PyMC3
Probabilistic programming in Python
PyMC3 allows you to write down models using an intuitive syntax to describe a data generating process. Fit your model using gradient-based MCMC algorithms like NUTS, using ADVI for fast approximate inference — including minibatch-ADVI for scaling to large datasets, or using Gaussian processes to build Bayesian nonparametric models. PyMC3 includes a comprehensive set of pre-defined statistical distributions that can be used as model building blocks. Sometimes an unknown parameter or variable in a model is not a scalar value or a fixed-length vector, but a function. A Gaussian process (GP) can be used as a prior probability distribution whose support is over the space of continuous functions. PyMC3 provides rich support for defining and using GPs. Variational inference saves computational cost by turning a problem of integration into one of optimization. PyMC3's variational API supports a number of cutting edge algorithms, as well as minibatch for scaling to large datasets. -

Guide to Open Source UML Tools
Open source UML tools are typically programs available to users at no cost and can be modified by anyone who has access to the source code. These types of tools allow users greater freedom and flexibility when constructing, designing, analyzing, and maintaining diagrams related to Unified Modeling Language (UML). Various types of UML include uses cases, class diagrams, activity diagrams, sequence diagrams, state machines, etc.
Using an open source UML tool typically requires very little in terms of hardware specifications. The majority of these tools provide support for most common desktop operating systems such as Windows or macOS as well as Linux-based distributions. Open source UML tools also usually contain all the necessary features that you would expect from a standard modeling language such as drag-and-drop components for creating models quickly and easily. Many open source UML tools also allow for collaborative work on projects which allows multiple people with varied experience levels to work together in real time and contribute their own ideas to the process.
In addition to being free and user friendly often times many open source UML tools contain plug-ins that expand upon the provided features allowing users even more customization capabilities depending on their needs. Furthermore many of these plugins extend support beyond just basic modelling into areas like code engineering which can allow existing code bases to be visually represented through various graphical elements such as sequence diagrams making analysis easier than ever before.
The benefits of using an open source UML tool to create various models are numerous far ranging from cost savings due not needing any proprietary software license fees all the way up too improved collaboration opportunities among companies when working on joint projects over long distances without ever having met face-to-face in person; overall it is hard to argue against using this type of technology when developing applications or services on a budget while still getting professional quality results in a timely manner every single time.
Features Offered by Open Source UML Tools

How To Get Started With Open Source UML Tools
Getting started with open source UML tools is easy and can be done in a few steps. First, pick an open source UML tool that best fits your project needs. This could range from tools like ArgoUML to Visual Paradigm Community Edition to StarUML and more. These tools are available for download online for free, so look around and find the one that works best for you. After that, familiarize yourself with the tool's terminology, functionalities and interface. Most of these tools are reasonably intuitive to grasp but there may still be some learning curve involved depending on how experienced you are with working on diagrams or programs of this kind.
Once you have the basics down of your chosen tool, it's time to start drawing out your models. Start off by understanding the different types of UML diagrams that exist such as class diagrams, sequence diagrams, activity diagrams and more—each one will allow you to communicate/model different aspects of your software/system design differently so decide which ones will serve you best for what purpose. Once you've decided on one or multiple diagram types to work with, dive in and begin making them with what your open source UML tool provides - create classes using shapes like rounded rectangles or nodes if needed; use arrows or plugs & sockets to show associations between elements; add notes or comments when necessary etcetera – things should become easier gradually as you move along due to repeated exposure.
Finally, review what has been created so far – make sure all relevant information exists in each element/diagram; take some time away from it then come back later to see if any changes need to be made; discuss it together (if possible) with other members who have experience in creating UML models etcetera before finally moving forward into implementation phase which involves going against the same process but at code level (if such is required). And there you go. You're now all set up and ready to go with creating awesome software designs through open source UML tools.
