Automation of machine learning model development is increasingly becoming an established research area. While automated model selection and automated data pre-processing have been studied in depth, there is, however, a gap concerning automated model adaptation strategies when multiple strategies are available. Manually developing an adaptation strategy, including estimation of relevant parameters can be time consuming and costly. In this paper we address this issue by proposing generic adaptation strategies based on approaches from earlier works. Experimental results after using the proposed strategies with three adaptive algorithms on 36 datasets confirm their viability. These strategies often achieve better or comparable performance with custom adaptation strategies and naive methods such as repeatedly using only one adaptive mechanism.

A year later, Barrick has parted ways with its chief innovation officer, chief digital officer and many of the team tasked with making this transformation a reality, according to people familiar with the matter. The revolution in machine learning, as predicted by Barrick Chairman John Thornton and other mining executives, has yet to come. Miners have said digital technologies like artificial intelligence, or AI, will revolutionize one of the world's oldest industries in the same way it has changed other businesses, from retail to hailing a cab. Some experts say the promise of AI in mining has been overhyped and progress has been slow. Companies, including Barrick and giants such as Rio Tinto PLC and BHP Group Ltd., are running some AI-led projects. But implementation at some companies has hit cultural hurdles.

The high-dimensionality and volume of large scale multistream data has inhibited significant research progress in developing an integrated monitoring and diagnostics (M&D) approach. This data, also categorized as big data, is becoming common in manufacturing plants. In this paper, we propose an integrated M\&D approach for large scale streaming data. We developed a novel monitoring method named Adaptive Principal Component monitoring (APC) which adaptively chooses PCs that are most likely to vary due to the change for early detection. Importantly, we integrate a novel diagnostic approach, Principal Component Signal Recovery (PCSR), to enable a streamlined SPC. This diagnostics approach draws inspiration from Compressed Sensing and uses Adaptive Lasso for identifying the sparse change in the process. We theoretically motivate our approaches and do a performance evaluation of our integrated M&D method through simulations and case studies.

We consider the torpedo scheduling problem in steel production, which is concerned with the transport of hot metal from a blast furnace to an oxygen converter. A schedule must satisfy, amongst other considerations, resource capacity constraints along the path and the locations traversed as well as the sulfur level of the hot metal. The goal is first to minimize the number of torpedo cars used during the planning horizon and second to minimize the time spent desulfurizing the hot metal. We propose an exact solution method based on Logic based Benders Decomposition using Mixed-Integer and Constraint Programming, which optimally solves and proves, for the first time, the optimality of all instances from the ACP Challenge 2016 within 10 minutes. In addition, we adapted our method to handle large-scale instances and instances with a more general rail network. This adaptation optimally solved all challenge instances within one minute and was able to solve instances of up to 100,000 hot metal pickups.

A new system combines artificial neural networks with infrared thermal imaging to control and interpret chemical reactions with precision and speed that far outpace conventional methods. Machine learning algorithms can predict stock market fluctuations, control complex manufacturing processes, enable navigation for robots and driverless vehicles, and much more. Now, researchers are tapping a new set of capabilities in this field of artificial intelligence with their new technique. "This system can reduce the decision-making process about certain chemical manufacturing processes from one year to a matter of weeks…" The researchers developed and tested the new method on microreactors that allow chemical discoveries to take place quickly and with far less environmental waste than standard large-scale reactions.

Sensor drift is a well-known issue in the field of sensors and measurement and has plagued the sensor community for many years. In this paper, we propose a sensor drift correction method to deal with the sensor drift problem. Specifically, we propose a discriminative subspace projection approach for sensor drift reduction in electronic noses. The proposed method inherits the merits of the subspace projection method called domain regularized component analysis. Moreover, the proposed method takes the source data label information into consideration, which minimizes the within-class variance of the projected source samples and at the same time maximizes the between-class variance. The label information is exploited to avoid overlapping of samples with different labels in the subspace. Experiments on two sensor drift datasets have shown the effectiveness of the proposed approach. Keywords: Sensor drift; Electronic nose; Subspace projection method; Domain adaptation; Transfer learning.

The vastness of the archival chemistry literature is both a blessing and a curse. The reaction that you're looking for is probably in there, provided you take enough time to search for it. Gao et al. trained a neural network model on 10 million known reactions to speed up this process. Specifically, the model was charged with predicting a catalyst, reagents, solvents, and temperature to achieve a given transformation. When tested, the model's top-10 list of suggestions produced a close match to actual conditions nearly 70% of the time, with a 20 C error margin in temperature.

Vigilante citizens in a town in Arizona have slashed tyres, thrown rocks and even pointed guns at self-driving vehicles being tested in their neighbourhood, an investigation has revealed. Police in Chandler recorded 21 incidents over the past two years in which the autonomous vehicles and their test drivers were targeted by local residents. One incident on 24 October saw a man emerge from a park and slash the tyres of a Waymo vehicle stopped at an intersection. Earlier this year a Waymo test driver reported a man in shorts aiming a gun at his car when it passed the man's driveway. Police reports also show that rocks were thrown at Waymo's fleet on at least four separate occasions, according to The Arizona Republic, while other incidents include people yelling at the vehicles, chasing them and forcing them off the road.

China is just days away from kicking off a historic mission to explore the dark side of the moon. The Chang'e-4, which launches on December 8th, will be the first ever rover to land on the far side of the lunar surface. The spacecraft is slated to leave from the Xichang Satellite Launch Center in Sichuan province, before entering the moon's orbit and hopefully touching down in the massive, 186-kilometer-wide Von Karman crater on the moon's south pole. The Chang'e-4, which launches on December 8th, will be the first ever rover land on the far side of the lunar surface. It will visit an unexplored region of the lunar surfacecalled the South Pole-Aitken Basin, located in the southern hemisphere of the dark side of the moon, which includes the Von Karman crater, among many others.
