GSOC community bonding week 2: The Paper...s

"Previously on LibreHealth GSOC 2020" [ Recap ]

Kislay had celebrated his selection, told all about it to the friends and family, before he embarked on this journey, like a good traveller he has packed up, while in this context it was updating drivers, installing ubuntu and saying good bye to windows for some time. It was then he understood the quote "I get ideas about what's essential when I'm packing my suitcase" by Diane von Furstenberg. Now:

"Django" [ Gitlab ]

I have created a new django app and setup a free smtp server from send in blue. The django app is capable of authenticating users by sending them email. I have committed all the changes to the forked repo. Since the plan is to use Reactjs frontend so I have used Django-rest-framework. For authentication I have used rest-auth. "awesome library"

The steps to setup your own rest authentication service using Django:

Install django rest auth and allauth:

pip install django-rest-auth[with_social]

pip install django-allauth

Signup with a smtp service provider and get the credentials.

Modify your settings.py

First the installed apps:

INSTALLED_APPS = [
...
'rest_framework.authtoken',
'rest_auth',
'django.contrib.sites',
'allauth',
'allauth.account',
'rest_auth.registration',
'allauth.socialaccount'
...
]

SMTP server keys:

EMAIL_HOST = 'smtp-relay.sendinblue.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_USE_SSL = False
EMAIL_HOST_USER = 'singh.kislay.kunal@gmail.com'
EMAIL_HOST_PASSWORD = os.environ.get('EMAIL_HOST_PASSWORD')

Modify your urls.py

url_pattern = [
...
re_path(r'^rest-auth/registration/account-email-verification-sent/', views.null_view, name='account_email_verification_sent'),
    re_path(r'^rest-auth/registration/account-confirm-email/(?P<key>[-:\w]+)/$', ConfirmEmailView.as_view(), name='account_confirm_email'),
    re_path(r'^rest-auth/registration/complete/$', views.complete_view, name='account_confirm_complete'),
    re_path(r'^password-reset/confirm/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$', views.null_view, name='password_reset_confirm'),
    re_path(r'rest-auth/', include('rest_auth.urls')),
    re_path(r'^rest-auth/registration/', include('rest_auth.registration.urls'))
...
]

 Easy, you have your authentication server setup. Don't forget to make the migrations.

"Paper...s" [ Reading ]
There were several papers that were mentioned to be read and one of them a had a public code repo, so can you guess which paper I started with? I started with "Deep Neural Networks Improve Radiologists’Performance in Breast Cancer Screening" This is simply a beautiful paper, the idea of getting heat maps by sliding window over 224*224 chunks of image and then sending these heat maps directly in to a different neural nework that accepts 4 images, each image being the image(grayscale), heatmap of  the malign and heatmap of the benign area for making 3 channels is amazing. mind == blown. I loved reading the paper, right now I'm working on porting there code to tensorflow 2.1 as it is in tensorflow 1.13. Why you ask? well, new is always better.

"Next week" [ Plan ]
Port the model to tf 2.1. I have never ported a tf script to a different versions, this will be new and fun. Right now I just feel like I can do it.
