Beat is one of the most exciting companies to ever come out of the ride-hailing space. One city at a time, all across the globe we make transportation affordable, convenient, and safe for everyone. We also help hundreds of thousands of people earn extra income as drivers. Today we are the fastest-growing ride-hailing service in Latin America. But serving millions of rides every day pales in comparison to what lies ahead.

Described as the Airbnb for data scientists, Kaggle is a crowdsourcing platform for aspirants to nurture, train and challenge their learnings. The search for "Kaggle" has increased by 55 percent over five years, and the platform has over 8 million users across 194 countries. While the platform trains several aspirants, it also has many established data scientists. Analytics India Magazine analysed the top 100 Kaggle grandmasters as of April 2022 to explore the top companies represented by them. Here's the latest breakdown of what users do on Kaggle.

The diagnostics plot for this particular model shows a decently good fit . When being used for prediction, it followed the real trend closely. And since our focus is on the estimates/coefficients of the bool_promotion variable, I considered this model good enough to be used in our analysis. As we can see from the model summary, our bool_promotion variable is significant, meaning it's showed to affect sales of grocery I at store 1, and in this case, positively. Having promotions added more than 500 units to the sales for this given combination. Having figured out the pipeline throughout these steps, I automated this process for other store-city-product combinations with auto_arima(), which helps us identify the best fit set of orders, record these orders, as well as coefficients. First, I created a helper function to identify the necessary parameters and train the auto_arima(). One parameter that appeared tricky to me was parameter m, which is the period for seasonal differencing.

As medicine continues to test automated machine learning tools, many hope that low-cost support tools will help narrow care gaps in countries with constrained resources. But new research suggests it's those countries that are least represented in the data being used to design and test most clinical AI -- potentially making those gaps even wider. Researchers have shown that AI tools often fail to perform when used in real-world hospitals. It's the problem of transferability: An algorithm trained on one patient population with a particular set of characteristics won't necessarily work well on another. Those failures have motivated a growing call for clinical AI to be both trained and validated on diverse patient data, with representation across spectrums of sex, age, race, ethnicity, and more.

Worldwide Artificial intelligence (AI) software revenue is forecast to total $62.5 billion in 2022, an increase of 21.3% from 2021, according to a new forecast from Gartner, Inc. Many enterprises are boosting spending on AI as they seek better processes to develop applications. Today's leading AI companies are expanding their technological reach through other technology categories and operations, ranging from predictive analytics to business intelligence to data warehouse tools to deep learning, alleviating several industrial and personal pain points. "The AI software market is picking up speed, but its long-term trajectory will depend on enterprises advancing their AI maturity," said Alys Woodward, senior research director at Gartner. The AI software market encompasses applications with AI embedded in them, such as computer vision software, as well as software that is used to build AI systems.

Clement Delangue, the co-founder and CEO of Hugging Face, has said huge ML models are to machine learning what formula 1 is to the car industry. He laid out his case in a series of tweets: First, like formula 1, it's obviously good PR and branding and very much driven by ego; Second, the resulting models are too costly, unusable and dangerous to use in real life just like you wouldn't drive a Formula 1 car to go to work; however, it's useful in the sense that by pushing everything to the extreme, you learn a ton! To me, huge ML models are to machine learning what formula 1 is to the car industry! Ironically, Delangue's bold statement was another PR stunt. He plugged the BigScience Research Workshop (a gathering of 1,000 researchers around the world.

The metaverse: while some of us are still coming to terms with the idea that we're likely to spend increasing amounts of time in a 3D version of the internet, companies are already scrambling to define the space, carve out their niche, and even snap up virtual real estate. The shift to the metaverse is likely to have a positive business impact, according to 71% of respondents to an Accenture survey, and 42% say it will be "breakthrough" or "transformational." The metaverse will infiltrate every sector in the coming years, culminating in a market opportunity worth more than $1 trillion in annual revenues, according to JP Morgan. Mark Zuckerberg's Meta says the metaverse will be "the biggest opportunity for modern business since the creation of the internet". He has outlined plans to spend more than $10 billion on developing virtual reality software and hardware.

Beneath the buzz, the metaverse is arriving in both predictable and unexpected ways. Some new experiences using headsets and mixed reality will be in your face – quite literally – but other implications will be harder to spot. As with all new categories, we'll see intended and unintended innovations and experiences, and the security stakes will be higher than we imagine at first. There is an inherent social engineering advantage with the novelty of any new technology. In the metaverse, fraud and phishing attacks targeting your identity could come from a familiar face – literally – like an avatar who impersonates your coworker, instead of a misleading domain name or email address.

However, the high cost and low portability/wearability of haptic devices remain unresolved issues, severely limiting the adoption of this otherwise promising technology. Electrotactile interfaces have the advantage of being more portable and wearable due to their reduced actuators' size, as well as their lower power consumption and manufacturing cost. The applications of electrotactile feedback have been explored in human-computer interaction and human-machine-interaction for facilitating hand-based interactions in applications such as prosthetics, virtual reality, robotic teleoperation, surface haptics, portable devices, and rehabilitation. This paper presents a technological overview of electrotactile feedback, as well a systematic review and meta-analysis of its applications for hand-based interactions. We discuss the different electrotactile systems according to the type of application. We also discuss over a quantitative congregation of the findings, to offer a high-level overview into the state-of-art and suggest future directions. Electrotactile feedback systems showed increased portability/wearability, and they were successful in rendering and/or augmenting most tactile sensations, eliciting perceptual processes, and improving performance in many scenarios. However, knowledge gaps (e.g., embodiment), technical (e.g., recurrent calibration, electrodes' durability) and methodological (e.g., sample size) drawbacks were detected, which should be addressed in future studies.

On a sunny morning last December, Iyus Ruswandi, a 35-year-old furniture maker in the village of Gunungguruh, Indonesia, was woken up early by his mother. A technology company was holding some kind of "social assistance giveaway" at the local Islamic elementary school, she said, and she urged him to go. When he got there, representatives of Worldcoin were collecting emails and phone numbers, or aiming a futuristic metal orb at villagers' faces to scan their irises and other biometric data. Two months before Worldcoin appeared in Ruswandi's village, the San Francisco–based company called Tools for Humanity emerged from stealth mode. The company's website described Worldcoin as an Ethereum-based "new, collectively owned global currency that will be distributed fairly to as many people as possible."
