The case of one explanatory variable is called simple linear regression. + +.. image:: images/9.png + +Linear regression is the next step up after correlation. It is used when we want to predict the value of a variable based on the value of another variable. The variable we want to predict is called the dependent variable (or sometimes, the outcome variable). Linear regression consists of finding the best-fitting straight line through the points. The best-fitting line is called a regression line. + +Evaluation +---------- +Since we are attempting to perform regression which outputs continuous value within a given range. Our main goal is to minimize the error which is defined by the Loss Function. + +We have chosen average lifespan as our baseline. We compare our other features with this baseline by plotting graphs and using Mean Absolute Error (MAE) as a metric to evaluate the results of the prediction.

Dataset

+

The dataset is provided as part of the MSR 2020 challenge. +The full version spans more than 5 billion unique source code files and 1 billion unique commits, +coming from more than 80 million software projects. Contents come from GitHub and GitLab, FOSS distributions +like Debian, and language-specific package managers like PyPI. +The data is stored in a uniform representation: A Merkle DAG linking source code +files in directories, evolution of commits and snapshots of +the VCS.

+
+

Welcome to MSR Project!

+

The International Conference on Mining Software Repositories (MSR) has hosted the mining challenge every year, since 2006. +With this challenge, they aim at everyone interested to apply their tools to a common dataset. +The challenge is for researchers and practitioners to use their mining tools and approaches on a dare. +The goal is to answer questions about a given dataset, that were previously unanswered.

+

MSR 2020 is a challenge which presents Software Heritage Graph Dataset. +This is one of the largest known existing public archive of software source code and accompanying development history. +More information can be found in ‘Dataset’ tab.

+

Our goal here is to answer certain research questions (mentioned in ‘Problem Statement’ tab) and gain some meaninful insights from the dataset.

Model

+
+

High Level Design

+_images/10.PNG +

As for a high level idea, we start off by preprocessing our data, which includes sampling, labelling, cleaning and splitting it into train and test data. We the use a linear regression approach to model our dataset and get the output. This is further evaluated by metrics such as Mean Absolute Error as explained below.

+
+
+

Linear Regression

+

Linear regression is a linear approach to modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression.

+_images/9.png +

Linear regression is the next step up after correlation. It is used when we want to predict the value of a variable based on the value of another variable. The variable we want to predict is called the dependent variable (or sometimes, the outcome variable). Linear regression consists of finding the best-fitting straight line through the points. The best-fitting line is called a regression line.

+
+
+

Evaluation

+

Since we are attempting to perform regression which outputs continuous value within a given range. Our main goal is to minimize the error which is defined by the Loss Function.

+

We have chosen average lifespan as our baseline. We compare our other features with this baseline by plotting graphs and using Mean Absolute Error (MAE) as a metric to evaluate the results of the prediction. MAE is the sum of absolute distances between our target variable and predicted values.

+

Mathematically, it can be expressed as follows:

+
+\[\frac{ \sum_{i=1}^{N}|y_i - x_i| }{N}\]
+

where +\(y_i\) +is the predicted value from the regression model, +\(x_i\) +is the true value of the datapoint and +N is the number of datapoints.

    • +
+
+
+

Getting Started

+

In the main repository, there exists a python file called main.py.

+

Create a database.ini file and store your config there. The config must include the following:

+
[postgresql]
+host=<host-name>
+port=<port-number>
+database=<database-name>
+user=<user-name>
+password=<password>
+
+
+

Go to terminal or any IDE and run that file using the following command:

Problem Statement

+

We are trying to answer the following research question -

+

What is the predicted lifespan of a repository, given the github dataset?

+
+

Motivation

+

Big organizations spend a lot of resources and money for hosting their code repositories. +If they have a large amount unused repositories, in terms of volume, it will be a financial overhead on them. +So, using our solution, they can easily look for the unused repositories and remove them appropriately. +This will save them the resources which can be better utilised in something else.

Results

+

Regression is a statistical method to determine the relationship of one variable dependent on others. For our project, We take the average lifespan of a repository as our baseline. Using this baseline, We have evaluated the model using the MAE metric. Our model has performed better than the baseline as shown below.

