    I'm getting myself really confused. Should there be the ' in "examples" in this sentence?

    The loss of information of the forward transformation is defined to be the sum of the squared reconstruction errors for each of the training example’s input vectors.

    My head hurts just trying to read the sentence, let alone work out if the grammar is correct :o

    I think the answer is no and that its correct as it is but don't take my word - lets wait for one of the brainy people to post :o

    Now this type of example always confuses me but I think so yes, as the input vectors belong to the training example, so it is possessive.

    eg. Andy's parents were unhappy v Andys parents were unhappy.

    Feel free to tell me I'm wrong grammar nazi's, I probably am :D

    When I was at school, I was always taught that if you read a sentence out loud and needed to pause for a breath before you got to the end, then it needed a comma - going by that rule you need a comma at least...I just have no idea where it would go :o

    If training examples is plural then the apostrophe should be at the end, ie. examples'

    I'm a card-carrying member of the Grammar Nazi party...and you're absolutely right. It's a horrible sentence though. :(

    There should be no apostrophe in "Nazis" either. :p

    Reword it. It's technically right now but it doesn't read well at all. Just taking out the "of the" makes it much better IMO:

    The loss of information of the forward transformation is defined to be the sum of the squared reconstruction errors for each training example’s input vectors.

    To the OP, the answer is YES there should be. But the sentence is horrible to read :p

    Edit: Oops, what Robmiller just said :o

    Apostrophes are used to show omission or possession. In this case it is possession.

    If there's one "owner" add an apostrophe and then s *
    If there's more than one "owner" - add s then an apostrophe

    *There are exceptions of course :)

    Kitten was, no? There must be an apostrophe there surely.

    I don't want to have to re-enact the Night of the Long Knives on you! :mad:

    The way Lagz has worded the sentence means that examples is a plural. That might not have been his intention, but as it is worded, it should be examples' not example's ;) I'm disappointed in you :p

    How do you know that examples is plural? There are multiple vectors, but there may just be a single training example.

    The Grammar Nazi party is tearing itself apart from within already; we must instead unite against the common enemy. ;)

    'each' implies plural does it not? :p

    Each of the vectors (multiple) of the training example (single) was how I read it.

    It was hard enough to read and understand that there may be several possible interpretations though. :)

    Edit: VIRII seems to be agreeing with me. :confused: I hope this sets a new precedent for future arguments. :p
