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...

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,...

Ogive Graph01:07

Ogive Graph

5.6K
An ogive graph is sometimes called a cumulative frequency polygon. It is one type of frequency polygon that shows cumulative frequency. In other words, the cumulative percentages are added to the graph from left to right. An ogive graph plots cumulative frequency on the vertical y-axis and class boundaries along the horizontal x-axis. It’s very similar to a histogram; only instead of rectangles, an ogive displays a single point where the top right of the rectangle would be. Creating this...

The Representativeness Heuristic02:13

The Representativeness Heuristic

15.8K
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

    Area of Science:

    • Artificial Intelligence
    • Data Science
    • Machine Learning

    Background:

    • Temporal knowledge graph (TKG) reasoning is crucial for inferring future events from historical data.
    • Current state-of-the-art (SOTA) subgraph-based methods excel at local information but struggle with complex topological patterns.

    • To improve the accuracy and efficiency of future event prediction.

    Main Methods:

    • Constructs candidate-oriented relational graphs to represent local TKG structures.
    • Employs a variant graph neural network with a recursive propagation architecture and self-attention mechanism.
    • Utilizes a prior directed temporal edge sampling method and a scoring function for prediction.

    Main Results:

    • The proposed approach achieves stronger inference capabilities compared to SOTA methods on benchmark datasets (ICEWS14, ICEWS18, ICEWS0515, YAGO).
    • Demonstrates faster convergence rates in experimental evaluations.
    • Provides interpretable relational graphs for each query-candidate pair, enhancing result transparency.

    Conclusions:

    • The novel subgraph-based method effectively captures complex relational patterns in TKGs.
    • The approach offers significant improvements in inference accuracy and convergence speed.
    • The interpretability of the generated relational graphs aids in understanding TKG prediction outcomes.
