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.

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.
