DeepLogic: Joint Learning of Neural Perception and Logical Reasoning
Summary
DeepLogic jointly learns neural perception and symbolic logic, outperforming existing methods. This novel framework enhances both components through mutual supervision for superior AI reasoning capabilities.
Area of Science:
- Artificial Intelligence
- Machine Learning
- Cognitive Science
Background:
- Neural-symbolic learning integrates neural perception and symbolic reasoning.
- Current methods often cascade components, leading to isolated optimization and missed synergistic benefits.
Purpose of the Study:
- To introduce DeepLogic, a framework for joint learning of neural perception and logical reasoning.
- To enable mutual supervision and joint optimization of neural and symbolic components.
Main Methods:
- Developed a deep-logic module for representing first-order logic formulas.
- Proposed a deep&logic optimization algorithm for joint learning.
- Theoretically quantified mutual supervision signals and proved convergence.
Main Results:
- DeepLogic significantly outperforms deep neural network (DNN) and other strong baselines.
- Demonstrated superior model performance, convergence, and generalization capabilities.
- Showcased effective extension to continuous domains.
Conclusions:
- Jointly learning perception and logic in a weakly supervised manner yields significant performance gains.
- DeepLogic offers a powerful new approach for advancing neural-symbolic AI.
- The framework effectively leverages mutual enhancement between neural and symbolic learning.

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

Reasoning is the action of thinking about something in a logical, sensible way. It is integral to problem-solving, decision-making, and critical thinking. Reasoning can be inductive or deductive. Reasoning involves transforming information into conclusions, which is essential for problem-solving, decision-making, and critical thinking.
Inductive reasoning involves deriving generalizations from specific observations. This type of reasoning helps form beliefs about the world. For example,...

Deductive reasoning, or deduction, is the type of logic used in hypothesis-based science. In deductive reasoning, the pattern of thinking moves in the opposite direction as compared to inductive reasoning, which means that it uses a general principle or law to predict specific results. From those general principles, a scientist can deduce and predict the specific results that would be valid as long as the general principles are valid.
For example, a researcher can deduce specific predictions...

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

Inductive reasoning is a form of logical thinking that uses related observations to arrive at a general conclusion. It is uncertain and operates in degrees to which the conclusions are credible. As such, inductive arguments can be weak or strong, rather than valid or invalid, and conclusions can be used to formulate testable, falsifiable hypotheses.
Inductive reasoning is common in descriptive science. A life scientist makes observations and records them. This data can be qualitative or...
