为了让大模型的可解释性走的更深,我们构造了一些含有深层逻辑的语法树(context-free grammar, or CFG),并且逆向研究了GPT是如何学会这些CFG语法的。结果表明,GPT竟然悄咪咪的学会了做动态规划! 论文地址:https://arxiv.org/abs/2305.13673 物理学 人工智能 ChatGPT 深度学习 大模型 逆向工程 解释性 语言模型 ...

free languages. So there must exist some languages that are not context-free. Example: {a n b n c n } Showing that a Language is Context-Free Techniques for showing that a language L is context- free: 1.Exhibit a context-free grammar for L. 2.Exhibit a PDA for L. 3.Use the ...
A production example : S->aS;S->abc; Maybe you know another grammar called context sensitive grammar. Then, what’s the differences between context free grammar and context sensitive grammar ? The most important difference is production rules : the left hand side of a context free grammar prod...

CFG CFG Example • Language of palindromes – We can easily show using the pumping lemma that the language L = { w | w = w R } is not regular. – However, we can describe this language by the following context-free grammar over the alphabet {0,1}: P P 0 P 1 P 0P0 P 1P1...
I am attempting to write a context-free grammar for L = the set of strings in which the number of 1’s is one more than the number of 0’s. Thus, 1011010, 0001111 etc. are in L, but strings like 001101, 000011 etc. are not in L. So far, I have a cont...
