A Python Library for Time Series using Hidden Markov Models.

Let me introduce you to hmmlearn. Image
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 themselvesImage
2. HMM for Time Series with hmmlearn

hmmlearn implements the Hidden Markov Models (HMMs).

We can use HMM for time series. Example: Using HMM to understand earthquakes.

🚨NEW AI for Data Scientists Workshop

This is what's coming: Image
Generative AI is the future of Data Science.

Those who can build with LLMs and Python have unlimited career potential. Image
To help, I'm going to lift the curtains on one of my BEST AI projects that companies will pay you $$$ for.

Here's what I'll share in the training: Image

❌Move over PowerBI. There's a new AI analyst in town.

💡Introducing ThoughtSpot. Image
1. AI Analyst

ThoughtSpot’s Spotter is an AI analyst that uses generative AI to answer complex business questions in natural language, delivering visualizations and insights instantly.

It supports iterative querying (e.g., “What’s next?”) without predefined dashboards. Image
2. Self-Service Analytics

Unlike Tableau and Power BI, which rely on structured dashboards, ThoughtSpot emphasizes self-service analytics with a search-based interface, making it accessible to non-technical users.

Its AI-driven approach feels like “ChatGPT for data.” Image

Top 7 most important statistical analysis concepts that have helped me as a Data Scientist.

This is a complete 7-step beginner ROADMAP for learning stats for data science. Let's go: Image
Step 1: Learn These Descriptive Statistics

Mean, median, mode, variance, standard deviation. Used to summarize data and spot variability. These are key for any data scientist to understand what’s in front of them in their data sets. Image
2. Learn Probability

Know your distributions (Normal, Binomial) & Bayes’ Theorem. The backbone of modeling and reasoning under uncertainty. Central Limit Theorem is a must too. Image

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

Introducing Docling. Here's what you need to know: 🧵 Image
1. What is Docling?

Docling is a Python library that simplifies document processing, parsing diverse formats — including advanced PDF understanding — and providing seamless integrations with the gen AI ecosystem. Image
2. Document Conversion Architecture

For each document format, the document converter knows which format-specific backend to employ for parsing the document and which pipeline to use for orchestrating the execution, along with any relevant options. Image

The concept that helped me go from bad models to good models: Bias and Variance.

In 4 minutes, I'll share 4 years of experience in managing bias and variance in my machine learning models. Let's go. 🧵 Image
1. Generalization:

Bias and variance control your models ability to generalize on new, unseen data, not just the data it was trained on. The goal in machine learning is to build models that generalize well. To do so, I manage bias and variance. Image
2. Low vs High Bias:

Models with low bias are usually complex and can capture the underlying patterns in data very well. They are flexible enough to fit the training data closely. Models with high bias are overly simple and cannot capture the complexity in the data. They often underfit the training data, meaning they perform poorly even on the data they were trained on.Image
