Today, the terms artificial intelligence (AI) and machine learning (ML) are often used interchangeably. While the terms are related, they mean different things. We map out how they all relate to one another, so your team can find the best candidates, best approaches and best frameworks as you embark upon your AI journey. AI refers to the concept of machines mimicking human cognition. To reference artificial intelligence is to allude to machines performing tasks that only seemed plausible with human thinking and logic.

Upper gastrointestinal cancers (including oesophageal cancer and gastric cancer) are the most common cancers worldwide. Artificial intelligence platforms using deep learning algorithms have made remarkable progress in medical imaging but their application in upper gastrointestinal cancers has been limited. We aimed to develop and validate the Gastrointestinal Artificial Intelligence Diagnostic System (GRAIDS) for the diagnosis of upper gastrointestinal cancers through analysis of imaging data from clinical endoscopies.

At a high level, neural nets learn through trial and error. A network is presented with a task, and is "graded" on whether it performs the task correctly or not. The network learns by continually attempting these tasks and adjusting itself based on its grades, such that it becomes more likely to perform correctly in the future. A network's performance depends heavily on its training regimen. For example, a researcher can tweak how much a network adjusts itself after each task–referred to as its learning rate.

A NASA Frontier Development Lab (FDL) team has shown that by using deep learning, it is possible to virtually monitor the Sun's extreme ultraviolet (EUV) irradiance, which is a key driver of space weather. The Sun is vital for survival, but solar flares, which typically occur a few times a year, have the potential to cause severe disruptions in space and on Earth. These disruptions can impact spacecraft, satellites and even systems here on Earth, including GPS navigation, radio communications and the power grid. Deep learning can help get more value out of our current ability to monitor the Sun by providing virtual instruments to supplement physical devices. This research will be published in Science Advances on October 2, 2019 ("A deep learning virtual instrument for monitoring solar extreme ultraviolet spectral irradiance").

Gary Marcus is a professor emeritus at NYU, founder of Robust.AI and Geometric Intelligence, the latter is a machine learning company acquired by Uber in 2016. He is the author of several books on natural and artificial intelligence, including his new book Rebooting AI: Building Machines We Can Trust. Gary has been a critical voice highlighting the limits of deep learning and discussing the challenges before the AI community that must be solved in order to achieve artificial general intelligence. This conversation is part of the Artificial Intelligence podcast.

The two areas of Artificial Intelligence, namely machine learning and deep learning, raise more questions than an entire field combined, mainly because these two areas are often mixed up and used interchangeably when referring to statistical modeling of data; however, the techniques used in each are different and you need to understand the distinctions between these data modeling paradigms in order to refer to them by their corresponding name. In this article, we'll explain the definitions of artificial intelligence, machine learning, deep learning, and neural networks, briefly overview each of those categories, explain how they work, and finish with an explicit comparison of machine learning vs deep learning. Artificial Intelligence (hereafter referred to as AI) is the intelligence demonstrated by machines as opposed to the natural intelligence of humans. AI can be further classified into three different systems: analytical, human-inspired, and humanized artificial intelligence.

The predicted economic impact of AI is huge. It's also a game-changer that can reshape the competitive landscape in every major industry. McKinsey predicts deep learning will generate up to $5.8 trillion in annual economic value. But, for your business to realize any of this value, you have to operationalize machine learning. Download our whitepaper, "Why Your Business Needs a Machine Learning Platform" to learn about the growth of AI across industries and why you need a platform to operationalize the machine learning lifecycle.

The problem as far as I can see is that far too few papers use a basic and simple baseline to compare against as a control. They are always comparing against the state of the art and previous DL techniques, but rarely to do they include basic correlation analysis, linear / logistic regressions, etc., as a basis for comparison. In statistics one doesn't just say "we got X performance which was better than Y performance", one says "we show that the effect size is better than control by X amount, and confirm that this actually represents an improvement and is not likely a bias induced by random sampling of the data with 95% confidence." But DL papers often just include final test set performance and traces of loss function per iteration, and say, look X learns faster than Y and Z and ends up with less error. Often this is even done without confidence intervals, which, for methods that depend on random initial conditions, is a sin.

Recently, Lancet Digital Health ran a meta-analysis concluding -- if cautiously -- that "deep learning" (more familiarly known as artificial intelligence) can be considered "equivalent to healthcare professionals" in image-based diagnoses. In an editorial commentary on the analysis, Tessa Cook says, in effect, "not so fast!"
