Course Description
Machine learning in practice requires the practitioner to understand the trade-offs between a variety of factors, both technical and non-technical. A practitioner may wish to consider trade-offs between factors like speed, accuracy, and ethics.
In order to validate a machine-learning model, there are a number of factors that need to be considered. These lessons discuss best practices in splitting the data used for modelling into a training data set and a test data set and comparing results so that common problems like overfitting can be addressed. You’ll also discover common model validation methods, model quality metrics, and common challenges.
Using pre-trained models is an important part of any machine learning practitioner’s toolkit. Pre-trained models for many important tasks like natural language processing, image recognition, and text generation can be used as part of a machine learning pipeline. These lessons discuss the advantages and disadvantages of using them in practice.
What You'll Learn
- Identify the common challenges encountered in model validation
- Assess the trade-offs between technical and non-technical factors such as speed, accuracy, and ethics
- Distinguish between underfitting and overfitting when validating a model
