The Performance Of Your Facial Recognition Model Depends On The Data You Feed It -Big Data

The Performance Of Your Facial Recognition Model Depends On The Data You Feed It -Big Data Analytics News

We’ve seen them in films, we’ve read about them in books and we’ve experienced them in real life. As sci-fi as it may seem, We have to face the facts — facial recognition is here to stay. The tech is evolving at a dynamic rate and with the diverse use cases that are popping up across industries, the wide range of developments of facial recognition simply appear to be inevitable and infinite.

Apart from helping us unlock our phones, facial recognition is used in criminal identification, optimize public safety and security, make banking and finance more secure, prevent shoplifting, and more.

The adoption of facial recognition across the world is so extensive that the global value is expected to be around $7bn by the year 2024. Not just that, in the next couple of years, close to 97% airports will be incorporating recognition technology.

However, deploying facial recognition technology in a business, venture or initiative is not an easy task. Technically, there are tons of challenges involved in terms of developing the right artificial intelligence models, building precise machine learning and deep learning algorithms, defining data sourcing or data collection strategies, and more.

For a facial recognition model to identify one particular face or emotion, it has to go through millions of datasets. This is because for it to learn what a smile is, it also has to learn what a smile isn’t. It has to go through millions of datasets on emotions like anger, resentment, regret, contentment, and more to differentiate a simple smile from the rest.

And this brings us to the topic of the importance of the right dataset for your facial recognition model.

What role does the quality of a dataset play in the efficiency of a facial recognition model?

Is data more important than algorithms?

Well, let’s find out.

The Significance of Right Data Sets For Facial Recognition Performance

One of the major hindrances to the efficient functioning of machine learning algorithms is the feeding of poor-quality data sets. The unavailability of quality data will plague the decision-making and analytical skills of the model you are trying to build, completely compromising its purpose. All your intentions with predictive and prescriptive analytics will be skewed with your model spewing incorrect and haphazard results.

To avoid these, it is on us to feed the modules with the right datasets and by right datasets, we mean the data needs to be:

  • generated or collected from correct, appropriate and relevant sources
  • adequately labeled or annotated
  • de-duped
  • and unbiased and devoid of assumptions

A facial recognition model is only as effective as the data it processes and if the data is improper or inadequate, the processing model has no true purpose or acceptable outcome. That’s exactly why data collection and annotation is crucial in building recognition models.

How Data Annotation Optimizes Facial Recognition Models

Some may think that data in facial recognition is just a repository of images of faces, however, these chunks of images cannot be directly fed to a facial recognition model. If you do, the model wouldn’t know what the image is, what it means or what to do with it. To help the model better understand, we annotate or label the data by assigning diverse attributes and parameters.

This could be as simple as drawing bounding boxes to developing semantic segmentation techniques, where every single pixel of the image is given a meaning. This helps the model differentiate, for instance, an eye from an eyebrow, a nose from an ear, and more.

The more such data the model is fed, the better it becomes at recognizing the nuances of the human face. In complex cases, data annotation can also be used to define the emotions, moods, and behaviours of people for the models to understand.

Despite sounding simple, the next challenge in the process is the availability of massive datasets to train the models. To build a facial recognition system, millions and millions of images have to be sourced and fed. And that’s where expert data annotators and AI ventures such as Shaip come in. With their repository of relevant images and data sourcing strategies, they can help train your models with the most appropriate data.

Facial Recognition: Use Case

When the model is trained with the right dataset, it can be used to perform diverse actions. To give you an idea of the most effective real-world applications of facial recognition, here’s a quick list.

