A researcher is working with a large dataset of patient medical records with numerous features. They want to visualize the data in 2D to spot any potential patterns or groupings but without necessarily clustering the data. Which technique would they most likely employ?

  • Principal Component Analysis
  • t-Distributed Stochastic Neighbor Embedding (t-SNE)
  • K-Means Clustering
  • DBSCAN
The researcher would most likely employ t-Distributed Stochastic Neighbor Embedding (t-SNE). t-SNE is a dimensionality reduction technique suitable for visualizing high-dimensional data in 2D while preserving data relationships and patterns without imposing clusters.
