Feb 15, 2022 · Bias-Variance Tradeoff. For any model, we have to find the perfect balance between Bias and Variance. This just ensures that we capture the essential patterns in our model while ignoring the noise present it in. This is called Bias-Variance Tradeoff. It helps optimize the error in our model and keeps it as low as possible.

Suppose that we have a training set consisting of a set of points and real values associated with each point . We assume that there is a function with noise , where the noise, , has zero mean and variance . We want to find a function , that approximates the true function as well as possible, by means of some learning algorithm based on a training dataset (sample) . We make "as well as possible" p…

What Is the Difference Between Bias and Variance?
https://www.mastersindatascience.org/learning/difference-between-bias-and-variance/
Machine learning algorithms use mathematical or statistical models with inherent errors in two categories: reducible and irreducible error. Irreducible error, or inherent uncertainty, is due to natural variability within a system. In comparison, reducible error is more controllable and should be minimized to ensure higher accuracy. Bias and varianc...

The bias-variance decomposition shows that there is no other aspect of $T$ that contributes to the mean square error. The MSE, bias, and variance of $T$ all depend on $\theta$. We typically don't know the parameter $\theta$, so we can't compute numerical values of these quantities.

Introducing Model Bias and Variance | by Peter Grant

Jul 19, 2019 · Bias refers to constant error at all points, representing a model that isn’t complex enough to capture the data set. Variance refers to a model that is too complex for the data set, often acting as if there are trends in the data set that don’t really exist. These two types of error lead to the famous Bias-Variance Trade-Off.
