Working with Stochastic Programming part1(Advanced Statistics)


Abstract: his paper features expectiles in dynamic and stochastic optimization. Expectiles are a family of risk functionals characterized as minimizers of optimization problems. For this reason, they enjoy various unique stability properties, which can be exploited in risk averse management, in stochastic optimization and in optimal control. The paper provides tight relates of expectiles to other risk functionals and addresses their properties in regression. Further, we extend expectiles to a dynamic framework.

Google reshuffles virtual assistant unit with focus on Bard A.I. technology


Google is reshuffling the reporting structure of its virtual assistant unit -- called Assistant -- to focus more on Bard, the company's new artificial intelligence chat technology. In a memo to employees on Wednesday, titled "Changes to Assistant and Bard teams," Sissie Hsiao, vice president and lead of Google Assistant's business unit, announced changes to the organization that show the unit heavily prioritizing Bard. Jianchang "JC" Mao, who reported directly to Hsiao, will be leaving the company for personal reasons, according to the memo, which was viewed by CNBC. Mao held the position of vice president of engineering for Google Assistant and "helped shape the Assistant we have today," Hsiao wrote. Taking Mao's place will be 16-year Google veteran Peeyush Ranjan, who most recently held the title of vice president in Google's commerce organization, overseeing payments.

Online daters are less open-minded than their filters suggest


One of the biggest differences between online dating and the old-fashioned sort is the size of the pool. The number of people using dating apps dwarfs offline social networks. So sites offer filters that let users exclude unwanted groups. Your browser does not support the audio element. The diversity of tastes among giant user bases should make apps a haven for people who struggle with dating offline.

Network Optimization With a Cognitive Time Series Forecasting Solution


Telecommunication companies are generating billions of dollars in revenue annually by leveraging the power of Artificial Intelligence, Data Science, and IoT integrations. In 2020, a potential American telecom company/operator, AT&T, generated €161.5 billion in revenue, but there is a decline in annual revenues compared to 2021 and 2022. The reason behind the revenue decline can be the abandonment of Artificial intelligence technologies. So, what should these companies have to do? To achieve success over the competitors and increase revenue streams in 2023.

State of Recommender Systems in 2023 part1(Machine Learning)


Abstract: As the last few years have seen an increase in online hostility and polarization both, we need to move beyond the fack-checking reflex or the praise for better moderation on social networking sites (SNS) and investigate their impact on social structures and social cohesion. In particular, the role of recommender systems deployed at large scale by digital platforms such as Facebook or Twitter has been overlooked. This paper draws on the literature on cognitive science, digital media, and opinion dynamics to propose a faithful replica of the entanglement between recommender systems, opinion dynamics and users' cognitive biais on SNSs like Twitter that is calibrated over a large scale longitudinal database of tweets from political activists. This model makes it possible to compare the consequences of various recommendation algorithms on the social fabric and to quantify their interaction with some major cognitive bias. In particular, we demonstrate that the recommender systems that seek to solely maximize users' engagement necessarily lead to an overexposure of users to negative content (up to 300\% for some of them), a phenomenon called algorithmic negativity bias, to a polarization of the opinion landscape, and to a concentration of social power in the hands of the most toxic users.

State of Recommender Systems in 2023 part4(Machine Learning)


Abstract: Recommendation models that utilize unique identities (IDs) to represent distinct users and items have been state-of-the-art (SOTA) and dominated the recommender systems (RS) literature for over a decade. Meanwhile, the pre-trained modality encoders, such as BERT and ViT, have become increasingly powerful in modeling the raw modality features of an item, such as text and images. Given this, a natural question arises: can a purely modality-based recommendation model (MoRec) outperforms or matches a pure ID-based model (IDRec) by replacing the itemID embedding with a SOTA modality encoder? In fact, this question was answered ten years ago when IDRec beats MoRec by a strong margin in both recommendation accuracy and efficiency. We aim to revisit this old' question and systematically study MoRec from several aspects.

Zoom announces AI features that act as your personal assistant


Zoom is jumping on the AI bandwagon with new features that help you stay on top of meetings. On Monday, the video conferencing company announced(Opens in a new tab) additions to its AI-powered tool Zoom IQ.
