Principal Component Analysis (PCA) is the gold standard in dimensionality reduction.

But almost every beginner struggles understanding how it works (and why to use it).

In 3 minutes, I'll demolish your confusion: 1. What is PCA?

PCA is a statistical technique used in data analysis, mainly for dimensionality reduction. It's beneficial when dealing with large datasets with many variables, and it helps simplify the data's complexity while retaining as much variability as possible.

K-means is one of the most powerful algorithms for data scientists.

But it's confusing for beginners. Let's fix that: 1. What is K-means?

Is a popular unsupervised machine learning algorithm used for clustering. It's a core algorithm used for customer segmentation, inventory categorization, market segmentation, and even anomaly detection.

🚨BREAKING: OpenAI just dropped a practical guide to building agents

There's a secret.

It unlocks agential workflows for data analysts, data scientists, and data engineers.

This is how: 🧵 Here are my key takeaways by section of the report specifically addressing how data professionals can use the report.

1: What Is an Agent?

Agents are LLM‑powered systems that autonomously execute multi‑step workflows on a user’s behalf—going beyond single‑turn prompts to manage tool calls, conditional logic, and goal‑based loops

90% of data scientists struggle with time series.

But all it takes is mastering 1 technique: time series decomposition.

Here's why: 1. What is Time Series Decomposition?

A statistical method used to deconstruct a time series into several components, each representing underlying patterns in the data.

There are 3 key components: Trend, Seasonal, and Residual. Let's break them down.

A Python Library for Time Series by Salesforce.

Let me introduce you to Merlion. 1. What is Merlion?

Merlion is a Python library for time series intelligence.

It provides an end-to-end machine learning framework that includes loading and transforming data, building and training models, post-processing model outputs, and evaluating model performance.

A Python Library for Time Series using Hidden Markov Models.

Let me introduce you to hmmlearn. 1. Hidden Markov Models

A Hidden Markov Model (HMM) is a statistical model that describes a sequence of observable events where the underlying process generating those events is not directly visible, meaning there are "hidden states" that influence the observed data, but you can only see the results of those states, not the states themselves

Understanding probability is essential in data science.

In 4 minutes, I'll demolish your confusion.

Let's go! 1. Statistical Distributions:

There are 100s of distributions to choose from when modeling data. Choices seem endless. Use this as a guide to simplify the choice.

Forecasting time series is what made me stand out as a data scientist.

But it took me 1 year to master ARIMA.

In 1 minute, I'll evaporate your confusion. Let's go. 1. Autoregressive Forecast Models

ARIMA and SARIMA are both statistical models used for forecasting time series data, where the goal is to predict future points in the series. The implement a concept called Autoregression.

🚨BREAKING: New Python library for agentic data processing and ETL with AI

Introducing DocETL.

Here's what you need to know: 1. What is DocETL?

It's a tool for creating and executing data processing pipelines, especially suited for complex document processing tasks.

It offers:

- An interactive UI playground
- A Python package for running production pipelines

Probability distributions are critical to data science and business decision-making.

In 3 minutes, I'll unpack 3 years of studying probability distributions (and share how I applied it to a $15,000,000 business project).

Let's go! 🧵 1. Probability Distribution Fundamentals:

In statistics, a probability distribution is a mathematical function that provides the probabilities of occurrence of different possible outcomes in an experiment. It's a way to describe how likely different outcomes will occur. There are two main types of probability distributions: Discrete and Uniform.

RIP Data Scientists.

The Generative AI Data Scientist is NOW what companies want.

This is actually good news. Let me explain: Companies are sitting on mountains of unstructured data.

PDF
Word docs
Meeting notes
Emails
Videos
Audio Transcripts

This is useful data. But it's unusable in its existing form.

🚨 BREAKING: IBM launches a free Python library that converts ANY document to data

ROC and AUC are important concepts for evaluating classification models in business (e.g. lead scoring).

In 3 minutes, I'll demystify AUC. 1. ROC Curve:

The ROC curve, which stands for the Receiver Operating Characteristic curve, is a graphical representation used to evaluate the performance of a binary classifier system as its discrimination threshold is varied.

Logistic Regression is the most important foundational algorithm in Classification Modeling.

In 2 minutes, I'll crush your confusion.

Let's dive in: 1. Logistic regression is a statistical method used for analyzing a dataset in which there are one or more independent variables that determine a binary outcome (in which there are only two possible outcomes). This is commonly called a binary classification problem.
