Since we will be using PyTorch for model training, we need to convert our categorical and numerical columns to tensors.Let's first convert the categorical columns to tensors. In PyTorch, tensors can be created via the numpy arrays. We will first convert data in the four categorical columns...
Implementation of Vision Transformer, a simple way to achieve SOTA in vision classification with only a single transformer encoder, in Pytorch. Significance is further explained in Yannic Kilcher's video. There's really not much to code here, but may as well lay it out for everyone so we ...

The classification model was trained using Python (version 3.6.8) and PyTorch (version 1.7.1). The method was evaluated through three datasets: the hyperspectral dataset, the RGB image dataset, and the fused dataset. Each dataset consists of four classes of VS with varying freshness levels. ...
It is faster than the classical machine learning libraries PyTorch and Tensorflow if one observation at a time must be labeled, but ref. [88] claim that it is slower than MOA, since Java code is expected to run faster than Python code. Finally, we discuss the most frequently cited ...
In this subsection, we provide detailed information about the conducted experiments, such as experimental setup, baseline methods, and evaluation metrics. Experimental setup We formulated the baseline and proposed methods using Python version 3.6.9 and PyTorch library version 1.4.0. We initialized the ...

The aim of this repository is to show a baseline model for text classification through convolutional neural networks in the PyTorch framework. The architecture implemented in this model was inspired by the one proposed in the paper: Convolutional Neural
