Propuestas electorales de los candidatos a constituyentes, Chile 2021

textos-constituyentes propuestas electorales de los candidatos a constituyentes, Chile 2021 Programas descargados desde https://elecciones2021.servel.cl/informacion-general/ Metodología/Programación Inicialmente, bastaba con utilizar beautifulsoup + fitz en Python para descargar los archivos en formato PDF y extraer sus textos. Luego notamos que venían muchos vacíos, por corresponder a PDF escaneados (como el notable caso de una candidata del distrito 15 que subió su diploma). Para resolver este problema, recurrimos al servicio Transcribe de Amazon Cloud (con la librería boto3). GitHub https://github.com/sergiolucero/textos-constituyentes

Guide & Examples to create deep learning gstreamer plugins and use them in your pipeline

Guide & Examples to create deeplearning gstreamer plugins and use them in your pipeline Thanks to the work done by @jackersson. In this repository we have taken inspirations from: gstreamer-python gst-plugins-tf We have currently tested our code on Ubuntu 18.04. You can also refer to the official installation document for your linux flavor.

Bag-of-words vs TFIDF vectorization –A Hands-on Tutorial

This article was published as a part of the Data Science Blogathon Whenever we apply any algorithm to textual data, we need to convert the text to a numeric form. Hence, there arises a need for some pre-processing techniques that can convert our text to numbers. Both bag-of-words (BOW) and TFIDF are pre-processing techniques that can generate a numeric form from an input text. Bag-of-Words: The bag-of-words model converts text into fixed-length vectors by counting how many times each word appears. […]

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 […]
