It can lead to high sensitivity and overfitting. Variance: Variance is error introduced in your model due to complex machine learning algorithm, your model learns noise also from the training data set and performs badly on test data set. Low bias machine learning algorithms - Decision Trees, k-NN and SVM High bias machine learning algorithms - Linear Regression, Logistic Regression When you train your model at that time model makes simplified assumptions to make the target function easier to understand.

Time interval: A trial may be terminated early at an extreme value (often for ethical reasons), but the extreme value is likely to be reached by the variable with the largest variance, even if all variables have a similar mean.Дata: When specific subsets of data are chosen to support a conclusion or rejection of bad data on arbitrary grounds, instead of according to previously stated or generally agreed criteria.ДЄttrition:В Attrition bias is a kind of selection bias caused by attrition (loss of participants) discounting trial subjects/tests that did not runВ to completion.Д«ias: Bias is an error introduced in your model due to oversimplification of the machine learning algorithm. Sampling bias: It is a systematic error due to a non-random sample of a population causing some members of the population to be less likely to be included than others resulting in a biased sample. If the selection bias is not taken into account, then some conclusions of the study may not be accurate. It is the distortion of statistical analysis, resulting from the method of collecting samples. It is usually associated with research where the selection of participants isnвЂ™t random.В It is sometimes referred to as the selection effect. Selection bias is a kind of error that occurs when the researcher decides who is going to be studied. The differences between supervised and unsupervised learning are as follows Д®nables Classification, Density Estimation, & Dimension Reduction The answer lies in the difference between explaining and predicting. How is this different from what statisticians have been doing for years?

What is Data Science? List the differences between supervised and unsupervised learning.Дata Science is a blend of various tools, algorithms, and machine learning principles with the goal to discover hidden patterns from the raw data.
