In statistics, the bias (or bias function) of an estimator (here, the machine learning model) is the difference between the estimator’s expected value and the true value for a given input. An estimator or a decision rule with zero bias is called unbiased. High bias of a machine learning model is a condition where the output … Ver mais In this post, we’ll be going through: (i) The methods to evaluate a machine learning model’s performance (ii) The problem of underfitting and overfitting (iii) The Bias-Variance Trade-off … Ver mais Before directly going into the problems that occur in machine learning models, how do we know that there is an issue with our model? For this, … Ver mais The Bias-Variance tradeoff is a property that lies at the heart of supervised machine learning algorithms. Ideally, we want a machine learning model which takes into account all the patterns as well as the outliers in the … Ver mais The terms bias and variance must not sound new to the readers who are familiar with statistics.
