week13_aws_project

In this project, a chat robot that takes in the user's information and recommends a suitable investment portfolio, is built on Amazon Lex .

Libraries/ library functions

Create an automated investment recommendation application, if the user satisfies certain criteria and based on the user's risk tolerance

A bot 'RoboAdvisor' is created on AWS Lex
Within the above bot, an intent 'RecommendPortfolio' is created
Sample utterances are configured to invoke the intent.
Four slots, 'firstName', 'age', 'investmentAmount' and 'riskLevel' are created to fulfill the intent.
The 'riskLevel' slot is custom defined, that elicits 4 response cards (risk levels).
A confirmation prompt is triggered based on the users response.

To validate the data provided by the user and to recommend an investment strategy based on the risk tolerance, a Lambda function is defined.
The criteria are: Age must be between 0-65 and the investment amount should be at least 5000 USD.
The risk levels are: None, Very Low to Low, Medium, High to Very High
The function is completed, copied to the AWS Lambda and tested with sample test cases.
The test cases with the wrong information gave the expected errors when run on AWS Lambda.

The Lambda function is integrated with the Lex bot and the confirmation prompt on the Lex is removed.
The Lex intent is saved and the bot is built to work with the Lambda function.
The utterances are provided again, and the wrong information in intentionally entered.
The bot threw the expected prompts and hence, proved that the Lambda function was successfully invoked by the Lex.
Upon entering all the information correctly, a suitable investment strategy was recommended

The get_investment_recommendation function was incorrectly defined, at the improper place and the inappropriate value was assigned to be returned.
The Lambda function was not getting invoked by the Lex bot. When the confirmation prompt was removed, the problem was fixed.

I was surprised to find that my work required very little changes/ corrections and I am looking forward to building more complex projects in the future.
