Python代寫｜Assignment代寫 - CSE 158/258, Fall 2020: Assignment
This is an open-ended assignment in which you are expected to write a detailed report documenting
your results. Please submit your solution electronically via gradescope, on or before Dec 7 (Monday
Submissions should be in the form of a written report, which is expected to be at least four pages
(double column, 11pt), or roughly 2.5-3 thousand words, plus figures, tables, and equations. See an
example template in the lecture slides to get an idea of the length expected.
Examples of datasets and projects that may be of interest in this assignment will be discussed in the
lectures, though you may use any dataset you wish (including the ones we used for Assignment 1). For a
selection of datasets that I frequently use, see http://cseweb.ucsd.edu/~jmcauley/datasets.html
Assignments will be graded based on their coverage of the following five components. Examples of what
might be included in these sections and previous assignment examples shall be described in more detail
in class. Each of the five sections below will contribute approximately 5 percent of your grade, for a total
of 25 percent for the whole assignment.
1. Identify a dataset to study, and perform an exploratory analysis of the data. Describe the dataset,
including its basic statistics and properties, and report any interesting findings. This exploratory analysis
should motivate the design of your model in the following sections. Datasets should be reasonably large
(e.g. more than 50,000 samples).
2. Identify a predictive task that can be studied on this dataset. Describe how you will evaluate your
model at this predictive task, what relevant baselines can be used for comparison, and how you will
assess the validity of your model’s predictions. It’s fine to use models that were described in class here
(i.e., you don’t have to invent anything new (though you may!)), though you should explain and justify
which model was appropriate for the task. It’s also important in this section to carefully describe what
features you will use and how you had to process the data to obtain them.
3. Describe your model. Explain and justify your decision to use the model you proposed. How will you
optimize it? Did you run into any issues due to scalability, overfitting, etc.? What other models did you
consider for comparison? What were your unsuccessful attempts along the way? What are the strengths
and weaknesses of the different models being compared?
4. Describe literature related to the problem you are studying. If you are using an existing dataset,
where did it come from and how was it used? What other similar datasets have been studied in the past
and how? What are the state-of-the-art methods currently employed to study this type of data? Are the
conclusions from existing work similar to or different from your own findings? 5. Describe your results
and conclusions. How well does your model perform compared to alternatives, and what is the
significance of the results? Which feature representations worked well and which do not? What is the
interpretation of your model’s parameters? Why did the proposed model succeed why others failed (or
if it failed, why did it fail)?
