Singular value decomposition is a very popular linear algebra technique to break down a matrix into the product of a few smaller matrices. In fact, it is a technique that has many uses. One example is that we can use SVD to discover relationship between items. A recommender system can be build easily from this. In this tutorial, we will see how a recommender system can be build just using linear algebra techniques.

Google is stepping way more ahead by introducing a bunch of new features to their services in India. With these new features, users of Google assistant in India can easily get to set up their vaccination appointment while Google pay users will be able to command in Hinglish (a mixture of English and Hindi) to make any financial transaction. Google pay is now one of the most popular apps for financial transactions in India. So for adding many spices to its feature Google is going to introduce a speech text feature. With this New advanced AI, users just need to command which bank and which account number they want to send money and as soon as the recipient confirms, their money will be sent in seconds.

Artificial Intelligence is a hotter topic today than ever. From self-driving cars to personal assistants, AI is slowly making its way into our daily lives. Artificial Intelligence (AI) is an area of computer science that studies the possibility of thinking computers and machines. There are already many applications in place that have been developed with the help of AI, including business applications. The past decade has seen an explosion of applications for artificial intelligence, machine learning, and deep learning. This has led to advances in a wide range of application domains, including document classification and processing, natural language understanding, and bioinformatics.

If you regularly use an Alexa device, you've probably been upsold by Amazon's assistant at some point. Ask Alexa to carry out some basic task like setting a timer, and it will finish its response with a cheery "By the way, did you know I could [insert feature you've never heard of here]." As highlighted in a recent report from Bloomberg, this is because Amazon knows that users aren't really getting stuck into the full range of Alexa's capabilities. Bloomberg's report is based on internal Amazon docs, and features some interesting statistics about Alexa usage. Taken all together, these statistics don't paint the rosiest picture for Alexa's future.

In recent years, many leading companies have fallen victim to high-profile cyberattacks and data breaches. Cybercriminals and hackers around the world develop new methods and techniques to break into and compromise even the most advanced security systems and gain access to sensitive information. This has led to the exposure of not only trade secrets but also the private information of millions of users. This requires that all organizations stay vigilant and protect themselves. However, not all have the required tools, staff, time and, most importantly, talent and skills needed to overcome these challenges. This has, unfortunately, led some to succumb to cyberattacks.

In a statement, Zurich said that the acquisition would "further enhance" its digital capabilities and help it create "a consistent and efficient approach to developing intelligent virtual assistants across businesses, for both internal and external purposes." "Technology is playing a critical role in advancing Zurich's customer-focused strategy by differentiating the offering, improving the customer experience, and streamlining interactions," Zurich said in its statement. "Conversational AI is central to meeting increasing demand from customers for personalized products and services that are available around the clock." "We have spent decades to learn how to communicate with computers through different programming languages," said Ericson Chan, group information and digital officer at Zurich. "Now it is time for computers to learn how to have a personal conversation with all of us. Natural language processing is key to further enhance customer experience, complementing human interaction in the most natural way. We are very pleased to have AlphaChat join Zurich to help us further advance our digital transformation."

Artificial Intelligence (AI) simply means intelligence in machines, in contrast to natural intelligence found in humans and other natural organisms. Artificial intelligence gained its name and became a formal field of research in 1956, and initial work led to new tools for solving mathematical problems. However, researchers discovered that creating an AI is incredibly difficult, and progress slowed in the 1970s. More recently, increases in computing power and availability of massive data sets have set the groundwork for advances in AI. In particular, scientists have made giant strides in one particular application of AI, machine learning.

There were fierce debates on whether the non-linear embedding propagation of GCNs is appropriate to GCN-based recommender systems. It was recently found that the linear embedding propagation shows better accuracy than the non-linear embedding propagation. Since this phenomenon was discovered especially in recommender systems, it is required that we carefully analyze the linearity and non-linearity issue. In this work, therefore, we revisit the issues of i) which of the linear or non-linear propagation is better and ii) which factors of users/items decide the linearity/non-linearity of the embedding propagation. We propose a novel Hybrid Method of Linear and non-linEar collaborative filTering method (HMLET, pronounced as Hamlet). In our design, there exist both linear and non-linear propagation steps, when processing each user or item node, and our gating module chooses one of them, which results in a hybrid model of the linear and non-linear GCN-based collaborative filtering (CF). The proposed model yields the best accuracy in three public benchmark datasets. Moreover, we classify users/items into the following three classes depending on our gating modules' selections: Full-Non-Linearity (FNL), Partial-Non-Linearity (PNL), and Full-Linearity (FL). We found that there exist strong correlations between nodes' centrality and their class membership, i.e., important user/item nodes exhibit more preferences towards the non-linearity during the propagation steps. To our knowledge, we are the first who design a hybrid method and report the correlation between the graph centrality and the linearity/non-linearity of nodes. All HMLET codes and datasets are available at: https://github.com/qbxlvnf11/HMLET.

The EU has concluded Microsoft's $19.7 billion acquisition of Nuance doesn't pose competition concerns. Nuance gained renown for originally creating the backend of that little old virtual assistant called Siri (you might have heard of it?) The company has since continued to focus on building its speech recognition capabilities and has a number of solutions which span particular industries such as healthcare to general omni-channel customer experience services. Earlier this year, Microsoft decided Nuance is worth coughing up $19.7 billion for. As such large deals often do, the proposed acquisition caught the eyes of several global regulators.
