Azure Machine Learning vs IBM Watson: Software comparison


With the ability to revolutionize everything from self-driving cars to robotic surgeons, artificial intelligence is on the cutting edge of tech innovation. Two of the most widely recognized AI services are Microsoft's Azure Machine Learning and IBM's Watson. Both boast impressive functionality, but which one should you choose for your business? Azure Machine Learning is a cloud-based service that allows data scientists or developers to train, build and deploy ML models. It has a rich set of tools that makes it easy to create predictive analytics solutions. This service can be used to build predictive models using a variety of ML algorithms, including regression, classification and clustering.

Woolworths leak says it uses AI and facial recognition -- but the company denies it


A leaked Woolworths employee training module slide claims that it is using "artificial intelligence and facial mapping" in its stores -- but the company denies it is using the technology. This is from a Woolies training module from 2020." At the bottom of the slide, a box titled "Did You Know?" boasts about the company's use of technology to catch offenders: "Our high standard CCTV is already resulting in offenders being arrested by police. We are using technology like artificial intelligence and facial mapping to identify offenders!" Woolworths confirmed that the slide was real, but denied it is using either artificial intelligence or facial recognition to prevent theft.

NeRF: An Eventual Successor for Deepfakes? -


We'll take a deeper look at this proprietary technique when we chat with its creator, in a later article on autoencoder-based deepfakes. However, results as impressive as these are difficult to obtain with standard open source deepfakes software; require expensive and powerful hardware; and usually entail very long training times to obtain very limited sequences. Machine learning models are trained and developed within the capacity of the VRAM and tensor cores on a single video card -- a prospect that becomes more and more challenging in the age of hyperscale datasets, and which presents some specific obstacles to improving deepfake quality. Approaches that shunt training cycles to the CPU, or divide the workload up among multiple GPUs via Data Parallelism or Model Parallelism techniques (we'll examine these more closely in a later article) are still in the early stages. For the near future, a single-GPU training setup remains the most common scenario.

The possibility of general AI


We are excited to bring Transform 2022 back in-person July 19 and virtually July 20 - 28. Join AI and data leaders for insightful talks and exciting networking opportunities. One of the challenges in following the news about developments in the field of artificial intelligence is that the term "AI" is often used indiscriminately to mean two unrelated things. The first use of the term AI is something more precisely called narrow AI. It is powerful technology, but it is also pretty simple and straightforward: You take a bunch of data about the past, use a computer to analyze it and find patterns, and then use that analysis to make predictions about the future. This type of AI touches all our lives many times a day, as it filters spam out of our email and routes us through traffic.

Artificial Intelligence in Society


The artificial intelligence (AI) landscape has evolved significantly from 1950 when Alan Turing first posed the question of whether machines can think. Today, AI is transforming societies and economies. It promises to generate productivity gains, improve well-being and help address global challenges, such as climate change, resource scarcity and health crises. Yet, as AI applications are adopted around the world, their use can raise questions and challenges related to human values, fairness, human determination, privacy, safety and accountability, among others. This report helps build a shared understanding of AI in the present and near-term by mapping the AI technical, economic, use case and policy landscape and identifying major public policy considerations. It is also intended to help co-ordination and consistency with discussions in other national and international fora.

7 of the best handheld vacuums for 2022


Sure, stick vacuums can clean the heck out of your floors and robot vacuum cleaners can do all the dirty work for you without having to get up from the couch. But sometimes, you need a tool that can easily reach awkward spots (like in your car), quickly clean up messy spills, and bust the dust in no time. Handheld vacuums are a great buy because they're some of the most convenient cleaning devices you can own. These tiny workhorses are lightweight and compact, meaning they're easy to store, and you can quickly grab one when your pet knocks over some Cheerios or you need to scurryfunge (i.e., quickly clean when a friend or an in-law is on their way over -- eek) and make countertops, curtains, window sills, and shelves presentable in, like, minutes. But what should you look for in a handheld vacuum?

Machine Learning in Materials Science


Before getting into what polymers are on a molecular level, let's see some familiar materials that are good examples. Some examples of polymers include: plastic, nylon, rubber, wood, protein, and DNA. In this case, we will focus primarily on synthetic polymers like plastic and nylon. At the molecular level, polymers are composed of long chains of repeating molecules. The molecule that repeats in this chain is known as a monomer (or subunit).

Classifying Music Genres with LightGBM


Many machine learning algorithms can perform worse if they deal with data that has an extremely large number of features (dimensions). This is particularly the case if many of those features are highly sparse. This is where dimension reduction can be useful. The idea is to project the high dimensional data into a lower dimension subspace, while retaining as much of the variance present in the data as possible. We will initially use two methods (PCA and t-SNE) to explore whether it is appropriate to use dimension reduction on our lyric data, as well as get an early indication of what a good range of dimensions to reduce into might be.

Papers to Read on Stochastic Gradient Descent


Abstract: We study the Stochastic Gradient Descent (SGD) algorithm in nonparametric statistics: kernel regression in particular. The directional bias property of SGD, which is known in the linear regression setting, is generalized to the kernel regression. More specifically, we prove that SGD with moderate and annealing step-size converges along the direction of the eigenvector that corresponds to the largest eigenvalue of the Gram matrix. These facts are referred to as the directional bias properties; they may interpret how an SGD-computed estimator has a potentially smaller generalization error than a GD-computed estimator. The application of our theory is demonstrated by simulation studies and a case study that is based on the FashionMNIST dataset.

The History of Artificial Intelligence - Science in the News


It began with the "heartless" Tin man from the Wizard of Oz and continued with the humanoid robot that impersonated Maria in Metropolis. By the 1950s, we had a generation of scientists, mathematicians, and philosophers with the concept of artificial intelligence (or AI) culturally assimilated in their minds. One such person was Alan Turing, a young British polymath who explored the mathematical possibility of artificial intelligence. Turing suggested that humans use available information as well as reason in order to solve problems and make decisions, so why can't machines do the same thing? This was the logical framework of his 1950 paper, Computing Machinery and Intelligence in which he discussed how to build intelligent machines and how to test their intelligence.
