I'm currently working an a very simple project management template.
The Idea is that after entering a start and end-date columns will show up as a very simplistic gantt chart (conditional formating).
Everything works fine, until "year" comes into consideration. Since it is a several years lasting project and we work with calenderweeks it is essential that the work package is only visualized in its specific year.
So I came up with the following (rough'n'dirty) formular (example from cell K3):
=and(if(K$2>=$F3;1;0);if(K$2<=$H3;1;0);if(or(right($E3;4)=K$1;1);(right(G3;4)=K1;1;0)))
This is the document: https://docs.google.com/spreadsheets/d/15F1uBnoHMuJqc_w0X04U5-ZCQ_6mgO_HJqvN5U28cog/edit?usp=sharing
Problem: GoogleSpreadsheets only alows three arguments with IF. But I do not know how to structure it otherwise...
Thankful for any suggestion!
Cheers,
Matt
This might be what you are looking for, ties the start week/ end week and year together for comparison.
=IF(AND(
(K$1&TEXT(K$2;"00")) >=(RIGHT($E$3;4)&TEXT($F$3;"00"));
(K$1&TEXT(K$2;"00")) <=(RIGHT($G$3;4)&TEXT($H$3;"00")))
;1;0)

I am trying to specify a time that starts a shift premium for a time card. I was so happy I finally figured out how to get it, but then I changed a time to a first shift time and thats when I lost all hope. I have spent hours messing with this and my current formula's looks like
x1.05
=IF(COUNT(A20:B20)=2,MOD($B$18-A20,1)*24,"")
x1.1
=IF(COUNT(A20:B20)=2,MOD(B20-$B$18,1)*24,"")
My end goal is to have it so first shift (7am - 3pm) fall under base pay, 2nd shift (4pm-12am) fall under x1.05 and anything past 12am falls under x1.1
Just getting this far has been a mind blower for me and any help would be greatly appreciated.
I have moved this to its own sheet to share with everyone. I am still playing with things myself and trying different things, but on the sheet I have included the variables along with the wording of the contract that effects the pay scale. NOTE the times I originally provided were just examples from the top of my head.
My Sheet
It doesn't look like your current sheet accounts for the multiple criteria you're wanting to evaluate. First shift (x1) begins at 7; second shift (x1.05) begins at 15:00, and third shift (x1.10) begins at 24:00.
I added each of those directly above the columns they affect and used this formula for the Base column:
=IF(COUNT($A20:$B20)=2,IF($A20<F$18,(MOD(MIN(F$18,$B20)-$A20,1))*24,0),"")
...this for the x1.05 column:
=IF(COUNT($A20:$B20)=2,IF($A20<G$18,(MOD(MIN(G$18,$B20)-$A20,1)*24)-E20,0),"")
...and this for the x1.10 column:
=IF(COUNT($A20:$B20)=2,(MOD(MIN(E$18+1,$B20)-$A20,1)*24)-SUM(E20:F20),"")
So far, it's working as expected. One thing I didn't add into it is to account for someone who starts their shift before 7 a.m. If you want this to be included in the x1.10 column, you could add a calculation for that to the formula there.
Here's what it looks like:
I'm working in Excel, but these formulas should all work in Google Sheets as well.
I have asked a few questions related to this personal project of mine already on this platform, and this should be the last one since I am so close to finishing. Below is the link to a mock example spreadsheet I've created, which mimics what my actual project does but it contains less sensitive information and is also smaller in size.
Mock Spreadsheet
Basic rundown of the spreadsheet:
Pulls data from a master schedule which is controlled/edited by another party into the Master Schedule tab.
In the columns adjacent to the imported data, an array formula expands the master schedule by classroom in case some of the time slots designate multiple rooms. Additional formulas adjust the date, start time, and end time to be capped within the current day's 24-hour period. The start time of each class is also made to be an hour earlier.
