Jordan Jancevski

Greetings, friends! This is Jordan from SnapStack Solutions, and I\’m hanging out with you and chatting about the most important aspects of the IT sector, just like every Friday. This week, as the topic suggests, we are talking about data augmentation. Let’s see what it is and how it works.

The quantity and diversity of data are important factors in the effectiveness of most machine learning models (e.g. deep learning neural network models). Data augmentation is used by businesses to lessen their reliance on training data preparation and to develop more accurate machine learning models faster. Data augmentation is a method of creating data for ML models.

What is data augmentation?

\”Techniques are used to enhance the amount of data by adding slightly changed copies of previously existing data or freshly produced synthetic data from existing data,\” according to Wikipedia. As a result, data augmentation entails the creation of additional, representative data.

What distinguishes it from synthetic data?

One technique to supplement data is to create synthetic data. There are additional methods for data augmentation (e.g., making minor modifications to current data to generate new data).

What is the significance of this now?

Machine learning applications, particularly in the deep learning area, are quickly diversifying and expanding. Techniques for data augmentation might be useful in combating the issues that the artificial intelligence sector confronts.

By creating fresh and varied instances to train datasets, data augmentation can help enhance the performance and results of machine learning models. A machine learning model performs better and is more accurate when the dataset is rich and sufficient.Data collection and labeling may be time-consuming and costly for machine learning models.

Companies can lower these operating expenses by transforming datasets using data augmentation techniques.
Cleaning data is one of the phases in creating a data model, and it is required for high accuracy models. However, if data cleaning lowers representability, the model will be unable to make accurate predictions for real-world inputs.

Machine learning models may be made more robust via data augmentation approaches, which create variances that the model could encounter in the actual world.

How does it work?

For training data, computer vision applications employ typical data augmentation approaches. For picture identification and natural language processing, there are both basic and complex data augmentation approaches.

Making basic changes to visual data is common for data augmentation. In addition, fresh synthetic data is created using generative adversarial networks (GANs). For data augmentation, traditional image processing operations are used, such as padding, re-scaling, zooming, translation, cropping.

In the NLP area, data augmentation is not as prevalent as it is in the computer vision sector. Due to the intricacy of a language, augmenting text data is tough. In NLP, common approaches for data augmentation are:

–       Synonym replacement, word insertion, word swap, and word deletion are all simple Data Augmentation (EDA) processes.

–       Reverse translation

–       Word embeddings with context

What are the advantages of data augmentation?

  • The following are some of the advantages of data augmentation:
  • Improving the accuracy of model prediction
  • Increasing the amount of training data in the models
  • Mitigating data scarcity so that better models may be developed
  • Lowering data overfitting (a statistical mistake in which a function correlates too closely to a small number of data points) and increasing data variability
  • Lowering the cost of data collection and labeling
  • The increasing generalization ability of the models
  • Helping resolve class imbalance issues in classification

What are the difficulties associated with data augmentation?

Companies must develop tools to assess the quality of enhanced datasets. As the usage of data augmentation methods grows, so will the need to analyze the output quality. In order to produce fresh/synthetic data with sophisticated applications, the data augmentation area requires new research and study. For example, employing GANs to generate high-resolution photographs is difficult.

If the original dataset has biases, the data supplemented from it will have biases as well. As a result, determining the best data augmentation approach is critical.

By the way, are you thinking about working with a vendor but aren\’t sure whether to go with leased capacity or a fixed-time project?

Both models are fine; however, the set time/fixed price model will not be as flexible as the other, but it will eliminate the dangers for you. The leased capacity approach will allow you to manage the project, will surely cost less, will provide you more flexibility, and will allow you to own the knowledge gained throughout the project.
Send us a message and will take care of the rest! 😊

What are some instances of data augmentation use cases?

Data augmentation techniques are commonly used in image recognition and natural language processing (NLP) models. Data augmentation is also used in the medical imaging area to perform changes to pictures and provide variety to datasets. The interest in data augmentation in healthcare stems from a number of factors.

Medical photos have a small dataset. Due to patient data privacy restrictions, sharing data is difficult. Only a few patients\’ data can be utilized in the diagnosis of uncommon illnesses as training data.

The following are some examples of studies in this field:

–       Segmentation of brain tumors

–       For medical imaging, differential data augmentation is used.

–       A method for creating tagged medical pictures via automated data augmentation

–       Medical picture segmentation using semi-supervised task-driven data augmentation

Top Seven Machine Learning Applications in 2024

Robots have not yet taken over the world, despite what the sci-fi pop culture of the late 20th century taught us. While all the claims made have not come true, machine learning is now present in almost all spheres of society. In many different industries, computers and AI systems are becoming proficient in a wide range of tasks — the seven machine learning applications we covered in this article are just the tip of the iceberg. 

