1| ImageNet

This dataset is inspired by the growing sentiment in the image and vision research field and can be said as the de facto dataset for the classification algorithms in computer vision. This is a dataset of images that are organized according to the WordNet hierarchy.

Category: Image Processing

Dataset Info: The total number of images includes 14,197,122. The concept in WordNet is described by “synonym set” or “synset” and there are more than 100,000 synsets present in WordNet for which ImageNet provides an average of 1000 images to each synset.

Here is a link to a paper that implemented this dataset.


This is one of the important databases for deep learning. Microsoft and Google lab researchers have reportedly contributed to this dataset of handwritten digits. It is basically constructed from NIST that contains binary images of handwritten digits.

Category: Image Processing

Dataset Info: The dataset contains 60,000 examples of the training set and 10,000 examples of the test set. There are four files in this dataset. Here is the link to a paper that implemented this dataset.


LSUN or Large-Scale Scene Understanding is a dataset that is used to detect and speed up the progress for scene understanding that includes scene classification, saliency prediction, room layout estimation, etc.

Category: Image Processing

Dataset Info: This dataset by Princeton University consists of around one million labeled images for each scene and object categories where the test set contains 10,000 images.

4| MS COCO- Common Objects In Context

7| LibriSpeech

This is a large-scale dataset of English speech that is derived from reading audiobooks from the LibriVox project. It contains prepared language-model training data and pre-built language models.

Category: Speech Recognition

Data Info: The dataset contains 1000 hours of speech sampled at 16 kHz that includes recordings of yes-no, Danish pronunciation dictionary, the large-scale corpus of English speech, list of words in Spanish, recordings of African Accented French speech, etc.

8| Open Source Biometric Recognition Data

This dataset provides tools to design and evaluate new biometric algorithms and an interface to incorporate biometric technology into end-user applications.

Category: Biometric Recognition

Dataset Info: This dataset contains open source code for facial recognition, age estimation, and gender estimation.

9| Google AudioSet

This dataset is drawn from YouTube videos and consists of an expanding ontology, the ontology is specified as the hierarchical graph of event categories that covers human and animal sounds, sounds of musical instruments, genres, everyday environmental sounds, etc.

Category: Sound

Dataset info: The dataset consists of 2.1 million annotated videos that include 527 classes and 5.8 thousand hours of audio.

10| Blogger Corpus

This dataset consists of blogs that are gathered from in 2004. Here, each blog is represented as a separate file and each group consists of an equal number of male and female bloggers.

Category: Natural Language Processing

Dataset Info: The dataset consists of collected posts of 19,230 bloggers that incorporates a total of 681,288 posts and over 140 million words.

11| CIFAR-10

This dataset is a labeled subset of 80 million tiny images dataset that was collected by Alex Krizhevsky, Vinod Nair and Geoffrey Hinton.

Category: Image Classification

Dataset Info: This dataset consists of 60,000 32X32 color images in 10 classes with 6000 images per class. The training images and test data consist of 50,000 and 10,000 images respectively.

12| Baidu Apolloscapes
