• The results showed that marginally well-fed spiders build cobwebs with significantly longer length of anchor silk, lower retreat to the ground, more number and longer gumfooted lines, and larger capture area, while extremely well-fed spiders build cobwebs with significantly bigger retreat volume and higher height of retreat to the ground. (bvsalud.org)

  • COBWEB is an incremental system for hierarchical conceptual clustering. (wikipedia.org)
  • Here's a quick recap based on [2]: In concept formation, we observe unlabeled examples one after another and try to find a clustering of these examples into categories, which are then organized in a conceptual hierarchy. (lucas-bechberger.de)
  • Concept formation algorithms typically follow an incremental hill-climbing process, where the conceptual hierarchy is updated after each observation. (lucas-bechberger.de)
  • How are concepts and the conceptual hierarchy defined in COBWEB? (lucas-bechberger.de)
  • The overall conceptual hierarchy is represented as a tree and each inner node corresponds to one concept. (lucas-bechberger.de)
  • Okay, so how does COBWEB construct its conceptual hierarchy? (lucas-bechberger.de)
  • Take the two most appropriate child concepts and merge them - the original child concepts then become "grandchild" concepts under the newly created merged concept. (lucas-bechberger.de)
  • Passing an object down the hierarchy Effectively calling the COBWEB algorithm on the object and the subtree rooted in the node. (wikipedia.org)
  • parent) tells us how frequent this concept is in comparison to its "siblings" in the hierarchy: Given that the observation x belongs to the parent concept P , how likely is it that x also belongs to C ? (lucas-bechberger.de)
  • In Figure 1, this results in a modification of the concept hierarchy from (b) to (a). (lucas-bechberger.de)
  • In Figure 1, we can transition from the concept hierarchy in (c) to the one in (b) by merging C 3 and C 4 . (lucas-bechberger.de)
  • Remove a child concept from the concept hierarchy altogether and promote its children to the next-higher level. (lucas-bechberger.de)
  • Each node in a classification tree represents a class (concept) and is labeled by a probabilistic concept that summarizes the attribute-value distributions of objects classified under the node. (wikipedia.org)
  • concept) represents the distribution of possible feature values for members of the concept: If you know that the observation x belongs to the concept C , which kind of feature values v do you expect it to have? (lucas-bechberger.de)
  • Today, I want to share the basic idea behind COBWEB and its variants. (lucas-bechberger.de)
  • Category utility is inspired by the basic level of categorization in human classification hierarchies, where one in general has a good balance between intra-class similarity (i.e., examples of the same concept are similar) and inter-class dissimilarity (i.e., examples from different concepts are different). (lucas-bechberger.de)
  • Updating a concept description thus simply corresponds to updating those counts, which then directly influences the probability distributions. (lucas-bechberger.de)
  • Mind-Mapping or map of the mind is an advanced technique of free interplay of ideas that stimulates connections, in the form of Cobweb, which constitutes the way in our brain, that works to increase the capacity of intuition, imagination, understanding and memory, take advantage of the creative thinking and raise productivity, quality and enjoyment of the work, using the brain as a whole under the concept of the whole brain.

  • COBWEB(root, record): Input: A COBWEB node root, an instance to insert record if root has no children then children := {copy(root)} newcategory(record) \\ adds child with record's feature values. (wikipedia.org)
  • Yuri Grigorovich's latest version of The Sleeping Beauty (his fifth) follows the Soviet traditions that discreetly downgraded monarchical and religious nuances in the dance formations in order to raise up the sheer prettiness and femininity of classical dancing, and is kind to the audience by being sliced into two long acts, which makes it feel shorter and tauter than the usual three-act deployment.

  • To address this, I drew inspiration from incremental concept formation systems like COBWEB, which construct probabilistic concept hierarchies through online learning from observed examples. (parallaxresearch.org)
  • He classified the patterns into four distinct types that he dubbed "form constants": lattices (including checkerboards, honeycombs and triangles), tunnels, spirals and cobwebs. (getpocket.com)
