This Python quickstart demonstrates a linear regression model on a local Machine Learning Server, using functions from the revoscalepy library and built-in sample data. Steps are executed on a Python command line using Machine Learning Server in the default local compute context. In this ...
We’ll attempt the following using Python and PyTorch: Creating synthetic data where we’re aware of weights and bias Using the PyTorch framework and built-in functions for tensor operations, dataset loading, model definition, and training We don’t need a validation set for this example since...
return1.0 / (1 + exp(-inX)) # train a logistic regression model using some optional optimize algorithm # input: train_x is a mat datatype, each row stands for one sample # train_y is mat datatype too, each row is the corresponding label # opts is optimize option include step and m...
In this recipe, we'll look at how well our regression fits the underlying data. We fit a regression in the last recipe, but didn't pay much attention to how well we actually did it. The first question after we fit the model was clearly "How well does the model fit?" In this recip...

classification rather than regression. Logistic regression is also known in the literature as logit regression, maximum-entropy classification (MaxEnt) or the log-linear classifier. In this model, the probabilities describing the possible outcomes of a single trial are modeled using a logistic function...
To run that regression model in Python, you can use statsmodels’ formula API. It allows you to express linear models succinctly, using R-style formulas. For example, you can represent the preceding model with the formula 'watch_time ~ C(recommender)'. To estimate the model, just call the...
