In this work we define and use a quantum version of EM to fit a Gaussian Mixture Model.

Quantum algorithms for Second-Order Cone Programming and Support Vector Machines

no code implementations19 Aug 2019 Iordanis Kerenidis, Anupam Prakash, Dániel Szilágyi

We present a quantum interior-point method (IPM) for second-order cone programming (SOCP) that runs in time $\widetilde{O} \left( n\sqrt{r} \frac{\zeta \kappa}{\delta^2} \log \left(1/\epsilon\right) \right)$ where $r$ is the rank and $n$ the dimension of the SOCP, $\delta$ bounds the distance of intermediate solutions from the cone boundary, $\zeta$ is a parameter upper bounded by $\sqrt{n}$, and $\kappa$ is an upper bound on the condition number of matrices arising in the classical IPM for SOCP.

q-means: A quantum algorithm for unsupervised machine learning

2 code implementations NeurIPS 2019 Iordanis Kerenidis, Jonas Landman, Alessandro Luongo, Anupam Prakash

For a natural notion of well-clusterable datasets, the running time becomes $\widetilde{O}\left( k^2 d \frac{\eta^{2. 5}}{\delta^3} + k^{2. 5} \frac{\eta^2}{\delta^3} \right)$ per iteration, which is linear in the number of features $d$, and polynomial in the rank $k$, the maximum square norm $\eta$ and the error parameter $\delta$.
