Steps to develop concurrence tests with Locust

In machine learning projects we often want to deploy APIs to serve the client. Before deploying an API in production, one of the things we want to check is the performance in a load test in which the API has to support several concurrent users/requests. There are many tools that allow this type of tests, Apache JMeter, K6, Gatling, Loader etc, although in many cases they involve using another programming language such as Java or JavaScript, writing the tests in XML, or they are paid tools.

Time Series Analysis and Forecasting with FB Prophet Python

In this post we will explain what time series are, and why their analysis and prediction is a particular case of Machine Learning problems. Afterwards, we will use FB Prophet to model a particular case. For that, we will use data from a shipping company with different delivery stations, where clients leave packages (letters, boxes, etc.) for their shipment. The series represents the total number of packages received each day by the whole network of stations.

Piperlab's 360-degree tour to Data Analysis: How to predict Customer Churn

In this article, we will see why data analysis is such an impactful part of any data project. Starting from a public Telco Churn dataset, we will go through the main steps to perform an insightful data analysis for every step of the project: Assessing project feasibility Assessing model performance Monitoring production models Introduction to our Customer Churn project Customer churn (also known as attrition) is defined as the amount of customers who stopped using a service in a given timeframe.

Text generation with GPT-2

1. Introduction Disclaimer: The purpose of the presentation is to make an introduction to text generation models, specifically GPT-2, and demonstrate their use. In no case is it oriented to the generation or dissemination of false information. In this post we will see how to generate text with models based on the Transformers architecture, and we will use this knowledge to demonstrate how to create fake news. The objective is to demonstrate the operation and use of these models through this practical example.

Neural Networks for Image classification: Tensorflow and Keras

1. Introduction One of the main interests of AI nowadays is computer vision. This field includes several different tasks, like image classification (i.e. classify an image as a dog or a cat), object detection (locate where exactly the dog/cat is), image segmentation (which are the pixels that belong to the object detected) and others. The applications are countless, from self-driving cars, number-plate recognition or face recognition systems to medical applications such as cancer detection and many, many more.
