17. Validation Set
The Validation Set is a portion of the data used to tune the model’s parameters and improve performance before testing on the test set.
18. Hyperparameters
Hyperparameters are the configuration variables that are set before the learning process begins. They influence the training process and can affect the model’s performance significantly.
19. Cross-Validation
Cross-Validation is a technique for assessing how the results of a statistical analysis will generalize to an independent dataset. It is particularly useful in validating the effectiveness of machine learning models.
20. Bias-Variance Tradeoff
The Bias-Variance Tradeoff is a central problem in supervised learning, describing the tradeoff between two types of errors that affect the model’s ability to generalize: bias (error due to overly simplistic assumptions) and variance (error due to excessive complexity).
21. Transfer Learning
Transfer Learning is a machine learning technique where a model developed for one task is reused as the starting point for a model on a second task. This approach is especially useful when there is limited data for the new task.
22. Generative Adversarial Networks (GANs)
GANs are a class of machine learning frameworks where two neural networks, a generator and a discriminator, contest with each other. The generator creating data instances while the discriminator evaluates them, thereby improving the generator’s outputs.
23. Computer Vision
Computer Vision is a field of AI that trains computers to interpret and understand the visual world. It involves empowering machines to derive meaningful information from visual inputs, facilitating activities like image and video analysis.
