    Emory University Reports Findings in Machine Learning [D-Mach ine Learning to Elevate DFT-Based Potentials and a Force Field to the CCSD(T) Le vel Illustrated for Ethanol]

    105-105页
    查看更多>>摘要：By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – New research on Machine Learning is th e subject of a report. According to news originating from Atlanta, Georgia, by N ewsRx correspondents, research stated, “Progress in machine learning has facilit ated the development of potentials that offer both the accuracy of first-princip les techniques and vast increases in the speed of evaluation. Recently, D-machin e learning has been used to elevate the quality of a potential energy surface (P ES) based on low-level, e.g., density functional theory (DFT) energies and gradi ents to close to the gold-standard coupled cluster level of accuracy.” Our news journalists obtained a quote from the research from Emory University, “ We have demonstrated the success of this approach for molecules, ranging in size from HO to 15-atom acetyl-acetone and tropolone. These were all done using the B3LYP functional. Here, we investigate the generality of this approach for the P BE, M06, M06-2X, and PBE0 + MBD functionals, using ethanol as the example molecu le. Linear regression with permutationally invariant polynomials is used to fit both low-level and correction PESs. These PESs are employed for standard RMSE an alysis for training and test data sets, and then general fidelity tests such as energetics of stationary points, normal-mode frequencies, and torsional potentia ls are examined. We achieve similar improvements in all cases. Interestingly, we obtained significant improvement over DFT gradients where coupled cluster gradi ents were not used to correct the low-level PES.”

    Data from Colorado State University Advance Knowledge in Machine Learning (Retri eval of boundary layer precipitable water from GOES ABI using machine learning t echniques)

    107-107页
    查看更多>>摘要：By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – Researchers detail new data in artific ial intelligence. According to news originating from Fort Collins, Colorado, by NewsRx correspondents, research stated, “Low-level moisture is an important ingr edient for forecasting severe storms, especially over the Great Plains where sev ere storms often develop along the dryline.” Our news journalists obtained a quote from the research from Colorado State Univ ersity: “Although ground-based observation systems such as lidar or radiosondes on weather balloons provide accurate information on low-level moisture, data are provided at limited locations, and the low temporal resolution of radiosondes m akes it difficult to track a rapidly developing dryline. Geostationary satellite s provide high spatial and temporal observation, but the channels of current geo stationary satellites are mostly sensitive to water vapor at mid to upper levels . However, the split window difference (SWD) between the “clean” window channel (10.3 mm) and the “dirty” window channel (12.3 mm) is commonly used for estimati ng low-level water vapor. However, this estimation is complicated by surface tem perature contributions, dependence on the lapse rate, and nonlinear relationship s between SWD and moisture. This study applies machine learning techniques to in fer boundary layer precipitable water (BLPW) from Geostationary Operational Envi ronmental Satellite (GOES) Advanced Baseline Imager (ABI) data. Since there are few observations that cover wide regions for training convolutional neural netwo rks, especially for the atmosphere above the surface, High-Resolution Rapid Refr esh (HRRR) model outputs are used as the truth for training.”

    Researchers from University of the Free State Report Recent Findings in Machine Learning (Effectiveness of Lof, Iforest and Ocsvm In Detecting Anomalies In Stre am Sediment Geochemical Data)

