A computational intelligence approach to predict energy demand using Random Forest in a Cloudera cluster

<p>Society&rsquo;s energy consumption has shot up in recent years, making the prediction of&nbsp;its demand a current challenge to ensure an efficient and responsible use. Artificial intelligence&nbsp;techniques have proven to be potential tools in handling tedious tasks and making sense of&nbsp;large-scale data to make better business decisions in different areas of knowledge. In this article,&nbsp;the use of random forests algorithms in a Big Data environment is proposed for households energy&nbsp;demand forecasting. The predictions are based on the use of information from different sources,&nbsp;confirming a fundamental role of socioeconomic data in consumer&rsquo;s behaviours. On the other&nbsp;hand, the use of Big Data architectures is proposed to perform horizontal and vertical scaling of&nbsp;the solution to be used in real environments. Finally, a tool for high-resolution predictions with&nbsp;great efficiency is introduced, which enables energy management in a very accurate way.</p> <p>Raw data is incuded in data.csv. This file contains half hourly home electricity consumption registers for 4404&nbsp;households with fix tariffs (not subject to dynamic time of use) for a period between November 2011 and February 2014. Original information was acquired from the Low Carbon London project led by UK Power Networks (https://data.london.gov.uk/dataset/smartmeter-energy-use-data-in-london-households)</p> <p>RFResults.zip contains the energy predictions for each ACORN group using the generated Random Forest algorithm. For this purpose, the first 613 days of a total of 818 observations of each group were considered for training and the last 205 days for testing.</p> <p>Meteorological data was adquired from the darksky app (https://darksky.net).&nbsp;These data are included in the weather_hourly_darksky.csv</p> <p>uk_bank_holidays. xlsx contains the dated of UK bank holidays for the studied period, used as additional variable related to occupancy</p>

Global gross primary production (GPP) product generated by data fusion based on random forest

<p>Improving the ability of gross primary production (GPP) estimates to capture extreme climate perturbations and reduce the uncertainty of GPP response processes to extreme climate is a new challenge. Based on the random forest algorithm, we integrated the multimodel GPP simulation results published by the Multiscale Synthesis and Terrestrial Model Intercomparison Project, the FLUXNET flux-site-observed GPP, the standardized precipitation index (SPI) and the standardized temperature index (STI) to generate a set of global GPP time-series data products from 2001 to 2010. The new GPP product was named DFRF-GPP, referring to the GPP generated by data fusion based on random forest. DFRF-GPP is highly reliable and can be used as a valuable data source for various applications, especially in high-temperature and drought-related studies.</p>

3D S-wave velocity profiles with random fields

<p>This dataset contains 100,000 3D matrices representing S-wave velocity profiles with random fields. The spatial resolution corresponds to a grid of 9.6 x 9.6 x 9.6km with a spatial step of 300m (matrices are of size 33 x 33 x 33). Velocities go from 1,071 to 4,500m/s.</p> <p>Each profile contains a 1.8km-thick bottom layer at constant velocity 4500m/s. Above, the profile contains between 1 and 6 layers of random thickness. In each layer, the mean velocity is chosen uniformly in [1,785; 3,214m/s] and the coefficient of variation follows a Gaussian distribution N(0.2; 0.1). Then, a correlation length is chosen randomly among 1.5, 3, 4.5, 6 km in all three directions for each layer.</p> <p>The random fields&#39; kernel has a von Karman correlation with a Hurst exponent of 0.1 and log-normal marginal distributions.</p>

Raw and post-processed data for the microscopic investigation of the effect of random envelope fluctuations on phoneme-in-noise perception

<p>The current dataset consists of three main folders:</p> <ul> <li><strong>01-Stimuli/</strong>: Contains the three sets of noises (white noise, bump noise, MPS noise) for the 12 study participants (S01 to S12).</li> <li><strong>02-Raw-data/fastACI/</strong>: Contains the raw data as obtained for each participant, which are also available within the GitHub repository of the fastACI toolbox, using the same directory tree. The results for each (anonymised) participant (under: <strong>publ_osses2022b/data_SXX/1-experimental_results/</strong>) include their audiometric thresholds (folder: <strong>audiometry</strong>), the results for the Intellitest speech test (folder: <strong>intellitest</strong>), and for the phoneme-in-noise test /aba/-/ada/ for the three noises (savegame files in MAT format).</li> <li><strong>02-Raw-data/ACI_sim/</strong>: Contains the raw data as obtained for the artificial listener, i.e., the model osses2022a.m (available within the fastACI toolbox). Twelve sets of simulations (using the waveforms of participants S01 to S12) were run for the three types of test noises. The results of the simulations of the phoneme-in-noise test are stored in the savegame MAT files. The template derived from 100 repetitions of /aba/ and /aba/ at an SNR=-6 dB in white noise is also included (template-osses2022a-speechACI_Logatome-abda-S43M-trial-1-v1-white-2022-7-15-N-0100.mat). The same template was used in all simulations.</li> <li><strong>03-Post-proc-data/ACI_exp/</strong>: Auditory classification images (ACIs) derived from the participants&#39; data (folder: <strong>ACI_exp</strong>) and from the simulations (folder: <strong>ACI_sim</strong>). For each participant (or artificial listener) there are three ACIs (MAT files) for each of the corresponding noises. Cross predictions are also included with performance predictions across &#39;participants&#39; (Crosspred.mat, 12 cross predictions for each noise) or across &#39;noises&#39; (Crosspred-noise.mat, 3 cross predictions for each participant).

