Removal of Batch Effects using Generative Adversarial Networks

arXiv.org Machine Learning

Many biological data analysis processes like Cytometry or Next Generation Sequencing (NGS) produce massive amounts of data which needs to be processed in batches for down-stream analysis. Such datasets are prone to technical variations due to difference in handling the batches possibly at different times, by different experimenters or under other different conditions. This adds variation to the batches coming from the same source sample. These variations are known as Batch Effects. It is possible that these variations and natural variations due to biology confound but such situations can be avoided by performing experiments in a carefully planned manner. Batch effects can hamper down-stream analysis and may also cause results to be inconclusive. Thus, it is essential to correct for these effects. Some recent methods propose deep learning based solution to solve this problem. We demonstrate that this can be solved using a novel Generative Adversarial Networks (GANs) based framework. The advantage of using this framework over other prior approaches is that here we do not require to choose a reproducing kernel and define its parameters.We demonstrate results of our framework on a Mass Cytometry dataset.


Predicting wind pressures around circular cylinders using machine learning techniques

arXiv.org Machine Learning

Numerous studies have been carried out to measure wind pressures around circular cylinders since the early 20th century due to its engineering significance. Consequently, a large amount of wind pressure data sets have accumulated, which presents an excellent opportunity for using machine learning (ML) techniques to train models to predict wind pressures around circular cylinders. Wind pressures around smooth circular cylinders are a function of mainly the Reynolds number (Re), turbulence intensity (Ti) of the incident wind, and circumferential angle of the cylinder. Considering these three parameters as the inputs, this study trained two ML models to predict mean and fluctuating pressures respectively. Three machine learning algorithms including decision tree regressor, random forest, and gradient boosting regression trees (GBRT) were tested. The GBRT models exhibited the best performance for predicting both mean and fluctuating pressures, and they are capable of making accurate predictions for Re ranging from 10^4 to 10^6 and Ti ranging from 0% to 15%. It is believed that the GBRT models provide very efficient and economical alternative to traditional wind tunnel tests and computational fluid dynamic simulations for determining wind pressures around smooth circular cylinders within the studied Re and Ti range.

Mountaineer develops new model for environmental and energy uses – Tech Check News

#artificialintelligence

A new machine-learning model developed by a West Virginia University student has the potential for energy, environmental and even healthcare applications. The model, which can be used to predict the adsorption energies, i.e. adhesive capabilities in gold nanoparticles, was developed by Gihan Panapitiya, a doctoral physics student from Sri Lanka. Gold nanoparticles have historically been used by artists to bring out vibrant colors via their interaction with light. Now they are increasingly used in high technology applications, electronic conductors and others. "Machine learning recently came into the spotlight, and we wanted to do something linking machine learning with gold nanoparticles as catalysts," he said.


The Incredible Ways Shell Uses Artificial Intelligence To Help Transform The Oil And Gas Giant

#artificialintelligence

Royal Dutch Shell is heavily investing in research and development of artificial intelligence (AI), which it hopes will provide solutions to some of its most pressing challenges. From meeting the demands of a transitioning energy market, urgently in need of cleaner and more efficient power, to improving safety on the forecourts of its service stations, AI is at the top of the agenda. I have been working with Shell over the past months to help create a data strategy, which gave me a thorough insight into Shell's AI priorities and initiatives. Current initiatives include deploying reinforcement learning in its exploration and drilling program, to reduce the cost of extracting the gas that still drives a significant proportion of its revenues. Elsewhere across its global business, Shell is rolling out AI at its public electric car charging stations, to manage the shifting demand for power throughout a day.


6 Renewable Energy Trends To Watch In 2019

#artificialintelligence

An increasing number of countries, companies and regions are embracing sustainable energy generation and the landscape is rapidly evolving. Here are 6 renewable energy trends to watch in the coming year. Renewable energy is booming in China.Getty Energy storage plays an important role in balancing power supply and demand, and is key to tackling the intermittency issues of renewable energy. Pairing a storage system with a renewable energy source ensures a smooth and steady power supply, even when weather conditions are not optimal for energy generation. Batteries are the most common storage devices used in renewable energy systems and their use is increasing on both the residential and grid-wide scale.


These maps show you every tree in your city

#artificialintelligence

"You can use either aerial imagery or satellite imagery to do basically the same task, but a lot faster," says Aidan Swope, a Caltech undergrad who created the algorithm as an intern at the tech startup Descartes Labs. Because taking a census by hand takes months or years, some trees are inevitably cut down before it's complete, so the final map won't be completely accurate. And these censuses typically also only include street trees, not trees in parks or on private property, while the algorithm includes everything. The tool uses a convolutional neural network, similar to those used for facial recognition. While it's not hard for a machine to find green areas in an aerial image, Swope also trained the model with lidar data, a type of remote sensing data that shows height, making it possible to distinguish trees from grass or other plants.


Artificial Intelligence is the New Business as Usual

#artificialintelligence

Artificial Intelligence (AI) is all around us. Of course, plots involving some form of AI-driven machine run-amuck are center stage in every other sci-fi movie and that's what may come to mind for some of us. Indeed, a significant percentage of the population is unaware that AI plays a central role in the everyday functions of most tech giants and many utilities. For example: AI algorithms drive the search capabilities of Google Assistant; Alexa, Amazon's intelligent voice assistant, uses neural networks to power natural language processing to analyze the human voice and respond logically. Microsoft uses AI for Bing, to power chatbots in Skype and analyze data in Office 365; and the list goes on with Apple, IBM, Facebook, Uber and many others using AI to run their businesses and offer services to customers.

Underwater artificial intelligence research continues Government Europa

#artificialintelligence

Underwater artificial intelligence would enable unmanned devices to map sea beds and carry out underwater infrastructure repair, both of which can be dangerous to human technicians. The UK's technology and robotics sector has been working to introduce elements of artificial intelligence and machine learning into infrastructure maintenance on land, at sea and in space; with the goal of reducing the disruption, costs and risks posed to humans by conducting this maintenance. By introducing underwater artificial intelligence and 3D computer imaging technologies to the subaquatic robotics sector, researchers hope to reduce the cost of producing offshore renewable energies. UK robotics businesses such as Rovco, which specialises in subsea robotics services, have received funding from UN government initiatives for research and development of emerging technologies; working alongside other researchers, engineers and industry specialists to develop innovative, collaborative projects. In a blog written on the underwater artificial intelligence project for Innovate UK, Rovco's Chief Technology Officer Dr Iain Wallace said: "The ability to work with other like-minded engineers, R&D teams, and Remotely Operated Vehicles (ROV) specialists has resulted in exciting project concepts, allowing us to innovate further and more efficiently. We see collaboration as not only useful, but crucial if new technology is going to positively impact a range of sectors including nuclear, energy and robotics. This innovation has then brought in external investment to Rovco, growing the company and creating many high-tech robotics jobs – with our hiring continuing."
