Note that winsorizing is not equivalent to simply excluding data, which is a simpler procedure, called trimming or truncation, but is a method of censoring data.. In a trimmed estimator, the extreme values are discarded; in a winsorized estimator, the extreme values are instead replaced by certain percentiles (the trimmed minimum and maximum).
Data cleansing or data cleaning is the process of identifying and correcting (or removing) corrupt, inaccurate, or irrelevant records from a dataset, table, or database.It involves detecting incomplete, incorrect, or inaccurate parts of the data and then replacing, modifying, or deleting the affected data.

By imputing multiple times, multiple imputation accounts for the uncertainty and range of values that the true value could have taken. As expected, the combination of both uncertainty estimation and deep learning for imputation is among the best strategies and has been used to model heterogeneous drug discovery data.
The above formulae show that when < < < + the scale parameter of the truncated normal distribution is allowed to assume negative values. The parameter σ {\displaystyle \sigma } is in this case imaginary, but the function f {\displaystyle f} is nevertheless real, positive, and normalizable.

Typical streams include log files, delimiter-separated values, or email messages, notably for email filtering. For example, an AWK program may take as input a stream of log statements, and for example send all to the console, write ones starting with WARNING to a "WARNING" file, and send an email to a sysadmin in case any line starts with "ERROR".
In both eager and graph executions, TensorFlow provides an API for distributing computation across multiple devices with various distribution strategies. [36] This distributed computing can often speed up the execution of training and evaluating of TensorFlow models and is a common practice in the field of AI.
