The goal is to understand the type of problem to state.

I: Introduction

The introductory part includes research goals and motivations. It reasons the research with fundamental and state-of-the-art references. It delivers the main message of the work to the reader. This message shows the novelty of this work in comparison to recent results.

Write Introduction. The expected size is one page. The expected plan is:

  1. the research goal (and its motivations),
  2. the object of research (introduce main termini),
  3. the problem (what is the challenge),
  4. methodology: literature review and state-of-the-art
  5. the project tasks,
  6. the proposed solution, its novelty, and advantages,
  7. the pros and cons of recent works,
  8. goal of the experiment, set up, data sets, workflow.

Also, to refine your Introduction:

  1. Create the file Surname2018Title.bib for your project.
  2. Move from the file LinkReview to bibliographic records in the BibTeX format.
    • Check the correctness of the BibTeX database (styles of authors' names, volumes of journals, page numbers).
    • Use bibliographic databases to facilitate your work.
    • Use the default style \bibliographystyle{plain} before the bibliography section \bibliography{ProjectN}.

P: Problem statement

In the paradigm Idea\(\to\)Formula\(\to\)Code state the problem to find an optimal solution.

  1. Discuss the problem statement with your adviser.
  2. See the examples below and in past projects.
  3. Discuss terminology and notation. See [pdf] and [tex] with notations and a useful style file.
  4. At the beginning of the Problem statement, write a general problem description.
  5. Describe the elements of your problem statement:
    1. the sample set,
    2. its origin, or its algebraic structure,
    3. statistical hypotheses of data generation,
    4. [conditions of measurements],
    5. [restrictions of the sample set and its values],
    6. your model in the class of models,
    7. restrictions on the class of models,
    8. the error function (and its inference) or a loss function, a quality criterion,
    9. cross-validation procedure,
    10. restrictions to the solutions,
    11. external (industrial) quality criteria,
    12. the optimization statement as \(\arg\min\).
  6. Define the main termini: what is called the model, the solution, and the algorithm.

Note that:

  • The model is a parametric family of functions that map design space to target space.
  • The criterion (error function) is a function to optimize and get an optimal solution (model parameters, a function).
  • The algorithm transforms solution space, usually iteratively.
  • The method combines a model, a criterion, and an algorithm to produce a solution.

Check it:

  • the regression model,
  • the sum of squared errors,
  • the Newton-Raphson algorithm,
  • the method of least squares.
