Natlog: Embedding Logic Programming into the Python Deep-Learning Ecosystem

Abstract

Driven by expressiveness commonalities of Python and our Python-based embedded logic-based language Natlog, we design high-level interaction patterns between equivalent language constructs and data types on the two sides.By directly connecting generators and backtracking, nested tuples and terms, coroutines and firstclass logic engines, reflection and meta-interpretation, we enable logic-based language constructs to access the full power of the Python ecosystem.We show the effectiveness of our design via Natlog apps working as orchestrators for JAX and Pytorch pipelines and as DCG-driven GPT3 and DALL.E prompt generators.Keyphrases: embedding of logic programming in the Python ecosystem, high-level inter-paradigm data exchanges, coroutining with logic engines, logic-based neuro-symbolic computing, logic grammars as prompt-generators for Large Language Models, logic-based neural network configuration and training.