Top Seven Applications for Machine Learning

Among many applications, machine learning has proven beneficial in: 

Diagnosing Diseases

Finding and diagnosing diseases that are typically difficult to diagnose is one of the main applications of machine learning in healthcare. Typical examples include genetic diseases and a variety of cancers that are difficult to detect in their early stages.

For instance, the now-defunct IBM Watson Genomics project offered a very good example of how cognitive computing and genome-based tumor sequencing can result in a much quicker diagnosis. Similar to this, Berg, a well-known biopharmaceutical company, has already used machine learning to create treatments for a variety of conditions, including oncology.

The PreDicT program from P1Vital, which stands for Predicting Response to Depression Treatment, is another excellent illustration of machine learning applications in the healthcare industry.

Image Recognition

Image recognition is a common practice. Have you noticed the automatic scene and facial recognition feature in the gallery app on your smartphone? Machine learning was used to accomplish that. The same is true for social media functions like auto-friend tagging. 

Consider Facebook’s DeepFace technology, which makes recommendations for friends to be tagged in images. Modern secret surveillance systems used by some governments around the world rely on machine learning-assisted image recognition as well.

Machine learning-based image recognition has uses in the healthcare industry as well. Missing even a small detail during many treatment procedures could have disastrous effects. Image detection can be used in scans and X-ray images to find even the smallest differences between two points. This method is especially beneficial for precisely tracking the development of a virus infection or the spread of a tumor.

Autonomous Vehicles

Regardless of the circumstance, AI is anticipated to outperform a human driver in autonomous vehicles. Machine learning algorithms are useful in this situation as they enable autonomous vehicles to make decisions instantly.

The onboard computer of self-driving cars like the Tesla Model S or Ford F-150 uses machine learning to process data input from a variety of sensors. This is to guarantee that the ADAS can interpret the environment around the vehicle safely and accurately. This data stream is used by the system to regulate the direction and speed of the vehicle. The data is also processed for other crucial tasks like object detection and tracking, perception, and forecasting.

Detecting Online Fraud

Machine learning is becoming more and more effective at protecting our online transactions and spotting fraud. It works particularly well at spotting fraudulent activity involving the use of phishing, fake accounts, and IDs.

To suggest risk rules, machine learning algorithms are trained on historical data for fraud detection. These rules can be used to prevent users from taking specific actions that have been flagged as suspicious, such as unauthorized logins, potential identity theft, fraudulent transactions, and so forth.

Data scientists typically provide a massive amount of records of previous fraud and forgeries to the machine learning model. To minimize false positives, they also flag non-fraud cases. The rule suggestions are typically more accurate with more data to work with.

Product Recommendations

Prime examples of machine learning applications in business are product recommendations on e-commerce sites and entertainment platforms. The "recommender systems" that produce and distribute these recommendations use machine learning algorithms to divide up the customer base according to user information and behavioral trends. The browsing history, likes, shares, and other user actions are used to gather user information and behavioral patterns.

Intelligent Virtual Assistant (IVA)

IVAs are computer-based systems that use machine learning to comprehend natural language, or human language, and respond appropriately. Each question is presented with a multiple-choice selection of responses by these clever AI assistants. They can decipher user intent from the free text as well.

IVAs, also known as Virtual Customer Assistants, are being used more and more in automated customer support. This enables users to express to the machine even very specific concerns in the same way they would to a human.

IVAs should be understood to be distinct from chatbots. They are much more intelligent and able to comprehend spoken language. In contrast, the majority of chatbots engage users by providing straightforward yes/no response options.

Now that no-code products are more prevalent, you can create IVAs in as little as 15 minutes. 

Trading

The use of machine learning in trading stocks and cryptocurrencies is also expanding. The internal calculations and analyses are performed by sophisticated machine learning algorithms. The data produced aids traders in making wise choices.

More specifically, machine learning is useful for identifying signals in alternative and financial data. The development and backtesting of systematic strategies can then be done using these signals.

What Does the Future Hold for Machine Learning Applications?

Applications of machine learning are becoming prevalent in many facets of our society. Much more than what we talked about above, sentiment analysis, data collection and classification in cosmology, marine life studies, engineering, military intelligence, and even digital art are some additional common applications. 

Every day, as artificial intelligence expands, more technological advancements become possible. Given the importance and relevance of this technology, it makes sense for you to educate yourself about it — and make good use of ML for your businesses.
