Deductive Reasoning01:16

Deductive Reasoning

55.2K
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...

Reason and Intuition01:37

Reason and Intuition

6.4K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Time-Series Graph00:54

Time-Series Graph

4.3K
A time-series graph is a line graph with repeated measurements taken at successive intervals of time. It is also called a time series chart. To construct a time-series graph, one must look at both pieces of a paired data set. The horizontal axis is used to plot the time increments, and the vertical axis is used to plot the values of the variable that one is measuring. By using the axes in this way, each point on the graph will correspond to time and a measured quantity. The points on the graph...

Inductive Reasoning00:59

Inductive Reasoning

60.4K
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...

Reasoning01:30

Reasoning

73
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,...

Storage01:23

Storage

83
A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

Area of Science:

  • Artificial Intelligence
  • Data Science
  • Knowledge Representation

Background:

  • Temporal Knowledge Graphs (TKGs) model evolving information and events.
  • TKG extrapolation is crucial for predicting future events based on historical data.
  • Existing methods struggle with long-term history and concurrent event interactions.

Purpose of the Study:

  • To propose a novel method, PLEASING, for enhanced TKG extrapolation.
  • To address limitations in modeling long-distance history and concurrent event interactions.
  • To improve the accuracy and comprehensiveness of TKG reasoning.

Main Methods:

  • Introduced a two-step reasoning framework: PotentiaL concurrEnt Aggregation and contraStive learnING (PLEASING).
  • Employed two encoders (historical and global events) with an adaptive gated mechanism.
  • Constructed auxiliary graphs for temporal interactions and potential concurrent event correlations.
  • Integrated contrastive learning to enhance historical query identification.

Main Results:

  • PLEASING demonstrated state-of-the-art performance across seven benchmark datasets.
  • The method effectively captures historical correlations and predicts future events.
  • Achieved comprehensive modeling of TKG semantics, including temporal characteristics and future possibilities.

Conclusions:

  • PLEASING significantly advances TKG extrapolation capabilities.
  • The framework offers a holistic approach to investigating temporal dynamics and future potential.
  • The method provides a robust solution for complex TKG reasoning tasks.
