Transposing a matrix by similarity operations

Synthetic Similarity Matrix Generation

On the Similarity of Process Change Operations

Process flexibility is a vital part for almost any business area. Change logs are a central asset for documenting adaptations in processes, since they capture key information about associated change operations. Comparing multiple change operations offers interesting data for many analysis questions, e.g., for analyzing previously applied change operations and for supporting users in future adap...

Computational Improvements to Matrix Operations

An alternative to the matrix inverse procedure is presented. Given a bit register which is arbitrarily large, the matrix inverse to an arbitrarily large matrix can be peformed in O(N 2) operations, and to matrix multiplication on a vector in O(N).

Efficient similarity-based operations for data integration

Dealing with discrepancies in data is still a big challenge in data integration systems. The problem occurs both during eliminating duplicates from semantic overlapping sources as well as during combining complementary data from different sources. Though using SQL operations like grouping and join seems to be a viable way, they fail if the attribute values of the potential duplicates or related...

Transposing Chroma Representations to a Common Key

Chroma representations of musical excerpts are nowadays very popular and used for a wide variety of applications. Within these, transposition to a common key or tonality can represent an important aspect, usually having a dramatic impact to final system’s accuracy. We present and evaluate a new and straightforward way for transposing two chroma representations to a common key that outperforms p...
