    Types of Machine Learning Algorithms for iOS and Android Apps

    There are different approaches to defining ML algorithm types. We will categorize them according to the degree of human control and intervention.


    types of machine learning algorithms


    • Supervised learning

    This type of ML learning uses labeled and marked datasets that consist of inputs and expected results. If AI processes input data but offers different results from what you expected, it needs to correct its calculations. This process will continue until the AI stops producing incorrect results.


    Supervised learning is commonly used in applications where historical data predicts likely future events—for example, in healthcare applications, where the task is to understand if the patient is ill with a particular disease, knowing all the medical indicators. 


    • Unsupervised learning

    In this case, AI uses information that is not classified, labeled, or marked. Unsupervised learning allows the AI to perform logical data classification independently.


    Unsupervised learning can be used in e-commerce apps that have recommendation systems. For example, in a mobile version of an online store, AI can offer customers products that are more likely to interest them, based on an analysis of previous purchases.


    • Semi-supervised learning

    Semi-supervised learning algorithms are between supervised and unsupervised learning. In this case, AI needs to work with very few labeled examples and many unlabeled ones. However, the task is to use all the available data effectively. 


    This type of machine learning can be used in apps that process image, text, or audio data, as these types of data cannot be easily addressed using standard supervised learning methods.


    • Reinforcement learning 

    In this case, there are no correct answers, and the algorithm tries to find the optimal strategy. AI has a set of actions, parameters, and final values. Having defined the rules, the algorithm explores different options and possibilities, tracking and evaluating results. Based on the feedback, it determines which option is the best. It’s a sort of cut-and-try approach where the machine learns from past experiences and changes its methods to achieve the best possible result.


    For example, this type of ML algorithm can be used in robotics, where a robot’s navigation system learns to avoid obstacles. It can also be used in logistics, scheduling, teaching the machine to play logic games, etc.


    How Mobile Developers Use Machine Learning to Build Apps

    Machine learning helps understand user behavior, then uses this understanding to create customized solutions. Mobile app developers integrate ML into their products to create personalized apps for each person. Using and studying the clients’ daily activities, the application analyzes their behavior and learns to use this information. Thus, machine learning allows developers to make their mobile apps more responsive.

    using machine learning in apps

    In addition, machine learning helps in performing predictive analytics. It provides quantitative data after analyzing large amounts of information. In some cases, machine learning helps filter out spam and potentially unsafe sites, positively impacting the application user’s security. And of course, some machine learning-based applications can recognize text and understand it. 


    Let’s dig deeper into different machine learning techniques that can be applied by mobile app developers.

    1. Data Mining

    Data mining technology is intelligent data processing with mathematical statistics and the theory of databases. Data mining helps solve classification, clustering, description reduction, association, forecasting, and analyzing the deviation of large amounts of data.


    One of the best examples of using ML in data mining is a travel app. With this technique, a machine learning algorithm collects user data and classifies it according to different criteria (gender, age, social media profiles, locations visited, etc.). Then you can use this information to update schedules, change tours, add new directions. Thus, it allows you to turn your app into a custom solution. 

    2. Tracking

    It’s difficult to imagine a modern person that doesn’t track something. We track our heart rate and water balance with ML-based trackers. Moreover, we track our financial and banking activities using ML apps. In financial tracking, the algorithm uses the users’ credit and transaction data and offers them the best deals.


    And the use of ML in finance goes beyond simple tracking. We recommend you check these 5 Uses of Machine Learning in the Finance and Banking Industry to see how you can use ML in the FinTech field.

    3. Analysis

    Analyzing data is critical for electronic and mobile commerce because it helps companies better meet their customers’ needs and wants. ML analysis technique helps to analyze the behavior of users and their preferences. Based on this data, your application can recommend goods or offer customers something similar.

    4. Search

    ML search techniques help improve users’ search results. The application learns to show the most relevant results based on the search request, screen scrolling, and clicks. The program understands the user’s past behavior and history and suggests the most suitable products and search results.

    5. Monitoring and security

    Machine learning algorithms enable mobile app developers and users to monitor network activity and set alarms that will be triggered in case of fraudulent activity. Moreover, ML allows using voice recognition, biometric, and audiovisual data for authentication to secure users’ data.
