AWS + Linear Regression

Tasks:

  • Defining the activity in the stream (pipeline):
  • Determining the value of a new attribute based on others
  • Filtering/add other attributes

Locally:

  • Define an MQTT client that saves data to a csv file
  • Write a script that generates a plot of values against time
  • Determine the mean value, standard deviation
  • Use at least one ML method

Useful commands:

 pip install uvicorn
 
 pip3 install fastapi
 
 /home/pi/.local/bin/uvicorn script:app --reload
 
 pip install paho-mqtt
 
 apt-get install mosquitto
 
 apt-get install mosquitto-client
 
 ps -ef | grep mosquitto
