Originality, a key aspect of creativity, is difficult to measure. We tested the relationship between originality and similarity in two semantic spaces: latent semantic analysis (LSA) and pointwise mutual information (PMI). Similarity in both spaces was negatively correlated with human judgments of originality of responses on a test of divergent thinking. PMI was correlated more strongly both wi...

Through the analysis of collaborations in an online virtual community, the impact of originality on popularity and practicality is tested. These tests in turn are based on a method for measuring the distance between 3D shapes. In sum, this paper presents a new method for gauging innovation, and suggests ways of further understanding the role technology plays in encouraging creativity. From an o...

Often, the information is sensitive or private in nature and these sensitive data when mined violates the privacy of the individuals. Privacy preserving data mining (PPDM) mines the data but intends to preserve the privacy of susceptible data without ever actually seeing it. This paper recaps the important techniques in PPDM like anonymization, perturbation and cryptography. Nowadays, data mini...

Quantum query complexity is known to be characterized by the so-called quantum adversary bound. While this result has been proved in the standard discretetime model of quantum computation, it also holds for continuous-time (or Hamiltonianbased) quantum computation, due to a known equivalence between these two query complexity models. In this work, we revisit this result by providing a direct pr...
