Abbreviation hallucinations

Hope I’m not clogging up the feed by posting so much! But I just finished uploading a large batch of documents written by a scribe who puts periods between every words, and Leo had some serious trouble with it. In around half of the transcriptions, it interpreted the periods as abbreviations, which it then filled in with a repeating word across the document. The most common abbreviations were [septiembre] and other months, [mercur], and [Christ]. Perhaps Leo is trying to convert me, haha. When this happened, it would often just start repeating that bracketed abbreviation.



Attaching up some images so you can see!

You are not clogging up the feed at all. Thank you for posting!

This is a very weird kind of hallucination which I haven’t seen before. Hard to say what caused it exactly but the best response for us is probably just to ensure that Leo has seen more examples of this kind of thing. Could you describe the features of this (and any other) hands which don’t seem to work very well?

This is by far the weirdest issue I’ve seen, and the issue seems to be much more with the periods than with the hand itself. By far the biggest issue I’ve had with handwriting is when its slanted, even if it is relatively neat handwriting. I’m attaching a couple examples of hands where I just stopped used Leo, because I wasn’t getting anything useful.

Thanks Josh. It might be because the lines run into each other and/or because of the blotching on the paper. Let us know if you notice anything else about the kinds of images that it tends to struggle with.

I have also encountered an abbreviation hallucination of a different nature, so I thought I would drop it in this thread.

I have noticed that the model has struggled with transcribing this particular signature ‘C Grey’ but this is the first case of where it transcribed it as a hallucinated abbreviation of ‘Earl Culpeper’

Posting here as this appears to be an abbreviation hallucination of a similar kind, if not quite the same. Leo consistently turns the abbreviation for sicca rupees (Sa. Rs.) into the £ sign. Perhaps related to the currency signs most frequently found in the AI training data.
