💻 Machine Learning Algorithms

Machine Learning using Python

ML Algorithms

1. K-Nearest Neighbours Algorithm
2. Linear Regression in one variable
3. Linear Regression with multiple variables

Installation

1. Make sure python3 and git is installed. Install Python : From official website

Additional instructions

Install Python :

From official website

To check version of Python :

py --version
python --version

Create a virtual environment :

py -m venv blog_app

To activate virtual-environment :

.\Scripts\activate

To deactivate virtual-environment :

.\Scripts\deactivate

To check python is used in virtualenv :

pip -V

If you are running the virtual env, it'll show the path to the environment's location.

To install a package in virtual environment :

py -m pip install package_name

To install django :

py -m pip install django
django --version

To check django version :

py -m django --version

To start a new app :

python manage.py startapp your_app_name

Then make an entry for the app in the INSTALLED_APPS section in settings.py Include URL's of your new app using include() in url.py (main app)

While activating if terminal shows, "running scripts is disabled on this system"

There are 4 policy levels to choose from. From most secure to most insecure:

1. Restricted: No Powershell scripts can be run. This is the default setting.

2. AllSigned: Scripts can be run, but all must have a digital signature. Even if you wrote the script yourself on the local computer.

3. RemoteSigned: Locally-written scripts can be run. But scripts from outside (email, IM, Internet) must be signed by a trusted publisher.

4. Unrestricted: Any script will run. Regardless of who created them or whether they are signed.

   To view the current systemwide Execution Policy setting :

   Get-ExecutionPolicy

   To set execution policy :

   Set-ExecutionPolicy remotesigned

Touch alternative in windows powershell :

$null > file_name.cpp

Configure GIT :

git config --global user.email "user_mail"
git config --global user.name "user_name"

NOTE: Make .gitignore file after initialising the GIT repository

To run the application server :

python manage.py runserver

For migrating the models to the database :

python manage.py makemigrations
python manage.py migrate

While making a POST request through a form to the server, include :

{% csrf_token %}

To checkout a particular branch:

git checkout <branch-name>

To list all the branches in the git repository:

git branch -a

To lists all the modules installed for the project:

py -m pip freeze
py -m pip list

To merge a branch into master branch:

Change to master branch

git checkout master
git merge <branch-name>

To see branch graphs in git:

git log --graph --oneline --decorate --all

To see all remotes

git remote -v

To push all branches to remote repository

git push --all <remote-origin>

To add a new remote to push changes to

git remote add new-remote-origin-name https://github.com/user_name/repo.git

If you happen to delete db.sqlite3 file, run:

python manage.py migrate
