Preprocessing image data to ensure that it is in a format that the network can accept is a common first step in deep learning workflows. For example, you can resize image input to match the size of an image input layer. You can also preprocess data to enhance desired features or reduce ...
Data preprocessing, a component ofdata preparation, describes any type of processing performed onraw datato prepare it for anotherdata processingprocedure. It has traditionally been an important preliminary step for thedata miningprocess. More recently, data preprocessing techniques have been adapted for ...

One of the main purposes of data preparation is to ensure that raw data being processed for analytics uses is accurate and consistent. Data is commonly created with missing values, inaccuracies or other errors. Also, separate data sets often have different formats that must be reconciled when the...
