Chatbots/Natural Language Processing (NLP) are a type of conversational neural network AI that is revolutionizing the way companies interact with their customers and run their business. With the ability to understand natural language and respond in real-time, chatbots are becoming increasingly popular across a range of industries, including finance, healthcare, and e-commerce. Let’s explore how chatbots are being used, the benefits they offer, and the potential risks.

 

HOW DOES IT WORK?

​

Natural language processing (NLP) & Large Language Models (LLM) are subfields of artificial intelligence that aim to enhance the interaction between humans and computers by enabling computers to comprehend, interpret, and generate human language.

To achieve this goal, natural language models are developed using machine learning techniques specifically process natural language. These models undergo training using large datasets of human language, which allows them to identify patterns and relationships within the language. Among the various types of natural language models, the transformer model is one of the most commonly used. This model, introduced in 2017 by a team at Google Brain, forms the basis for many powerful natural language models, including the GPT model. The transformer model functions based on the concept of self-attention, which permits the model to weigh the importance of various components of the input sequence when making predictions. Consequently, the model captures long-range dependencies and makes predictions based on the context of the entire input sequence.

An illustration of the transformer model's application is language translation. By numerically tokenizing the input sentence into numerical representations of individual words or sub-words, the natural language model generates a sequence of hidden representations that capture the meaning of each token. The model utilizes self-attention to determine the significance of each hidden representation, enabling the identification of the most critical words for generating the translation. The output sequence comprises a sequence of tokens in the target language, generated based on the model's training to generate the most plausible translation by utilizing assigned  probabilities. For instance, suppose you ask the model to process the sentence "I did not get the deposit I made into my account today". In that case, the model must accurately determine that "deposit" and "account" have various meanings. For instance, "deposit" can refer to a layer of natural sand, rock, coal, or other material, while "account" can mean a description or report. However, in this specific context, these terms represent money that should be reflected in the customer's account balance.

Beyond language translation, natural language processing and large language models have a wide range of applications in fields such as search engines, chatbots, and sentiment analysis. As such, natural language models are powerful tools with the potential to revolutionize human-computer interaction. Let's explore more applications for this technology as well as its benefits and risks.

APPLICATIONS

Customer service: 

Companies can use AI chatbots to handle customer queries and complaints in a timely and efficient manner. For example, a banking chatbot can provide customers with information on their account balances, recent transactions, and even help them set up new accounts. This eliminates the need for customers to wait on hold for a human representative and allows them to receive immediate assistance. In the retail sector a chatbot on a retail website can help customers with product recommendations, shipping information, and order status updates.

 

Marketing and sales: 

Another key benefit of chatbots is the ability to provide personalized marketing messages and product recommendations based on customers' financial behavior and interests. Chatbots can offer personalized product recommendations to customers based on their financial goals and history. For example, an e-commerce chatbot can help customers find products they are looking for, offer coupons or discounts, and process orders directly within the chat window. In the real estate sector, a chatbot on a real estate website can help customers find their ideal property and schedule a viewing.
 

24/7 Availability: 

Chatbots can be available 24/7, which means that customers can get help whenever they need it, without having to wait for business hours. Additionally, chatbots are cost-effective, as they can handle a large number of inquiries simultaneously, reducing the need for human support staff. Chatbots also have the ability to learn from customer interactions, which means they can continuously improve their responses and offer better service over time.
 

Personal Services:

Individuals can use chatbots for personal use such as personalized banking, personal finance management as well as for Health and wellness. AI chatbots can help users reach their financial goals by analyzing their spending history and preferences to provide personalized financial advice and recommendations. This can help customers make better-informed decisions about their finances and increase the likelihood of achieving their financial goals. For example, a chatbot on a banking app can help customers track their expenses, create a budget, and invest their money. Chatbots can also be used to provide health and wellness advice and support. For example, a chatbot on a fitness app can help users create a personalized workout plan and track their progress or a chatbot on can remind a user to take a mental break based on reading biometric information on their smart watch or device. 
 

Fraud detection: 

Banks, credit card companies, and email providers can leverage AI chatbots to monitor customer activity, transactions, and emails for fraudulent activities and engage with customers about suspicious behavior. By using chatbots, these organizations can swiftly detect any unusual patterns in transactions and emails with confirmation engagement directly with customers. Moreover, chatbots can notify users or the bank's security team for further investigation, helping them to take immediate action against fraudulent activities.
