Suppose you pose a linguistic discrimination task of some sort -- and a supervised learning algorithm, trained on a mass of data, can solve it with 97% accuracy. The algorithm's pattern of errors may indicate to YOU, intuitively, that it doesn't really understand what's going on. But then, it may be that the average person solves the task with only 95% accuracy, though with a different pattern of errors that indicates intuitively they have a different kind of understanding... I like the idea of a language learning challenge, but posing it properly seems tricky. As soon as something becomes a "challenge", one has to worry about protecting against various subterfuges (deception, once again!). Suppose one poses a challenge to learn a language from an un-annotated corpus of texts. OK, but then some nefarious clever person can try to solve this using an algorithm whose parameters were all carefully tuned via analysis of an annotated corpus in that same language. And these parameters may be quite complex structures. The winning approach would then not be able to work on another language for which there was no large annotated corpus (no Penn Treebank analogue, etc.). It seems that challenges are easier to formulate for engineering breakthroughs than science breakthroughs... Here is one idea, off the top of my head.... Perhaps at least it can stimulate thoughts .... This is not about language learning, though, it's about recognizing and generating coherent, meaningful language.. I) Show human subjects some videos of game characters carrying out certain sequences of behaviors in a video-game environment 2) For each behavior-sequence B, ask the human subjects to generate some textual instructions, that would enable the reader to emulate behavior-sequence B (even if the reader had not seen the videos) 3a) Ask the AI to figure out which textual instructions would actually EFTA00846873 work, for each behavior-sequence B 3b) Ask the AI to actually generate textual instructions, based on behavior-sequences (then the judgment is whether people, when following, the Al's instructions, actually carry out the appropriate sort of behavior sequence) Note that 3a and 3b both measure "coherence" in a concrete and obviously meaningful way... I remember seeing some NL generation challenge vaguely like this a few years ago, but don't have the link handy. Ruiting will probably be able to find the reference if it's of interest... For language learning, the only good way I can think of to make a challenge would be to use languages for which there are no annotated corpora. So, the challenge would be to take some unannotated text (or speech) from an arbitrary human language (could be an Australian aboriginal language, or an African language, etc.), and then figure out how to generate grammatical and coherent utterances in that language. This is pretty hard obviously. If someone chose to "cheat" by building annotated corpora or rule-bases for every obscure language in the world, at least they would be doing the world a big service along the way ;-D Interesting thought-direction, anyhow... ! -- Ben On Mon, Sep 7, 2015 at 4:23 AM, Jeffrey E. <jeevacation®gmail.com> wrote: > I dont want statistical modeling you and ben for years have stated you > wanted to put an avatar , and hope it can do things a 2 year old can do. > the challenge is learning a language. different that moving blocks in a > video game. > On Sun, Sep 6, 2015 at 2:38 PM, Joscha Bach <1 > wrote: >> This challenge idea is excellent; I really love it! >> > first draft. of the Chomsky Challenge. .
