    BEDS - Bed Evaluation & Design System

    A system for designing and evaluating patient flow in hospitals.

    BEDS evaluates patient flow in hospitals. Specifically, BEDS evaluates the occupancy of beds and the probability of receiving a bed on arrival to the hospital. BEDS is built on the assumption that patients arrive with a stationary intensity, and that the distribution governing their length-of-stay is also stationary. Thus, BEDS works only when modeling inpatient wards. BEDS further assumes a setup consisting of a number of patient types and wards. The wards contain a fixed capacity....

    Lisp Koans

    Lisp Koans

    Common Lisp Koans is a language learning exercise

    Lisp Koans is a self-guided learning path for Common Lisp that teaches the language’s idioms through a series of failing tests you progressively make pass. Each koan introduces a concept—symbols, lists, macros, multiple dispatch, reader syntax—then asks you to fill in the blanks and run the suite again. The feedback loop is intentionally tight: fail, reflect, fix, and rerun until the tests become a form of living documentation. Because koans are organized from fundamentals to...

    AllenNLP

    AllenNLP

    An open-source NLP research library, built on PyTorch

    ...AllenNLP supports loading "plugins" dynamically. A plugin is just a Python package that provides custom registered classes or additional allennlp subcommands. There is ecosystem of open source plugins, some of which are maintained by the AllenNLP team here at AI2, and some of which are maintained by the broader community. AllenNLP will automatically find any official AI2-maintained plugins that you have installed, but for AllenNLP to find personal or third-party plugins you've installed, you also have to create either a local plugins file named .allennlp_plugins in the directory where you run the allennlp command.
