'platypus' is an R package that allows you to build advanced deep learning models like YOLO3 and U-Net for object detection and image segmentation tasks. Thanks to build in data generators and ready to go architectures you can implement perfect solution with a few lines of code. # Biogram I’m a data scientist with over 5 years of experience in the field, R/Shiny developer and a freelancer interested in deep/machine learning and statistics.

  • Gradient Boosting Machines - From Zero to Hero - X-Europe Webinars

    Gradient Boosting Machines (GBM): from Zero to Hero (with R and Python code) REGISTER HERE: https://gradient-boosting-zero-to-hero.carrd.co/ This talk will get you started with gradient boosting machines (GBM), a very popular machine learning technique providing state-of-the-art accuracy on numerous business prediction problems. After a quick intro to machine learning and the GBM algorithm, I will show how easy it is to train and then use GBMs in real-life business applications using some the most popular open source implementations (xgboost, lightgbm and h2o). We’ll do all this in both R and Python with only a few lines of code and this talk will be accessible for a wide audience (with limited prior knowledge of machine learning). Finally, in the last part of the talk I will provide plenty of references that can get you to the next level. GBMs are a powerful technique to have in your machine learning toolbox, because despite all the latest hype about deep learning (neural nets) and “AI”, in fact GBMs usually outperform neural networks on structured/tabular data most often encountered in business applications. OUR SPEAKER Szilard Pafka, PhD Chief Scientist, Epoch (USA) Szilard studied Physics in the 90s and obtained a PhD by using statistical methods to analyze the risk of financial portfolios. He worked in finance, then more than a decade ago moved to become the Chief Scientist of a tech company in Santa Monica, California doing everything data (analysis, modeling, data visualization, machine learning, data infrastructure etc). He is the founder/organizer of several meetups in the Los Angeles area (R, data science etc) and the data science community website datascience.la. He is the author of a well-known machine learning benchmark on github (1000+ stars), a frequent speaker at conferences (keynote/invited at KDD, R-finance, Crunch, eRum and contributed at useR!, PAW, EARL, H2O World, Data Science Pop-up, Dataworks Summit etc.), and he has developed and taught graduate data science and machine learning courses as a visiting professor at two universities (UCLA in California and CEU in Europe).

  • The strong ML hypothesis by Antonio Piccolboni

    Online event

    Date:[masked]pm UTC+2 Title: The strong ML hypothesis Registration: https://ml-hypothesis.carrd.co/ SPEAKER: Antonio Piccolboni https://piccolboni.info/ TALK: The strong machine learning hypothesis can be roughly stated as: "test set generalization is all that matters" with the corollary that "scaling is all we need". These ideas are propelling much of the recent work and excitement in machine learning. I will list four reasons why the hypothesis is not likely to be true and two why scaling is not promising even if the hypothesis were true. SPEAKER: Antonio Piccolboni is a Data Scientist with 30+ years of experience, including a decade in bioinformatics. He started working on neural networks as a student during the second "AI winter" and has been a keen observer and at times a user of the technology ever since. His main claim to fame is the most widely adopted R package for Hadoop, rmr2, which has been downloaded more than 1M times. He recently switched his focus to the climate crisis.

  • Can Telematics Data Identify Risky Drivers?

    Needs a location

    Register - https://telematics-data.carrd.co/ This is a joint online event of Vienna Data Science Group, Frankfurt Data Science, Budapest Data Science Meetup, BCN Analytics, Budapest.AI, Barcelona Data Science and Machine Learning Meetup, Budapest Deep Learning Reading Seminar and Warsaw R Users Group. TALK Many insurance companies collect telematics data about drivers’ exposure to traffic (distance driven and type of road) and their driving behavior (excess speed, aggressiveness, operating hours). Actuaries, who are experts in risk analysis for insurers, use this information to improve the insurance rate-making process. Personalized driving risk indicators can also promote driving safety. The starting point is data collected from inertial measurement units installed in vehicles, combined with the corresponding records of accidents. We will address the most relevant current challenges in driving risk measurement. Illustrations with several real data sets provided by insurance companies will answer questions: How should pay-per-mile insurance schemes be designed? How can near-miss telematics be used to identify risky drivers? What is the power of risk analytics, percentile charts, and reference curves to monitor drivers? We will emphasize the enormous potential of this field to design better insurance products and improve safety. We will perhaps be able to guess why Tesla is urgently looking for actuaries in the last few weeks. SPEAKER Montserrat Guillen has a Ph.D. in Economics, MSc in Mathematical Statistics, and MA in Data Analysis. Professor at the University of Barcelona & Director of Riskcenter – Research Group on Risk in Insurance and Finance. Montserrat is a specialist in Actuarial Science and Insurance. Top-ten cited author (ResearchGate). Optimistic likes understanding data and mitigating risks. Loves having friends from around the world.
