This is Yiqiao Yin, and welcome to my personal site.
Personal Background:
I have been in the AI/ML space since 2015, leading all forms of AI-backed solutions including but not limited to Computer Vision, Natural Language Models (NLP), and most recently Large Language Models (LLMs) and Generative AI. I am currently a Tech Lead at Vertex Inc, a global leading provider of tax technologies 📊💻.
Previously, I was a Senior ML Engineer at an S&P 500 company, LabCorp, developing AI-driven solutions 🧠💻 in drug diagnostics, drug development, operations management, and financial decisions for our global leaders in life sciences 🌍🔬 (see Labcorp SEC filings here).
I have also held positions such as enterprise-level Data Scientist at Bayer (a EURO STOXX 50 company), Quantitative Researcher (apprenticeship) at AQR (a global hedge fund pioneering in alternative quantitative strategies to portfolio management and factor-based trading), and Equity Trader at T3 Trading on Wall Street (where I was briefly licensed Series 56 by FINRA).
I supervise a small fund specializing in algorithmic trading (since 2011, performance is here) in equity market, cryptocurrencies, and real estate investment. I also run my own monetized YouTube Channel.
Feel free to add me on LinkedIn. 🚀📈
At leisure, I run W.Y.N. Associates, LLC, a registered legal entity in the state of New York, to pilot and drive for-profit personal passion projects.

When it comes to filtering stocks using Carhart's 4-factor model (see this paper, an algorithmic trading strategy based on the famous Fama-French 3-factor model), investors can identify potential investment opportunities by examining four key factors that have been shown to explain a significant portion of the variation in stock returns. These factors include market risk, size, value, and momentum. The momentum factor, in simple terms, refers to the tendency of stocks that have recently performed well to continue performing well in the near future, and vice versa for stocks that have recently underperformed. Essentially, momentum is the measure of a stock's recent price trend, with strong upward trends indicating positive momentum and strong downward trends indicating negative momentum.

AI4ALL: General Machine Learning and Artificial Intelligence FREE Sources
The Fundamentals in Machine Learning | Link | This is an introduction course of machine learning: The Fundamentals of Machine Learning. The course will cover a wide range of topics to teach you step by step from handling a dataset to model delivery. The course assumes no prior knowledge of the students. However, some prior training in python programming and some basic calculus knowledge is definitely helpful for the course. The expectation is to provide you the same knowledge and training as that is provided in an intro Machine Learning or Artificial Intelligence course at a credited undergraduate university computer science program.
Fundamentals in Neural Networks | Link | Deep learning (also known as deep structured learning) is part of a broader family of machine learning methods based on artificial neural networks with representation learning. Learning can be supervised, semi-supervised or unsupervised. Deep-learning architectures such as deep neural networks, deep belief networks, deep reinforcement learning, recurrent neural networks and convolutional neural networks have been applied to fields including computer vision, speech recognition, natural language processing, machine translation, bioinformatics, drug design, medical image analysis, material inspection and board game programs, where they have produced results comparable to and in some cases surpassing human expert performance. This course covers the following three sections: (1) Neural Networks, (2) Convolutional Neural Networks, and (3) Recurrent Neural Networks.
Basics in Artificial Neural Networks | Link | The course introduces the fundamental building blocks of an Artificial Neural Network (ANN) model. With ANN being the leading milestone, the course lays the ground work for the audience into the field of Representation Learning.
Basics in Convolutional Neural Networks | Link | The course expands from ANN and introduces the fundamental building blocks of a Convolutional Neural Network (CNN). Advanced CNN models are also introduced to lead audience to the field of Representation Learning.
Image-to-Image Network Models | Link | The course investigates a higher level of network models that learn the intrinsic representation of image data. Such models learn to produce images rather than annotations or labels, which is different from previous courses. The materials lead the audience into the field of unsupervised learning.
Natural Language Processing | Link | The course investigates machine intelligence on language interpretations. Moreover, we investivate deep recurrent network models to study and potentially make predictions using language as input.
