The Science behind HealthTap

HealthTap is an online service that facilitates virtual conversations between doctors and patients through text, video or audio chat. It provides various services like diagnosis, prescriptions and lab results.

This service utilizes artificial intelligence (AI) to help users narrow down their symptoms list and decide if they need to see a doctor. It also provides potential causes and next steps for care. They assisted with cleaning up affected areas, spraying insecticides and providing relief kits

Machine Learning

Machine learning is a form of artificial intelligence that enables computers to learn from experience without being programmed specifically. It also enables them to adapt and improve as new data becomes available.

Machine learning comes in many forms, but one popular technique is supervised learning. This approach utilizes a model to analyse new information and then forecasts its behaviour in the future.

It can be employed to detect fraudulent activities, classify images and speech, personalize advertising, and maintain equipment maintenance. Furthermore, it has applications in healthcare to detect potential outbreaks and diagnose diseases.

NLP (Natural Language Processing) is an area of AI that helps machines interpret and analyse human language like humans do. It utilizes algorithms and techniques to extract the meaning and structure of words, phrases, and sentences from texts, audio recordings, and other sources.

Natural Language Processing

Natural language processing (NLP) is a branch of artificial intelligence that enables computers to comprehend human speech and writing. This technology has applications across various fields, such as language translation or deciphering social media messages for business use.

NLP technology assists healthcare providers and doctors in sorting through vast amounts of unstructured medical data to guarantee patients receive the highest quality care. It also gives health IT managers insights into social determinants of health and helps advance population health initiatives.

For instance, NLP can sift through an EHR to identify at-risk patients and deliver personalized recommendations for care. It also aids clinicians in improving communication with patients while decreasing their time in the hospital.

Unfortunately, NLP can be challenging to implement due to its inexact nature and ambiguity of natural languages. This could hinder the growth of global NLP in healthcare and life sciences market over the forecast period.

Bayesian Learning

Bayesian learning is a method for drawing stronger conclusions from data by factoring in what you already know about the answer. It’s especially useful when working with limited data and seeking out every last bit of predictive power from it.

This type of learning can also be utilized to quantify uncertainty, which is essential when making decisions based on data. Furthermore, Bayesian methods are robust and less susceptible to being affected by outliers.

Data science and machine learning practitioners often rely on this form of learning, as it helps avoid overfitting and can estimate the uncertainty in a model. Furthermore, sensitivity analysis and comparison between different models are possible with this type of approach.

Pattern Recognition

Pattern recognition is a critical element of machine learning, enabling algorithms to detect regularities within vast datasets. It has applications across many domains such as facial expression recognition, computer vision, speech recognition and medical diagnosis.

Pattern recognition is the process of extracting patterns from data, analysing them and then classifying them according to some established category (class). To do this, some examples whose class labels have already been determined through other means are used as the training set.


Machine learning algorithms use these patterns to train a model that can predict the likelihood of each data point belonging to a certain class or cluster. Furthermore, this model may be employed to estimate the likelihood that an unknown object will exhibit the same pattern.
