Psudo :
1.Get a Dataset
2.arbitarily choose K centroids in random
3.Assign the closest data points by distance to a centroid/cluster
4.Compute mean of the datapoints in the clusters excluding the centroids
5.The mean would be the new centroid and repeat from step 3 until the centroid doesnt change.

# Python Unittest
# unittest.mock � mock object library
# unittest.mock is a library for testing in Python.
# It allows you to replace parts of your system under test with mock objects and make assertions about how they have been used.
# unittest.mock provides a core Mock class removing the need to create a host of stubs throughout your test suite.
# After performing an action, you can make assertions about which methods / attributes were used and arguments they were called with.
# You can also specify return values and set needed attributes in the normal way.
#
# Additionally, mock provides a patch() decorator that handles patching module and class level attributes within the scope of a test, along with sentinel
# for creating unique objects.
#
# Mock is very easy to use and is designed for use with unittest. Mock is based on the �action -> assertion� pattern instead of �record -> replay� used by
# many mocking frameworks.
#
#
# patch methods: start and stop.
# All the patchers have start() and stop() methods.
# These make it simpler to do patching in setUp methods or where you want to do multiple patches without nesting decorators or with statements.
# To use them call patch(), patch.object() or patch.dict() as normal and keep a reference to the returned patcher object.
# You can then call start() to put the patch in place and stop() to undo it.
# If you are using patch() to create a mock for you then it will be returned by the call to patcher.start.
#
patcher _ patch('package.module.ClassName')
____ package ______ module
original _ module.ClassName
new_mock _ patcher.start()
a.. module.ClassName __ no. original
a.. module.ClassName __ new_mock
patcher.stop()
a.. module.ClassName __ original
a.. module.ClassName __ no. new_mock
#
# A typical use case for this might be for doing multiple patches in the setUp method of a TestCase:
#
c_ MyTest(T..
___ setUp
patcher1 _ patch('package.module.Class1')
patcher2 _ patch('package.module.Class2')
MockClass1 _ patcher1.start()
MockClass2 _ patcher2.start()
___ tearDown
patcher1.stop()
patcher2.stop()
___ test_something
a.. package.module.Class1 __ MockClass1
a.. package.module.Class2 __ MockClass2
MyTest('test_something').run()
#
# Caution:
# If you use this technique you must ensure that the patching is �undone� by calling stop.
# This can be fiddlier than you might think, because if an exception is raised in the setUp then tearDown is not called.
# unittest.TestCase.addCleanup() makes this easier:
#
c_ MyTest(T..
___ setUp
patcher _ patch('package.module.Class')
MockClass _ patcher.start()
addCleanup(patcher.stop)
___ test_something
a.. package.module.Class __ MockClass |

# Similarly we plot for other numeric features also. Similarly we can also use a distplot from seaborn library which combines most..

# ###### SOME INFERENCES FROM THE ABOVE HEATMAP
#
# 1. Self relation ie of a feature to itself is equal to 1 as expected.
#
# 2. JobLevel is highly related to Age as expected as aged employees will generally tend to occupy higher positions in the company.
#
# 3. MonthlyIncome is very strongly related to joblevel as expected as senior employees will definately earn more.
#
# 4. PerformanceRating is highly related to PercentSalaryHike which is quite obvious.
#
# 5. Also note that TotalWorkingYears is highly related to JobLevel which is expected as senior employees must have worked for a larger span of time.
#
# 6. YearsWithCurrManager is highly related to YearsAtCompany.
#
# 7. YearsAtCompany is related to YearsInCurrentRole.
#
#
# **Note that we can drop some highly corelated features as they add redundancy to the model but since the corelation is very less in genral let us keep all the features for now. In case of highly corelated features we can use something like Principal Component Analysis(PCA) to reduce our feature space.**

