Data Preparation for Machine Learning

Effective data preparation ensures that the machine learning algorithms receive high-quality data. This leads to improved model accuracy and robustness. Use our data preparation tool to produce well curated data for your machine learning projects.

Data preparation for Machine Learning - Zoho DataPrep

How modern Data Preparation tools help in Machine Learning projects

Data Preparation tools like Zoho DataPrep allow data professionals to visually and interactively explore, clean, combine, and shape data for training and deploy machine learning models and production data pipelines to accelerate innovation with AI. It cuts down the time to prepare data, such as removing duplicates and removing invalid entries, and allows data scientists to focus on insights and analysis. Teams can collaborate, reuse, and share data sources, datasets, and recipes.

Key steps involved in preparing data for machine learning

  • Remove duplicate data

    Duplicates present in the data are one of the most commonly faced issues during data preparation for machine learning. Zoho DataPrep helps you remove duplicate data by identifying duplicates based on columns or entire rows.

  • Fix invalid and missing data

    Zoho DataPrep enables you to quickly find invalid and missing data using the data quality chart, and helps you to fix them using intelligent suggestions. Fix missing values using a static value, the column average, forward or backward filling techniques or just filter and remove the rows with empty values.

  • Decompose and aggregate

    Split and extract features from a column that are useful to a machine learning model when split into its constituent parts. Certain other features can also be aggregated into a single column when it is meaningful to the ML model.

  • Parse unstructured data

    Data available in the log files or text files can be extracted using smart selection transforms and other text extraction methods available in Zoho DataPrep. The custom pattern syntax helps users express themselves far more effectively compared to regex.

  • Categorize data

    Cluster continuous numeric data into categorical data, by categorizing data into buckets. Create quantile, equally spaced, or custom buckets using DataPrep.