+
Error by Baseline : 348.8 (~349 days)
+Error by Model : 288.7 days (~289 days)
+
+
+

We have plotted graphs comparing the lifespan to the various features such as total number of snapshot counts, number of targets, original date, number of revisions, number of releases and last revision date. Each diagram shows three scatter plots : The actual value obtained from the table, the value predicted by the model and the average lifespan value which is our baseline.

+

According to our graphs, We infer that the lifespan feature does not heavily depend on the values of the other features individually. Even though the number of snapshots are the same, the lifespan values differ showing that the snapshot count does not matter. However, A combination of these features will affect the lifespan value which means the combination of features does matter. This is proved by the fact that our model obtained a lower error rate than the baseline.

As part of this project, I worked on the implementing Seldonian algorithm for fairness in machine learning for any generic constraint.

We the use a linear regression approach to model our dataset and get the output. This is further evaluated by metrics such as Mean Absolute Error as explained below. + +Linear Regression +----------------- +Linear regression is a linear approach to modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression. + +.. image:: images/9.png + +Linear regression is the next step up after correlation. It is used when we want to predict the value of a variable based on the value of another variable. The variable we want to predict is called the dependent variable (or sometimes, the outcome variable). Linear regression consists of finding the best-fitting straight line through the points. The best-fitting line is called a regression line. + +Evaluation +---------- +Since we are attempting to perform regression which outputs continuous value within a given range. Our main goal is to minimize the error which is defined by the Loss Function. + +We have chosen average lifespan as our baseline. We compare our other features with this baseline by plotting graphs and using Mean Absolute Error (MAE) as a metric to evaluate the results of the prediction. MAE is the sum of absolute distances between our target variable and predicted values. + +Mathematically, it can be expressed as follows: + +.. math:: + + \frac{ \sum_{i=1}^{N}|y_i - x_i| }{N} + +where +:math:`y_i` +is the predicted value from the regression model, +:math:`x_i` +is the true value of the datapoint and +N is the number of datapoints. + + diff --git a/sphinx/_build/html/_sources/pre_req.rst.txt b/sphinx/_build/html/_sources/pre_req.rst.txt new file mode 100644 index 0000000..b2ea735 --- /dev/null +++ b/sphinx/_build/html/_sources/pre_req.rst.txt @@ -0,0 +1,56 @@ +Quick Start +=========== + +This page is intended to be a user guide for the developers to quickly +be able to use/re-use the codebase for their own project +or, extending/enhancing the codebase for better performing models. + +Pre-requisities +--------------- + +Knowledge pre-requisites + +* Python: The code is written in Python and thus, some prior knowledge of Python programming is useful. + +* PostGres: The database format of MSR2020 is postgres and hence, familiarity of postgresql is essential for getting started with this project. + +Library pre-requisites + +* psycopg2 - postgres and python connection adapter library to access the database. + +* sklearn - machine learning model implementations like linear regression. + +* matplotlib - visualizations of the plots. + +* sphinx and sphinx-rtd-theme - Python auto-documentation generator. + +* PyCharm - or, any other IDE to edit the code. + +Getting Started +--------------- + +In the main repository, there exists a python file called `main.py`. + +Create a `database.ini` file and store your config there.

Dataset

+

The dataset is provided as part of the MSR 2020 challenge. +The full version spans more than 5 billion unique source code files and 1 billion unique commits, +coming from more than 80 million software projects. Contents come from GitHub and GitLab, FOSS distributions +like Debian, and language-specific package managers like PyPI. +The data is stored in a uniform representation: A Merkle DAG linking source code +files in directories, evolution of commits and snapshots of +the VCS.

+
+

Complete Dataset

+

The Software Heritage Graph Dataset contains a table representation of the full Software Heritage Graph. It is available in the following formats:

+
    +

  1. PostgreSQL (compressed):

    +
    +
      +

    • Total size: 1.2 TiB

      • +

    • URL: /graph/latest/sql/

Teaser Dataset

+

The above dataset is too big, so following ‘teaser’ dataset is mainly used for training and testing purposes in our implementation.

