Predictive bias definition
WebFeb 15, 2024 · Bias is the difference between our actual and predicted values. Bias is the simple assumptions that our model makes about our data to be able to predict new data. Figure 2: Bias. When the Bias is high, assumptions made by our model are too basic, the model can’t capture the important features of our data. WebInductive bias. The inductive bias (also known as learning bias) of a learning algorithm is the set of assumptions that the learner uses to predict outputs of given inputs that it has not encountered. [1] In machine learning, one aims to construct algorithms that are able to learn to predict a certain target output.
