kandi X-RAY | ceres Summary

ceres is a Python library typically used in Database, Time Series Database applications. ceres has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can install using 'pip install ceres' or download it from GitHub, PyPI.

Ceres is a time-series database format intended to replace Whisper as the default storage format for Graphite. In contrast with Whisper, Ceres is not a fixed-size database and is designed to better support sparse data of arbitrary fixed-size resolutions. This allows Graphite to distribute individual time-series across multiple servers or mounts. Expected features such as roll-up aggregation and data expiration are not provided by Ceres itself, but instead are implemented as maintenance plugins in Carbon.

            Eigen Matrix Assignment Operator with User-Defined Data Types
            Asked 2021-Jul-16 at 04:58

            I am using the Eigen matrix library to deal with matrices of std::complex data types, where T is either of type double or of type ceres::Jet. Eigen documentation indicates that << is the correct operator to use for assignment, but it seems that << is not overloaded for matrices of user-defined data types. Is there a different method I can use to initialize Eigen matrices that works for both data types?

            ANSWER

            Answered 2021-Jul-16 at 04:58

            The problem with your code is not that Eigen is not overloaded for matrices of user-defined type (it is) but that you have a nested template argument of the type Eigen::Matrix, Eigen::Dynamic, Eigen::Dynamic> (where T is something like ceres::Jet resulting in Eigen::Matrix>, Eigen::Dynamic, Eigen::Dynamic>). You will have to explicitly construct the elements of the nested type T before using the streaming operator <<.

            Ceres Solver: how to define bounds/constraints?
            Asked 2021-Jun-04 at 12:31

            Ceres solver states everywhere that it can

            [...] solve robustified bounds constrained non-linear least squares problems

            and that it supports upper and lower bounds constraints on the parameter blocks (for example in http://ceres-solver.org/modeling_faqs.html it states Ceres Solver only supports upper and lower bounds constraints on the parameter blocks), but somehow I can't find anywhere in the documentation how I can set these upper and lower bounds.

            So, how do I set upper and lower bounds for parameter blocks in ceres solver?

            Specifically, how do I do that in an AutoDiffCostFunction? If I use if statements to return a very big residual out of bounds, then that function isn't differentiable.

            For example, this is the ceres Hello World:
