Analysis

Analysis#

Analysis is the operator’s catalog of algorithms and techniques for turning data into facts. Each entry below is a primitive, a well-understood method with known assumptions, known costs, and known failure modes. The operator composes them into larger systems: detectors that page on anomalies, dashboards that show trends, classifiers that route work, recommendations that surface priorities, signatures that match adversary behavior.

The aim of this section is to be a working reference an operator can read in one sitting and reach for during a build. Each page defines the technique, names the standard implementations, shows the operator-shaped use, and points at the next layer when the problem outgrows the primitive.

For mission-level analysis (target-centric tradecraft, OSINT synthesis, finished-intelligence production), see Analysis. For the engineering side of running analysis at scale (warehouses, streaming, ML pipelines), see Cloud and Databases. This section is the methods themselves.

Statistics

Descriptive and inferential statistics. The substrate every later technique stands on.

Statistics
Time Series

Decomposition, smoothing, forecasting. For anything indexed by time.

Time Series
Supervised Learning

Regression and classification. Given labels, predict the next one.

Supervised
Unsupervised Learning

Clustering and dimensionality reduction. Find structure without labels.

Unsupervised
Anomaly Detection

Anomaly and change-point detection. Surface the unusual.

Anomaly Detection
Graph Analytics

Shortest paths, centrality, community, link prediction.

Graph
Text Analytics

Tokenisation, embedding, classification, extraction.

Text
Streaming

Online and approximate algorithms for unbounded data.

Streaming
Search and Similarity

Information retrieval, ranking, similarity, recommendation. Vector space models and nearest-neighbor search.
