Data augmentation is a key technology in the field of artificial intelligence and machine learning. It involves creating variations on existing datasets to improve model performance and generalization. Python is a popular AI and ML language that provides several powerful data augmentation libraries. In this article, we will introduce ten Python libraries for data augmentation and provide code snippets and explanations for each library.
Augmentor
##Augmentor is a general-purpose Python library for image enhancement. It allows you to easily apply a range of operations to your images, such as rotation, flipping, and color manipulation. Here is a simple example of how to use Augmentor for image enhancement:
import Augmentor p = Augmentor.Pipeline("path/to/your/images") p.rotate(probability=0.7, max_left_rotatinotallow=25, max_right_rotatinotallow=25) p.flip_left_right(probability=0.5) p.sample(100)
Albumentations
Albumentations Master supports various enhancement features such as random rotation , flip and brightness adjustment. He is one of my most commonly used enhancement libraries
import albumentations as A transform = A.Compose([A.RandomRotate90(),A.HorizontalFlip(),A.RandomBrightnessContrast(), ]) augmented_image = transform(image=image)["image"]
Imgaug
##Imgaug is a library for enhancing images and videos. It provides a wide range of enhancements, including geometric transformations and color space modifications. Here is an example using Imgaug:import imgaug.augmenters as iaa augmenter = iaa.Sequential([iaa.Fliplr(0.5),iaa.Sometimes(0.5, iaa.GaussianBlur(sigma=(0, 2.0))),iaa.ContrastNormalization((0.5, 2.0)), ]) augmented_image = augmenter.augment_image(image)
nlpaaug is a library specifically designed for text data enhancement. It provides various techniques for generating text variations, such as synonym substitution and character-level substitution.
import nlpaug.augmenter.word as naw aug = naw.ContextualWordEmbsAug(model_path='bert-base-uncased', actinotallow="insert") augmented_text = aug.augment("This is a sample text.")
imgauge is a lightweight library focused on image enhancement. It's easy to use and offers operations like rotation, flipping, and color adjustment.
from imgaug import augmenters as iaa seq = iaa.Sequential([iaa.Fliplr(0.5),iaa.Sometimes(0.5, iaa.GaussianBlur(sigma=(0, 2.0))),iaa.ContrastNormalization((0.5, 2.0)), ]) augmented_image = seq(image=image)
##TextAttack is a Python library for enhancing and attacking natural language processing (NLP) models. It provides various transformations to generate adversarial examples for NLP tasks. Here’s how to use it:
from textattack.augmentation import WordNetAugmenter augmenter = WordNetAugmenter() augmented_text = augmenter.augment("The quick brown fox")TAAE
The Text Augmentation and Adversarial Examples (TAAE) library is another tool for text enhancement . It includes techniques such as synonym substitution and sentence shuffling.
from taae import SynonymAugmenter augmenter = SynonymAugmenter() augmented_text = augmenter.augment("This is a test sentence.")Audiomentations
##Audiomentations focuses on audio data enhancement. It is an essential library for tasks involving sound processing.
import audiomentations as A augmenter = A.Compose([A.PitchShift(),A.TimeStretch(),A.AddBackgroundNoise(), ]) augmented_audio = augmenter(samples=audio_data, sample_rate=sample_rate)
ImageDataAugmentor
ImageDataAugmentor is designed for image data augmentation and works well with popular deep learning frameworks. Here's how to use it with TensorFlow:
from ImageDataAugmentor.image_data_augmentor import * import tensorflow as tf datagen = ImageDataAugmentor(augment=augmentor,preprocess_input=None, ) train_generator = datagen.flow_from_directory("data/train", batch_size=32, class_mode="binary")
Keras ImageDataGenerator
Keras provides the ImageDataGenerator class, which is used when using Keras and TensorFlow Built-in solution for image enhancement.
from tensorflow.keras.preprocessing.image import ImageDataGenerator datagen = ImageDataGenerator(rotation_range=40,width_shift_range=0.2,height_shift_range=0.2,shear_range=0.2,zoom_range=0.2,horizontal_flip=True,fill_mode="nearest", ) augmented_images = datagen.flow_from_directory("data/train", batch_size=32)
Summary
These libraries cover a wide range of data augmentation techniques for image and text data, I hope it will be helpful to you.

Google Translate adds language learning function According to Android Authority, app expert AssembleDebug has found that the latest version of the Google Translate app contains a new "practice" mode of testing code designed to help users improve their language skills through personalized activities. This feature is currently invisible to users, but AssembleDebug is able to partially activate it and view some of its new user interface elements. When activated, the feature adds a new Graduation Cap icon at the bottom of the screen marked with a "Beta" badge indicating that the "Practice" feature will be released initially in experimental form. The related pop-up prompt shows "Practice the activities tailored for you!", which means Google will generate customized
