Dear Dr. Ting,

I trust this email finds you well.

I am writing to seek clarification regarding the requirements for preparing our presentation file for the upcoming assignment.

I have added narration to each slide, which can be played separately for each one.

I would like to confirm whether providing the presentation solely in .pptx format in this way meets the assignment criteria.

I have attached a screenshot exemplifying the layout of one of the slides for your reference.

Your guidance on these matters would be greatly appreciated to ensure that our presentation aligns perfectly with the project objectives.

Thank you for your attention to this matter.

Hello Ting,

I am writing to seek your guidance regarding the Artificial Intelligence and Machine Learning assignment. Upon examination of the assignment brief, I encountered some uncertainty about how we are expected to utilize the sample data provided. Could you please clarify whether the use of the provided dataset is a requirement for this assignment? Furthermore, any additional examples or explanation on how to apply this data would be highly appreciated. Such guidance would greatly aid in deepening my understanding and ensure that  my approach aligns with the expected outcomes.

Hello Tao,

Good day to you and compliment of the season. I wish to know if I can make use of Power BI for my assessment analysis. I look forward to hearing from you soon. Thank you

Dear Dr Ting and Dr. Abiola,

I hope this email finds you well.

Upon reviewing the assignment, I have encountered certain areas where I require clarification. 

Firstly, I am seeking confirmation on whether we are permitted to utilize the Machine Learning module available in the cloud version of Alteryx. My exploration indicates its availability, but I wish to ensure its appropriateness for our task.

Additionally, regarding the dataset for customer churn analysis, I have examined the sample data provided and found it to have only a few null values, primarily in the "Total charge" variable, while overall maintaining cleanliness. In my presentation, may I assert the importance of data validation and mention that I replaced the rows with null "Total charge" values with the mean? Furthermore, may I state that our dataset requires no other modifications?

Furthermore, while assessing the correlation among variables, I observed strong correlations between certain pairs. However, upon removing one variable from the model, I noted a decrease in model accuracy. Would it be acceptable to elaborate on this observation, concluding that despite the strong correlation, retaining the variable in the model is imperative for maintaining accuracy?

I have attached two photos illustrating my concerns.

Your guidance in these matters would be greatly appreciated.

Thank you for your attention to this matter.

Warm regards,

Dear Dr. Ting Wu,

I appreciate your previous clarification on the matter.

I am writing to seek further guidance regarding the functionality of the cloud version of Alteryx. Specifically, after applying a selected algorithm to the dataset, it seems that we are restricted in our ability to import another dataset, such as data for a specific period to be predicted. Instead, the platform offers a simulation feature wherein we can select a specific row from the dataset to obtain an initial predicted result. Subsequently, we have the capability to adjust the parameters of the selected model and observe the resulting changes based on the new parameters for that specific row, effectively conducting a "What if" analysis.

My query pertains to whether conducting this "What if" analysis alone would suffice for analyzing the model's performance and its output, or if it is necessary to provide a predicted set of data post-model application. It is important to note that the cloud version of Alteryx does not support the latter approach.

I would greatly appreciate your insights and guidance on this matter. 

Warm regards,

Hi,

I hope you had a great weekend.

I need clarification on the assignment for Business Analytics class. Which part of the result from the tool use in our analysis should be included on the PowerPoint? Is it the list of Yes/No, the bar chart, etc. I just want to know the kind of result to be included in the slides.

Thank you.

Regards,
