Saving memory with Pandas 1.3’s new string dtype

When you’re loading many strings into Pandas, you’re going to use a lot of memory. If you have only a limited number of strings, you can save memory with categoricals, but that’s only helpful in a limited number of situations. With Pandas 1.3, there’s a new option that can save memory on large number of strings as well, simply by changing to a new column type. Let’s see how. Pandas’ different string dtypes Every pandas.Series, and every column in a […]

Command-line Tools

view RedFlagDeals.com from the command line in python

RFD This is a CLI utility that allows you to view RedFlagDeals.com on the command line. Motivation It is often faster to use a CLI than to load up a web page and navigate web elements. This tool can search for deals and sort them based on score and views. It is also able to load entire threads (without pagination) for additional analysis. Installation :information_source: python2 may still work but it is no longer supported. python3 -m pip install –user […]

Minimal implementation of PAWS in TensorFlow

PAWS-TF Implementation of Semi-Supervised Learning of Visual Features by Non-Parametrically Predicting View Assignments with Support Samples (PAWS) in TensorFlow (2.4.1). PAWS introduces a simple way to combine a very small fraction of labeled data with a comparatively larger corpus of unlabeled data during pre-training. With its approach, it sets the state-of-the-art in semi-supervised learning (as of May 2021) beating methods like SimCLRV2, Meta Pseudo Labels that too with fewer parameters and a smaller pre-training schedule. For details, I recommend checking […]

Vision Transformer for Fast and Efficient Scene Text Recognition

deep-text-recognition-benchmark ViTSTR is a simple single-stage model that uses a pre-trained Vision Transformer (ViT) to perform Scene Text Recognition (ViTSTR). It has a comparable accuracy with state-of-the-art STR models although it uses significantly less number of parameters and FLOPS. ViTSTR is also fast due to the parallel computation inherent to ViT architecture. ViTSTR is built using a fork of CLOVA AI Deep Text Recognition Benchmark whose original documentation is at the bottom. Below we document how to train and evaluate […]