+
+ + +
+

Relational Schema

+

The Merkle DAG of the Software Heritage archive is encoded in the dataset as a set of relational tables. A simplified view of the corresponding database schema is shown here:

With the growing usage of machine learning and artificial intelligence in real lives, +the need for incorporating mitigation of unethical and unmoral issues in machine learning +models is rising at an alarming rate. +This requires us to develop a tool to evaluate and mitigate unfairness in these models +that would help data scientists in dealing with unfairness in the models they develop. +Seldonian algorithm is a framework that tackles the problem of regulating the +undesirable behavior of machine learning algorithms on various real world data and transfers the responsibility of the machine learning to be `fair’ or `safe’ from user of the algorithm to designer of the algorithm (i.e. at the creation step itself by ML researcher). As part of this project, I worked on the implementing Seldonian algorithm for fairness in machine learning for any generic constraint. In addition, I experimented towards its extensions in terms of optimizing the bounds, making it more efficient.

Model

+
+

High Level Design

+_images/10.PNG +

As for a high level idea, we start off by preprocessing our data, which includes sampling, labelling, cleaning and splitting it into train and test data. We the use a linear regression approach to model our dataset and get the output. This is further evaluated by metrics such as Mean Absolute Error as explained below.

+
+
+

Linear Regression

+

Linear regression is a linear approach to modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression.

+_images/9.png +

Linear regression is the next step up after correlation. It is used when we want to predict the value of a variable based on the value of another variable. The variable we want to predict is called the dependent variable (or sometimes, the outcome variable). Linear regression consists of finding the best-fitting straight line through the points. The best-fitting line is called a regression line.

+
+
+

Evaluation

+

Since we are attempting to perform regression which outputs continuous value within a given range. Our main goal is to minimize the error which is defined by the Loss Function.

+

We have chosen average lifespan as our baseline. We compare our other features with this baseline by plotting graphs and using Mean Absolute Error (MAE) as a metric to evaluate the results of the prediction. MAE is the sum of absolute distances between our target variable and predicted values.

+

Mathematically, it can be expressed as follows:

+
+\[\frac{ \sum_{i=1}^{N}|y_i - x_i| }{N}\]
+

where +\(y_i\) +is the predicted value from the regression model, +\(x_i\) +is the true value of the datapoint and +N is the number of datapoints.

+
+

Pre-requisities

+

Knowledge pre-requisites

+
    +

  • Python: The code is written in Python and thus, some prior knowledge of Python programming is useful.

    • +

  • PostGres: The database format of MSR2020 is postgres and hence, familiarity of postgresql is essential for getting started with this project.

    • +
+

Library pre-requisites

+
    +

  • psycopg2 - postgres and python connection adapter library to access the database.

    • +

  • sklearn - machine learning model implementations like linear regression.

    • +

Problem Statement

+

We are trying to answer the following research question -

+

What is the predicted lifespan of a repository, given the github dataset?

+
+

Motivation

+

Big organizations spend a lot of resources and money for hosting their code repositories. +If they have a large amount unused repositories, in terms of volume, it will be a financial overhead on them. +So, using our solution, they can easily look for the unused repositories and remove them appropriately. +This will save them the resources which can be better utilised in something else.

Results

+

Regression is a statistical method to determine the relationship of one variable dependent on others. For our project, We take the average lifespan of a repository as our baseline. Using this baseline, We have evaluated the model using the MAE metric. Our model has performed better than the baseline as shown below.

+
Error by Baseline : 348.8 (~349 days)
+Error by Model : 288.7 days (~289 days)
+
+
+

We have plotted graphs comparing the lifespan to the various features such as total number of snapshot counts, number of targets, original date, number of revisions, number of releases and last revision date. Each diagram shows three scatter plots : The actual value obtained from the table, the value predicted by the model and the average lifespan value which is our baseline.

+

According to our graphs, We infer that the lifespan feature does not heavily depend on the values of the other features individually. Even though the number of snapshots are the same, the lifespan values differ showing that the snapshot count does not matter. However, A combination of these features will affect the lifespan value which means the combination of features does matter. This is proved by the fact that our model obtained a lower error rate than the baseline.
