Source-derived summary

LIBSVM and LIBLINEAR are two popular open source machine learning libraries, both developed at the National Taiwan University and both written in C++ though with a C API. LIBSVM implements the sequential minimal optimization (SMO) algorithm for kernelized support vector machines (SVMs), supporting classification and regression.

LIBLINEAR implements linear SVMs and logistic regression models trained using a coordinate descent algorithm.

The SVM learning code from both libraries is often reused in other open source machine learning toolkits, including GATE, KNIME, Orange and scikit-learn.

Bindings and ports exist for programming languages such as Java, MATLAB, R, Julia, and Python. It is available in e1071 library in R and scikit-learn in Python.

Both libraries are free software released under the 3-clause BSD license.

Editorial summary

Begin with the source’s own compact description: “LIBSVM” is library for support vector machines. The dossier treats that line as a proposition to test through LIBSVM, library and support, not as a finished interpretation.

Editorial reviewA valuable geographic starting point for tracing changing names, boundaries, uses and administrative responsibility. The current 121-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, LIBSVM, library and support is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “library for support vector machines” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 4, 2026. The linked authority identifier is Q17064545.

Critical limits

Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.

Three-step research path

  1. Establish the record: confirm the title “LIBSVM”, its source revision and the description used here.
  2. Expand the search: follow LIBSVM primary sources, LIBSVM archive and LIBSVM research across catalogues and specialist indexes.
  3. Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.

Questions for further research

  1. Which source most directly establishes the central claim about “LIBSVM”?
  2. Which earlier names or jurisdictions may reveal additional records?
  3. Which authority defined the place, boundary or structure at the relevant date?
