C4 W1, diff_moving_avg_plus_smooth_past

[Akbar167]

I am currently working on Exercise 8 involving smooth_past_series and facing some issues. Below is the code snippet and the output I obtained:
Posting codes correct or incorrect, sharing links to graded assignment, sharing notebook assignment is against community guidelines. kindly refer Code of Conduct and How to Use the Forum for better understanding of community guidelines

Output I Got:

Failed test case: diff_moving_avg_plus_smooth_past has incorrect first 5 values.
Expected: [55.13228 54.10422 53.275375 52.182724 51.436935]
Got: [48.96211 52.344227 55.13228 54.10422 53.275375]

Failed test case: diff_moving_avg_plus_smooth_past has incorrect last 5 values.
Expected: [28.81515 31.856792 35.53977 39.16417 42.837337]
Got: [21.733616 25.267376 28.81515 31.856792 35.53977 ]

How can I adjust my implementation to get the diff_moving_avg_plus_smooth_past output that matches the expected results?

did you ever get this sorted? I also have this issue;

exercise 8 smooth_past_series of C4W1_assignment (in course: Sequences, Time Series and Prediction)
is not returning the required values.

How did you proceed? I found myself just guessing the correct split of SERIES , without success. Many thanks

the below post might help you debug your codes

hi @edmos7 When you do now correction please make sure to get a fresh copy of assignment and only write codes between assigned markers ###START AND END CODE HERE### and making sure not to delete the already given instructions and do not add your own way of writing the codes. You suppose to only replace None placed between the Markers ###START AND END CODE HERE### without editing the already given instructions or part of codes already given to you when you first open the assignment notebook.

Cheers Deepti, that helped all right and i got the solution… But i dont understand it so a query please…

I have the following values…

length of series: 1461
SPLIT_TIME: 1100
WINDOWS_SIZE: 11
period = 365

Where does the number 370 come from??
Where does the number 359 come from??

Many thanks in advance.

hi @Cormac_Garvey

this should explain your question

Sequences, Time Series and Prediction: C4W1

Hi @fatihah You also needed to move your query to the right section by using the edit pen option, for now I have moved it to the right category for response from the course mentors. the split time is 370 as the slicing is related to the series (i.e. period and noise level of 5) and not only period. If you check the generate synthetic data, the forecast is a seasonal trend of 365 steps but some noise is added as the real world data often has some noise. In numerical analysis, noise is genera…

Let me know if you still have any doubts.
