Amazon Web Services is putting the focus on partners' conversational artificial intelligence (CAI) solutions that could spell the end of organizations' customers screaming "representative" to an interactive voice response phone system or getting stuck in a dead-end or circular digital chat loop. AWS is highlighting solutions from consulting partners including Cation Consulting, Deloitte Consulting, Quantiphi and TensorIoT and technology partners including NLX, ServisBOT and XAPP AI that allow organizations to deploy chatbots, virtual assistants and interactive voice response systems that incorporate AWS artificial intelligence and machine learning services. Their solutions employ services including Amazon Kendra, a machine learning-powered search tool that allows users to search unstructured text using natural language; Amazon Lex, a service for building conversational interfaces into applications using voice and text; and Amazon Polly, a text-to-speech service that converts text into lifelike speech. The new partner initiative comes as the demand for CAI interfaces continues to grow, according to Arte Merritt, who leads AWS partnerships for contact center intelligence and conversational AI. End-customers increasingly prefer to interact with businesses on digital channels, and businesses want to increase user satisfaction, reduce operational costs and streamline business processes, Merritt said in a blog post.

Artificial Intelligence shapes a lot of things we do in our day-to-day lives. The Netflix show you're binge-watching while on quarantine, the compulsive purchases you make on Amazon, and even the things you search on the internet come to us courtesy of AI. Investments in AI and its key subset – machine learning, are increasing more than ever. The total global investments by private businesses on AI accumulated to a total of $70 Billion in 2020. A survey by McKinsey reported that 82% of enterprises using AI and machine learning across their organizational activities have received a significant return on investment.

It is well understood that an individual's health trajectory is influenced by choices made in each moment, such as from lifestyle or medical decisions. With the advent of modern sensing technologies, individuals have more data and information about themselves than any other time in history. How can we use this data to make the best decisions to keep the health state optimal? We propose a generalized Personal Health Navigation (PHN) framework. PHN takes individuals towards their personal health goals through a system which perpetually digests data streams, estimates current health status, computes the best route through intermediate states utilizing personal models, and guides the best inputs that carry a user towards their goal. In addition to describing the general framework, we test the PHN system in two experiments within the field of cardiology. First, we prospectively test a knowledge-infused cardiovascular PHN system with a pilot clinical trial of 41 users. Second, we build a data-driven personalized model on cardiovascular exercise response variability on a smartwatch data-set of 33,269 real-world users. We conclude with critical challenges in health computing for PHN systems that require deep future investigation.

Most of the existing recommender systems are based only on the rating data, and they ignore other sources of information that might increase the quality of recommendations, such as textual reviews, or user and item characteristics. Moreover, the majority of those systems are applicable only on small datasets (with thousands of observations) and are unable to handle large datasets (with millions of observations). We propose a recommender algorithm that combines a rating modelling technique (i.e., Latent Factor Model) with a topic modelling method based on textual reviews (i.e., Latent Dirichlet Allocation), and we extend the algorithm such that it allows adding extra user- and item-specific information to the system. We evaluate the performance of the algorithm using Amazon.com datasets with different sizes, corresponding to 23 product categories. After comparing the built model to four other models we found that combining textual reviews with ratings leads to better recommendations. Moreover, we found that adding extra user and item features to the model increases its prediction accuracy, which is especially true for medium and large datasets.

Machine learning is one of the important areas of AI. It plays an important role in identifying the trends and behavior of a mass of people using a given dataset. Aces like Google, Facebook, Uber, and many other leading companies use machine learning as the backbone of their operations. Overall, machine learning is a highly sought after skill these days. The more demand for this domain and its use, the more intimidating it becomes for newbies to learn.

NVIDIA has set the stage for businesses worldwide to design and deploy large language models (LLMs). This design enables them to develop domain-specific chatbots, personal assistants, and other artificial intelligence systems. The firm announced the NVIDIA NeMo Megatron framework for training trillion-parameter language models. In addition, NVIDIA Triton Inference Server offers multi-node distributed inference features for new domains and languages. When used in conjunction with NVIDIA DGX systems, these technologies provide an enterprise-grade solution for simplifying the construction and deployment of massive language models.

Picture a machine learning system that relies on crowdsourced data labelers to help rank music recommendations. Labellers are all different and this difference may manifest in their labels. The answer depends on many things, but one of them is who you are asking. Bias means different things to different people. The other day I watched a very interesting discussion along these lines between a lawyer (Jake Goldenfein) and a data scientist (Danula Hettiachchii). It seemed like my colleagues had fundamentally different ideas about bias.

The Portal Plus is an expensive device with a $349 price tag that belies its capabilities. Although the Portal Plus boasts a big screen and some fun tools, it's far more limited than, say, the current-generation Amazon Echo Show 10 and Google Nest Hub Max. In fact, the big screen is arguably the sole reason to choose the Portal Plus over Facebook's $199 Portal Go, a nearly identical device save for its 10-inch display and battery-powered portability. Whether or not you'll be truly satisfied with either one, though, depends on what you want--and whether you have a Facebook or WhatsApp account, one of which is required to use any Portal. The Portal Plus' base is also its speaker.

Artificial intelligence is a brain created by humans that can think and make decisions for itself, often to assist humans and improve our everyday lives. Think of it as when you're just born baby, you see many things, but don't know what to do with it. But with the help of your parents, teachers, and friends you learn how to talk, eat, and think for yourself. AI without code is literally that. It's the developers job to teach the program how to think and real with the data given.

Step-By-Step Guide to Build Collaborative Filtering and Association Rule Based Recommender Using Fastai and Python. Recommender system is a promising approach to boost sales to the next level by suggesting the right products to the right customers. This course starts by showing you the main solutions of recommender systems in the industry and the hypotheses behind the main solutions. You'll then learn how to build collaborative filtering models with fastai, and exercise the trained model on test datasets. As you advance, you'll visualize latent features, interpret weights and biases, and check what similar users/Items are from the model's perspective.
