Testing

Visual, reactive testing library for Julia

PlutoTest.jl (alpha release) A macro @test that you can use to verify your code’s correctness. But instead of just saying “Pass” or “Fail”, let’s try to show you why a test failed. ✨ time travel ✨ to replay the execution step-by-step ⭐️ multimedia display ⭐️ to make results easy to read Try this demo in your browser First, update Pluto to at least 0.14.5! Next, add this package like so: julia> import Pkg; Pkg.add(Pkg.PackageSpec(url=”https://github.com/JuliaPluto/PlutoTest.jl”)) julia> using PlutoTest julia> @test 1 […]

Use AI to generate a optimized stock portfolio

AIPortfolio Logo Use AI, Modern Portfolio Theory, and Monte Carlo simulation’s to generate a optimized stock portfolio that minimizes risk while maximizing returns. How does it work? The app works by pulling the stock close data from the yahoo finance api. We then calculate the log returns and the volitility of the data to see what the overall trend for the stocks look like. We then generate random portfolio weights and use scipy to maximize a function that calculates the […]

A Neural Algorithm of Artistic Style implementation – Neural Style Transfer

ArtiStyle To quote authors Leon A. Gatys, Alexander S. Ecker, Matthias Bethge, “in light of the striking similarities between performance-optimised artificial neural networks and biological vision, our work offers a path forward to an algorithmic understanding of how humans create and perceive artistic imagery. The idea of Neural Style Transfer is taking a white noise as an input image, changing the input in such a way that it resembles the content of the content image and the texture/artistic style of […]

What they do when in doubt: a study of inductive biases in seq2seq learners

Abstract Sequence-to-sequence (seq2seq) learners are widely used, but we still have only limited knowledge about what inductive biases shape the way they generalize. We address that by investigating how popular seq2seq learners generalize in tasks that have high ambiguity in the training data. We use four new tasks to study learners’ preferences for memorization, arithmetic, hierarchical, and compositional reasoning. Further, we connect to Solomonoff’s theory of induction and propose to use description length as a principled and sensitive measure of […]

AIML – A Language for Chatbots

This article was published as a part of the Data Science Blogathon. What is a Chatbot? Chatbots are intelligent digital assistants which may address customer’s basic and predictable queries. They offer numerous services via chatting and perform basic customer service operations. Chatbots work 24/7 and hence they provide assistance when offices are closed on holidays. There are a variety of synonyms for chatbot, including “talkbot,” “bot,” “IM bot,” “interactive agent” or “artificial conversation entity.“ Most organizations have already started implementing […]

Turn xarray timestacks into GIFs with python

GeoGIF Make GIFs from time-stacked xarray.DataArrays (time, [optional band], y, x), dead-simple. from geogif import gif, dgif gif(data_array) dgif(dask_data_array).compute() The “geo” part is a lie, actually. The arrays don’t have to be geospatial in nature. But I called it GeoGIF because: Wanting to animate a time-stack of imagery (like you’d get from stackstac) is a common task in the earth-observation/geospatial world. I think GeoGIF is a hilarious idea1. 1: To ruin the joke, it sounds like GeoTIFF, a ubiquitous geospatial […]

A Python library for the development of multimedia applications like video games

pygame pygame is a free and open-source cross-platform library for the development of multimedia applications like video games using Python. It uses the Simple DirectMedia Layer library and several other popular libraries to abstract the most common functions, making writing these programs a more intuitive task. Installation pip install pygame Help If you are just getting started with pygame, you should be able to get started fairly quickly. Pygame comes with many tutorials and introductions. There is also full reference […]