In the Room Schedule tab, an hourly calendar is created based on the room number in the first column, and only corresponds to the current day.
I have tested the spreadsheet extensively with multiple scenarios, and I'm happy with how everything works except for the calculation time. I figured the two volatile functions I use would take some processing time just by themselves, and I certainly didn't expect this to be lightning-fast especially without using a script, but the project that I am actually implementing this method for is much larger and takes a very long time to update. The purpose of this spreadsheet is to allow users to find an open room and "reserve" it by clicking the checkbox next to it (which will consequently color the entire row red) allowing everyone else to know that it is now taken.
I'd like to know if there is any way to optimize / speed up my spreadsheet, or to not update it every time a checkbox is clicked and instead update it "manually", similar to what OP is asking here. I am not familiar with Apps Script nor am I well-versed in writing code overall, but I am willing to learn - I just need a push in the right direction since I am going into this blind. I know the number of formulas in the Room Schedule tab is probably working against me yet I am so close to what I wanted the final product to be, so any help or insight is greatly appreciated!
Feel free to ask any questions if I didn't explain this well enough.
to speed up things you should avoid usage of the same formulae per each row and make use of arrayformulas. for example:
=IF(AND(TEXT(K3,"m/d")<>$A$1,(M3-L3)<0),K3+1,K3+0)
=ARRAYFORMULA(IF(K3:K<>"",
IF((TEXT(K3:K, "m/d")<>$A$1)*((M3:M-L3:L)<0), K3:K+1, K3:K+0), ))
=IF(AND(TEXT(K3,"m/d")=$A$1,(M3-L3)<0),TIMEVALUE("11:59:59 PM"),M3+0)
=ARRAYFORMULA(IF(K3:K<>"",
IF((TEXT(K3,"m/d")=$A$1)*((M3-L3)<0), TIMEVALUE("11:59:59 PM"), M3:M+0), ))
I've set up a Google Sheets workbook that synthesizes data from a few different sources via manual input, IMPORTHTML and IMPORTRANGE. Once the data is populated, I'm using INDEX MATCH to filter and compare the information and to RANK each data set.
Since I have multiple data inputs, I'm running into a persistent issue of names not being written exactly the same between sources, even though they're the same person. First names are the primary culprit (i.e. Mary Lou vs Marylou vs Mary-Lou vs Mary Louise) but some last names with special symbols (umlauts, accents, tildes) are also causing errors. When Sheets can't recognize a match, the INDEX MATCH and RANK functions both break down.
I'm wondering how to better unify the data automatically so my Sheet understands that each occurrence is actually the same person (or "value").
Since you can't edit the results of an IMPORTHTML directly, I've set up "helper columns" and used functions like TRIM and SPLIT to try and fix instances as I go, but it seems like there must be a simpler path.
It feels like IFS could work but I can't figure how to integrate it. Also thinking this may require a script, which I'm just beginning to study.
Here's a simplified example of what I'm trying to achieve and the corresponding errors: Sample Spreadsheet
The first tab is attempting to pull and RANK data from tabs 2 and 3. Sample formulas from the Summary tab, row 3 (Amelia Rose):
Cell B3: =INDEX('Q1 Sales'!B:B, MATCH(A3,'Q1 Sales'!A:A,0))
Cell C3: =RANK(B3,$B$2:B,1)
Cell D3: =INDEX('Q2 Sales'!B:B, MATCH(A3,'Q2 Sales'!A:A,0))
Cell E3: =RANK(D3,$D$2:D,1)
I'd be grateful for any insight on how to best index 'Q2Sales'!B3 as the correct value for 'Summary'!D3. Thanks in advance - the thoughtful answers on Stack Overflow have gotten me this far!
to counter every possible scenario do it like this:
=ARRAYFORMULA(IFERROR(VLOOKUP(LOWER(REGEXREPLACE(A2:A, "-|\s", )),
{REGEXEXTRACT(LOWER(REGEXREPLACE('Q2 Sales'!A2:A, "-|\s", )),
TEXTJOIN("|", 1, LOWER(REGEXREPLACE(A2:A, "-|\s", )))), 'Q2 Sales'!B2:B}, 2, 0)))
I'm developing a Weka app like Akinator by using the j48 method.
