DECIDER: A Rule-Controllable Decoding Strategy for Language Generation by Imitating Dual-System Cognitive Theory


핵심 개념
DECIDER is a rule-controllable decoding strategy inspired by dual-system cognitive theory, enabling more human-like language generation.
초록
DECIDER introduces a rule-controllable decoding strategy for language generation inspired by dual-system cognitive theory. It focuses on high-level reasoning and follows certain rules to guide text generation towards specific targets in a more human-like manner. The method incorporates a logical reasoner that takes high-level rules as input and allows rule signals to flow into the pre-trained language model at each decoding step. By balancing text quality and target satisfaction, DECIDER demonstrates effectiveness in generating higher-quality and target-meeting text.
통계
Lexicon-based constrained decoding approaches aim to control the meaning or style of generated text through certain target concepts. Existing approaches over-focus on the targets themselves, leading to a lack of high-level reasoning about how to achieve them. DECIDER can effectively follow given rules to guide generation direction toward the targets in a more human-like manner.

"Extensive experimental results demonstrate that DECIDER can effectively follow given rules to guide generation direction toward the targets in a more human-like manner."

How does DECIDER's approach differ from traditional unconstrained decoding methods

DECIDER's approach differs from traditional unconstrained decoding methods in several key ways. Firstly, DECIDER introduces a rule-controllable decoding strategy that focuses on following high-level rules rather than just targeting specific keywords or concepts. This allows the model to generate text in a more human-like manner by considering not only the targets but also semantically relevant concepts that contribute to achieving the targets. Secondly, DECIDER incorporates a logical reasoner and decision function into the decoding process. The logical reasoner evaluates high-level rules expressed in First-Order Logic (FOL) to determine which words meet the rule criteria. The decision function then combines decisions from both neural and logic systems to guide generation towards words that satisfy the rules. Overall, DECIDER's approach shifts away from simply optimizing for target satisfaction towards incorporating higher-level reasoning and controllability into language generation tasks.

What are the implications of incorporating dual-system cognitive theory into natural language processing tasks

Incorporating dual-system cognitive theory into natural language processing tasks has significant implications for how models approach language generation. By imitating dual-system cognitive theory, as seen in DECIDER, models can mimic human decision-making processes through an interplay between intuitive System 1 (S1) and logical System 2 (S2). This allows models to make decisions based on both intuition and conscious reasoning, leading to more nuanced and contextually appropriate responses. Dual-system cognitive theory helps models consider not only immediate goals or targets but also broader strategies or plans for achieving those goals. This can result in more coherent and realistic text generation by guiding models to focus on relevant information beyond just surface-level keywords. Additionally, incorporating dual-system cognitive theory can enhance model interpretability by providing insights into how decisions are made during language generation tasks. By understanding how S1 and S2 interact within the model, researchers can gain deeper insights into its behavior and potentially improve performance further.

How might DECIDER's rule-controllable decoding strategy impact future developments in language generation technology

DECIDER's rule-controllable decoding strategy could have several impacts on future developments in language generation technology: Improved Controllability: Future language generation models may adopt similar rule-based approaches like DECIDER to allow for better control over generated text output. This could lead to more tailored responses based on specific requirements or constraints provided by users. Enhanced Human-likeness: By focusing on mimicking human decision-making processes inspired by dual-system cognitive theory, future models may be able to generate text that is more aligned with human thinking patterns and behaviors. Advanced Customization: The ability of DECIDER to follow user-defined rules opens up possibilities for highly customizable language generation systems tailored for specific use cases or domains. Interpretability: Models built using a framework similar to DECIDER may offer greater interpretability due to their explicit modeling of high-level reasoning processes alongside neural network-based predictions. Task-specific Generation: Rule-controllable decoding strategies could enable fine-tuning of generated text according to specific task requirements such as sentiment analysis, topic control, or keyword constraints with improved accuracy and flexibility. Overall, integrating rule-controllable decoding strategies like DECIDER could pave the way for more sophisticated and adaptable language generation technologies in various applications ranging from chatbots to content creation tools."
