Telco_5G_QOE_Analysis_SQL Improvements

[DougEbel]

I was using this to validate execution in Lake. As a byproduct, I identified markdown changes that would make it clearer:

1. In 4.1 (and later steps), there are multiple comments/table names indicating that a graph is being produced, but no graph is produced until the step "select * from barGraph". We should say how we are accumulating data and add a comment to the select "Finally, display the barGraph.
2. The comment Click on the cell in the IMAGE column to select it, then right click on the cell and select View Image. ... should add that they can use shift-mouse roll to increase the size of the graph (so they can read it)
3. I'd repeat (parenthetically) the meaning of CQI and RSRP to help the user ... hold it ... We didn't define those metric anywhere
4. No interpretation of the "Number of Ids in each QoE cluster" chart
5. For Data preparation, the comment is "Before we can use the data in models we will perform some data preparation steps." ... What models and what do the models help us do to identify improvement opportunities
6. For "Number of Ids in each QoE Cluster" graph, no conclusions of what the graph shows.
7. No conclusions to "Number of Ids in each QoE Cluster in Test data by Decision Forest Model" ... what is the business impact? ... same for the XGB graph
8. was running demo on Lake using PC Docker, but ran the requirements.txt used to provision CSAE environments. Got error that seems familiar:
   Unable to run SQL: Unable to run SQL query: Database reported error:7810:Error in function TD_GLM: Invalid input alias encountered. Please refer user guide.
