Accuracy

Artificial intelligence has permeated every technology field today. Among them, one field which is particularly resilient to emerging technologies is the medical field. Due to dealing in extremely sensitive areas that can lead to life-and-death scenarios, the medical field has been apprehensive about deploying new medtech tools into general practice. However, AI has been knocking at its door for some time, and if a new study conducted by Google researchers is to be believed, Google's in-house Med-PaLM 2 is getting really…

A computer algorithm developed using artificial intelligence accurately distinguished real heart attacks from false alarms, according to an emergency room study that offers a way for overburdened doctors to focus on the sickest patients.The algorithm was able to accurately rule out a heart attack in nearly all patients, according to the study published Thursday in Nature Medicine. The tool, tested in more than 10000 patients in six countries, was 99.6% accurate in ruling out patients who weren't suffering from heart…

Machine learning has undoubtedly become a powerful tool in today’s data-driven world, but are we truly tapping into its full potential? Traditional evaluation metrics like accuracy, precision, and recall have long held the spotlight, but there’s so much more to consider when measuring a model’s real-world impact. In this article, we’ll dive into the lesser-known, unconventional metrics that are reshaping the way we assess machine learning models. From fairness, privacy and calibration, to enery consumption, data…

What’s the cost of being wrong (and the gain of being right) according to different metricsIf you google “What metric is better, accuracy or F1-score?” you will probably find an answer like:“If your dataset is unbalanced, forget accuracy and go for F1-score.”If you look for explanations, you will probably find a vague reference to the “different costs” associated with false negatives and false positives. But the sources do not state clearly which these costs are in the different metrics.This is why I felt the need to…

In seeking a safe yet effective way to predict Alzheimer's disease, researchers found a sugar molecule in the blood of affected patients. When combined with a simple memory test and genetic analysis, the research team was able to predict the onset of the condition up to a decade in advance with a significant degree of accuracy. The protocol could soon join others in helping scientists spot Alzheimer's in advance of its symptoms and take steps to halt its progression.It seems that almost daily, scientists are getting…

To spot a liar, ignore everything except the level of detail in a person's story, new research suggests.If a person provides rich descriptions of who, what, when, how, and why, it's likely they are telling the truth. If they skim over these details, they are probably lying.Using this very simple test and nothing else, people can separate truth from lies with nearly 80 percent accuracy, researchers from the University of Amsterdam have found.When it comes to catching liars, we usually try to employ as many tell-tale signs…

via Buena Vista Pirates of the Caribbean: Curse of the Black Pearl deservedly takes most of the plaudits for launching the old-fashioned swashbuckler to heights it hadn’t experienced in decades. However, as well as Martin Campbell’s fantastic The Mask of Zorro, but Kevin Reynolds’ 2002 adaptation of The Count of Monte Cristo shouldn’t be forgotten about, either. As you’d expect from the regular Kevin Costner collaborator responsible for Waterworld and Robin Hood: Prince of Thieves, the visuals are suitably…

Researchers used highly sensitive imaging techniques and developed machine learning methods that can identify compostable plastics among conventional types.Researchers have created classification models that enable accurate and automated sorting of various types of plastics.The use of compostable plastics is increasing, and while they offer several benefits, these materials, such as wrappers and packaging, can mix with and contaminate traditional plastic waste during recycling. To address this issue, scientists have…

US researchers have developed a novel Artificial Intelligence-based tool that has shown 90 per cent accuracy in detecting Alzheimer`s disease from routinely collected clinical brain images. The tool, developed by a team at Massachusetts General Hospital (MGH), may help clinicians identify patients who would benefit from treatment. The results, published in the journal PLOS ONE, showed that the toll was able to detect Alzheimer`s disease regardless of other variables, such as age. "Alzheimer`s disease typically occurs…

The findings suggest that fake news thrives on social media not only because people are…
