Jupyter Notebooks, formerly known as IPython Notebooks, are ubiquitous in modern data analysis. The Vision AI Developer Kit, a Qualcomm IoT camera coupled with an Azure toolkit for AI vision applications, is now generally available. In this talk, I'll describe how data scientists can transition their existing workflows — while using mostly the same tools and processes — to train and deploy machine learning models based on open source frameworks to Azure. Learn how to use Azure Machine Learning to solve business problems. Glancing at the source (available from your link), it appears that LGBMModel is the parent class for LGBMClassifier (and Ranker and Regressor). XGBoost and LightGBM packages implement gradient-boosted decision trees in a very efficient and optimized way. For example, exporting a logistic regression model produces a directory containing the following JSON files: metadata, which contains the type of the model and how it was configured for training. This project solves the parallelization problem of this algorithm. Hi I am unable to find an way to save and reuse an LGBM model to a file. lightgbm » lightgbmlib » 2.
