Gender Classification Challenge for 'Learn Python for Data Science #1' by @Sirajology on YouTube

gender_classification_challenge

##Overview

This is the code for the gender classification challenge for 'Learn Python for Data Science #1' by @Sirajology on YouTube. The code uses the scikit-learn machine learning library to train a decision tree on a small dataset of body metrics (height, width, and shoe size) labeled male or female. Then we can predict the gender of someone given a novel set of body metrics.

##Dependencies

• Scikit-learn (http://scikit-learn.org/stable/install.html)
• numpy (pip install numpy)
• scipy (pip install scipy)

Install missing dependencies using pip

##Usage

Once you have your dependencies installed via pip, run the script in terminal via

python demo.py

##Challenge

Find 3 more classifiers from the sci-kit learn documentation and add them to the demo.py code. Train them on the same dataset and compare their results. You can determine accuracy by trying to predict testing you trained classifier on samples from the training data and see if it correctly classifies it. Push your code repository to github then post it in the comments. I'll give the winner a shoutout a week from now!

##Credits

Credits for some of the code go to chribsen. I've merely created a wrapper to get people started easily.

gender_classification_challenge's Issues

Running demo.py gives this error :

Running demo.py gives this error :

Decision tree with string values

Hey there how are you,

I am new to python and doing PBL learning, I was looking at the challenge with the classifier, and wanted to run the same decision tree but with other classifiers as string values to determine either male or female by Movie title, hair length and food. Here is the code to see if you can help me, and this is the error I get when running it.

Code:

from sklearn import tree

clf = tree.DecisionTreeClassifier()

#[movie, hair, food]
X = [['Black Panther', 'Long', 'Burger'],
['Avengers', 'Short', 'Taco'],
['96', 'Long', 'Pizza'],
['Spiderman', 'Long', 'Burrito'],
['Roma', 'Short', 'Cheesesteak'],
['Greenbreak', 'Long', 'Icecream'],
['A star is Born', 'Long', 'Hot Pocket'],
['The favourite', 'Short', 'Nachos'],
['A quiet place', 'Long', 'Salad'],
['Ant-man', 'Short', 'Pop-corn'],
['Solo', 'Long', 'Chocolate']]

Y = ['male', 'male', 'female', 'female', 'male', 'male', 'female', 'female',
'female', 'male', 'male']

clf = clf.fit(X, Y)

prediction = clf.predict([['Mary Poppins','Long','Candy']])

print(prediction)

Error:

Traceback (most recent call last):
File "D:\Python\demo2.py", line 21, in
clf = clf.fit(X, Y)
File "D:\Python\lib\site-packages\sklearn\tree\tree.py", line 801, in fit

array = np.asarray(array, dtype=dtype, order=order)
File "D:\Python\lib\site-packages\numpy\core\numeric.py", line 538, in asarray
return array(a, dtype, copy=False, order=order)
ValueError: could not convert string to float: 'Black Panther'

Cannot contribute (create pull request or push to origin)

There is a spelling mistake and it is very distracting

instead of 'reusults' it should be 'results'

I wanted to help. So I created a commit.

But I'm not able to push it to origin

I tried to create a pull request but the button is disabled

Failed building wheel for scipy
Running setup.py clean for scipy
Complete output from command c:\python27\python.exe -u -c "import setuptools, tokenize;file='c:\users\florinb\appd

setup.py clean is not supported, use one of the following instead:

- `git clean -xdf` (cleans all files)
- `git clean -Xdf` (cleans all versioned files, doesn't touch
                    files that aren't checked into the git repo)

Add --force to your command to use it anyway if you must (unsupported).

ImportError: No module named sklearn

Hi Siraj,

I'm a beginner in machine learning, I'm started learning from your Youtube videos, that way I here, I got

Traceback (most recent call last):
  File "demo.py", line 1, in <module>
    from sklearn import tree
ImportError: No module named sklearn

error when to execute demo.py here is env

please help me thod fix this

Thanks,
