代写data编程、代做R编程语言、R程序调试-代写Algorithm 算法作业

Homework 6

1. From the Indiegogo (https://webrobots.io/indiegogo-dataset/ ) dataset you need to download at

least 5 JSON (or CSV) files. Use the content of “tagline” or “title” from downloaded files.

2. Extract the article title from your downloaded dataset and use “bag of words” to convert the

article title into set of words (3 points).

3. Use Latent Semantic Analysis (LSA) or Latent Dirichlet Allocation (LDA) to cluster them (4

points). You need to do research online about how using

LSA and LDA and do they work, we did not develop them in the class, to enforce you do the

research on your own.

4. Visualize the article clustering results, in a dendrogram or heatmap (3 points). Please be sure

to show a clean dendrogram and not a sloppy dendrogram. Delivering an imbalanced unclear

dendrogram, or a heatmap with too small text, will result in reducing your grade. You might

need to annotate your dendrogram by hand and add information to it. Please make the

dendrogram nice and clean, one line represents one thing

Please make the visualization nice. Add more setting of the visualization.

Besides, please spend time and create a proper visualization for your experiment. At this time,

you should be able to create proper visualization and do not rely on default font settings.

You need to prepare a report on your tasks and findings along with a video file describing what

you have done. You can copy paste your codes, its results and your description into a Word

document, Python Notebook or you can use R notebook.

Your deadline for delivering this home work is written on the blackboard online. Please send

your questions to TA and if required to RA.
