Submission GuidelinesHello,
After used the new "Image Recognition Tool" a few days, I think you could improve it :
> by adding the dimensional constraints in front of each of the pre-trained models,
> by adding a true tool to divide the training data correctly (in order to have an equivalent number of images for each of the labels)
> at least, allow the tool to use black & white images (I wanted to test it on the MNIST, but the tool tells me that it necessarily needs RGB images) ?
Question : do you in the future allow the user to choose between CPU or GPU usage ?
In any case, thank you again for this new tool, it is certainly perfectible, but very simple to use, and I sincerely think that it will allow a greater number of people to understand the many use cases made possible thanks to image recognition.
Thank you again

Thank you again.

Currently there is a function in Alteryx called FindString() that finds the first occurrence of your target in a string. However, sometimes we want to find the nth occurrence of our target in a string.
FindString("Hello World", "o") returns 4 as the 0-indexed count of characters until the first "o" in the string. But what if we want to find the location of the second "o" in the text? This gets messy with nested find statements and unworkable beyond looking for the second or third instance of something.
I would like a function added such that
FindNth("Hello World", "o", 2) Would return 7 as the 0-indexed count of characters until the second instance of "o" in my string.
The Formula Tool does a good job of autocompleting expressions (for example an open square bracket will show you variables in your dataset), as well as syntax highlighting (coloring variables, keywords, strings, etc).
I propose having this feature available in all tools that use the expression editor, particularly common ones such as the Multi-Row Formula Tool and the Multi-Field Formula Tool.
This parity across tools would provide a more consistent experience for the user and increase one's productivity using these tools. It's incredibly helpful for beginners and seasoned Alteryx users alike and should be available wherever possible.
When configuring a FILTER tool, the results of your formula are uncertain until you RUN/PLAY the workflow. Compare that experience with the configuration of a FORMULA tool where you see a "Data Preview" of the first record results.
TRUE or FALSE could readily be added to the Filter Tool and save the execution time for the workflow.
When you get to HTML tool versions, you could check many rows of data and potentially give back counts of TRUE and FALSE results as well.
I'll put this on my x-mas list and see if Santa has me on the naughty or nice list.
Cheers,
Mark
When using the formula tool -- one of the nice features is that when you start typing in a function or variable -- the tool will show formulas/variables that begin with that letter and keep changing as you type in more letters. I believe this is called predictive typing.
However, this does not happen in tools like multi-row or multi-field where a user would have to search for functions and variables if they weren't sure what they are.
Can predictive typing be added to the multi-row and multi-field tools? If I want to take it further, any tool that allows a user to use the formula functionality should be able to see predictive typing.
Thanks,

Ok the time has come to expand functionality in the record ID tool. I would like the ability to restart the counter based on a field (e.g zip code). You can do it quickly in Tableau (see image) so why not have this functionality readily available in Alteryx? Sure, you can already do it in Alteryx - the long way - with the generate rows tool, look at previous/active row with certain condition and do +1 or something like that.
Having a simple restart counter in Record ID tool just makes sense. It's intuitve to have it there, and it's easier to use than generate rows tool. IMHO also easy to develop by Alteryx and +1 for Alteryx in gartner magic quadrant!
The v10 formula configuration window had two very small advantages. First, it always had an extra 'line' for another output field (no pressing '+' required). Second, it defaulted to letting you immediately begin typing the name of the next column (no need to press 'Select Column' then 'Add New Column'). I know these are minor, but every little thing counts when you're doing heavy development.
It has been brought up that the following comments were given during the beta. While I appreciate the reasoning of requiring 'obvious intention,' my personal opinion is that it is overkill in this scenario. Even for new users, the old design was quite intuitive.
"Thanks for taking the time to provide feedback! This touches a conversation topic that has been ongoing here at Alteryx. While we want workflow development to be as fast as possible, we also are trying to address the overall usability of the tool and make sure it is very clear what we intend the user to do. We decided to have the UI ask for an explicit action (pick an existing field to edit or click to add a new field) to help make those options clear, as we have found that users don't always understand from the existing tool that this is the first decision they should make when using the tool. That being said, your feedback is definitely valuable. I will be sure to bring this up as we are making improvements to the new tool and see if there's a compromise that we can make on speed vs. obvious intention. Thanks for taking the time!"
I have need to Unique my data on all fields. However, I do not know all the fields that will be in my data because of a Dynamic Select tool (or in some cases a Cross Tab tool). The Unique tool defaults to having any new fields be unchecked in its configuration. Without finding some work around, I will be unable to schedule this workflow or turn it into an app for use on the Gallery without risking duplication caused by the Unique tool that fails to capture new/different fields that may come through the data.
To solve this problem and be consistent with other tools in Alteryx, the following features need to be added to the Unique tool:
In Alteryx 11 the formula tool got redesigned but multi-field and multi-row tools have been left as it. It would be nice to have formula autocomplete and other new features in these tools as well.
It would be really usefull when we can filter fields by name and make selection. At times I have work with 300+ fields and it's really hard to scroll down to select few fields. Tableau has this feature. Wer can have this feature in select and all embedded select tools (join, append etc)
When creating a formula with the formula tool, it would be useful to be able to quickly tab into the data type column, then press D for Double and select this quickly.
Right now, you cannot use the keyboard to quickly type-ahead in this field, so every double field requires you to select, drop down, move the mouse to the bottom of the scroll window, click scroll down, then mouse back up to D for double.
(or "S" for Spatial etc - this is standard for most drop-down boxes)
Sometime I confused DateTimeParse(dt,f) and DateTimeFormat(dt,f).
My idea is changing "DateTimeParse(dt,f)" to "DateTimeParse(string,f)" when we select DateTimeParse from function list.
Because DateTimeParse uses string type data as a first variables, not datetime type data.
No need to change DateTimeParse function itself.
