Embedding projector

The embedding projector is a tool for uncovering patterns in unstructured data that can be used to diagnose systemic model and labeling errors. The embedding projector works for Data Rows that have embeddings. Most embeddings have much higher dimensions than 2 or 3, making it impossible to identify global patterns. You can use the projector tool to employ dimensionality reduction algorithms to explore embeddings in 2D interactively. You can navigate to the embedding projector by using the icons in the top right.

We support two algorithms for dimensionality reduction, PCA & UMAP, which can be toggled. PCA is much faster but does not attempt to find clusters in the data. UMAP is better for trying to find regions of similar points in the data. Sphereize data normalizes the data by subtracting the mean and dividing by the norm.

To learn more about UMAP and dimensionality reduction, check out this guide below from Google.

Use the selection tool to isolate data rows for further investigation. To drill into a set of data rows further, you can click the selected data rows button in the top right and click Filter to select. This will re-run the dimensionality reduction algorithm you selected on the subset of data rows to surface local clusters in the data.
