A tutorial on training a DarkNet YOLOv4 model for the CrowdHuman dataset

YOLOv4 CrowdHuman Tutorial This is a tutorial demonstrating how to train a YOLOv4 people detector using Darknet and the CrowdHuman dataset. Setup If you are going to train the model on Google Colab, you could skip this section and jump straight to Training on Google Colab. Otherwise, to run training locally, you need to have a x86_64 PC with a decent GPU. For example, I mainly test the code in this repository using a desktop PC with: NVIDIA GeForce RTX […]

A toolbox that allows to train and evaluate deep learning models

Ludwig Ludwig is a toolbox that allows users to train and test deep learning models without the need to write code. It is built on top of TensorFlow. To train a model you need to provide is a file containing your data, a list of columns to use as inputs, and a list of columns to use as outputs, Ludwig will do the rest. Simple commands can be used to train models both locally and in a distributed way, and […]

A Python package for multiply imputing missing data using deep learning methods

MIDASpy MIDASpy is a Python package for multiply imputing missing data using deep learning methods. The MIDASpy algorithm offers significant accuracy and efficiency advantages over other multiple imputation strategies, particularly when applied to large datasets with complex features. In addition to implementing the algorithm, the package contains functions for processing data before and after model training, running imputation model diagnostics, generating multiple completed datasets, and estimating regression models on these datasets. Background and suggested citation For more information on MIDAS, […]

Python3 library for multimedia functions at the command terminal

TERMINEDIA This is a Python library allowing using a text-terminal as a low-resolution graphics output, along with keyboard realtime reading, and a couple utilities enough to enable using a text terminal to run simple 2D games or simply rich terminal apps. The “noveau” factor is that it uses Unicode quarter-character block combinations to effectivelly enable 1/4 character “pixels” in the terminal. It also makes use of 24bit “true” color for text, not limiting itself to the 80’s 8 color palette […]
