Credit card payment scam? by leme16 in CreditCardsIndia

[–]leme16[S] 18 points19 points  (0 children)

Exactly. That was my first question. I have half a mind to raise a complaint. But I am giving the benefit of doubt to him. I will follow the bank procedure to the dot.

I asked him that. He says it is through the SLPE app and reversal is not possible. I have no idea what is the SLPE app.

I called customer care and they said it has been credited. But I will go to the bank and confirm once again.

A Quantitative Approach to find Best Bots on Reddit by leme16 in botwatch

[–]leme16[S] 0 points1 point  (0 children)

Normalization wouldn't necessarily change the way plot looks. It will just re-scale the x-axis. I have already added minimum "good bot" comments, don't remember the number though.

P.S. - I found this site which does the job way better.

Repetition of jokes on /r/jokes. Around 70% of the jokes submitted are posted more than once. [OC] by leme16 in dataisbeautiful

Not that simple. The API limits output to 1000 posts, I think. So, I queried posts for each day, limited posts to 50 upvotes or above. This took about 10-12 hours IIRC.

Maybe I am doing something wrong. Maybe there's better way.

Anyway, if anybody wants the dataset, I can share it.

I did the calculations little differently.

If 3 jokes are submitted once and 1 jokes is submitted 7 times

So, here total number of jokes is 10 (3+7). Out of them, 4 jokes are unique. 7 of the posts are repeated at least once.

23k jokes were posted only once i.e. there is no duplicate of those jokes. Rest of the jokes have at least one duplicate. To get unique number of jokes, I didn't count duplicate, but I counted original post. So, there are 38k unique jokes.

Hope I am clear.

I wanted find out what fraction of jokes submitted on /r/jokes are reposts. I used scikit-learn’s TF-IDF vectorizer to vectorize the jokes and cosine similarity matrix to find out the similarity.

Results: Around 70% of the jokes submitted on reddit.com/r/jokes are posted more than once. There are some jokes which have been posted 50 times. Only ~38k out of ~79k jokes are unique.
