2020 08 Best Public DataSets for Machine Learning

Did you know that machine learning is a part of artificial intelligence that enables computers to learn from data without explicit programming using statistical techniques?

Many call this software 2.0.

In recent years, it has evolved from a mere concept into a technology that significantly impacts our daily routines. From email spam filters to voice assistants, movie suggestions, and fraud detection, machine learning plays a vital role in almost every aspect of our lives.

Importance and Role of Datasets in Machine Learning

Data is king. Algorithms are important and require expert knowledge to develop and refine, but they would be useless without data. Datasets are to machine learning what fuel is to a car: they power the entire process.

These datasets, essentially large collections of related information, act as the training field for machine learning algorithms. They allow the algorithms to learn, understand, and make decisions or predictions based on patterns and relationships the algorithm identifies within the data. As such, the quality, diversity, and volume of data you feed into your machine learning model can significantly impact the model’s ability to make accurate predictions.

Whether you’re working on a complex AI project or just dipping your toes into machine learning, this guide will provide valuable insights and resources to help you on your journey. So, let’s dive in and explore the fascinating world of machine learning datasets!


Computer Vision Datasets


Object Detection


What Is Object Detection

Object detection is a cool technique that allows computers to see and understand what’s in an image or a video. It can find and label different kinds of objects (e.g., people, animals, cars, buildings, and more). Object detection is useful for many applications (e.g., security, surveillance, self-driving cars, face recognition, and image captioning).

Object detection works by using machine learning or deep learning models that learn from many examples of images with objects and their labels. These models can then look at a new image and predict where the objects are and what they are called. Some popular object detection models are YOLO, Faster R-CNN, SSD, and RetinaNet.


Object Detection Datasets


Racetrack

Starting with the Racetrack, a dataset composed of 3680 images that could be instrumental in training models for self-driving cars.

With this dataset, you could train a machine learning model to recognize road conditions, obstacles, and other critical factors in autonomous driving. This could contribute significantly to the development and improvement of self-driving car technologies.


Personal Protective Equipment

Next, we have the Personal Protective Equipment (PPE) dataset, offering 8,760 images that could serve as an excellent basis for training models to recognize safety gear in workplace settings.

This dataset could be used to train a model to ensure safety regulations are being followed in workplaces (e.g., construction sites, factories, or hospitals). For instance, a trained model could automatically identify whether workers are wearing the necessary safety gear.


Furniture-6k

This dataset provides ample opportunity to create applications for interior design or e-commerce. You could train a model for object recognition so that users can identify different types of furniture. It could also be used for recommendation systems for interior design applications.


Vehicle Detection YOLOv5

In the transportation and surveillance sector, the Vehicle Detection YOLOv5 dataset could be very useful with its large repository of 7524 images.

With this dataset, you could train models for various surveillance and security applications. This could range from monitoring parking spaces to improving traffic management systems. It could also be beneficial for safety and security measures (e.g., detecting unauthorized vehicles in certain areas).


Fruits

For those working in the agricultural or food industry, the Fruits dataset provides a hefty amount of 7949 images.

This dataset offers an excellent resource for creating agricultural or food industry applications. You could train a model to identify different types of fruits, analyze fruit quality, or even predict harvest yields.


Egyptian Hieroglyphics

Finally, for researchers or enthusiasts in the field of historical linguistics or Egyptology, the Egyptian Hieroglyphics dataset presents a unique opportunity with its collection of 3890 images.

This unique dataset could be used for various academic and research purposes. You could train a model to recognize and translate ancient Egyptian hieroglyphics, potentially opening up new avenues in studying and understanding ancient Egyptian culture and language.

In addition to these specific use cases, having access to these datasets also provides an opportunity to practice and hone your machine learning skills, experiment with different algorithms, and gain insights into how different types of data can impact model performance.


Aquarium

The Aquarium dataset features 638 images from aquarium images.

If you’re trying to detect fish or working in aquaculture or fisheries, this dataset is for you.

The world relies increasingly on fish protein, so you might want to check out this fish dataset and explore the world of underwater computer vision.


Cable Damage

The Cable Damage dataset is a great example of a relevant infrastructure and energy dataset.

This dataset is a good fit for people looking to detect infrastructure damage or people conducting inspections with aerial platforms.

You can train a model to detect cable damage and make periodic inspections faster and more accurate with the cable damage dataset.


Image Classification


What Is Image Classification?

In the field of computer vision, image classification is a fundamental task that has significant implications for various practical applications. However, what precisely does image classification entail, and how does it function within the machine learning framework?

Image classification involves assigning a label to an image from a predetermined set of categories. For instance, the machine learning model aims to accurately determine whether the image is of a cat, dog, or bird in an image classification task with those categories.

In the context of machine learning, the process of image classification typically involves the following steps:

  1. Data Collection: The first step is gathering a dataset of images that have already been labeled with the correct category. This labeled dataset serves as the training data for the machine learning model.
  2. Feature Extraction: Once the data is collected, the next step is identifying the distinguishing features or characteristics within the images. In the early days of machine learning, this was often done manually, with researchers defining features (e.g., edges, corners, or color histograms). Nowadays, with the advent of deep learning and convolutional neural networks, this process can be automated, allowing the model to learn the most relevant features directly from the data.
  3. Model Training: With the labeled data and identified features, the next step is to train a machine learning model. This involves feeding the images and their corresponding labels into an algorithm (e.g., a convolutional neural network), which then learns to map the features of each image to its correct label. This process typically involves adjusting the model’s parameters to minimize the difference between the model’s predictions and the actual labels.
  4. Evaluation and Prediction: After the model has been trained, it can be evaluated on a separate set of images that it has not seen before, known as the test set. This indicates how well the model will perform when classifying new, unseen images. If the model’s performance is satisfactory, it can then be used to classify new images according to the categories it has learned.

From autonomous vehicles that need to identify objects on the road to healthcare applications where images of cells must be classified as benign or malignant, image classification models provide a powerful tool. They transform raw image pixels into meaningful categories, allowing us to build systems that can interpret and understand visual data much as a human would.