Facial recognition is used in –

  • the detection of missing persons/children
  • prevent shoplifters from indulging in retail crimes
  • rolling out smarter and more personalized advertisements
  • helping the blind community communicate better with haptic feedback and notifications
  • optimizing law enforcement with real-time details on criminals and individuals in the vicinity
  • social media channels for tagging purposes
  • diagnosing diseases by detecting changes in the face that can go unnoticed to the naked eye
  • making schools airtight from threats and attacks
  • tracking and monitoring classroom attendance
  • preventing cheating and fraudulent transactions in casinos

Wrapping Up

Facial recognition has more use cases than we can imagine and with our implementations today, we are only scratching the surface. As the use cases become more advanced and requirements become more complex, comprehensive data annotation techniques would be needed to train highly sophisticated algorithms and keep pushing the boundaries of facial recognition innovation.

Are you prepared for the future?

How AI Will Power the Next Wave of Healthcare Innovation

How AI Will Power the Next Wave of Healthcare Innovation?

There’s no doubt that data is poised to transform healthcare like it has so many other sectors, but it’ll need a helping hand. Today, healthcare providers are collecting exabytes of patient data from hospitals, clinics, imaging and pathology labs, and more. This data contains a wealth of insight into human health, but its lack of structure and sheer volume means it’s well beyond the limits of the human ability to decipher it.

Fortunately, sophisticated AI and machine learning solutions can carry the torch of innovation.

In healthcare, the value of machine learning is its capacity for processing massive data sets that are far beyond the scope of human ability. Raw, unstructured data goes in and clinical insights come out, helping physicians plan and provide better care at a lower cost. While the sky is the limit as far as the benefits of machine learning, constructing these complex algorithms takes time. In the next five to 10 years, we expect to see medical professionals reaping the dividends of healthcare-based innovation in these areas:

Big Data Jobs

Advanced image analysis: Medical professionals are highly trained, and some of their work reflects their tremendous value add. However, there’s still a need for professionals to spend time on repetitive tasks such as image analysis. In radiology, for example, doctors spend time looking at images from CT scans, MRIs, ultrasounds, PET scans, mammography, and more. AI-assisted imaging solutions are using the technology’s advanced pattern-recognition capabilities to highlight image features, identify early predictors of cancer, prioritize cases, and cut down on the volume of labor required to perform accurate diagnoses. As AI processes more and more data sets, it’s inevitable that the technology will eclipse the ability of human doctors to spot the signs of disease as early as possible.

  1. Disease detection: Due to its high cost, healthcare imaging generally takes place only to confirm a diagnosis. It’s an effective solution, but one that AI promises to upend and replace. By conducting an in-depth analysis of huge amounts of historical data, AI can predict the possibility of sickness or disease at incredibly early stages. For example, by looking at an entire patient population that closely matches the demographic of a specific individual in addition to the medical history of relatives, AI could conclude that a patient is very likely to develop a malady such as heart disease years before a doctor could ever accurately make a diagnosis.
  2. Drug discovery: We’ve all seen firsthand how important it is to design and produce effective drugs and vaccines to combat a newly discovered disease. Historically, this process has taken massive investments of time and money, with development timelines extending out to more than a decade in some cases. The ability of AI to cross-reference drugs that are known to be safe and effective and replicate parts of their formulas to suggest new iterations could be groundbreaking, potentially saving countless lives and helping to prevent the next global pandemic.

3. Digital consultation: The pandemic undoubtedly spurred innovation in the telehealth space, but there’s still a long way to go to make virtual visits as effective as a physical visit to the doctor’s office. AI can help close that gap in numerous ways. Machine learning and natural language processing (NLP), for example, will help facilitate symptom collection using just a patient’s voice. Combined with an analysis of the patient’s electronic health record, AI can highlight probable health concerns for doctors to review. By processing information ahead of time, AI increases the volume of patients that doctors can handle, improves the efficacy of virtual visits, and even minimizes the risk of infection from physical interactions as a result.

At Shaip, our goal is to usher in the exciting future of healthcare innovation by supporting firms in their AI initiatives. We help organizations build and train AI and NLP models by licensing the use of more than 10 million medical data sets consisting of images, electronic health record data, and even physician speech.
