Three opportunities of Digital Transformation: AI, IoT and Blockchain

#artificialintelligence

Koomey's law This law posits that the energy efficiency of computation doubles roughly every one-and-a-half years (see Figure 1–7). In other words, the energy necessary for the same amount of computation halves in that time span. To visualize the exponential impact this has, consider the face that a fully charged MacBook Air, when applying the energy efficiency of computation of 1992, would completely drain its battery in a mere 1.5 seconds. According to Koomey's law, the energy requirements for computation in embedded devices is shrinking to the point that harvesting the required energy from ambient sources like solar power and thermal energy should suffice to power the computation necessary in many applications. Metcalfe's law This law has nothing to do with chips, but all to do with connectivity. Formulated by Robert Metcalfe as he invented Ethernet, the law essentially states that the value of a network increases exponentially with regard to the number of its nodes (see Figure 1–8).


The best smart lights you can buy

Engadget

One of the best places to start when building a smart home ecosystem is smart lights. Not only are they relatively affordable compared to other IoT gadgets, often costing between $10 and $50 a bulb, but they can also completely change the feel of your home. You can go from boring and analogue to colorful and automated within minutes, and there are endless possibilities when it comes to creating funky-colored light scenes, setting schedules and more. But like the rest of the smart home space over the last few years, there are now more players in smart lighting than ever before. We tested out some of the most popular smart lights on the market and found that most of them are quite good, but there are differences in compatibility, color quality and mobile app usability that are worth considering before deciding which system will be right for your home.


Artificial Intelligence Is the Next Step for Smart Homes

#artificialintelligence

In recent years, homeowners have adopted smart home technologies to improve their quality of life. Connected devices and appliances perform actions, tasks, and automated routines based on a homeowner's preferences. Smart technologies enable homeowners to save time, money, and energy. Major tech companies such as Apple, Google, and Amazon have driven the adoption of smart home technologies. From digital voice assistants to intelligent thermostats and everything in between, smart homes are the homes of the future.


Sonos' Roam SL is a mic-free version of its portable speaker

Engadget

It's been about a year since Sonos released the Roam, the company's smallest and least expensive speaker yet. As with most modern Sonos speakers, the Roam has a built-in microphone that lets you use the speaker with Amazon's Alexa or the Google Assistant. Today, Sonos is releasing a variant of the Roam that omits that microphone, the Roam SL. Aside from removing the microphone, the $159 Roam SL is identical to the original Roam, which costs $20 more. It's a small speaker that can connect to your WiFi network and be part of a Sonos multi-room audio system. But it also has a built-in battery and Bluetooth capabilities, so you can take it with you and use it away from a WiFi connection.


Syncing Alexa, Google Nest and Apple smart home tech is about to get easier with Matter

USATODAY - Tech Top Stories

Chances are, if you're reading this article, you have at least one smart home device in your household. After all, according to several studies on the topic, nearly half of U.S. households currently have at least one. From smart speakers and connected thermostats to light bulbs and video cameras, these gadgets have quickly moved from cutting edge to mainstream. If you have multiple smart devices in your home, you've likely discovered what's keeping much of the remaining half of U.S. households from buying their first one. It's hard to make them work together.

Why it matters having Matter support for your new smart home device – TechCrunch

#artificialintelligence

As companies unveil their new smart home devices at the 2022 CES tech show, underway now in Las Vegas, much of the hype involves Matter, an open-source connectivity standard built around a shared belief that smart home devices should seamlessly integrate with other systems and be secure and reliable. If you like devices, you are probably among the 66% of households that have smart home devices, according to Deloitte. We also know you don't just stick with one company or brand, but probably have purchased from at least half a dozen different companies. That's why for any company launching a smart home device this year, having Matter support will be helpful. Not only is the protocol being developed by some of the biggest tech companies -- think Apple, Amazon and Google -- and smart home device makers, it is designed to finally fix the issues around fragmented smart home systems so that all of your devices can be easily set up and routed from one place.


Challenges of Artificial Intelligence -- From Machine Learning and Computer Vision to Emotional Intelligence

arXiv.org Artificial Intelligence

Artificial intelligence (AI) has become a part of everyday conversation and our lives. It is considered as the new electricity that is revolutionizing the world. AI is heavily invested in both industry and academy. However, there is also a lot of hype in the current AI debate. AI based on so-called deep learning has achieved impressive results in many problems, but its limits are already visible. AI has been under research since the 1940s, and the industry has seen many ups and downs due to over-expectations and related disappointments that have followed. The purpose of this book is to give a realistic picture of AI, its history, its potential and limitations. We believe that AI is a helper, not a ruler of humans. We begin by describing what AI is and how it has evolved over the decades. After fundamentals, we explain the importance of massive data for the current mainstream of artificial intelligence. The most common representations for AI, methods, and machine learning are covered. In addition, the main application areas are introduced. Computer vision has been central to the development of AI. The book provides a general introduction to computer vision, and includes an exposure to the results and applications of our own research. Emotions are central to human intelligence, but little use has been made in AI. We present the basics of emotional intelligence and our own research on the topic. We discuss super-intelligence that transcends human understanding, explaining why such achievement seems impossible on the basis of present knowledge,and how AI could be improved. Finally, a summary is made of the current state of AI and what to do in the future. In the appendix, we look at the development of AI education, especially from the perspective of contents at our own university.
