Computer Vision

An all-in-one toolkit for computer vision

Introduction EasyCV is an all-in-one computer vision toolbox based on PyTorch, mainly focus on self-supervised learning, image classification, metric-learning, object detection and so on. Major features SOTA SSL Algorithms EasyCV provides state-of-the-art algorithms in self-supervised learning based on contrastive learning such as SimCLR, MoCO V2, Swav, DINO and also MAE based on masked image modeling. We also provides standard benchmark tools for ssl model evaluation. Vision Transformers EasyCV aims to provide plenty vision transformer models trained either using supervised learning […]

Music controller plugin for Steam OS

This is very WIP plugin for adding the native (MPRIS) media controls to the SteamOS Plugin Loader. Changes Required to the Plugin Loader To load the plugin, I had to do the following changes to the plugin_loader.service from the Plugin Loader in order to be able to connect to the User’s info instead of the Root’s. Hopefully this won’t be required for future versions [Service] User=deck Group=deck Environment=DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus … GitHub View Github

MetricFlow allows you to define, build, and maintain metrics in code

Welcome to MetricFlow MetricFlow is a computational framework for building and maintaining consistent metric logic. The name comes from the approach taken to generate metrics. Using the user-defined semantic model, a query is first compiled into a metric dataflow plan. The plan is then converted to an abstract SQL object model, optimized, then rendered to engine-specific SQL. MetricFlow provides a set of abstractions that help you construct complicated logic and aggregate metrics to a range of granularities. As a developer […]

Speeding up software with faster hardware: tradeoffs and alternatives

If you’re writing software to process data, you will often hit performance problems: batch jobs that run too slowly, or use too much memory. One potential solution is purchasing better hardware. With cloud computing, switching to a computer with more cores, or adding more RAM, can be done in a few minutes, or even just a few seconds. But as with any solution, there are tradeoffs involved. If your first solution to any performance problem is spending more money on […]

A modern pure-Python library for reading PDF files

A modern pure-Python library for reading PDF files. The goal is to have a modern interface to handle PDF files which is consistent with itself and typical Python syntax. The library should be Python-only (hence no C-extensions), but allow to change the backend. Similar in concept to matplotlib backends and Keras backends. The default backend could be PyPDF2. Possible other backends could be PyMuPDF (using MuPDF) and PikePDF (using QPDF). WARNING: This library is UNSTABLE at the moment! Expect many […]

Private Prediction Market for Starknet

Basic Idea A and B can enter into a bet by staking some token(ERC20-compliant) – lets say they bet on the price of ETH after 1 month, so we setup a callback with an oracle asking it to give the results to the protocol after the stipulated time, and whoever wins gets to keep the full staked amount – this can then be extended to arbitrary number of participants – we can also create an NFT to represent the position […]
