Conversational AI refers to virtual agents and chatbots that mimic human interactions and can engage human beings in conversation. Using conversational AI is fast becoming a way of life - from asking Alexa to “find the nearest restaurant” to asking Siri to “create a reminder,” virtual assistants and chatbots are…
Many people are now interested in the state space model (SSM) because of how recent research has advanced. Modern SSMs, which derive from the classic state space model, benefit from concurrent training and excel at capturing long-range dependencies. Process sequence data across many activities and modalities using SSM-based methods like linear state-space layers (LSSL), structured…
Optimize your data science workflow by automating matplotlib output — with 1 line of code. Here’s how. Naming things is hard. After a long enough day, we’ve all ended up with the highly-descriptive likes of “graph7(1)_FINAL(2).png” and “output.pdf" Look familiar? We can do better — and quite easily, actually. When we use data-oriented “seaborn-esque” plotting…
Days payable outstanding is one of several key accounts payable KPIs to track and acts as a stand-in for overall operational efficiency. At its core, the DPO helps business owners and analysts determine how effectively and efficiently a company balances cash flow and vendor relations while also acting as a proxy to determine how creditworthy…

A while ago, I wrote a tutorial on writing efficient Python code. In it, I talked about using context managers and the with statement to manage resources efficiently.
I used a simple file handling example to show how files are automatically closed when the execution exits the with…
Learn how a neural network with one hidden layer using ReLU activation can represent any continuous nonlinear functions. Activation functions play an integral role in Neural Networks (NNs) since they introduce non-linearity and allow the network to learn more complex features and functions than just a linear regression. One of the most commonly used activation…
CFDI is an electronic invoicing (e-invoice) standard and related process required to conduct business in Mexico and Latin America. This article focuses on Mexico’s digital transformation program requiring CFDI-compliant electronic sales invoices instead of paper-based invoices in Mexico. What is CFDI? CFDI (Comprobante Fiscal Digital por Internet) is a government standard for conducting business in…
When working with time-series data it can be important to apply filtering to remove noise. This story shows how to implement a low-pass filter in SQL / BigQuery that can come in handy when improving ML features. Filtering of time-series data is one of the most useful preprocessing tools in Data Science. In reality, data…
