Nowadays, recommender systems and search engines play an integral role in fashion e-commerce. Still, many challenges lie ahead, and this study tries to tackle some. This article first suggests a content-based fashion recommender system that uses a parallel neural network to take a single fashion item shop image as input and make in-shop recommendations by listing similar items available in the store. Next, the same structure is enhanced to personalize the results based on user preferences. This work then introduces a background augmentation technique that makes the system more robust to out-of-domain queries, enabling it to make street-to-shop recommendations using only a training set of catalog shop images. Moreover, the last contribution of this paper is a new evaluation metric for recommendation tasks called objective-guided human score. This method is an entirely customizable framework that produces interpretable, comparable scores from subjective evaluations of human scorers.

Amazon's Alexa voice assistant will soon tell users when items they've had an eye on are about to be on sale. The company announced on Thursday that Alexa will notify Prime customers up to 24 hours in advance of upcoming sales on items in their Amazon wish list and shopping cart, or items that were marked "saved for later" on the platform. The feature will work with fourth-generation Echo smart speakers and newer. For example, if a customer is looking at a new TV and it's been sitting in a wish list, Alexa will give the consumer a heads-up that it will be on sale soon. The Amazon Echo ring will turn yellow when an item goes on sale, so a user knows to ask Alexa to read out their notifications.

This week brought back some of our favorite tech deals we've seen all year. A four pack of Apple's AirTags is back on sale for $89, while the Apple TV 4K has dropped to $130. While neither of those are all-time lows, they're very close and great deals on a couple of the most popular Apple gadgets right now. Amazon also just discounted its Echo smart speaker to $60, which its a record low and a return to its Prime Day price, plus you can still pick up the Chromecast with Google TV for only $40. Here are the best tech deals from this week that you can still get today.

If you missed the chance to pick up an Echo smart speaker during Prime Day last week, you have another opportunity to do so today. Amazon's full-sized Echo is back down to a record-low price of $60, which is 40 percent off its normal rate. The Echo Show 5 is also on sale for $40 right now, which is only $5 more than it was on Prime Day. The Echo Dot, on the other hand, is currently 20 percent off and on sale for $40. You may just think of Amazon's Echo as a way to get Alexa into your home, but it's a pretty capable speaker as well.

While rich, open-domain textual data are generally available and may include interesting phenomena (humor, sarcasm, empathy, etc.) most are designed for language processing tasks, and are usually in a non-conversational format. In this work, we take a step towards automatically generating conversational data using Generative Conversational Networks, aiming to benefit from the breadth of available language and knowledge data, and train open domain social conversational agents. We evaluate our approach on conversations with and without knowledge on the Topical Chat dataset using automatic metrics and human evaluators. Our results show that for conversations without knowledge grounding, GCN can generalize from the seed data, producing novel conversations that are less relevant but more engaging and for knowledge-grounded conversations, it can produce more knowledge-focused, fluent, and engaging conversations. Specifically, we show that for open-domain conversations with 10\% of seed data, our approach performs close to the baseline that uses 100% of the data, while for knowledge-grounded conversations, it achieves the same using only 1% of the data, on human ratings of engagingness, fluency, and relevance.

The future of work is a hot topic among businesses now and has been since the shift to hybrid work. While processes and personnel undergo significant transformations, business and IT leaders must focus intensely on the digital employee experience (DEX) when analyzing and deploying any operational change to the status quo of their current processes. The digital employee experience (DEX) interprets how digital workplace strategies impact employees' overall day-to-day experience. An enterprise's workforce is the bedrock of resilient and sustainable operational shifts. Measurable success cannot be achieved without employees on the same page.

Recent studies have shown that deep neural networks-based recommender systems are vulnerable to adversarial attacks, where attackers can inject carefully crafted fake user profiles (i.e., a set of items that fake users have interacted with) into a target recommender system to achieve malicious purposes, such as promote or demote a set of target items. Due to the security and privacy concerns, it is more practical to perform adversarial attacks under the black-box setting, where the architecture/parameters and training data of target systems cannot be easily accessed by attackers. However, generating high-quality fake user profiles under black-box setting is rather challenging with limited resources to target systems. To address this challenge, in this work, we introduce a novel strategy by leveraging items' attribute information (i.e., items' knowledge graph), which can be publicly accessible and provide rich auxiliary knowledge to enhance the generation of fake user profiles. More specifically, we propose a knowledge graph-enhanced black-box attacking framework (KGAttack) to effectively learn attacking policies through deep reinforcement learning techniques, in which knowledge graph is seamlessly integrated into hierarchical policy networks to generate fake user profiles for performing adversarial black-box attacks. Comprehensive experiments on various real-world datasets demonstrate the effectiveness of the proposed attacking framework under the black-box setting.

This paper presents the findings of an exploratory study on the continuously generating Big Data on Twitter related to the sharing of information, news, views, opinions, ideas, feedback, and experiences about the COVID-19 pandemic, with a specific focus on the Omicron variant, which is the globally dominant variant of SARS-CoV-2 at this time. A total of 12028 tweets about the Omicron variant were studied, and the specific characteristics of tweets that were analyzed include - sentiment, language, source, type, and embedded URLs. The findings of this study are manifold. First, from sentiment analysis, it was observed that 50.5% of tweets had a neutral emotion. The other emotions - bad, good, terrible, and great were found in 15.6%, 14.0%, 12.5%, and 7.5% of the tweets, respectively. Second, the findings of language interpretation showed that 65.9% of the tweets were posted in English. It was followed by Spanish, French, Italian, and other languages. Third, the findings from source tracking showed that Twitter for Android was associated with 35.2% of tweets. It was followed by Twitter Web App, Twitter for iPhone, Twitter for iPad, and other sources. Fourth, studying the type of tweets revealed that retweets accounted for 60.8% of the tweets, it was followed by original tweets and replies that accounted for 19.8% and 19.4% of the tweets, respectively. Fifth, in terms of embedded URL analysis, the most common domain embedded in the tweets was found to be twitter.com, which was followed by biorxiv.org, nature.com, and other domains. Finally, to support similar research in this field, we have developed a Twitter dataset that comprises more than 500,000 tweets about the SARS-CoV-2 omicron variant since the first detected case of this variant on November 24, 2021.

Through generations, the field of artificial intelligence has persevered and become a hugely significant part of modern life. Of the myriad technological advances of the 20th and 21st centuries, one of the most influential is undoubtedly artificial intelligence (AI). From search engine algorithms reinventing how we look for information to Amazon's Alexa in the consumer sector, AI has become a major technology driving the entire tech industry forward into the future. According to a study from Grand View Research, the global AI industry was valued at $93.5 billion in 2021. AI as a force in the tech industry exploded in prominence in the 2000s and 2010s, but AI has been around in some form or fashion since at least 1950 and arguably stretches back even further than that.