Sample:
http://jbossews-vdoctor.rhcloud.com/doctor
The following is the app's table definition and sample data
qa means question id(Please refer the master which can be set by user) + answer(1:Yes, 2: I don't know, 3: No).
1 line per 1 question & answer.
id,qa,class
A,13,1
A,23,1
B,13,2
B,21,2
The point is to find a way to select the question which can maximize the entropy.
Currently this app is regarding first node id of decision tree as the best question.
And then it narrows down the options by this elimination way.
But the accuracy was too bad to run correctly so I'd like to improve it.
I noticed that the qa column was identified as numeric so it could not build the correct decision tree.
I am confused what I should do for improvement. Dataset? Table definition? Logic?
This is quite a broad question that you are asking, and without code or a clear understanding of the problem it is quite difficult to answer, but I'll give some tips for improvement:
Table Definition
What may have made more sense here is to have an attribute for each question, instead of using a single instance per question. For Example, instead of id, qa and class, you could have A, B, C, D, E, F and Disease. (I believe there were six questions, and naming each attribute would be recommended instead of A-F)
Dataset
You will need at least as many cases as there are diseases, if not more for defining multiple subsets of the problem space for the same disease. There are likely cases where some questions are irrelevant or missing, and the model may need to handle such situations.
Logic
In such a case, you might be able to do the questionnaire by starting with the root node and asking questions until you reach the estimated class. This way, you can ask from node to node until a class is reached.
I hope this helps in improving your existing model.
NOTE: I tried your questionnaire and answered No to all of your questions, and I strangely ended up with Trichomoniasis. Perhaps there could be a 'No Disease' category for your training data also.
My nominal qa data is building such a decision tree by binary split.
actually this structure won't make sense because there is tree at only one side. When qa equal 23 it would be always '3' answer. It's irrational.
http://www.fastpic.jp/viewer.php?file=2693704973.jpg
You should first reformat your features to get all possible questions A,B,C,D... as binary features and your final answer (ie. what to guess) as target class if you want your tree to get a sequence of questions reaching to your answer. Your data will certainly be sparse (many questions without data/answer).
By the way, a binary tree is not the right ML structure and algorithm to build an Akinator like or 20Q/Guess-who. Please look some suggestions here: https://stats.stackexchange.com/questions/6074/akinator-com-and-naive-bayes-classifier
I have a problem. I have an XML tree which looks similar to this:
<wd:meta>
<wd:creation time="[TIMESTAMP]" />
<wd:title><![CDATA[Nice title]]></wd:title>
</wd:meta>
And there are many more siblings with the same Structure.
This tree goes into the XSLTProcessor and gets a nice Stylesheet.
Now i want to take this apart into months (In my Stylesheet). So that there is something like that:
Everything that happed in August
Nice title 1
Nice title 2
Everything that happend in September
Nice title 3
Nice title 4
How can i do something like this? I made a little bit of research but i wasn't very successful.
The only thing i found what would be maybe useful was that: following-sibling
Can anyone help me? I really appreciate your help.
Thanks.

I now used the Muenchian method adopted from http://www.jenitennison.com/xslt/grouping/muenchian.html but i only can order it by month, NOT by year. I tried the Answer of the possible duplicate and tried to understand it, but it's not that easy. Has anyone a easier solution?
In a first step i would iterate your content and generate a monthname for your timestamps. Then you can sort it by the month name. If you have xslt 2.0 you can use group-by to group them by month. If not, you can acturlly iterate your content and check if there is a following-sibling with the current month name. If so, go on with the same month name as the month of the current element. If not, start a new month.
