Supervised Categorical-Value Prediction Task

A Supervised Categorical-Value Prediction Task is a data-driven classification task that is a supervised learning task (that requires a labeled record dataset).

• AKA: Inductive Classification, Supervised Classification Task.
• Context:
  • Input: a Labeled Record Dataset (with a target attribute that is a nominal attribute).
  • output: one or more predicted class labels (for each testing record).
    • Optional Output: a Learned Classification Function.
    • Optional Output: a Confidence Score (for each value).
  • It can range from being a Fully-Supervised Classification Task to being a Semi-Supervised Classification Task, depending on the presence of unlabeled learning records.
  • It can range from being a Ranking Supervised Classification Task to being a Probabilistic Supervised Classification Task, depending on the requirement for a probability value.
  • It can range from being a Supervised Two-Class Classification Task to being a Supervised Multi-Class Classification Task, depending on the class set size.
  • It can range from being a Univariate Supervised Classification Task to being a Multivariate Supervised Classification Task, depending on the feature set size.
  • It can range from being a Supervised One-Label Classification Task to being a Supervised Multi-Label Classification Task, depending on the number of class labels to predict.
  • It can range from being an Online Supervised Classification Task to being an Offline Supervised Classification Task, depending on the incremental availability of data.
  • It can range from being a IID Supervised Classification Task to being an Non-IID Supervised Classification Task (such as temporal supervised classification), depending on whether it receives IID data).
  • It can range from being a Model-based Supervised Classification Task to being an Model-free Supervised Classification Task, depending on the requirement of a classification model.
  • It can range from being a Large Sparse Data Classification Task to being ...
  • It can be solved by a Supervised Classification System and implements a Supervised Classification Algorithm.
• Example(s):
  • a Benchmark Supervised Classification Task, such as a UCI Census Data.
  • a Logistic Regression Training Task, that requires a logistic function.
  • a Classification Rule Learning Task.
  • a Supervised Text Document Classification Task.
  • a Supervised Spam Email Classification Task.
  • a Supervised Optical Character Classification Task.
  • a Classification Tree Learning Task.
  • ...
• Counter-Example(s):
  • a Supervised Point Estimation Task.
  • an Unsupervised Classification Task.
  • a Supervised Ordinal Prediction Task.

    Classification learning is sometimes called supervised because, in a sense, the scheme operates under supervision by being provided with actual outcome for each of the training examples ...

  • QUOTE: Inductive learning is the explicit or implicit creation of general concept or class descriptions from examples. Many induction problems It can be described as follows. A training set of preclassified examples is given, where each example (also called observation or case) is described by a vector of features or attribute values, and the goal is to form a description that can be used to classify previously unseen examples with high accuracy.
