9 billion people more than 1 billion people have some form of disability which is approximately 15 percent of the total population of the world. Life is hard enough as it is but for people with disabilities there are additional hardships that they have to face every single day. These hardships vary according to the type of disability.

Organizations are turning to conversational AI to meet communication demands, with the adoption of chatbots and conversational interfaces reaching an unprecedented scale. Yes, it's time to get comfortable speaking with machines. Conversation – whether it's with customers, or between employees – is a very informal process, but thanks to AI, we may be able to better capture the essence of these discussions. That's the word from a report out of Accenture, which notes that conversation is "also a complex construct. Even the simplest interaction has layers of richness and nuance--it takes effort and understanding to get conversation right."

Artificial Intelligence (AI), a revolutionize technique with the help of which, it is possible to create intelligent machines which can behave, think, and even make decisions just like a human. In short, it is concerned with the design of intelligence in artificial, particularly a computer, a computer-aided robot, or software which think intelligently. A Leap in the essence of the Artificial Intelligence lead to the formation of accelerated world-changing technologies that can work in the domain to impact the future of all the entities around, preferably for the upgradation of humanity. AI is a dynamic tool, efficient in multitasking used across industries for better decision making, optimizing efficiency and getting rid of repetitive work. In today's world, Artificial Intelligence plays an undeniable important part in the real world including different areas such as automobile, agriculture, social media, Entertainment, Gaming, Education, Surveillance, Finance, Robotics, Space Exploration, Healthcare etc. AI proved to be a breakthrough in Health sector for differently-abled people by making it easier to create interactive tools that support physical accessibility and independence.

Black Friday typically presents lots of opportunities to smarten up your abode, with everything from connected bulbs to robot vacuums undergoing deep discounts for the holidays. We've already seen a few of these items go on sale as part of early Black Friday efforts, and we'll definitely see more today and over the weekend. These devices include not just the aforementioned bulbs and robot vacuums but also sous vide machines, Instant Pots, Nest Hubs and more. To prevent you from sifting through all these sales yourself, we've done the hard work for you. Here are some of the best ones we've seen so far. One of our favorite robot vacuums, the iRobot Roomba 694, is now $95 off, which brings its price down to $180.

It's officially Black Friday and that means if you didn't snatch up any of the early deals that came and went earlier this month, now's the time to shop. Despite kicking off the holiday season (unbearably) early this year with a deluge of deals, retailers are still have some compelling Black Friday sales today. However, just like most years, not every deal is worth your money -- especially when it comes to gadgets and electronics. We've sifted through all of the Black Friday tech deals we could find to come up with a list of only the best ones that you should consider this year. Here are the best tech deals we could find for Black Friday.

According to a recent study from market research firm Graphical Research, the global artificial intelligence in retail market size is set to register a significant growth during the forecast time frame. The public and private sector investments in advanced technologies like AI are rising at a robust rate. Investors have realized the power of AI and its anticipated deployment in myriad use-cases, thereby boosting the adoption of AI in retail stores. Recommendation engine solutions held more than 25% share of the North America artificial intelligence (AI) in retail market in 2020. High-end technologies, such as AI, machine learning, and data analytics are being heavily implemented across the retail sector.
