Spectrum coexistence is essential for next generation (NextG) systems to share the spectrum with incumbent (primary) users and meet the growing demand for bandwidth. One example is the 3.5 GHz Citizens Broadband Radio Service (CBRS) band, where the 5G and beyond communication systems need to sense the spectrum and then access the channel in an opportunistic manner when the incumbent user (e.g., radar) is not transmitting. To that end, a high-fidelity classifier based on a deep neural network is needed for low misdetection (to protect incumbent users) and low false alarm (to achieve high throughput for NextG). In a dynamic wireless environment, the classifier can only be used for a limited period of time, i.e., coherence time. A portion of this period is used for learning to collect sensing results and train a classifier, and the rest is used for transmissions. In spectrum sharing systems, there is a well-known tradeoff between the sensing time and the transmission time. While increasing the sensing time can increase the spectrum sensing accuracy, there is less time left for data transmissions. In this paper, we present a generative adversarial network (GAN) approach to generate synthetic sensing results to augment the training data for the deep learning classifier so that the sensing time can be reduced (and thus the transmission time can be increased) while keeping high accuracy of the classifier. We consider both additive white Gaussian noise (AWGN) and Rayleigh channels, and show that this GAN-based approach can significantly improve both the protection of the high-priority user and the throughput of the NextG user (more in Rayleigh channels than AWGN channels).

Due to the popularity of data science, machine learning, advanced analytics, machine learning, and artificial intelligence, people who are more interested in these fields have many important questions to consider. This includes choosing the best programming language or deciding which frameworks, APIs, and platforms to use for a specific scenario or task. This article will help you to choose the best programming language for your project if you're thinking about developing artificial intelligence solutions. They are both very popular and widely used tools among developers. Both languages are free and open-source.

With the high rise in demand for talent in the field of Artificial Intelligence (AI), the need for professionals who have expertise in this field has also increased immensely. Worldwide, many organizations are on the lookout for individuals who possess a great skillsets in the field of AI. This demand gave rise to the artificial intelligence engineer certification program, which is offered by several online learning institutes. If a person wants to enhance their skill set and also stay ahead in the growing populations then doing a certification program in the field of AI is the best choice. In this article, let's understand the most affordable and industry-recognized top AI certifications that one can do to jump the career ladder.

The random seed is a number that's used to initialize the pseudorandom number generator. It can have a huge impact on the training results. There are different ways that the pseudorandom number generator can be used in ML. As you can see, the random seed can have an influence on the result of training in several ways and add a huge variance. One thing you do not need when tuning hyper-parameters is variance.

Businesses are using artificial intelligence for many different tasks in the everyday work environment and beyond. While developers have yet to fully harness the power of artificial intelligence, its use cases continue to grow at an exponential rate. AI is the widely-encompassing branch of computer science concerned with the building of smart machines. These machines typically required human intelligence in the past. As an interdisciplinary science, artificial intelligence has many different approaches to its technology and practices.

Deep Learning vs. Machine Learning: You'll learn how the two concepts compare and how they fit into the broader category of Artificial Intelligence. During this demo we will also describes how deep learning can be applied to real-world scenarios such as fraud detection, voice and facial recognition, sentiment analytics, and time series forecasting.

It's trended at around $600 when in stock in recent months, and while at just under 50 inches it's a little on the small side, if you have a smaller space or just don't want your TV to overwhelm the rest of your decor, it's a nice option at this discounted price for those who like to game.

Smart home enthusiasts take note: You can tie Ambient Weather's WS-2902 Osprey weather station into your smart home system, so your indoor lights won't wait until sunset to turn on when it's gray and dreary outside; your smart sprinkler will stop watering the lawn if it starts to rain; and you can ask Alexa or Google Assistant for a weather report from where you actually live, not from the closest National Weather Service (NWS) monitoring station. You'd think most home weather stations do these things, but they don't. Netatmo comes close, with hooks into Samsung SmartThings and IFTTT, but you'll spend more than $300 to build out a complete Netatmo system that can measure temperature, rainfall, and wind speed. The WS-2902 Osprey is built with connectivity top of mind. It's Wi-Fi capable and it works with IFTTT, so you can program weather events and conditions to trigger actions in your smart home.

Looking forward to upcoming technologies and getting hold of them in the early days is the best way to make money. The new report by Forbes has claimed that people working on the blockchain, AI, machine learning and IOE will be earning a lot in 2018. The system or technology on which cryptos are based is Blockchain. This past year, we started seeing some early proof points of how this new infrastructure can be used, including the announcement by the Australian Securities Exchange that it would replace its current post-trade settlement process with a blockchain system. Blockchain will completely free itself of its singular cryptocurrency identity in 2018 and will emerge as the latest financial inclusion technology.

Reaching an optimal shared decision in a distributed way is a key aspect of many multi-agent and swarm robotic applications. As humans, we often have to come to some conclusions about the current state of the world so that we can make informed decisions and then act in a way that will achieve some desired state of the world. Of course, expecting every person to have perfect, up-to-date knowledge about the current state of the world is unrealistic, and so we often rely on the beliefs and experiences of others to inform our own beliefs. We see this too in nature, where honey bees must choose between a large number of potential nesting sites in order to select the best one. When a current hive grows too large, the majority of bees must choose a new site to relocate to via a process called "swarming" – a problem that can be generalised to choosing the best of a given number of choices.
