WebThe previous example suggests that there can be more than one sufficient statistic for a parameter θ. In general, if Y is a sufficient statistic for a parameter θ, then every one-to-one function of Y not involving θ is also a sufficient statistic for θ. Let's take a look at another example.

Examples of hyperparameters in logistic regression Learning rate (α). One way of training a logistic regression model is with gradient descent. danteh overwatch ageWebThe actual step of θ is defined by the function parameter, so if you use the usual math.pi / 180.0 value of theta, the algorithm will compute ρ 180 times in total for just one edge pixel in the image. If you would use a larger theta, there would be fewer calculations, fewer accumulator columns/buckets and therefore fewer lines found. birthday scrapbook ideas for adults
