The synthetic data set was generated from a previously published theoretical model by Fuchs et al. 2005 that we modified. Once trained, these machine-learning methods can assist with efforts to maximize the peak proton energy, or with the more general problem of configuring the laser system to produce a proton energy spectrum with desired characteristics. In our study, we focus on both the accuracy of the machine-learning methods and the performance on one GPU including memory consumption. Although it is arguably the least sophisticated machine-learning model we considered, support vector regression performed very well in our tests.  \n1 | Introduction  \nThe field of ultra-intense laser science is increasingly beginning to embrace machine learning (ML) and Bayesian optimization methods [1, 2] . This is especially true as the repetition rates of ultra-intense laser systems increase and data acquisition systems improve (e.g., Heuer et","cbCaikuScLSkzELx","https://ap.wps.com/l/cbCaikuScLSkzELx","pdf",1492509,1,13,"English","en",105,"# Introduction\n## Machine learning for ultra-intense laser proton acceleration\n## Background and related work","[{\"question\":\"Which machine-learning methods are compared in the study?\",\"answer\":\"The study compares a three-hidden-layer neural network, support vector regression, and Gaussian process regression.\"},{\"question\":\"What data are used to train the models?\",\"answer\":\"Models are trained using a synthetic dataset generated from a previously published theoretical model, which is modified by the authors.\"},{\"question\":\"What evaluation aspects are emphasized beyond learning performance?\",\"answer\":\"The paper evaluates both accuracy and computational performance on one GPU, including memory consumption.\"}]","Applying Machine-Learning Methods to Laser Acceleration of Protons - Lessons Learned From Synthetic Data | PDF",1785683305,33,{"code":4,"msg":31,"data":32},"ok",{"site_id":24,"language":23,"slug":33,"title":13,"keywords":34,"description":14,"schema_data":35,"social_meta":86,"head_meta":88,"extra_data":90,"updated_unix":28},"applying-machine-learning-methods-to-laser-acceleration-of-protons-lessons-learned-from-synthetic-data","",{"@graph":36,"@context":85},[37,54,68],{"@type":38,"itemListElement":39},"BreadcrumbList",[40,44,48,51],{"item":41,"name":42,"@type":43,"position":20},"https://docshare.wps.com","Home","ListItem",{"item":45,"name":46,"@type":43,"position":47},"https://docshare.wps.com/document/","Document",2,{"item":49,"name":12,"@type":43,"position":50},"https://docshare.wps.com/document/research-report/",3,{"item":52,"name":13,"@type":43,"position":53},"https://docshare.wps.com/document/applying-machine-learning-methods-to-laser-acceleration-of-protons-lessons-learned-from-synthetic-data/118369/",4,{"url":52,"name":13,"@type":55,"author":56,"headline":13,"publisher":58,"fileFormat":61,"inLanguage":23,"description":14,"dateModified":62,"datePublished":62,"encodingFormat":61,"isAccessibleForFree":63,"interactionStatistic":64},"DigitalDocument",{"name":9,"@type":57},"Person",{"url":41,"name":59,"@type":60},"DocShare","Organization","application/pdf","2026-08-02",true,{"@type":65,"interactionType":66,"userInteractionCount":4},"InteractionCounter",{"@type":67},"ViewAction",{"@type":69,"mainEntity":70},"FAQPage",[71,77,81],{"name":72,"@type":73,"acceptedAnswer":74},"Which machine-learning methods are compared in the study?","Question",{"text":75,"@type":76},"The study compares a three-hidden-layer neural network, support vector regression, and Gaussian process regression.","Answer",{"name":78,"@type":73,"acceptedAnswer":79},"What data are used to train the models?",{"text":80,"@type":76},"Models are trained using a synthetic dataset generated from a previously published theoretical model, which is modified by the authors.",{"name":82,"@type":73,"acceptedAnswer":83},"What evaluation aspects are emphasized beyond learning performance?",{"text":84,"@type":76},"The paper evaluates both accuracy and computational performance on one GPU, including memory consumption.","https://schema.org",{"og:url":52,"og:type":87,"og:title":13,"og:site_name":59,"og:description":14},"article",{"robots":89,"canonical":52},"index,follow",{"doc_id":7,"site_id":24},{"code":4,"msg":5,"data":92},[93,97,101,105,110,115,120,123,128,131,135],{"id":20,"doc_module":4,"doc_module_name":46,"category_name":94,"show_sort_weight":95,"slug":96},"Story & Novel",90,"story-novel",{"id":47,"doc_module":4,"doc_module_name":46,"category_name":98,"show_sort_weight":99,"slug":100},"Literature",80,"literature",{"id":53,"doc_module":4,"doc_module_name":46,"category_name":102,"show_sort_weight":103,"slug":104},"Exam",70,"exam",{"id":106,"doc_module":4,"doc_module_name":46,"category_name":107,"show_sort_weight":108,"slug":109},5,"Comic",60,"comic",{"id":111,"doc_module":4,"doc_module_name":46,"category_name":112,"show_sort_weight":113,"slug":114},6,"Technology",50,"technology",{"id":116,"doc_module":4,"doc_module_name":46,"category_name":117,"show_sort_weight":118,"slug":119},7,"Healthcare",40,"healthcare",{"id":11,"doc_module":4,"doc_module_name":46,"category_name":12,"show_sort_weight":121,"slug":122},30,"research-report",{"id":124,"doc_module":4,"doc_module_name":46,"category_name":125,"show_sort_weight":126,"slug":127},9,"Religion & Spirituality",20,"religion-spirituality",{"id":126,"doc_module":4,"doc_module_name":46,"category_name":129,"show_sort_weight":126,"slug":130},"World Cup","world-cup",{"id":132,"doc_module":4,"doc_module_name":46,"category_name":133,"show_sort_weight":132,"slug":134},10,"Lifestyle","lifestyle",{"id":136,"doc_module":4,"doc_module_name":46,"category_name":137,"show_sort_weight":106,"slug":138},19,"General","general"]
