Top Machine Learning-Based Emotion Recognition Tools

Artificial intelligence (AI) that recognises and understands human emotional signals is referred to as emotion AI.

UCLA is embarking on a three-year study to better understand the impact of “sleep, physical exercise, heart rate, and daily routine” on anxiety and depression symptoms. According to new information on a current study conducted by UCLA and Apple, the researchers are detecting emotions through the use of face recognition, speech patterns, and a variety of other passive behaviour tracking techniques.

The emotion study goes one step further—it makes an inference about your emotional state based on your health data. It is one amongst many increasing numbers of apps that claim to passively evaluate your emotions using what is known as emotion AI or affective computing. The field seeks to comprehend a person’s emotions through the use of numerous data points, including facial expressions and is frequently used for commercial purposes. Recent machine learning-based emotion recognition technologies on an android platform are listed below.

Twiggle

Twiggle is a technology business specialising in developing search solutions for e-commerce sites through machine learning and natural language processing. The Semantic API enables online merchants to increase their existing search capabilities by adding semantic understanding to their existing search engine.

The North Face

The North Face is one of the largest e-commerce shop websites, offering a comprehensive approach to customers looking to purchase items from their sites. The North Face is known to use IBM Watson‘s artificial intelligence technologies to communicate electronically with its users.

Google Now

Google Now is a product associated with Google Feed; it functions as a virtual assistant, doing all users’ important actions and activities. It is equipped with a natural language processor that interprets the user’s voice orders and acts appropriately.

Amazon Alexa

Amazon Alexa is a virtual assistant; it includes functions such as speech and sentiment recognition. Alexa demonstrates a truly unique machine learning concept known as neural networks. As with human neural systems, it imparts the same organic sensations when it is employed. In addition, Alexa demonstrates several aspects of sentiment analysis. Its sentiment analysis algorithm is primarily composed of voice recognition techniques.

Akinator

Akinator is a web-based game and mobile application. It attempts to determine which fictional or real-life “character” would ask a set of 12 questions during playtime. It incorporates artificial intelligence capabilities, which set the questions in such a way that the difficulty level grows in direct proportion to the user’s efforts and experience level. The Akinator is well-known for its exceptionally precise questioning method. This questionnaire generates an extremely precise response.

Chatbot

A chatbot is a text-based platform that incorporates artificial intelligence capabilities. Chatbot refers to conversing with robots. These types of applications are primarily to determine how robots might behave in the presence of humans. It was created with the primary objective of consumer engagement in mind. While some chatbots employ complex natural language processing algorithms, others operate in a far more simple fashion, breaking down all the required keywords in the user’s natural language and creating its own unique patterns as it learns from experience.

Challenges

A group of researchers outlined the difficulties associated with emotion AI. They stated that “Attempts to read out people’s internal states solely from an analysis of their facial movements, without taking into account different contextual factors, are at best insufficient and at worst completely invalid, regardless of how advanced the computer algorithms are.” The researchers urged for a more in-depth examination of how people actually move their features to convey and conceal emotion in a contextual context, as well as how people infer emotions from others’ facial expressions.

Emotion AI is already being used in the recruitment process at big organisations to help candidates understand their personalities. Additionally, this type of technology is being utilised experimentally and commercially in automobiles to detect drowsy drivers, in jail populations to detect stress, and, during the pandemic, in digital classrooms to determine whether online students were suffering from their assignments.
