  In this paper, we present an approach to building neural representations of the Wikipedia category graph. We test four different methods and examine the neural embeddings in terms of preservation of graphs edges, neighborhood coverage in representation space, and their influence on the results of a task predicting parent of two categories. The main contribution of this paper is application of neural representations for improving the...

• Coupling coefficients for the space group of the hexagonal close-packed structure

  Publikacja

  • L. Ziemczonek

  - Rok 1984

  We have computed the Clebsch-Gordan coefficients of the representations for the space group of the hexagonal close-packed structure for the points:V, A, H, K, L, M. We enumerate all arms of the wave vector stars and all wave vector selection rules.

• A comparison of geometric analogues of holographic reduced representations, original holographic reduced representations and binary spatter codes

  Publikacja

  • -. Ł. A. Patyk
  • M. Czachor
  • D. Aerts

  - Rok 2011

  Geometric Analogues of Holographic Reduced Representations (GA HRR) employ role-filler binding based on geometric products. Atomic objects are real-valued vectors in n-dimensional Euclidean space and complex statements belong to a hierarchy of multivectors. The paper reports a battery of tests aimed at comparison of GA HRR with Holographic Reduced Representation (HRR) and Binary Spatter Codes (BSC). Firstly, we perform a test of...

• Experiments on Preserving Pieces of Information in a Given Order in Holographic Reduced Representations and the Continuous Geometric Algebra Model

  Publikacja

  • A. Patyk-Łońska

  - Informatica - Rok 2011

  Geometric Analogues of Holographic Reduced Representations (GAc, which is the continuous version of the previously developed discrete GA model) employ role-filler binding based on geometric products.Atomic objects are real-valued vectors in n-dimensional Euclidean space and complex statements belong to a hierarchy of multivectors. The property of GAc and HRR studied here is the ability to store pieces of information in a given...

• ELECTIVE PROJECT II _sem 5_Green Story - Free Time Space

  Kursy Online

  • K. Życzkowska

  The topic of the course - Green Story - Free Time Space, joins green architecture and a place to spend free time - inside and outside – to read, to eat, to relax. The idea is to design green – to give back the greenery to the public square – to make a city space more friendly for users and more friendly to the environment.  You can design a story, to make a space more attractive. You can design a Green Story, to make people more...

• Automatic Regularization by Quantization in Reducible Representations of CCR: Point-Form Quantum Optics with Classical Sources

  Publikacja

  • M. Czachor
  • K. Wrzask

  - INTERNATIONAL JOURNAL OF THEORETICAL PHYSICS - Rok 2009

  Electromagnetic fields are quantized in a manifestly covariant way by means ofa class of reducible "center-of-mass N-representations" of the algebra of canonical commutationrelations (CCR). The four-potential Aa(x) transforms in these representations as aHermitian four-vector field in Minkowski four-position space (without change of gauge), butin momentum space it splits into spin-1 massless photons and two massless scalars. Whatwe...
