evaluation | A custom Rouge wrapper for summary evaluation | Natural Language Processing library

I am trying to use my own train step in with Keras by creating a class that inherits from Model. It seems that the training works correctly but the evaluate function always returns 0 on the loss even if I send to it the train data, which have a big loss value during the training. I can't share my code but was able to reproduce using the example form the Keras api in https://keras.io/guides/customizing_what_happens_in_fit/ I changed the Dense layer to have 2 units instead of one, and made its activation to sigmoid.

The code:

I am crunching large amounts of data without a hitch until I added more data. The results are written to file as strings, but I received this error message and I am unable to find programming error after combing my codes for 2 days; my codes have been working fine before new data were added.

I am trying to sort the values of my columns depending on the date (d/m/y + hour: min: sec). Below I will show you an example of the format of the given data:

I can compile it. However, when I input my date and time I get the error. Below is the code in question regarding this issue. error code: TypeError: '<=' not supported between instances of 'Timestamp' and 'str'.

I developed an app using rshiny, https://smandape.shinyapps.io/mmdit/. I am trying to make it WCAG 2.1 accessible. I am using WAVE (Web accessibility evaluation tool) to check for accessibility. Currently, the errors popping are related to 'missing form label'. These errors are specifically for the code fileInput or rabiobuttons (5 errors are on Data import tab). For example, around the following code. WAVE shows the error for the placeholder for fileInput.

• As of Shiny 1.5.0, we are encouraged to use moduleServer rather than callModule.
• However, it appears as though we can't pass additional parameters to moduleServer (unlike callModule).
• This is an issue because I'd like to pass the parent session as a parameter to moduleServer, so that I can correctly reference the parent session in order for updateTabsetPanel to work correctly inside a renderUI dynamic output.

This post demonstrates how to use callModule to pass the parent session into the module so that updateTabsetPanel can reference the parent session and update it accordingly. I used that approach to create a minimal example here. There are two tabPanels, and we are trying to navigate to the second via an actionLink in the first. The first_server module is called with callModule, and we are able to pass the parent session parameter as an additional argument, allowing us to reference it in the updateTabsetPanel call in first_server. Clicking the actionLink then takes us to the second module UI, as expected:

I wanted a ArrayFormula at C1 which gives the required result as shown.

Entry sheet:
(Column C is my required column)

Date Entered is the date when the Name is Assigned a group i.e. a, b, c, d, e, f

Criteria:

1. The value of count is purely on basis of Date Entered (if john is assigned a on lowest date(10-Jun) then count value is 1, if rose is assigned a on 2nd lowest date(17-Jun) then count value is 2).
2. The value of count does not change even when the data is sorted in any manner because Date Entered column values is always permanent & does not change.
3. New entry date could be any date not necessarily highest date (If a new entry with name Rydu is assigned a on 9-Jun then the it's count value will become 1, then john's (10-Jun) will become 2 and so on)

Example:

After I sort the data in any random order say like this:

Random ordered sheet:
(Count value remains permanent)

And when I do New entries in between (Row 4th & 14th) and after last row (Row 17th):

Random Ordered sheet:
(Doesn't matter where I do)

1. ={"AF Formula1"; ArrayFormula(IF(B2:B="", "", COUNTIFS(B$2:B, "="&B2:B, D$2:D, <"&D2:D)+1))}
2. ={"AF Formula2";INDEX(IFERROR(1/(1/COUNTIFS(B2:B, B2:B, ROW(B2:B), "<="&ROW(B2:B)))))}

I tried to figure my own ArrayFormula but it's not working:

I got Formula for each cell:
=RANK($D2,FILTER($D$2:$D, $B$2:$B=$B2),1)
I figured out Filter doesn't work with ArrayFormula so I had to take a different approach.

I took help from my previous question answer (Arrayformula at H3) which was similar since in both cases each cell FILTER formula returns more than 1 value. (It was actually answered by player0)

Using the same technique I came up with this Formula which works absolutely fine :

=RANK($D2, ARRAYFORMULA(TRANSPOSE(SPLIT(VLOOKUP($B2, SUBSTITUTE(TRIM(SPLIT(FLATTEN(QUERY(QUERY({$B:$B&"×", $D:$D}, "SELECT MAX(Col2) WHERE Col2 IS NOT NULL GROUP BY Col2 PIVOT Col1", 1),, 9^9)), "×")), " ", ","), 2, 0), ","))), 1)

Now when I tried converting it to ArrayFormula: ($D2 to $D2:$D & $B2 to $B2:$B)

=ARRAYFORMULA(RANK($D2:$D,TRANSPOSE(SPLIT(VLOOKUP($B2:$B, SUBSTITUTE(TRIM(SPLIT(FLATTEN(QUERY(QUERY({$B:$B&"×", $D:$D}, "SELECT MAX(Col2) WHERE Col2 IS NOT NULL GROUP BY Col2 PIVOT Col1", 1),, 9^9)), "×")), " ", ","), 2, 0), ",")), 1))

It gives me an error "Did not find value '' in VLOOKUP evaluation", I figured out that the problem is only in VLOOKUP when I change $B2 to $B2:$B.

I'm sure VLOOKUP works with ArrayFormula, I fail to understand where my formula is going wrong! Please help me correct my ArrayFormula.

Here is the editable sheet link

I would like to know if it is possible to automatically assign values ​​to added fields of type:

• datetime
• entity

Thanks for your help

I'm trying to get Alpha-beta pruning to work but it's giving me completely wrong moves compared to my Minimax function. Here is my Minimax function which is working perfectly right now.
