Quality AI Training Dataset For AI Models

Machine learning algorithms are able to learn from data. Machine Learning algorithms learn from data. They discover relationships, understand, make decisions and assess their confidence based on the training data. The better the training data, the better the model performs.

Algorithms learn data. Algorithms learn from data. They discover relationships, understand, make decisions and assess their confidence based on the training data that they are given. The better the training data, the better the model performs.

The quality and quantity you provide for your training data is just as important as the algorithm itself.

Even though you have a lot of data that is well-structured, it may not be labeled in the right way to make your model work. Autonomous vehicles need images of the road. They also need labels that indicate where each pedestrian, car, and street sign are located. Sentiment analysis projects need labels to help an algorithm recognize when someone is using slang and sarcasm. Chatbots require entity extraction and precise syntactic analysis. This is not enough to analyze raw language.

This means that the data you wish to use to train must be enriched or labeled. You might also need more data to power your algorithms. There is a chance that the data you have stored may not be ready for use in machine learning algorithms.

The Importance of Training Data

The key to designing the solution is knowing the data. This helps to accurately estimate the cost, time and skills needed for the project.

The resultant application won't be able to make accurate or reliable predictions if the data used to train ML model will be inaccurate.

What is the right amount of data?

  • It depends.
  • The required data depends on many factors.
  • The complexity of the Machine Learning project that you are undertaking
  • The training method you choose will depend on the project's complexity and budget.
  • Specific project labeling and annotation requirements.
  • To train an AI-based project correctly, you need to have the right dynamics and a variety of data.
  • The project's data quality requirements.

Make educated guesses

1.Rule of 10

Rule of thumb: To develop an efficient AI model, you will need ten times as many AI Training Dataset as each model parameter. These are also known degrees of freedom. The '10 times' rules are intended to reduce variability and increase diversity. This rule of thumb will help you get started with your project by giving you an idea of the required number of datasets.

2.Deep Learning

If more data is available to the system, deep learning can help create high-quality models. Deep learning algorithms can be made to work with humans by having at least 5000 images labeled per category. For extremely complex models to be developed, you will need at least 10 million labels.

3.Computer Vision

Deep learning is used to classify images. A set of 1000 images is considered fair if there are at least 1000 images.

4.Curves to Learn

To show the relationship between data quantity and machine learning algorithm performance, learning curves can be used. It is possible to see how the data size affects the project's outcome by having the model skill on Y-axis as well as the training dataset on X-axis.

What to do if there are more datasets you need

1.Open Dataset

Open data sets are often considered to be a good source of free data. Open datasets may be a good source of free data, but they are not always what a project requires. Data can be obtained from many sources including government sources, EU Open Data Portals, Google Public Data Explorers and others. Open data can be used for complex projects, but there are some drawbacks.

You run the risk of training your model and testing it on inaccurate or missing data. Data collection methods are not generally known which can impact the project's success. Open data sources have significant disadvantages in privacy, consent and identity theft.

2.Augmented Dataset

Data augmentation is a technique that allows you to use limited amounts of training data to fulfill your project needs. You can repurpose the data to meet the needs for the model.

Data samples will go through various transformations to make them richer, more varied and more dynamic. An example of data augmentation is when working with images. A picture can be enhanced in many ways. It can be resized, mirrored or turned into different angles. Color settings can also be altered.

3.Synthetic Data

Synthetic data generators can be used when there is not enough data. Synthetic data is useful for transfer learning because the model can be trained first on synthetic data, then on real-world data. An AI-based self driving vehicle can be trained to recognize and analyze objects within computer vision games.

When there is no real-life data, synthetic data can be useful. It can also be used to protect privacy and sensitive data.

4.Collect Custom Data

When other methods fail to produce the desired results, custom data collection may be the best way to generate datasets. You can create high-quality datasets using web scraping tools and sensors, cameras, or other tools. If you require custom datasets to enhance your models' performance, purchasing them might be the best option. Many third-party service providers are available to offer their expertise.

High-performing AI solutions require that the models are trained using reliable, high quality datasets. It is difficult to find rich, detailed data that can positively affect outcomes. Partnering with reliable data providers can help you build an AI model that is powerful and has a solid data foundation.

My work with companies to build data science roadmaps and hire plans has allowed me to see across many industries. Although I cannot name names, I will summarize from around 20 companies. These include two small startups and four multinationals employing more than 100,000 people. As a linguist, only a handful of these are about images and music. Most are about classifying text to aid in search or routing. You might assume that many of these are sentiment projects. However, only five of them actually are.

  • Training budgets increasing: More organizations are using machine learning/AI techniques in more places which means that there is more training data. The amount of training data for companies with less than 5,000 employees has more than doubled between 2015 and 2016. Training data rose 5 times for companies with more than 5,000 employees.
  • Changing your business requires new training data: A machine learning system can only learn from what it has been trained on. If you plan to launch new products/services, or enter new markets, it's important that you have enough training data available in the next two months. It's great if you can find a way to obtain relevant data before your launch.
  • You can plan for 63,000 training materials per month:  Remember the caveats I gave you when I first started? This is the most important. Five companies that I report on receive more than 121,000 training materials per month. The lower limit is closer to 14,000 items per monthly.
  • Make a commitment to have your in-house experts review categories every quarter:  Businesses change and you want to ensure that everyone agrees on the categories that are important and that they are consistent. It's a great opportunity to show them both examples and the most difficult items.

How to fly

Machine learning projects that are brand new usually produce about 131,000 items of training within the first quarter. (Top quartile: 309,000; bottom quartile, 12,000). These are just the numbers, but what's more important is how you achieve meaningful results.

These are the three important things to remember:

  • Pilots should be iterative - you almost certainly won’t get it right the first time. You should launch a subset of pilots and then analyze the results. It's likely that you will need to modify the instructions or other parts in your experimental design. This is worth planning for several iterations.
  • Make sure your data matches the problem. If there is a business problem, it is crucial to ensure that the data is correct. One company wanted to use YouTube comments as sales leads for high-tech equipment. Although there are many interesting ways to locate needles in haystacks, there must still be needles to be found.
  • Schedule an annotation lunch as soon as possible. Once you have a clear understanding of the project, data and categories, you can book a room with in-house experts to help you annotate the data. You can have three people judge each item so that you can share your inter-annotator agreement. How can other people or machines do the task if your experts are unable to do it?

Your in-house experts such as GTS will only require a few "annotation hours". You may need to do more rounds if you don't agree with your experts on how to categorize the data.
