How AI Can Reduce Electricity Theft
Since renewable energy is more economically feasible, this has led to self-generation, with solar panels or wind turbines on the roof of our home. We hope that such installations will reduce our energy bills while helping the planet and everything at the same time. If we cannot save the electricity generated, Then it will fall and power theft is a surprisingly big thing. The Revenue Protection Association estimates that such theft costs 40 440 million a year in the UK alone. In Brazil, Electrobras claims that 22% of its electricity is lost due to fraud and theft.
Guided by AI, robotic platform automates molecule manufacture
Guided by artificial intelligence and powered by a robotic platform, a system developed by MIT researchers moves a step closer to automating the production of small molecules that could be used in medicine, solar energy, and polymer chemistry. The system, described in the August 8 issue of Science, could free up bench chemists from a variety of routine and time-consuming tasks, and may suggest possibilities for how to make new molecular compounds, according to the study co-leaders Klavs F. Jensen, the Warren K. Lewis Professor of Chemical Engineering, and Timothy F. Jamison, the Robert R. Taylor Professor of Chemistry and associate provost at MIT. The technology "has the promise to help people cut out all the tedious parts of molecule building," including looking up potential reaction pathways and building the components of a molecular assembly line each time a new molecule is produced, says Jensen. "And as a chemist, it may give you inspirations for new reactions that you hadn't thought about before," he adds. The new system combines three main steps.

How does artificial intelligence advance Earth system modelling?
How does the Earth system function? The Earth system is incredibly complex, and understanding how it works is important for the survival of our species. Earth system science is an area of knowledge that has advanced rapidly in recent years. So, too, has artificial intelligence. To learn how the latter helps the former, we spoke with Markus Reichstein, who heads the Max Planck Institute's Biogeochemical Integration Department.
Energy Usage Reports: Environmental awareness as part of algorithmic accountability
Lottick, Kadan, Susai, Silvia, Friedler, Sorelle A., Wilson, Jonathan P.
The carbon footprint of algorithms must be measured and transparently reported so computer scientists can take an honest and active role in environmental sustainability. In this paper, we take analyses usually applied at the industrial level and make them accessible for individual computer science researchers with an easy-to-use Python package. Localizing to the energy mixture of the electrical power grid, we make the conversion from energy usage to CO2 emissions, in addition to contextualizing these results with more human-understandable benchmarks such as automobile miles driven. We also include comparisons with energy mixtures employed in electrical grids around the world. We propose including these automatically-generated Energy Usage Reports as part of standard algorithmic accountability practices, and demonstrate the use of these reports as part of model-choice in a machine learning context.
Towards Physics-informed Deep Learning for Turbulent Flow Prediction
Wang, Rui, Kashinath, Karthik, Mustafa, Mustafa, Albert, Adrian, Yu, Rose
While deep learning has shown tremendous success in a wide range of domains, it remains a grand challenge to incorporate physical principles in a systematic manner to the design, training, and inference of such models. In this paper, we aim to predict turbulent flow by learning its highly nonlinear dynamics from spatiotemporal velocity fields of large-scale fluid flow simulations of relevance to turbulence modeling and climate modeling. We adopt a hybrid approach by marrying two well-established turbulent flow simulation techniques with deep learning. Specifically, we introduce trainable spectral filters in a coupled model of Reynolds-averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES), followed by a specialized U-net for prediction. Our approach, which we call turbulent-Flow Net (TF-Net), is grounded in a principled physics model, yet offers the flexibility of learned representations. We compare our model, TF-Net, with state-of-the-art baselines and observe significant reductions in error for predictions60frames ahead. Most importantly, our method predicts physical fields that obey desirable physical characteristics, such as conservation of mass, whilst faithfully emulating the turbulent kinetic energy field and spectrum, which are critical for accurate prediction of turbulent flows.
Bayesian Curiosity for Efficient Exploration in Reinforcement Learning
Blau, Tom, Ott, Lionel, Ramos, Fabio
Balancing exploration and exploitation is a fundamental part of reinforcement learning, yet most state-of-the-art algorithms use a naive exploration protocol like $\epsilon$-greedy. This contributes to the problem of high sample complexity, as the algorithm wastes effort by repeatedly visiting parts of the state space that have already been explored. We introduce a novel method based on Bayesian linear regression and latent space embedding to generate an intrinsic reward signal that encourages the learning agent to seek out unexplored parts of the state space. This method is computationally efficient, simple to implement, and can extend any state-of-the-art reinforcement learning algorithm. We evaluate the method on a range of algorithms and challenging control tasks, on both simulated and physical robots, demonstrating how the proposed method can significantly improve sample complexity.

Time Series Forecasting to Analyze LPG Usage -
The intent of the current study is to analyze the LPG usage consumption and forecasting, by leveraging Time Series, the values to predict the LPG usage โ by giving inputs area-wise, dealer-wise, and season-wise on a weekly, monthly, and yearly basis. This case study leverages AI and Machine Learning to predict LPG usage by using a concept mechanism like a trolley enabled with sensors. These trolleys capture the weights of the cylinders and transmit continuous updates on weight of the cylinder, gas leakage occurrences and ambient temperature to the dealers and manufacturers. Qualetics provides a solution that captures the above-mentioned data points continuously and allows the possibility of real-time streaming analytics of the LPG gas usage as well as advanced analytics on data captured over long periods of time.
