Advantages of Machine Learning 

With an overview of machine learning and its applications being provided, here we have elaborated upon some of the most advantageous aspects of this technology that make it a popular domain of AI being put to use to enhance services. 

 

1) Efficient Identification of Trends & Data Insights 

The first and foremost advantage or benefit of utilising machine learning technologies is the efficiency with which it is able to spot data patterns and trends, many of which would be difficult to spot by humans. Being equipped to easily manage and interpret vast datasets, ML models can make coherent sense out of data to draw insights useful from a business enterprise perspective as well as for increasing the efficiency of predictions made by the model. 

2 ) Seamless Process Automation 

As is the case with a large number of technological advancements, ML also presents the benefit of seamlessly automating a large proportion of tasks in organisations. It helps in the automation of data analysis, AI model training and also the performance of repetitive backend tasks. While supervised and semi-supervised machine learning require some degree of human involvement in dataset feeding and training, unsupervised and reinforcement learning technologies are autonomous, helping the model to develop increasingly accurate predictions with time by autonomously learning and strengthening the ML model.

3) Customised Services to Users

One of the primary advantages of integrating machine learning technologies in softwares and machine is the high degree of customisation and personalisation they are able to provide to customers and users of those softwares. The primary mechanism of operation of an ML model revolves around being able to make accurate predictions based on datasets and insights. This technology is used in customer services as well as to provide personalised suggestions to users. For example, the customised playlists suggested and created by musical streaming platforms rely on huge datasets consisting of histories of users’ musical preferences and usage on the application to draw insights and provide suggestions based on those insights. This degree of customisation has been made possible to apply due to the automation and predictive power of machine learning technologies. 

4) Applications in Fraud Detection and Cybersecurity 

Owing to the efficient capability of identifying trends and patterns in data, ML models find a crucial application in the domain of fraud detection and cybersecurity, especially in sectors of cyber-vigilance and finance. In the financial sectors, such ML models are deployed to track the patterns of financial transactions and exchanges as well as detect any unusual transactions and behaviours which may indicate potential cyber fraud. 

5) Role in Predictive Analytics 

One of the major functions and purpose of creation of efficient machine learning models and algorithms is for the model to feed on vast amounts of data to come up with accurate predictions. These predictions could pertain to predictive analytics related to effective solutions, potential future trends, demands for products and services, values of services/stocks etc. These predictive analytics make it highly instrumental for business enterprises for guiding business decisions, strategies as well as using ML technologies for customer needs. 

6) It Learns Autonomously 

An aspect of ML algorithms and models related to its process automation is its ability to train itself and autonomously learn. As the name of the technology suggests, it is used to train and make machines learn smart behaviour on the basis of insights drawn from vast data. Unsupervised and reinforcement learning require minimal human intervention for data inputs and enable the ML model to learn autonomously to function well. In the case of semi-supervised and supervised learning as well, ML models continue to learn autonomously post the provision of labelled data, making its predictions increasingly accurate over time. 

7) Well-equipped to Handle Diverse Data 

Another major benefit contributing to the widespread integration of AI and ML technologies is such models’ ability to handle a wide variety of datasets, whether it be small data with limited data points or big data with thousands of data points, whether it is labelled or unlabelled data, numerical or textual and categorical data etc. ML technologies are designed to cater such various types of data and efficiently produce insights relevant for interpretation of those datasets. 

8) Widespread Applications 

Lastly, a major advantage of ML technologies are their widespread applications ranging from crucial domains like cyber fraud detection, security and vigilance in financial and BFSI industries, self-driving cars, stocks price prediction to everyday usage such as customer services, personalised suggestions for video streaming, music and so on. 

Disadvantages of Machine Learning

As has been elaborated above, machine learning as a field surely serves functions that make it highly appealing for applications in diverse industries. But it is of utmost importance to be aware of the disadvantages, limitations and potential threats that machine learning can have before such a widespread deployment of such technologies. 

