# How Samsung Uses Two AI Models to Improve Sentence Generation > A method for training an AI to write better sentences by using a second model that reads or generates text in a different order to grade the first model's work. - **Patent:** US 11727263 - **Original title:** Method of updating sentence generation model and sentence generating apparatus - **Owner:** Samsung Electronics Co Ltd - **Granted:** 2023 - **Status:** Active - **Times cited:** 1 - **Field:** ai_ml, consumer_electronics, software, telecommunications ## What it does This patent describes a way to train a machine learning model to generate text more accurately. It uses two 'decoding models'—essentially the parts of an AI that pick the next word in a sentence. The first model generates a target sentence, while the second model acts as a critic by generating words in a different order (such as backward) to calculate 'reward information.' This reward information acts like a score, telling the first model how good its sentence was, which is then used to update the first model's internal weights to improve future performance. ## What it does NOT cover - Does not cover simple text generation that lacks a secondary, order-reversed validation model. - Does not cover training methods that rely solely on human-provided labels or static datasets. - Does not cover architectures that do not use neural network weight resetting as the primary training mechanism. ## The clever bit By forcing the second model to process or generate words in a different order (like backward), the system gains a structural check on the first model's output, helping to catch errors that a forward-only model might consistently repeat. ## Real-world examples 1. Samsung Bixby voice assistant responses 2. Automated machine translation software 3. Predictive text and smart reply features in mobile operating systems ## Why it matters As AI-driven text generation becomes standard in consumer electronics, improving the quality of machine-generated language without massive amounts of human-labeled data is a major technical hurdle. This approach helps Samsung refine its virtual assistants and automated translation tools by creating a self-improving loop between two different AI perspectives. ## Frequently asked questions ### What does How Samsung Uses Two AI Models to Improve Sentence Generation cover?
