Introduction​

Qlib is an AI-oriented, open-source platform from Microsoft that simplifies the entire quantitative finance process. By leveraging PyTorch, Qlib can seamlessly integrate modern neural networks—like Multi-Layer Perceptrons (MLPs)—to process large datasets, engineer alpha factors, and run flexible backtests. In this post, we focus on a PyTorch MLP pipeline for Alpha360 data in the US market, examining a single YAML configuration that unifies data ingestion, model training, and performance evaluation.

Introduction​

AdaRNN is a specialized PyTorch model designed to adaptively learn from non-stationary financial time series—where market distributions evolve over time. Originally proposed in the paper AdaRNN: Adaptive Learning and Forecasting for Time Series, it leverages both GRU layers and transfer-loss techniques to mitigate the effects of distributional shift. This article demonstrates how AdaRNN can be applied within Microsoft’s Qlib—an open-source, AI-oriented platform for quantitative finance.

Introduction​

In the realm of quantitative finance, machine learning and deep learning are revolutionizing how researchers and traders discover alpha, manage portfolios, and adapt to market shifts. Qlib by Microsoft is a powerful open-source framework that merges AI techniques with end-to-end finance workflows.

This article demonstrates how Qlib automates an AI-driven quant workflow—from data ingestion and feature engineering to model training and backtesting—using a single YAML configuration for a LightGBM model. Specifically, we’ll explore the AI-centric aspects of how qrun orchestrates the entire pipeline and highlight best practices for leveraging advanced ML models in your quantitative strategies.

Introduction

Gradient descent is a fundamental optimization algorithm used in machine learning to minimize the cost function and find the optimal parameters of a model. In the context of linear regression, gradient descent helps in finding the best-fitting line by iteratively updating the model parameters. This article delves into the mechanics of gradient descent in linear regression, focusing on how the parameters are updated and the impact of the sign of the gradient.

Introduction​

Linear regression is a fundamental algorithm in supervised machine learning, widely used for predicting continuous outcomes. It models the relationship between a dependent variable and one or more independent variables by fitting a linear equation to observed data. This article delves into the components of linear regression, explaining how inputs, parameters, and the cost function work together to create a predictive model.

Introduction​

NVIDIA's growth and innovation in the technology sector are significantly supported by its strategic partnerships with key companies in the semiconductor industry. This article provides a comparative technical analysis of several major NVIDIA partners, including Taiwan Semiconductor Manufacturing Company (TSMC), Samsung Electronics, Micron Technology, SK hynix, ASML Holding, Applied Materials, and ASE Technology.

Introduction​

In the intricate world of algorithmic trading, seamless integration between trading platforms and broker APIs is paramount.

One common issue when interfacing with Interactive Brokers (IB) API is encountering the error:

ERROR:root:Error - ReqId: 1, Code: 200, Message: No security definition has been found for the request

This error typically arises due to incorrect exchange mapping, preventing Interactive Brokers (IB) from recognizing the requested security. This article delves into the importance of accurate exchange mapping within the VeighNa trading platform, provides a detailed overview of IB's symbol rules, explains the updatePortfolio method, and offers guidance on implementing correct mappings to avoid such errors.

Introduction​

In the realm of algorithmic trading, execution algorithms play a pivotal role in optimizing trade orders to minimize market impact and slippage.