# ## 3 ) Feature Selection
#
# ## 3.1 ) Plotting the Features against the 'Target' variable.
# #### 3.1.1 ) Age
# Note that Age is a continuous quantity and therefore we can plot it against the Attrition using a boxplot.
# In[ ]:
sns.factorplot(data=df,y='Age',x='Attrition',size=5,aspect=1,kind='box')
# Note that the median as well the maximum age of the peole with 'No' attrition is higher than that of the 'Yes' category. This shows that people with higher age have lesser tendency to leave the organisation which makes sense as they may have settled in the organisation.
# #### 3.1.2 ) Department
# Note that both Attrition(Target) as well as the Deaprtment are categorical. In such cases a cross-tabulation is the most reasonable way to analyze the trends; which shows clearly the number of observaftions for each class which makes it easier to analyze the results.
# In[ ]:
df.Department.value_counts()
# In[ ]:
sns.factorplot(data=df,kind='count',x='Attrition',col='Department')
# In[ ]:
pd.crosstab(columns=[df.Attrition],index=[df.Department],margins=True,normalize='index') # set normalize=index to view rowwise %.
# Note that most of the observations corresspond to 'No' as we saw previously also. About 81 % of the people in HR dont want to leave the organisation and only 19 % want to leave. Similar conclusions can be drawn for other departments too from the above cross-tabulation.
# #### 3.1.3 ) Gender
# In[ ]:
pd.crosstab(columns=[df.Attrition],index=[df.Gender],margins=True,normalize='index') # set normalize=index to view rowwise %.
# About 85 % of females want to stay in the organisation while only 15 % want to leave the organisation. All in all 83 % of employees want to be in the organisation with only being 16% wanting to leave the organisation or the company.
# #### 3.1.4 ) Job Level
# In[ ]:
pd.crosstab(columns=[df.Attrition],index=[df.JobLevel],margins=True,normalize='index') # set normalize=index to view rowwise %.
# People in Joblevel 4 have a very high percent for a 'No' and a low percent for a 'Yes'. Similar inferences can be made for other job levels.
# #### 3.1.5 ) Monthly Income
# In[ ]:
sns.factorplot(data=df,kind='bar',x='Attrition',y='MonthlyIncome')
# Note that the average income for 'No' class is quite higher and it is obvious as those earning well will certainly not be willing to exit the organisation. Similarly those employees who are probably not earning well will certainly want to change the company.
# #### 3.1.6 ) Job Satisfaction
# In[ ]:
sns.factorplot(data=df,kind='count',x='Attrition',col='JobSatisfaction')
# In[ ]:
pd.crosstab(columns=[df.Attrition],index=[df.JobSatisfaction],margins=True,normalize='index') # set normalize=index to view rowwise %.
# Note this shows an interesting trend. Note that for higher values of job satisfaction( ie more a person is satisfied with his job) lesser percent of them say a 'Yes' which is quite obvious as highly contented workers will obvioulsy not like to leave the organisation.
# #### 3.1.7 ) Environment Satisfaction
# In[ ]:
pd.crosstab(columns=[df.Attrition],index=[df.EnvironmentSatisfaction],margins=True,normalize='index') # set normalize=index to view rowwise %.
# Again we can notice that the relative percent of 'No' in people with higher grade of environment satisfacftion which is expected.
# #### 3.1.8 ) Job Involvement
# In[ ]:
pd.crosstab(columns=[df.Attrition],index=[df.JobInvolvement],margins=True,normalize='index') # set normalize=index to view rowwise %.
# #### 3.1.9 ) Work Life Balance
# In[ ]:
pd.crosstab(columns=[df.Attrition],index=[df.WorkLifeBalance],margins=True,normalize='index') # set normalize=index to view rowwise %.
# Again we notice a similar trend as people with better work life balance dont want to leave the organisation.
# #### 3.1.10 ) RelationshipSatisfaction
# In[ ]:
pd.crosstab(columns=[df.Attrition],index=[df.RelationshipSatisfaction],margins=True,normalize='index') # set normalize=index to view rowwise %.
# ###### Notice that I have plotted just some of the important features against out 'Target' variable i.e. Attrition in our case. Similarly we can plot other features against the 'Target' variable and analye the trends i.e. how the feature effects the 'Target' variable.
# ## 3.2 ) Feature Selection
# The feature Selection is one of the main steps of the preprocessing phase as the features which we choose directly effects the model performance. While some of the features seem to be less useful in terms of the context; others seem to equally useful. The better features we use the better our model will perform. **After all Garbage in Garbage out;)**.
#
# We can also use the Recusrive Feature Elimination technique (a wrapper method) to choose the desired number of most important features.
# The Recursive Feature Elimination (or RFE) works by recursively removing attributes and building a model on those attributes that remain.
#
# It uses the model accuracy to identify which attributes (and/or combination of attributes) contribute the most to predicting the target attribute.
#
# We can use it directly from the scikit library by importing the RFE module or function provided by the scikit. But note that since it tries different combinations or the subset of features;it is quite computationally expensive and I shall ignore it here.

