High variance machine learning

WebOct 25, 2024 · Models that have high bias tend to have low variance. For example, linear regression models tend to have high bias (assumes a simple linear relationship between explanatory variables and response variable) and low variance (model estimates won’t change much from one sample to the next). However, models that have low bias tend to … WebJul 6, 2024 · Typically, we can reduce error from bias but might increase error from variance as a result, or vice versa. This trade-off between too simple (high bias) vs. too complex (high variance) is a key concept in statistics and machine learning, and one that affects all supervised learning algorithms.
