For neuralnetworks mathematica likes 2 ways to structure trainingsets:



listFormatData = "Input" -> input2, "OutputKey1" -> OutputKey1Input2Output, ...


and 



assocFormatData = <|
"Input" -> input1, input2, ..., 
"OutputKey1" -> OutputKey1Input1Output, OutputKey1Input2Output, ...
, ...
|>


Is the a stock way to convert these 2 formats properly?



concrete examples:



listData = 
<


and 



assocData = <|
"Input" -> 1, 2, 3, 
"double" -> 2, 4, 6, 
"squared" -> 1, 4, 9

    A function that is of great use here, is AssociationTranspose in the GeneralUtilities package. It does the same thing as regular transpose, but works with List and Associations alike (and mixtures of the two):



    listData = >,
     <;
    assocData = <|"Input" -> 1, 2, 3, "double" -> 2, 4, 6, "squared" -> 1, 4, 9|>;
    GeneralUtilities`AssociationTranspose[listData] === assocData
    GeneralUtilities`AssociationTranspose[assocData] === listData




    Out[11]= True

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
