"# Causal program-aided language (CPAL) chain\n",
"\n",
"The CPAL chain builds on the recent PAL to stop LLM hallucination. The problem with the PAL approach is that it hallucinates on a math problem with a nested chain of dependence. The innovation here is that this new CPAL approach includes causal structure to fix hallucination.\n",

"\n",
"Like PAL, CPAL intends to reduce large language model (LLM) hallucination.\n",

"The CPAL chain is different from the PAL chain for a couple of reasons.\n",
"\n",
"CPAL adds a causal structure (or DAG) to link entity actions (or math expressions).\n",
"The CPAL math expressions are modeling a chain of cause and effect relations, which can be intervened upon, whereas for the PAL chain math expressions are projected math identities.\n"
