The YouTube Dataset

The YouTube Dataset

This is a more advanced dataset. Are you ready to tackle videos and audios? This is the right dataset for you. This dataset contains human-verified annotation segments that aid in video annotation. Additionally, this dataset plays a part in localizing video identity. The YouTube dataset contains uniformly sampled but high-quality videos containing labels and annotations.

The YouTube-8M project’s main aim was to address barriers in computation and eliminate challenges on storage. As a result, this would assist expedite the extensive research on the comprehensive scaled understanding of video. The team carrying out the study first published its research findings, terming it a large-scale perspective on benchmarking video classification.

The initial 8milion dataset for video is deprecated and has been replaced with videos about 6.1M with features inclusive of 3862 class, 2.6B audio-visual features, and 3.0 video as well as labels.

The new dataset also has segmented videos with 1000 classes, about 230K segment labels verified by humans, and five video segments. The core concentration on the latest research prioritizes video segments. Apart from using the video dataset, its focus is a narrowed 1000 classes for the selected videos’ specific segments.

Compressed protobuf is at the core of storing video files, stored as objects before grouping to TFRecords. They also use file structures of the TensorFlow version.

Two feature types broadly fall into either the video-level or the frame-level. The video-level features mostly consist of the RGB aspects and audio, whose per video averages less than target RGB features and audio per frame.

Also, note that the dataset has visual and audio features pre-extracted from all the seconds of the videos amounting to about 3.2B in a total of feature vectors. If you would like to establish a private feature extractor, you can extract specific features for your consumption from the GitHub repository of MediaPipe. The latter approach is highly recommended if you seek to adventure on features that have not yet been used. Or maybe you want to use it on a novel dataset.

There are various locations where you can get the specific data you intend to use. However, this is dependent on the listing of your desired group.

For instance, training data at the frame-level can be accessed from the YouTube-8M site or downloaded using the following script.

curl data.yt8m.org/download.py | partition=2/frame/train mirror=us python

The other alternative is using Google Cloud Storage, whose link is shown below.

gs://us.data.yt8m.org/2/frame/train

On the other hand, training data at the video-level can also be accessed on the YouTube-8M site or engaging the following script to ensure you get the dataset from the removed servers to your local machine as follows:

curl data.yt8m.org/download.py | partition=2/frame/train mirror=us python

It is also available on Google Cloud Storage, and the link for easy accessibility is as follows:

gs://us.data.yt8m.org/2/video/train

On data validation and testing, you have the option to either connect it to Google Cloud Storage or using a Python Script to aid with the downloading.

Case 1: Linking to Google Cloud Storage

validate files at gs://us.data.yt8m.org/3/frame/validate
test files at gs://us.data.yt8m.org/3/frame/test

Case 2: Using Python script to download

curl data.yt8m.org/download.py | partition=3/frame/validate mirror=us python
curl data.yt8m.org/download.py | partition=3/frame/test mirror=us python

Note that while using the Python script, you can select either validate or training data.

More advanced machine language enthusiasts will enjoy using this dataset. If you are a newbie, please keep off from this dataset as it entails natural language processing, which is complicated if you are new to the system.

This dataset includes reviews, votes, ratings, product meta information, price, brand, image features, and links. The dataset is complicated since it spans more than 20 years of reviews. The amazon reviews dataset contains more than 45 million reviews depicting how vast it is.

The Amazon customer reviews dataset spans over one hundred and thirty million records and is available for use by researchers at the following link:

s3://amazon-reviews-pds/tsv/
s3://amazon-reviews-pds/parquet/

The files’ format is TSV, which is a text format, and Parquet, which is a columnar optimized binary format.

Further, the data is located in the East Region of AWS US. It is worth noting that a single line represents every single review in the dataset mentioned above. The data does not have escape characters or quotes but is delimited by tabs. For your knowledge, the data is available in both French and English.

You have two options to manipulate the reviews dataset. The first option involves downloading the entire collection of data to your local machine. Amazon has a command cp essential in downloading the deliberations over the AWS command-line interface, as shown below.

aws s3 cp s3://amazon-reviews-pds/tsv/amazon_reviews_us_Camera_v1_00.tsv.gz .

The second option involves manipulating the data directly from the CLI. For example, you can list the files using the following command line.

aws s3 ls s3://amazon-reviews-pds/tsv/

Besides the rich span within which this data was collected, it also sparks interest in studies about customers’ overall evolution. Besides, there is the potential expression of the different ways and approaches that customers express their experiences.

The reviews on products are particularly essential in understanding the user’s perception of the different products and variations in customer preference across the globe. It also depicts the consumer preference based on regions, countries, and language diversity.

There is also a separate collection of reviews that violates Amazon policies and contrasts thoughts with biasness or those for promotional purposes. However, this data is only available upon request and is distributed independently.

Hence machine language experts will find this dataset more useful in understanding data science more deeply.

The ImageNet Dataset

The ImageNet Dataset

This is among the best learning datasets. It is mainly focused on computer vision. It contains more than 1000 categories with images on them.

This dataset is known for running the most significant machine learning challenges, the (ILSVRC) ImageNet’s Large Scale Visual Recognition Challenge that produced many modern neural networks. At the moment, ImageNet has more than 500 images per individual node.

The dataset released for the public has sets of images whose annotation has been manually set and fall into either test images or training images. Also, ILSVRC annotation categories include object level annotation and image-level annotation. In the latter annotation, the aim is to determine the absence or presence of an object class in the image’s binary label.

On the other hand, annotation at the object-level involves a class label around an instance of an object in the image and a bounding box that is relatively tight.

To your knowledge, the copyright for the images is not owned by the ImageNet project, and thus, only URLs and thumbnails of the images are provided.
