CADS Non-Linear Supervised Learning Algorithms

Models that do not make strong assumptions about the form of the mapping function are called nonparametric machine learning models. By not making assumptions, they are free to learn any functional form from the training data.

“Nonparametric methods are good when you have a lot of data and no prior knowledge, and when you don’t want to worry too much about choosing just the right features.” [Artificial Intelligence: A Modern Approach, page 757]

Nonparametric methods seek to best fit the training data in constructing the mapping function, whilst maintaining some ability to generalise to unseen data. As such, they are able to fit a large number of functional forms. An easy to understand nonparametric model is the k-nearest neighbors algorithm that makes predictions based on the k most similar training patterns for a new data instance. The method does not assume anything about the form of the mapping function other than patterns that are close are likely have a similar output variable.

Benefits of Non-parametric Machine Learning Algorithms

  • More Flexibility: Capable of fitting a large number of functional forms.
  • High Power: No assumptions (or weak assumptions) about the underlying function.
  • High Performance: Can result in higher performance models for prediction.

Limitations of Non-parametric Machine Learning Algorithms

  • More Training Data: Require a lot more training data to estimate the mapping function.
  • Low Efficiency: A lot slower to train as they often have far more parameters to train.
  • Overfitting: More of a risk to overfit the training data and it is harder to explain why specific predictions are made.

    The term “non-parametric” might sound a bit confusing at first: non-parametric does not mean that they have NO parameters! On the contrary, non-parametric models (can) become more and more complex with an increasing amount of data.

Data Science

Data science is not a single science as much as it is a collection of various scientific disciplines integrated for the purpose of analyzing data. These disciplines include various statistical and mathematical techniques, including:

  • Computer science
  • Data engineering
  • Visualization
  • Domain-specific knowledge and approaches

With the advent of cheaper storage technology, more and more data has been collected and stored permitting previously unfeasible processing and analysis of data. With this analysis came the need for various techniques to make sense of the data. These large sets of data, when used to analyze data and identify trends and patterns, become known as big data.

The process of analyzing big data is not simple and evolves to the specialization of developers who were known as data scientists. Drawing upon a myriad of technologies and expertise, they are able to analyze data to solve problems that previously were either not envisioned or were too difficult to solve.

The various data science techniques that we will illustrate have been used to solve a variety of problems. Many of these techniques are motivated to achieve some economic gain, but they have also been used to solve many pressing social and environmental problems. Problem domains where these techniques have been used include finance, optimizing business processes, understanding customer needs, performing DNA analysis, foiling terrorist plots, and finding relationships between transactions to detect fraud, among many other data-intensive problems.

Data mining is a popular application area for data science. In this activity, large quantities of data are processed and analyzed to glean information about the dataset, to provide meaningful insights, and to develop meaningful conclusions and predictions. It has been used to analyze customer behavior, detecting relationships between what may appear to be unrelated events, and to make predictions about future behavior.

Machine learning is an important aspect of data science. This technique allows the computer to solve various problems without needing to be explicitly programmed. It has been used in self-driving cars, speech recognition, and in web searches. In data mining, the data is extracted and processed. With machine learning, computers use the data to take some sort of action.
