WitrynaThis tutorial introduces logistic regression using Theano and stochastic gradient descent. Logistic regression is a probabilistic, linear classifier. It is parametrized by a weight matrix :math:`W` and a bias vector :math:`b`. Classification is done by projecting data points onto a set of hyperplanes, the distance to Witryna1 kwi 2024 · Using this output, we can write the equation for the fitted regression model: y = 70.48 + 5.79x1 – 1.16x2. We can also see that the R2 value of the model is 76.67. This means that 76.67% of the variation in the response variable can be explained by the two predictor variables in the model. Although this output is useful, we still don’t know ...
