discussion on how we can use statistical methods to measure and improve the efficacy of http://freeCodeCamp.com

Occasionally people stop by and ask about mathematics for machine learning. Just ran into this book that may prove useful https://mml-book.github.io/. Short-ish book of about 400 pages and it is free to download. It will also be published eventually if you want a physical copy. I ran into this while reading through this thread books to read for deep learning in case you want to dig a bit deeper.

Oh this is pretty cool. I'm a bit late to the party, but it looks like Kaggle (known for data science prediction competitions) has a YouTube playlist of their reading group https://www.youtube.com/playlist?list=PLqFaTIg4myu8t5ycqvp7I07jTjol3RCl9

Here's the details if you wanna join in for the continuing discussions https://twitter.com/rctatman/status/1131621843188604928

A very extensive glossary of statistics https://discourse.datamethods.org/t/glossary-of-statistical-terms/1220

For a gem, see the definition for "data science" 🧐🙃

Hi Guys , I am trying to deploy the opencv in the heroku using the python flask . I am getting the following error : ImportError: libSM.so.6: cannot open shared object file: No such file or directory
Is there any way to deploy the opencv in the heroku ?

Give this a try @bommojuvishu

chance = 0
while chance <=3:
        guess = int(input("Guess: "))
        if guess == 9:
                print("try again")
               chance+1
       else:
                print("try again")
        chance+=1
print(chance) #why does this print 4 instead of 3 when you enter the integer 9?

Eric Leung

@erictleung

@Koderkid1936 your while loop will allow chance to equal 3. So it will go through the loop once more and run the line chance += 1 again, thus making chance equals to 4 as it has printed out.

@Koderkid1936 this link might help you visualize what your code is doing. It will create diagrams of what your code is doing as you go through it line by line.

@Koderkid1936

@erictleung thanks alot much appreciated, i think im starting to understand the flow of the program it executes the chance+=1 statement beofre the while loop.. i think but i will do more research thanks :thumbsup:

Random comment. So I'm helping out with a data science boot camp in town and last time I checked, in one of their modules, they are using one of the freeCodeCamp new coder surveys as one of their datasets! So crazy that something I've had a hand in cleaning up has come full circle for me to see again :laughing:

Philip Durbin

@pdurbin

Can you please link me to that dataset? I'll take it under consideration for dataverse-sample-data. :)

Eric Leung

@erictleung

@pdurbin I think they used this one found here https://github.com/freeCodeCamp/2016-new-coder-survey/tree/master/clean-data

@BuntyBru

Hi guys 

Can anyone mention good courses for data science for complete beginners ( person who hasn't had attachment with tech ever and is a business graduate)
I did some google search for this  
But wanted to know some personal reviews

Thanks

Philip Durbin

@pdurbin

@erictleung oh, right, we talked about this FCC dataset at freeCodeCamp/2017-new-coder-survey#7 :) Do you want to hear more about dataverse-sample-data? :)

Eric Leung

@erictleung

@BuntyBru here's a great list to check out https://www.freecodecamp.org/news/if-you-want-to-learn-data-science-start-with-one-of-these-programming-classes-fb694ffe780c/

@BuntyBru here's a general list of awesome programming and data science materials as well https://github.com/P1xt/p1xt-guides

Eric Leung

@erictleung

@pdurbin I was a bit curious about it :) You mentioned it so casually!

@sa-js

Hey all. I am a camper and recently wrote an article on Medium. Give it a read guys : https://medium.com/@saeeddev/learn-how-to-store-data-for-your-data-science-problems-even-if-you-dont-want-to-27e02dd9f781?source=friends_link&sk=8139c568a7fe885d9b560e7cde7035b2. Plus also let me know how can I get it featured on FCC New Section

thanks Eric

@pdurbin

@erictleung here is where I recently announced dataverse-sample-data: https://groups.google.com/d/msg/dataverse-community/u-Yv0U3v4Bo/NgBfDrDlAgAJ . I'm wondering if you (or anyone else here) is interested in contributing any datasets. :)

Alice Jiang

@becausealice2

@erictleung you're famous. Remember us

Philip Durbin

@pdurbin

heh

Alice Jiang

@becausealice2

if anyone is looking for free data, I've just discovered the Food and Agriculture Organization of the United Nations' FAOSTAT and OHMYGOD so much information

(in case it needs to be stated explicitly, it's all agricultural-related data)

@ruitoantunes

i'm starting programming in php and would like to have some support on the php code

Alice Jiang

@becausealice2

@ruitoantunes I don't know that many people here would be able to help with PHP, it's not a very common language in Data Science. Perhaps if you share a code snippet someone could have a look?

ruitoantunes

@ruitoantunes

Ok thanks.

Sakitha

@Sakitha

Hi, does apply in df.apply(fun) iterate over each columns in 'df' data-frame and pass them to 'fun' function as a series?

Eric Leung

@erictleung

@Sakitha hi there! What language and package are you working with? I'm assuming Python and pandas but just wanna be sure.

Alice Jiang

@becausealice2

@Sakitha :point_up: making that same assumption, yes. Each column is passed as a Series object to fun

Philip Durbin

@pdurbin

I like the sound of apply(fun)

Alice Jiang

@becausealice2

I wonder what that does :weary:

I shouldn't be so dramatic :laughing:

hello, anybody here? :smile:

Philip Durbin

@pdurbin

Some of us are here. :) What can we do for you?

abraham anak agung

@padunk

@pdurbin It is ok, SO to the rescue :smile: . Just confuse why np.std() return different value compare to pandas std.

Philip Durbin

@pdurbin

np is numpy, I assume

Hey

@Anu-Pra

Hey

Is anyone interested in forming a study group for learning P1xt Data Science guide?

I need a study partner

Eric Leung

@erictleung

@padunk if you remember, what is the difference between np.std() and pd.std()? I'd like to know :smile:
