Data preprocessing is the process of transforming raw data into a format that is easier to analyze. This process can include cleaning steps, such as handling missing values or smoothing noisy data. By cleaning, organizing, and summarizing the data, you can identify patterns, make predictions, ...
Data preprocessing refers to the essential step of cleaning and organizing data before it is used in a data-driven neural network algorithm. It involves removing any incorrect or irrelevant data and ensuring that the correct data is inputted into the models. This process may include tasks such as...

1 数据预处理（data preprocessing）是指在主要的处理以前对数据进行的一些处理。现实世界中数据大体上都是不完整，不一致的脏数据，无法直接进行数据挖掘，或挖掘结果差强人意。为了提高数据挖掘的质量产生了数据预处理技术。数据预处理有多种方法：数据清理，数据集成，数据变换，数据归约等。这些数据处理技术在数据...
Data preprocessing is the second stage of the workflow for predictive maintenance algorithm development: Data preprocessing is often necessary to clean the data and convert it into a form from which you can extract condition indicators. Data preprocessing can include: ...
