About your data science tutor
HeY! I’m Yeriko. I teach Python, statistics, and machine learning by building real, high-impact projects — not just theory. We work with sound, video, and real datasets so concepts actually stick and translate into real skills. I’ve built models at Ford Motor Company and Chrysler, and I bring that same production-level thinking into every session. This isn’t “tutorial-style” learning. This is how data science actually works in the real world. Here, you won’t just code, you’ll learn how to: Think like a data scientist Structure messy data into usable systems Build models that actually solve problems Communicate insights like a pro From predictive modeling to full ML pipelines, everything is broken down in a way that’s clear, practical, and immediately usable — no fluff, no confusion. One example: I’ve built a music recommendation system that treats audio as structured data. Instead of guessing songs, the system extracts features like energy, texture, and dynamics using signal processing, then uses PCA + clustering to organize tracks into “states.” From there, it selects the next track using similarity scoring + constraints like BPM, key, and energy flow — essentially modeling how a DJ thinks, but powered by machine learning. That’s the core idea: take something complex → break it into data → build an intelligent system around it. On top of that, I’m strong in SQL and tools like Tableau, so we go beyond modeling — we cover the full pipeline: data extraction → transformation → modeling → visualization → decision-making.

Data Science concepts taught by Yeriko
The Student presented their WordPress website, detailing specific requirements for mobile optimization of H1 headings, integration of Amazon affiliate banners, and removal of embedded theme text from image banners. The Tutor provided an initial assessment and outlined a plan to implement these web development and design changes, with a follow-up session scheduled to transfer the updated files.
Amazon Affiliate Banner Integration
User Experience (UX) & Design Refinements
Website Performance & SEO Foundations
WordPress Theme Customization & Content Management
Mobile Responsiveness: H1 Headings & Centering
The Student and Tutor engaged in a wide-ranging discussion covering principles of aerodynamics, the application of AI and statistics in fields like rocketry and medical diagnostics, and personal data tracking for self-improvement. The Student also demonstrated and explained techniques for playing complex drum rhythms. They made plans to cover Python and app development in their next session.
Rocket Nozzle Fluid Dynamics & Optimization
Outliers: Rethinking Deviations in Data & Society
Personal Data Analytics for Self-Optimization
Data-Driven AI & Predictive Modeling
Exponential Growth & Focused Skill Development
Statistics as a Framework for Experimentation & Proof
The Student and Tutor engaged in a comprehensive discussion on core Data Science concepts, including data normalization, different types of statistical distributions, and the classification of variables. They explored the stages of Exploratory Data Analysis (EDA), covering data imputation methods and the significance of residuals in statistical modeling. The session also introduced the foundational principles of Artificial Intelligence, explaining its operational mechanics through the analogy of neurons and discussing its real-world applications. The Student expressed interest in learning about optical recognition and applying these concepts to personal data analysis for self-improvement, which was noted for future lessons.
Exploratory Data Analysis (EDA) & Imputing Missing Data
Data Normalization and Distributions
Introduction to Artificial Intelligence (AI) and Neural Networks
Residuals and Data Variance
Categorical vs. Numerical Variables & Predictive Models
The session covered setting up Python virtual environments to manage project dependencies and avoid conflicts with system-level installations. The student learned how to create, activate, and manage virtual environments, as well as how to export and import package lists for different machines. Homework includes practicing the virtual environment setup and exploring data analysis using the new environment.
Creating and Activating a Virtual Environment
Virtual Environments in Python
Importing Data and Calculating Portfolio Returns
Terminal Usage for Python Development
Package Management with Pip
Exporting and Replicating Environments (requirements.txt)
The Tutor and Student explored statistical concepts including linear regression, correlation, and probability distributions. They practiced analyzing data relationships using correlation matrices and discussed hypothesis testing with examples. The next session is planned to involve more complex datasets and examples.
Null Hypothesis and p-values
Correlation: Measuring Relationships
Linear Regression Basics
Distributions: The Shape of Data
The Tutor and Student collaborated on designing a system for tracking dealer training attendance and knowledge retention for M&A Supply. They discussed data structure, ID management, and the use of AI-generated content and potential dashboards to improve training effectiveness. The next steps involve the Student creating a system template based on the discussed data and concepts.
