What’s Your Story: Weishung Liu

In this episode, I’m talking with Principal PM Manager Weishung Liu. Wei has used her love of storytelling and interest in people and their motivations to deliver meaningful products and customer experiences. This includes the creation of a successful line of Disney plush toys and contributions to the satellite internet system Starlink. With Microsoft, she helped develop Watch For, a real-time video analytics platform that has gone on to enhance gaming via streaming highlights and to support content moderation in […]

Beginning Data Science (7-day mini-course)

Data science uses mathematics to analyze data, distill information, and tell a story. The result of data science may be just to rigorously confirm a hypothesis, or to discover some useful property from the data. There are many tools you can use in data science, from basic statistics to sophisticated machine learning models. Even the most common tool can work wonderfully in a data science project. In this 7-part crash course, you will learn from examples how to perform a […]

Tips for Deploying Machine Learning Models Efficiently

Image created by Author using Midjourney Introduction The process of deploying machine learning models is an important part of deploying AI technologies and systems to the real world. Unfortunately, the road to model deployment can be a tough one. The process of deployment is often characterized by challenges associated with taking a trained model — the culmination of a lengthy data-preparation and model-training process — to the world at-large, where it must continue to perform well. These challenges arise as […]

What Are CRUD Operations?

The idea of CRUD is strongly connected with databases. That’s why it’s no surprise that CRUD operations correspond almost one-to-one with SQL commands: When you create data, you’re using the INSERT command to add new records to a table. After creation, you may read data using SELECT. With a SELECT query, you’re asking the database to retrieve the specific pieces of information you need, whether it’s a single value, a set of records, or complex relationships between data points. The […]

Efficient Iterations With Python Iterators and Iterables

Python’s iterators and iterables are two different but related tools that come in handy when you need to iterate over a data stream or container. Iterators power and control the iteration process, while iterables typically hold data that you want to iterate over one value at a time. Iterators and iterables are fundamental components of Python programming, and you’ll have to deal with them in almost all your programs. Learning how they work and how to create them is key […]

How to Create Pivot Tables With pandas

A pivot table is a data analysis tool that allows you to take columns of raw data from a pandas DataFrame, summarize them, and then analyze the summary data to reveal its insights. Pivot tables allow you to perform common aggregate statistical calculations such as sums, counts, averages, and so on. Often, the information a pivot table produces reveals trends and other observations your original raw data hides. Pivot tables were originally implemented in early spreadsheet packages and are still […]

Tips for Handling Imbalanced Data in Machine Learning

Image created by Author using Midjourney Introduction Imperfect data is the norm rather than the exception in machine learning. Comparably common is the binary class imbalance when the classes in a trained data remains majority/minority class, or is moderately skewed. Imbalanced data can undermine a machine learning model by producing model selection biases. Therefore in the interest of model performance and equitable representation, solving the problem of imbalanced data during training and evaluation is paramount. This article will define imbalanced […]
