Machine Learning:Supervised Classification

  • Given:

    • A description of an instance, d ∈ X

      • X is the instance language or instance space.

    • A fixed set of classes:

    • C = {c1, c2,…, cJ}

    • A training set D of labeled documents with each labeled document ⟨d,c⟩ ∈ X×C

  • Determine:

    • A learning method or algorithm which will enable us to learn a classifier γ:X→C

    • For a test document d, we assign it the class γ(d) ∈ C
