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.

Welcome to the first course in Term 2 as part of the series "MBA in Artificial Intelligence Digital Marketing". Artificial Intelligence (AI) seems to be a unique technology of making a machine, a robot fully autonomous. AI is an analysis of how the machine is thinking, studying, determining, and functioning when it is trying to solve problems. These kinds of problems are present in all fields, the most emerging ones, and even beyond. The aim of Artificial Intelligence is to enhance machine functions relating to human knowledge, such as reasoning, learning, and problems along with the ability to manipulate things.

Version control tracks and manages changes in a collection of related entities. It records changes and modifications over time, so you can recall, revert, compare, reference, and restore anything you want. Version control is also known as source control or revision control. Each version is associated with a timestamp, and the ID of the person making the changes in documents, computer programs, files, etc. Version control prevents conflicts in concurrent work, and enables a platform for better decision-making and fostering compatibility. Version Control Systems (VCM) run as stand-alone software tools that implement a systematic approach to track, record, and manage changes made to a codebase. In this article, we're going to explore what version control means from different perspectives. This version control system consists of a local database on your computer that stores every file change as a patch (difference between files in a unique format).
