Mapping intrinsic rank and informational gravity in complex tabular data: I developed a non-parametric, model-agnostic, information-theoretic diagnostic to bypass the limits of linear, rank, and Euclidean baselines. [R]
Navigating complex tabular data often reveals limitations with standard dimensionality reduction techniques like PCA. To address this, I’ve developed a non-parametric, model-agnostic diagnostic leveraging information theory to bypass these constraints. The "Entropic Scree" accurately maps intrinsic rank and “informational gravity,” distinguishing shared signal from noise and revealing hidden topological structures—even in datasets where features exceed samples. Explore the methodology and open-source framework on GitHub to transform your data exploration and inform architectural decisions for downstream AI models.
How to Optimize Vector Search When RAM Gets Too Expensive: On-Disk vs. In-Memory ANN Indexes
Scaling vector search can quickly strain RAM resources. This post tackles a critical challenge: optimizing performance when memory becomes a bottleneck. We explore the trade-offs between in-memory and on-disk Approximate Nearest Neighbor (ANN) indexes, comparing HNSW, SPANN, and DiskANN to architect cost-effective infrastructure. Discover practical strategies for navigating latency and storage considerations, ensuring efficient vector search even with limited RAM.
