What is augmentation in CNN?

Image augmentation is one useful technique in building convolutional neural networks that can increase the size of the training set without acquiring new images. The idea is simple; duplicate images with some kind of variation so the model can learn from more examples.

What is data augmentation explain technique of data augmentation?

Data augmentation is the technique of increasing the size of data used for training a model. For reliable predictions, the deep learning models often require a lot of training data, which is not always available. Therefore, the existing data is augmented in order to make a better generalized model.

Why do we use data augmentation?

Data augmentation is useful to improve performance and outcomes of machine learning models by forming new and different examples to train datasets. Data augmentation techniques enable machine learning models to be more robust by creating variations that the model may see in the real world.

Why data augmentation is important in deep learning?

How to do data augmentation?

One common data augmentation technique is random rotation. A source image is random rotated clockwise or counterclockwise by some number of degrees, changing the position of the object in frame. Notably, for object detection problems, the bounding box must also be updated to encompass the resulting object. (We’ll discuss more about this below.)

What is data augmentation?

More in general, data augmentation is a way of adding value to data by adding additional information from internal or external sources (by analyzing the content and including the results in the the object itself for example).

What is deep learning?

Definition. Deep learning is a class of machine learning algorithms that : 199–200 uses multiple layers to progressively extract higher-level features from the raw input.

What is image augmentation?

Image Augmentation. The idea behind data augmentation (or image augmentation, when the data consists of images) is that an engineer can start with a relatively small data set, make lots of copies, and then perform interesting transformations on those copies. The end result will be a really large dataset.
