SDUdent telegram bot

This is self learning project aimed to make life of students of my university easier. Bot solves problems that I met during my student life. It has 2 main functionalities:

1. Notify about new grades

   Problem:After passing midterm exams students everytime enters to portal to check, if there is new grade or not

   Solution: Get student's authorization data(student number & password) , parse his/her grades data from portal, save it in database, continuously parse it and check for difference with grades in database,if there is a difference,tell him/her, update grades in database each time .

   Pseudocode:

   while True:
      for user in database.users:
          new_grades = get_grades_from_portal(user['username'],user['password'])
          old_grades = user['semester_data']
          difference = old_grades - new_grades
          if difference:
              notify_user(chat_id = user['chat']
              update_grade_in_database()
   

2. Find sdudent by photo

   Problem: You liked/need someone but don't know his/her name and program,but have a photo?

   Solution: Use pretrained deep-learning model to get feature vector of user photo. User photo can be found in portal .

   This is how our portal looks like,from this page get user's photo,full name,program . Pass user's photo through pretrained model and get feature vector , data(feature_vector,full_name,program) in database.

   

   When another user calls /find_user command and send photo, get feature vector of sent photo and compare with all other user's photo's feature vector by cosine similarity

   

   Pseudocode:

   photo = user.message.photo.get_file()
   current_feature_vector = pretrained_model(photo)
   #shape = [1,512]
   max_sim = 0
   for user in database.users:
        similarity = cos_sim(current_feature_vector,user['feature']
    if max_sum < similarity:
        max_sim = similarity
   
    send message about user with highest similarity
