Subspace Labs Inc., a scalable infrastructure layer solution for Web3 blockchain ecosystems, today announced it raised $32.9 million in a funding round to expand its integrations and start more ...

Subspace codes are a class of error-correcting codes defined over the set of subspaces of a finite vector space. They have emerged as a powerful tool in network coding, where information is ...

Subspace is launching its parallel and real-time internet service for gaming and the metaverse on November 18. And I talked about it today with Ron Williams, chief operating officer at the company at ...

Let T be a C·0-contraction on a Hilbert space 𝓗 and 𝒮 be a non-trivial closed subspace of 𝓗. We prove that 𝒮 is a T-invariant subspace of 𝓗 if and only if there exists a Hilbert space 𝓓 and a ...

Abstract: In the non-stationary environment, compared with the traditional subspace estimation algorithm, the projection approximation subspace tracking (PAST) algorithm can achieve less computation ...

Two weeks ago, a modest-looking paper was uploaded to the arXiv preprint server with the unassuming title On the invariant subspace problem in Hilbert spaces. The paper is just 13 pages long and its ...

Abstract: We study direction-of-arrival (DOA) estimation from coarsely quantized data. We focus on a two-step approach which first estimates the signal subspace via covariance estimation and then ...