# ## 4.2 ) Feature Scaling.

scaled_df=scaler.fit_transform(df.drop('Attrition',axis=1))

# <a id="content5"></a>
# ## 5 ) Modelling
#
# ## 5.1 ) Handling the Imbalanced dataset
# Note that we have a imbalanced dataset with majority of observations being of one type ('NO') in our case. In this dataset for example we have about 84 % of observations having 'No' and only 16 % of 'Yes' and hence this is an imbalanced dataset.
#
# To deal with such a imbalanced dataset we have to take certain measures, otherwise the performance of our model can be significantly affected. In this section I have discussed two approaches to curb such datasets.
# ## 5.1.1 ) Oversampling the Minority or Undersampling the Majority Class
#
#
# In an imbalanced dataset the main problem is that the data is highly skewed ie the number of observations of certain class is more than that of the other. Therefore what we do in this approach is to either increase the number of observations corressponding to the minority class (oversampling) or decrease the number of observations for the majority class (undersampling).
#
# Note that in our case the number of observations is already pretty low and so oversampling will be more appropriate.
#
# Below I have used an oversampling technique known as the SMOTE(Synthetic Minority Oversampling Technique) which randomly creates some 'Synthetic' instances of the minority class so that the net observations of both the class get balanced out.
#
# One thing more to take of is to use the SMOTE before the cross validation step; just to ensure that our model does not overfit the data; just as in the case of feature selection.
# In[ ]:
oversampler=SMOTE(random_state=42)
x_train_smote, y_train_smote = oversampler.fit_sample(x_train,y_train)
# ## 5.1.2 ) Using the Right Evaluation Metric
# Another important point while dealing with the imbalanced classes is the choice of right evaluation metrics.
#
# Note that accuracy is not a good choice. This is because since the data is skewed even an algorithm classifying the target as that belonging to the majority class at all times will achieve a very high accuracy.
# For eg if we have 20 observations of one type 980 of another ; a classifier predicting the majority class at all times will also attain a accuracy of 98 % but doesnt convey any useful information.
#
# Hence in these type of cases we may use other metrics such as -->
#
#
# **'Precision'**-- (true positives)/(true positives+false positives)
#
# **'Recall'**-- (true positives)/(true positives+false negatives)
#
# **'F1 Score'**-- The harmonic mean of 'precision' and 'recall'
#
# '**AUC ROC'**-- ROC curve is a plot between 'senstivity' (Recall) and '1-specificity' (Specificity=Precision)
#
# **'Confusion Matrix'**-- Plot the entire confusion matrix
# ## 5.2 ) Building A Model & Making Predictions
# In this section I have used different models from the scikit library and trained them on the previously oversampled data and then used them for the prediction purposes.

