Machine Learning: Random Forest with Python from Scratch - Accuracy and Error-1

The video tutorial introduces the concepts of error and accuracy in machine learning, explaining their significance in evaluating model performance. It details how to calculate accuracy and error rates, emphasizing the importance of minimizing error for better model performance. The tutorial also discusses the dependency of models on data and the need to select appropriate models based on accuracy and error rates. Finally, it concludes with a brief overview of the next lecture's focus on structured and unstructured data.
