Reply to comment by master3243 in [R] Nonparametric Masked Language Modeling - MetaAi 2022 - NPM - 500x fewer parameters than GPT-3 while outperforming it on zero-shot tasks by Singularian2501

But what I'm asking is, how do the benchmarks match real world performance? Because I've seen claims that other language models were supposedly close to or equal to GPT-3 in this or that benchmark, but try interacting with them and the difference is striking. It's like the difference between talking to a college grad student and talking to the meth addled homeless guy who shouts at lampposts.

From the paper:

>Extension for generation. It is currently non-trivial to use NPM for generation, since it is the encoder-only model. Future work can explore autoregressive generation as done in Patel et al. (2022) or use NPM for editing (Schick et al., 2022; Gaoet al., 2022).

So, don't expect to talk to it just yet.

There was a thread awhile back about one benchmark being filled with spelling errors, grammar errors, and wrong answers. In many cases there were multiple correct answers but one was picked as the correct answer for no particular reason. Creating a benchmark for the subjective task of "is this text good?" seems to be pretty hard. It's even harder when the people creating the benchmark have a poor grasp of language.

If I were to ask a language model "Describe an apple." There are many correct answers, none more correct than the others. Multiple independent humans would have to go over the answers and make subjective decisions on if the LLM answerded well. This becomes much more difficult with better LLMs because the prompts and answers have to become more complex, which makes reviewing the answers harder and more time consuming.
