What is the Importance of Data Annotation For ML Modals training?

 

INTRODUCTION

Machine Learning and Artificial Intelligence will be around humans for a long time in the future. Almost every task in today’s world can be automated and made easy with the help of ML and AI. In recent years AI and ML have revolutionized our lives in a positive manner and have created a smart and easy living environment for humans.

Right from self-driving cars, to Alexa, and smartwatches, everything is based on the application of AI and ML. You know the beauty of these two magical technologies but do you know AI and ML depend on well-annotated data? For the testing of any ML model data, annotators need to feed their ML algorithms with accurately labeled data.

Let’s first have a look at the definition of Data Annotation.

What is Data Annotation in Al or ML?

It is a technique of tagging labels in contents available in a range of formats. Data annotation plays an important role in making sure that AI Dataset or ML projects are scalable. Training an ML model requires the model to understand and detect all the objects of interest in algorithm inputs for accurate outputs.

Data annotation is the workhorse behind AI and ML algorithms and it creates a highly accurate ground truth that directly impacts algorithmic performance. Annotated data is critical for the accurate understanding and detection of input data by ML and AI models.

Here are some of the data annotation techniques used in various ML projects.

Four Major Types Of Data Annotation And Labelling

Data annotation for machine learning projects is a broad practice, but every type of data has a labeling process joined with it. Here are the top commonly used types of data annotation:

Text Annotation For NLP

Text annotation for NPL is carried out to create the communication mechanism among humans communicating in their local dialects of languages. In this case, the text annotation is done using virtual assistance devices and AI chatbots to give answers to various questions put across by the individuals. Although different text annotation types are existing, a common feature is a metadata that is added to create recognizable keywords for machines to make critical decisions.

Video Annotation For High-Quality Visualized Training

Video annotation is done to make machines recognize moving objects through computer vision. Also, precision is the key to video annotation, such as annotating frame-by-frame objects, and different objects are also annotated to estimate their movements.

Image Annotation For Recognizable Objects

It is done by keeping one goal of making objects of interest detectable and recognizable to visual perception-based ML models. With the image annotation, the object is annotated and tagged with different elements that make it easy for AI-enabled machines to observe the ranging projects.

NLP Annotation For Speech Recognition

In the NLP annotation, the language is focused and the tagging is used to unravel the deepest insights from the nature of the language. The NLP annotation process consists of parts of speech (POS) Tagging, Semantic Annotation, Phonetic annotation, Discourse Annotation, etc.

These are some of the data annotation techniques used in different ML models. Let’s have a look at the benefits of data annotation in ML.

Benefits Of Data Annotation In ML

There are multiple benefits of using these data annotations that you can use to train your ML model. Here are some of the benefits of data annotation services

for ML and AI projects:

• Supervised Learning: With supervised learning, ML projects are receiving accurate training to make the correct prediction and estimation.
• ML Automated Systems: ML automated systems can give you various stellar experiences for the end-users. For example, digital assistance devices and chatbots respond to users’ queries.
• Web Search Engines: Web search engines are using ML technology like Google in improving the accuracy of their results based on the history of search behavior.
• Improved Precision Of AI and ML models: A computer vision model operates with different levels of precision over an image where several objects are labeled accurately. So, it’s better for annotation to have a higher precision of the model.
• Fast Track Model Training: Data annotation companies study the footage of a traffic signal to identify and label the automobiles by their category, color, model name, and direction of travel. Machine learning projects have the capability to reduce 54% TAT for a data analysis service provider.
• Streamlined end-user experience: Users can get a seamless experience of the AI systems with well-annotated data. An efficacious intelligent product addresses the problems and doubts of users by just providing relevant assistance.

Future Of Data Annotation With Technological Advancement

The usage of data annotation is going to increase dramatically in the future due to the advancement in ML and AI projects. Altogether, a massive positive forecast for the data annotation market can be attributed to the following future technological trends in space.

Smart labeling tools will dominate the future of the AI and ML space. These tools along with the predictive analytics the data annotation capabilities will be fully automatic. Also, they detect labels without any manual intervention.

The reposting framework is an embedded component of data annotation processes. The Operational intelligence will offer an understanding of how annotation complexities are being handled.

With a need to sustain accuracy levels, automation plus strong quality control is essential to separate the high-volume data. It is the key character of next-gen data annotation, not sheer labeling but gauged and quality labeling.

Summary

Great data annotation is only possible with the combination of human intelligence. Also, it is using smart tools to create high-quality training data sets for machine learning. The MIT technology review report rightly says that rightly annotated data has been the biggest challenge to employing AI.

Businesses should build strong data annotation capabilities to support ML and AI model building and prevent it from failing. We, humans, are notch above the computers since we can better deal with ambiguity, and decipher the intent. Accurately annotated data determines whether you create a high-performing AI/ML model as a solution to a complex business challenge. GTS also provide text dataset, voice data collection, video data collection, image data collection and OCR data collection services.