Data of the publication "Transport and entanglement growth in long-range random Clifford circuits"

<p>Conservation laws can constrain entanglement dynamics in isolated quantum systems, manifest in a slowdown of higher R&eacute;nyi entropies. Here, we explore this phenomenon in a class of long-range random Clifford circuits with U(1) symmetry where transport can be tuned from diffusive to superdiffusive. We unveil that the different<br> hydrodynamic regimes reflect themselves in the asymptotic entanglement growth according to&nbsp;<span class="math-tex">\(S(t) \propto t^{1/z}\)</span> where<br> the dynamical transport exponent z depends on the probability&nbsp;<span class="math-tex">\(\propto r^{-\alpha}\)</span> of gates spanning a distance r. For<br> sufficiently small <span class="math-tex">\(\alpha\)</span>, we show that the presence of hydrodynamic modes becomes irrelevant such that S(t) behaves<br> similarly in circuits with and without conservation law. We explain our findings in terms of the inhibited operator<br> spreading in U(1)-symmetric Clifford circuits where the emerging light cones can be understood in the context<br> of classical L&eacute;vy flights. Our Letter sheds light on the connections between Clifford circuits and more generic<br> many-body quantum dynamics.</p>

Geographic Scope of Randomized Clinical Trials from Africa

<p><strong>Overview</strong></p> <p>This map reports the geographic scope of randomized controlled trials (RCTs) conducted in Africa, as found in PubMed. The map highlights a discrepancy between actual trial location and how trials are reported: although reports of research from Africa are often labeled as being "African" in scope, RCTs are rarely continent-wide and many countries are not represented in even a single study. The intent of the map is to visualize actual trial locations, hopefully leading to a more accurate portrayal of RCT study sites on the African continent.</p> <p><strong>Data Source and Tools</strong></p> <p>Data for the map was extracted from PubMed and the map was created in ArcGIS Online.</p> <p><strong>Audience</strong></p> <p>The map was created for an original research poster at the 2022 International Congress on Peer Review and Scientific Publication (see "Attribution" below). Its audience is researchers, clinicians, policy makers, librarians, scholarly communications stakeholders, and editors in chief interested in improving the accuracy of the reported scope of research in Africa to better inform health care research, policy, and resource distribution.</p> <p><strong>Design</strong></p> <p>A PubMed search using Medical Subject Headings and keywords representing Africa, African, and RCTs was run to identify citations published between 1968 and February 2022. The citation titles and abstracts were screened against established inclusion/exclusion criteria, with included studies continuing through a full text review and data extraction process. Total RCT representation per country was then mapped in ArcGIS with higher RCT counts represented by darker shading. The map highlights the variance in RCT representation across the continent, with some countries represented in up to 80 RCTs and many countries represented in none.</p> <p><strong>Attribution</strong></p> <p>Folafoluwa Olutobi Odetola and Marisa L.

EXTREMA: Random autonomous interplanetary mission scenarios for EXTREMA Simulation Hub (ESH) hardware-in-the-loop simulations

<p>EXTREMA (short for Engineering Extremely Rare Events in Astrodynamics for Deep-Space Missions in Autonomy) enables self-driving spacecraft, challenging the current paradigm under which spacecraft are piloted in the interplanetary space [1]. Deep-space guidance, navigation, and control applied in a complex scenario is the subject of EXTREMA, which wants to engineer ballistic capture in a totally autonomous fashion. EXTREMA is erected on three pillars. Pillar 1 is on autonomous navigation. Pillar 2 involves autonomous guidance and control. Pillar 3 deals with autonomous ballistic capture.&nbsp;The outcomes from each one of the three pillars is validated with a tailored experiment featuring the model of the associated CubeSat subsystems. Integrated experiments involving all the components of a CubeSat GNC system are carried on in the EXTREMA Simulation Hub, an integrated facility simulating&nbsp;an interplanetary&nbsp;transfer with a hardware-in-the-loop setup. The project has been awarded a European Research Council (ERC) Consolidator Grant in 2019.</p> <p>The data set is made of 1000 (even more in some releases) random interplanetary mission scenarios used for hardware-in-the-loop simulations performed in the EXTREMA simulation Hub (ESH). Each scenario comes with the following information: generation seed, initial epoch, initial state (Keplerian elements and Cartesian coordinates), initial attitude (quaternion and direct cosine matrix),&nbsp;initial mass, number of revolution, time of flight, target final epoch, target final state (Keplerian elements and Cartesian Coordinates), and other supplementary data. Scenarios are organized in directories each containing at least the following files:</p> <ul> <li>&#39;esh_ic.json&#39;: random scenario information saved in&nbsp;.json format;</li> <li>&#39;esh_ic.mat&#39;: random scenario information saved in .mat format.</li> </ul> <p>Some releases provide only a limited set of data in the &#39;esh_ic.json&#39; file. For those, the full set of information is found in the &#39;esh_ic_full.json&#39; file.</p> <p>For additional information about the EXTREMA project visit the page&nbsp;<a href="http://extrema.polimi.it/">extrema.polimi.it</a>.</p> <p><strong>References</strong><br> [1]&nbsp;Di Domenico&nbsp;G., et al. &quot;The ERC-Funded EXTREMA Project: Achieving Self-Driving Interplanetary CubeSats.&quot;&nbsp;<em>Modeling and Optimization in Space Engineering: New Concepts and Approaches</em>.
