To conclude, our study showed that medical AI systems can easily learn to recognise self-reported racial identity from medical images, and that this capability is extremely difficult to isolate,


Image Classification in Machine Learning [Intro + Tutorial]

#artificialintelligence

Image Classification is one of the most fundamental tasks in computer vision. It has revolutionized and propelled technological advancements in the most prominent fields, including the automobile industry, healthcare, manufacturing, and more. How does Image Classification work, and what are its benefits and limitations? Keep reading, and in the next few minutes, you'll learn the following: Image Classification (often referred to as Image Recognition) is the task of associating one (single-label classification) or more (multi-label classification) labels to a given image. Here's how it looks like in practice when classifying different birds-- images are tagged using V7. Image Classification is a solid task to benchmark modern architectures and methodologies in the domain of computer vision. Now let's briefly discuss two types of Image Classification, depending on the complexity of the classification task at hand. Single-label classification is the most common classification task in supervised Image Classification.


Autonomous Vehicle with 2D Lidar

#artificialintelligence

Lidar is an acronym for light detection and ranging. Lidar is like radar, except that it uses light instead of radio waves. The light source is a laser. A lidar sends out light pulses and measures the time it takes for a reflection bouncing off a remote object to return to the device. As the speed of light is a known constant, the distance to the object can be calculated from the travel time of the light pulse (Figure 1).


Protecting payments in an era of deepfakes and advanced AI

#artificialintelligence

In the midst of unprecedented volumes of e-commerce since 2020, the number of digital payments made every day around the planet has exploded – hitting about $6.6 trillion in value last year, a 40 percent jump in two years. With all that money flowing through the world's payments rails, there's even more reason for cybercriminals to innovate ways to nab it. To help ensure payments security today requires advanced game theory skills to outthink and outmaneuver highly sophisticated criminal networks that are on track to steal up to $10.5 trillion in "booty" via cybersecurity damages, according to a recent Argus Research report. Payment processors around the globe are constantly playing against fraudsters and improving upon "their game" to protect customers' money. The target invariably moves, and scammers become ever more sophisticated.


The Future of Artificial Intelligence in Manufacturing Industries

#artificialintelligence

Artificial intelligence (AI) is now transforming the manufacturing industry. AI can extend the sheer reach of potential applications in the manufacturing process from real-time equipment maintenance to virtual design that allows for new, improved, and customized products to a smart supply chain and the creation of new business models. Artificial intelligence (AI) in the manufacturing industry is being used across a variety of different application cases. It is being used as a way to enhance defect detection through sophisticated image processing algorithms that can then automatically categorize defects across any industrial object that it sees. The term artificial intelligence is used because these machines are artificially incorporated with human-like to perform tasks as we do.

CLIP-GEN Overview

#artificialintelligence

Training a text-to-image generator in the general domain like DALL-E, GauGAN, and CogView requires huge amounts of paired text-image data, which can be problematic and expensive. In this paper, the authors propose a self-supervised scheme named CLIP-GEN for general text-to-image generation with the language-image priors extracted with a pre-trained CLIP model. Only a set of unlabeled images in the general domain is required to train a text-to-image generator. First, the embedding of the image in the united language-vision embedding space is extracted with the CLIP encoder. Next, the image is converted into a sequence of discrete tokens in the VQGAN codebook space (the VQGAN can be trained using unlabeled data).


Image Classification with Convolutional Neural Networks (CNNs) - KDnuggets

#artificialintelligence

A Convolutional Neural Network is a special class of neural networks that are built with the ability to extract unique features from image data. For instance, they are used in face detection and recognition because they can identify complex features in image data. Like other types of neural networks, CNNs consume numerical data. Therefore, the images fed to these networks must be converted to a numerical representation. Since images are made up of pixels, they are converted into a numerical form that is passed to the CNN.


Are You Better Than a Machine at Spotting a Deepfake?

#artificialintelligence

Sarah Vitak: This is Scientific American's 60 Second Science. Early last year a TikTok of Tom Cruise doing a magic trick went viral. I mean, it's all the real thing."] Matt Groh: A deepfake is a video where an individual's face has been altered by a neural network to make an individual do or say something that the individual has not done or said. Vitak: That is Matt Groh, a Ph.D. student and researcher at the M.I.T. Media Lab. Groh: It seems like there's a lot of anxiety and a lot of worry about deepfakes and our inability to, you know, know the difference between real or fake. Vitak: But he points out that the videos posted on the Deep Tom Cruise account aren't your standard deepfakes. The creator, Chris Umé, went back and edited individual frames by hand to remove any mistakes or flaws left behind by the algorithm. It takes him about 24 hours of work for each 30-second clip. It makes the videos look eerily realistic. But without that human touch, a lot of flaws show up in ...
