KNIME Analytics Platform

KNIME Analytics Platform is the open-source software for creating data science. Intuitive, open, and continuously integrating new developments, KNIME for Windows PC makes understanding data and designing data science workflows and reusable components accessible to everyone.

Open and combine simple text formats (CSV, PDF, XLS, JSON, XML, etc), unstructured data types (images, documents, networks, molecules, etc), or time-series data. Connect to a host of databases and data warehouses to integrate data from Oracle, Microsoft SQL, Apache Hive, and more. Load Avro, Parquet, or ORC files from HDFS, S3, or Azure. Access and retrieve data from sources such as Twitter, AWS S3, Google Sheets, and Azure.

Derive statistics, including mean, quantiles, and standard deviation, or apply statistical tests to validate a hypothesis. Integrate dimensions reduction, correlation analysis, and more into your workflows. Aggregate, sort, filter, and join data either on your local machine, in-database, or in distributed big data environments.

Clean data through normalization, data type conversion, and missing value handling. Detect out of range values with outlier and anomaly detection algorithms. Extract and select features (or construct new ones) to prepare your dataset for machine learning with genetic algorithms, random search, or backward- and forward feature elimination. Manipulate text, apply formulas on numerical data, and apply rules to filter out or mark samples.

Build machine learning models for classification, regression, dimension reduction, or clustering, using advanced algorithms including deep learning, tree-based methods, and logistic regression. Optimize model performance with hyperparameter optimization, boosting, bagging, stacking, or building complex ensembles. Validate models by applying performance metrics including Accuracy, R2, AUC, and ROC. Perform cross-validation to guarantee model stability.

Explain machine learning models with LIME, Shap/Shapley values. Understand model predictions with the interactive partial dependence/ICE plot. Make predictions using validated models directly, or with industry-leading PMML, including on Apache Spark.

Visualize data with classic (bar chart, scatter plot) as well as advanced charts (parallel coordinates, sunburst, network graph, heat map) and customize them to your needs. Display summary statistics about columns in a KNIME Analytics Platform table and filter out anything that's irrelevant. Export reports as PDF, PowerPoint, or other formats for presenting results to stakeholders. Store processed data or analytics results in many common file formats or databases.

Build workflow prototypes to explore various analysis approaches. Inspect and save intermediate results to ensure fast feedback and efficient discovery of new, creative solutions. Scale workflow performance through in-memory streaming and multi-threaded data processing. Exercise the power of in-database processing or distributed computing on Apache Spark to further increase computation performance. Download KNIME Analytics Platform and build your first workflow!
