    blavaan

    blavaan

    An R package for Bayesian structural equation modeling

    ...Compilation is required; this may be a problem for users who currently rely on a binary version of blavaan from CRAN. The blavaan package depends on the lavaan package for model specification and for some computations. This means that, if you already know lavaan, then you should already be able to do many things in blavaan. In particular, many blavaan commands add the letter “b” to the start of the lavaan command. It is also sometimes possible to use a lavaan command on a blavaan object, though the results may not always be what you expect.

    StructuralEquationModels.jl

    StructuralEquationModels.jl

    A fast and flexible Structural Equation Modelling Framework

    This is a package for Structural Equation Modeling in development. It is written for extensibility, that is, you can easily define your own objective functions and other parts of the model. At the same time, it is (very) fast. We provide fast objective functions, gradients, and for some cases hessians as well as approximations thereof. As a user, you can easily define custom loss functions. For those, you can decide to provide analytical gradients or use finite difference approximation / automatic differentiation. ...

    EduData

    EduData

    Datasets in Education and convenient interface for dataset

    ...The "mature" data is in json sequence format and can be modeled by XKT and TKT(TBA) The analysis dataset tool only supports the json sequence format. To check the following statical indexes of the dataset. In order to better verify the effectiveness of the model, the dataset is usually divided into train/valid/test or using kfold method. Each item in the sequence represents one interaction. The first element of the item is the exercise id (in some works, the exercise id is not one-to-one mapped to one knowledge unit(ku)/concept, but in junyi, one exercise contains one ku) and the second one indicates whether the learner correctly answers the exercise, 0 for wrongly while 1 for correctly.

    LARA

    LARA

    Lightweight Architecture for boundedly Rational Agents

    For the purpose of policy simulation in coupled social-ecological systems (e.g. energy supply), a credible modelling of actors – especially citizens – and their decision processes is needed. This requires a framework capable of handling high numbers of heterogeneous agents (several hundreds of thousands). LARA (Lightweight Architecture for boundedly Rational Agents) meets these requirements and fills the gap between frameworks without built-in psychological foundations and full-fledged...

    Organizing the Knowledge of Humanity

    ...This project aims to make the expanse of human knowledge beautifully presentable and the exabytes of data navigable by an average user via the power of a Unified Data Model and 3d visualization layer for the Web. It will invert the top 3 layers of the OSI network model to make a 3-dimensional presentation layer with a peer-to-peer session layer for the Internet. For the curious, there is a simple demo that provides a small sense of the possibilities. Requires: VPython available here or see http://vpython.org.

    Running Reality

    Running Reality

    World history plays out down to street level on a detailed map.

    ...We at Running Reality believe that we can use the power of today's computers and mobile devices to bring history to life in an accessible, immersive, and engaging way for K-12 students, history enthusiasts, and visitors to historical sites. Running Reality gives you a map that lets you go any place on any date from 3000BC to today and explore down to the street-level of history. This model has nations and cities but also ships, armies, buildings, and people. Towns grow, buildings are constructed, ships explore new seas, and armies battle. Harbors silt in, rivers change course, and cities are sacked and burned. When you are standing at a historical site and using your mobile phone, you can see all the events that happened around you at that exact spot then zoom out to see the context of what was happening more globally.
