The Attentional Blink08:52

The Attentional Blink

17.0K
Source: Laboratory of Jonathan Flombaum—Johns Hopkins University
In order for recognition of a certain stimulus to take place, visual attention needs to be directed towards said stimulus. To the earliest parts of the visual system, objects are not objects, they are collections of visual features-lines, corners, changes in texture, color, and light. Attention is the resource that is necessary for later processing in order to recognize what a given bundle of features adds up to. This makes...

Artificial Intelligence-Based System for Detecting Attention Levels in Students

5.3K
This paper proposes an artificial intelligence-based system to automatically detect whether students are paying attention to the class or are distracted. This system is designed to help teachers maintain students' attention, optimize their lessons, and dynamically introduce modifications in order for them to be more...

Self Within Cultural Contexts

218
Cultural frameworks for understanding the self are often categorized into two broad orientations: individualism and collectivism. These paradigms influence how people define themselves, relate to others, and interpret their social worlds. Each orientation offers distinct perspectives on autonomy, responsibility, and the role of the individual within a community.Individualistic CulturesIn individualistic cultures like North America and Western Europe, identity is understood as autonomous and...

Measurement of Neurophysiological Signals of Ignoring and Attending Processes in Attention Control

9.5K
Attention control comprises enhancement of target signals and attenuation of distractor signals. We describe an approach to measure separately but concurrently, the neurophysiology of attending and ignoring in sustained intermodal attention, utilizing a passive control condition during which neither process is continuously engaged.

The human visual system is incredibly sophisticated and capable of processing large amounts of information very quickly. However, the brain's capacity to process information is not an unlimited resource. Attention, the ability to selectively process information that is relevant to current goals and to ignore information that is not, is therefore an essential part of visual perception. Some...

Protein Networks02:26

Protein Networks

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Area of Science:

  • Computer Science
  • Artificial Intelligence
  • Data Science

Background:

  • Network embedding (NE) methods like DeepWalk, Node2vec, and LINE excel at homogeneous networks but struggle with real-world heterogeneous networks containing diverse node information.
  • Existing methods face challenges in jointly embedding topological structure and heterogeneous node features (e.g., text, properties) into a unified low-dimensional space.
  • Quantifying edge strength in unweighted networks and preserving node context relations remain difficulties for current NE techniques.

Purpose of the Study:

  • To propose a novel network embedding method, Context Attention Heterogeneous Network Embedding (CAHNE), designed to address the limitations of existing approaches in handling heterogeneous networks.
  • To accurately capture both the topological structure and rich heterogeneous information of nodes within a unified embedding space.
  • To improve the performance of network embedding tasks by effectively quantifying edge importance and leveraging contextual information.

Main Methods:

  • CAHNE introduces the concept of 'node importance' to dynamically measure edge strength, enhancing context preservation in unweighted networks.
  • The method integrates text information by learning context embeddings through a 'context node sequence'.
  • An attention mechanism is incorporated to weigh the influence of context nodes on the current node's embedding, refining feature representation.

Main Results:

  • Experimental results on real-world datasets demonstrate CAHNE's superior performance compared to state-of-the-art baseline methods.
  • CAHNE achieved higher quality in network reconstruction, link prediction, and node classification tasks.
  • The method also showed effectiveness in network visualization, providing clearer representations of complex network structures.

Conclusions:

  • CAHNE effectively bridges the gap in network embedding for heterogeneous networks by jointly considering topology and diverse node features.
  • The proposed 'node importance' and context attention mechanisms significantly enhance the representation of network structure and node relationships.
  • CAHNE offers a robust and high-quality solution for various network analysis tasks, outperforming existing state-of-the-art methods.
