There’s a lot going on in the above code block, so here’s a line-by-line breakdown: Line 8 picks a random instance from the dataset. Lines 14 to 16 calculate the partial derivatives and return the derivatives for the bias and the weights. They use _compute_gradients(), which you ...
While we can use frequencies to calculate probabilities of occurrence for categorical attributes, we cannot use the same approach for continuous attributes. Instead, we first need to calculate the mean and variance for x in each class and then calculate P(x|C) using the following formula: Be...

1 Accuracy: 0.797 (0.073) Next, let’s explore a scaling transform of the dataset. MinMaxScaler Transform We can apply the MinMaxScaler to the Sonar dataset directly to normalize the input variables. We will use the default configuration and scale values to the range 0 and 1. First, a Min...
with a larger dataset (like the LISA Dataset) to fully realize YOLO’s capabilities, we use a small dataset in this tutorial to facilitate quick prototyping. Typical training takes less than half an hour, which would allow you to iterate quickly with experiments involving different hyperparameters...

you should use decimals in your code when you need to represent fractional values or perform calculations that require a high degree of precision. for example, if you're coding a program to calculate the average score of a game, using decimals would make sense as the result could be a ...
