6:00 AM | MatchLift : Near-Optimal Joint Object Matching via Convex Relaxation - implementation -
Yuxin Chen sent me the following yesterday:Dear Igor, I have been following your blog daily, and have learned a lot from your blog entries.  I believe that this definitely has made a significant impact to the community.  We have recently published one paper in ICML,  which uses ideas motivated by robust PCA / matrix completion to solve joint graph matching,  a task particularly important in computer vision and graphics. We have released sample code for the key […]

3:05 PM | What Have I Done Here?
I’ve been blogging for coming up on 6 years. Countless hundreds of pages of mostly crap, spun out over more than half a decade of sobriety and various life events. A divorce. A career involving two jobs a thousand miles apart. Some academic successes. Some failures. Physical and emotional changes. A new romance. Life. But […]

10:55 AM | CVXPY: A Python-Embedded Modeling Language for Convex Optimization Problems - implementation -
  Following up on yesterday's Domain Specific Languages (DSL) for Convex Optimization here is CVXPY, an effort to implement it in Python. From the page: CVXPY is a Python-embedded modeling language for convex optimization problems. It allows you to express your problem in a natural way that follows the math, rather than in the restrictive standard form required by solvers.....CVXPY is a Python-embedded modeling language for convex optimization problems. It allows you to […]

5:53 PM | Convex Optimization in Julia
Everybody that has read this blog a few times knows our collective reliance on CVX as a means of figuring out, in small problems, if things work out. While CVX is a great tool it relies on Matlab which is not free. As nice as Matlab is, some people want to have CVX capabilities outside of that framework. Today and tomorrow, we will feature two instances of that. The first one is an implementation in Julia.  Convex Optimization in Julia by Madeleine Udell, Karanveer Mohan, David Zeng, Jenny […]