    110-111页
    查看更多>>摘要：By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – Investigators discuss new findings in Machine Learning. According to news originating from Bloemfontein, South Africa, by NewsRx correspondents, research stated, “This paper compares three unsupervi sed machine-learning algorithms - local outlier factor (LOF), Isolation Forest ( iForest) and oneclass support vector machine (OCSVM) - for anomaly detection in a multivariate geochemical dataset in northeastern Iran. This area contains sev eral Au, Cu and Pb-Zn mineral occurrences.” Our news journalists obtained a quote from the research from the University of t he Free State, “The methodology incorporates single-element geochemistry, multiv ariate data analysis and application of the three unsupervised machine-learning algorithms. Principal component analysis unveiled diverse elemental associations for the first seven principal components (PCs): PC1 shows a Co-Cr-Ni-V-Sn assoc iation indicating a lithological influence; PC2 shows a Au-Bi-Cu-W association s uggesting epithermal Au mineralization; PC3 shows variability in Zn-V-Co-Sb-Cu-C r; PC4 shows a Au-Cu-Ba-Sr-Ag association indicating Au and polymetallic mineral ization; PC5 reflects Zn-Ag-Ni-Pb related to hydrothermal mineralization; and PC 6 and PC7 show element associations suggesting epithermal and intrusive-related polymetallic mineralization. It was found that OCSVM performed slightly better t han LOF and iForest in detecting anomalies associated with known Cu occurrences, and it successfully delineated dispersion from all known Au occurrences. LOF ou tperformed iForest and OCSVM in identifying all four Pb-Zn occurrences, and the three methods substantially limited the areas of the anomaly class. The analysis showed that LOF produced a less cluttered anomaly map compared to the isolated patterns in the iForest map. LOF was accurate in identifying anomalies associate d with Au-Pb mineralization, while iForest detected anomalies associated with Pb -Zn-Cu occurrences and neighbouring Pb-Zn occurrence. OCSVM performed similarly in the northern and western areas but displayed unique discrepancies in the SE a nd west by detecting anomalies associated with two Cu occurences and a Pb-Cu occ urrence. This study examined the influence of contamination fraction on detectio n of geochemical anomalies, revealing a noteworthy rise in the count of mineral occurrences delineated by anomalies when the contamination fraction increases fr om 5 to 10 %.”

    Data on Artificial Intelligence Reported by Luca Massimino and Colleagues (Artif icial intelligence: A new tool in the pathologist’s armamentarium for the diagno sis of IBD)

    111-112页
    查看更多>>摘要：By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – New research on Artificial Intelligenc e is the subject of a report. According to news originating from Milan, Italy, b y NewsRx correspondents, research stated, “Inflammatory bowel diseases (IBD) are classified into two entities, namely Crohn’s disease (CD) and ulcerative coliti s (UC), which differ in disease trajectories, genetics, epidemiological, clinica l, endoscopic, and histopathological aspects. As no single golden standard modal ity for diagnosing IBD exists, the differential diagnosis among UC, CD, and non- IBD involves a multidisciplinary approach, considering professional groups that include gastroenterologists, endoscopists, radiologists, and pathologists.” Our news journalists obtained a quote from the research, “In this context, histo logical examination of endoscopic or surgical specimens plays a fundamental role . Nevertheless, in differentiating IBD from non-IBD colitis, the histopathologic al evaluation of the morphological lesions is limited by sampling and subjective human judgment, leading to potential diagnostic discrepancies. To overcome thes e limitations,artificial intelligence (AI) techniques are emerging to enable au tomated analysis of medical images with advantages in accuracy, precision, and s peed of investigation, increasing interest in the histological analysis of gastr ointestinal inflammation.”

Accordi ng to news reporting originating in Uttarakhand, India, by NewsRx journalists, r esearch stated, “This work investigates the use of a fuzzy logic controller (FLC ) for two-wheeled differential drive mobile robot trajectory tracking control. D ue to the inherent complexity associated with tuning the membership functions of an FLC, this work employs a particle swarm optimization algorithm to optimize t he parameters of these functions.” The news reporters obtained a quote from the research from the Indian Institute of Technology Roorkee, “In order to automate and reduce the number of rule bases , the genetic algorithm is also employed for this study. The effectiveness of th e proposed approach is validated through MATLAB simulations involving diverse pa th tracking scenarios. The performance of the FLC is compared against establishe d controllers, including minimum norm solution, closed-loop inverse kinematics, and Jacobian transpose-based controllers. The results demonstrate that the FLC o ffers accurate trajectory tracking with reduced root mean square error and contr oller effort. An experimental, hardware-based investigation is also performed fo r further verification of the proposed system. In addition, the simulation is co nducted for various paths in the presence of noise in order to assess the propos ed controller’s robustness.”
