Staying current with research in Computer Vision - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to import a popular library for accessing research papers.

Computer Vision

import [1]

Drag options to blanks, or click blank then click option'

Amatplotlib

Btensorflow

Cnumpy

Darxiv

💡 Hint

Common Mistakes

Importing general ML libraries like tensorflow instead of a research paper library.

Using visualization libraries which don't help access papers.

The 'arxiv' library helps access research papers programmatically, which is useful to stay current with research.

2fill in blank

medium

Complete the code to search for recent papers on 'computer vision' using the arxiv API.

Computer Vision

search = arxiv.Search(query='computer vision', max_results=[1])

Drag options to blanks, or click blank then click option'

A500

B5

C50

D0

💡 Hint

Common Mistakes

Using 0 which returns no results.

Using 500 which may be too large and slow.

Setting max_results to 50 retrieves a reasonable number of recent papers to review.

3fill in blank

hard

Fix the error in the code to print the titles of the papers found.

Computer Vision

for result in search.[1]():
    print(result.title)

Drag options to blanks, or click blank then click option'

Aget_results()

Bget_results

Cresults

Dresults()

💡 Hint

Common Mistakes

Using 'get_results' instead of 'results'.

Using options with extra parentheses like 'results()' or 'get_results()'.

The arxiv Search object uses the method results() to return an iterable of results.

4fill in blank

hard

Fill both blanks to filter papers published after 2022 and sort them by relevance.

Computer Vision

search = arxiv.Search(query='computer vision', max_results=100, sort_by=[1], sort_order=[2], 
    date_from='2023-01-01')

Drag options to blanks, or click blank then click option'

Aarxiv.SortCriterion.Relevance

Barxiv.SortCriterion.SubmittedDate

Carxiv.SortOrder.Ascending

Darxiv.SortOrder.Descending

Attempts:

💡 Hint

Common Mistakes

Sorting by date instead of relevance.

Using ascending order which shows least relevant first.

Sorting by relevance descending shows the most relevant recent papers first.

5fill in blank

hard

Fill all three blanks to create a dictionary of paper titles and their authors for papers with more than 2 authors.

Computer Vision

papers = {result.[1]: result.[2] for result in search.results() if len(result.[3]) > 2}

Drag options to blanks, or click blank then click option'

Atitle

Bauthors

Dsummary

💡 Hint

Common Mistakes

Using 'summary' instead of 'authors' for filtering.

Mixing up keys and values in the dictionary comprehension.

We use 'title' as key, 'authors' as value, and check length of 'authors' list to filter papers.