'''
You've built an inflight entertainment system with on-demand movie streaming.
Users on longer flights like to start a second movie right when their first one ends,
but they complain that the plane usually lands before they can see the ending.
So you're building a feature for choosing two movies whose total runtimes will
equal the exact flight length.
Write a function that takes an integer flight_length (in minutes) and a list of
integers movie_lengths (in minutes) and returns a boolean indicating whether there
are two numbers in movie_lengths whose sum equals flight_length.
When building your function:
- Assume your users will watch exactly two movies
- Don't make your users watch the same movie twice
- Optimize for runtime over memory
'''

# Build a dictionary by iterating through the array
# Then check every element in the list until one satisfies the requirements

# In this notebook, you will learn how to use the Unity ML-Agents environment for the first project of the [Deep Reinforcement Learning Nanodegree](https://www.udacity.com/course/deep-reinforcement-learning-nanodegree--nd893).
#
# ### 1. Start the Environment
#
# We begin by importing some necessary packages. If the code cell below returns an error, please revisit the project instructions to double-check that you have installed [Unity ML-Agents](https://github.com/Unity-Technologies/ml-agents/blob/master/docs/Installation.md) and [NumPy](http://www.numpy.org/).
from unityagents import UnityEnvironment
import numpy as np
import sys
# Next, we will start the environment! **_Before running the code cell below_**, change the `file_name` parameter to match the location of the Unity environment that you downloaded.
#
# - **Mac**: `"path/to/Banana.app"`
# - **Windows** (x86): `"path/to/Banana_Windows_x86/Banana.exe"`
# - **Windows** (x86_64): `"path/to/Banana_Windows_x86_64/Banana.exe"`
# - **Linux** (x86): `"path/to/Banana_Linux/Banana.x86"`
# - **Linux** (x86_64): `"path/to/Banana_Linux/Banana.x86_64"`
# - **Linux** (x86, headless): `"path/to/Banana_Linux_NoVis/Banana.x86"`
# - **Linux** (x86_64, headless): `"path/to/Banana_Linux_NoVis/Banana.x86_64"`
#
# For instance, if you are using a Mac, then you downloaded `Banana.app`. If this file is in the same folder as the notebook, then the line below should appear as follows:
# ```
# env = UnityEnvironment(file_name="Banana.app")
# ```
env = UnityEnvironment(file_name="Banana.app")
# Environments contain **_brains_** which are responsible for deciding the actions of their associated agents. Here we check for the first brain available, and set it as the default brain we will be controlling from Python.
# get the default brain
brain_name = env.brain_names[0]
brain = env.brains[brain_name]
# ### 2. Examine the State and Action Spaces
#
# The simulation contains a single agent that navigates a large environment. At each time step, it has four actions at its disposal:
# - `0` - walk forward
# - `1` - walk backward
# - `2` - turn left
# - `3` - turn right
#
# The state space has `37` dimensions and contains the agent's velocity, along with ray-based perception of objects around agent's forward direction. A reward of `+1` is provided for collecting a yellow banana, and a reward of `-1` is provided for collecting a blue banana.
#
# Run the code cell below to print some information about the environment.
# +
# reset the environment
env_info = env.reset(train_mode=True)[brain_name]
# number of agents in the environment
print('Number of agents:', len(env_info.agents))
# number of actions
action_size = brain.vector_action_space_size
print('Number of actions:', action_size)
# examine the state space
state = env_info.vector_observations[0]
print('States look like:', state)
state_size = len(state)
print('States have length:', state_size)
# -
# ### 4. It's Your Turn!
#
# Now it's your turn to train your own agent to solve the environment! When training the environment, set `train_mode=True`, so that the line for resetting the environment looks like the following:
# ```python
# env_info = env.reset(train_mode=True)[brain_name]
# ```

This is an old question, and there is lots of stuff written about it on the web,
but all of it is either incorrect or incomplete, so having gotten it to work I
thought it would be good to record my actual working code here.
First, you'll need to create an icon and save it in two formats: Windows "ico"
and Unix "xbm". 64 x 64 is a good size. XBM is a 1-bit format--pixels just on or
off, so no colors, no grays. Linux implementations of tkinter only accept XBM
even though every Linux desktop supports real icons, so you're just out of luck
there. Also, the XBM spec is ambiguous about whether "on" bits represent black or
white, so you may have to invert the XBM for some desktops. Gimp is good for creating these.
Then to put the icon in your titlebar, use this code (Python 3):