Enlisted below are a few of the pertinent concerns surrounding machine learning about its limitations and disadvantages. 

1) Difficulties in Data Acquisition & Dependence on Data Quality

One of the primary problems in the very development of machine learning models is the requirement of vast datasets for the model to train from. For instance, for effective training of an ML model, a large dataset consisting of thousands of data points are required. In addition to the size of the dataset, the training of the ML model is dependent on the quality of the data as well, as it contributes to the accuracy and unbiased nature of the interpretations. The maintenance of the quality of data requires regular data cleansing, data updation, ensuring that the data is unbiased, data monitoring and so on, all of which requires significant time and effort. 

 2) Investment of Time & Resources 

The development of ML models is a complex task, and the procedure of creating the model, its operations, monitoring and debugging, all require investment of time and resources such as human resources, infrastructural and technological support, monetary resources etc. Thus, the initial costs associated with the creation and application of ML models can be quite high and hence inconvenient for small enterprises to integrate with their operations. 

3) Difficulties in Interpretation 

The difficulties associated with the interpretation of complex results produced by machine learning models can be a daunting task for businesses and professionals. Since the results provided by the model can be complex and hence difficult to interpret accurately, it may lead to a creation of distrust on automated models as well as solutions provided by it for business growth. Another major concern to take care of is the utilisation of the right model or algorithm based on the type of dataset used for training and the purpose of the interpretations of the results. All such factors require specialised skills and expertise in machine learning to maximise the potential of these models, thus contributing to the inconvenience associated with the use of such models.

4) High Susceptibility to Errors

 A major concern associated with the usage of ML models is their high susceptibility to errors. These errors can occur at multiple levels. While ML models and algorithms are trained to make accurate predictions, there is less emphasis placed on the active applicability of such predictions. This can result in erroneous functioning and outputs by the model, especially if the model is trained on the basis of ineffective, small or unsuitable data. This can lead to the model continuing to train on inaccurate datasets, leading to unuseful and in certain cases, inaccurate predictions and decisions being offered. Moreover, it might lead to biased results being produced by the model, leading to potential ethical concerns as well. Lastly, a major implication of this disadvantage is the difficulty of tracing the error sources in ML models. As such errors have high chances of going undetected for large durations of time, the tracking of the error source is highly tough in such situations. 

5) Concerns of Data Privacy 

Associated with the widespread application of ML models is the requirement for large and meaningful datasets. The requirement for such large databases and datasets can have potential implications on the security and privacy of user data. In many cases, business ventures and enterprises utilise customer and user data to train such models, creating potential threats to their security and privacy. Unless enterprises and companies are using sufficient safeguards to protect user privacy and cybersecurity, the use of ML models on such datasets poses significant threats to the cyber well-being of users and customers. This is especially true if there is unmonitored access to such datasets and findings, allowing for easy misuse of the data. 

6) Impact of Automation 

While one can focus on the major benefits of automation to cost-saving and efficiency of functioning, such automation inevitably leads to the redundancy of a number of job roles and impacts human employability, even for complex analytical functions. As a result, this is one of the major concerns associated with the widespread employability of ML models. 

7) Ethical Concerns 

One of the primary problems associated with the functioning of ML technologies is its susceptibility to amplify existing biases in the training data. When biased or poor quality datasets guide the training of a machine learning model, it can lead to further perpetuation of those biases, which can raise many ethical concerns related to discrimination, stereotyping, data privacy and so on. This is another major disadvantage associated with the application of ML on a widespread basis. 

Conclusion: Is Machine Learning Worth the Hype? 

Having looked at the various advantages and disadvantages associated with machine learning, it is quite apparent that while this technology holds tremendous potential for transforming the face of artificial intelligence and computer science, it still suffers some significant limitations in its applications and effectiveness in providing solutions. 

When used in an unsupervised and insufficient capacity of interpretation, the threats of biased outputs and discriminatory implications surge. As a result, the full potential of ML technologies can only be realised with the creation of more robust models and utilisation of effective datasets that are of high quality.
