Unlocking LangChain's Power for Financial Institutions
Let's explore the business opportunities of GenAI, LLms and a framework like Langchain.
Let's look at some categories of use-cases for the Large Language Models linked to real world scenarios.
The four pillars of AI toolkits
Summarizing
Think about at the huge amount of documentation collected in every company, not only simple word files but excel, pdf, video, images, confluence page. Large Language Models can be used to summarize text, images or videos. It can help in saving time and gaining insights from a large volume of content centralizing the search in a single endpoint. These models can be used to summarize documentation of a project, meetings reviews or customer feedbacks, and actions can be automated based on the responses, customize the desired result.
We can create prompts to analyze multiple reviews of the same product or multiple reviews of multiple products. We can also focus on specific aspects of input data for summarization. For example, through prompt engineering, we can summarize customer feedbacks to find about product quality or shipping and handling or operational issues, etc. and automate processing of these feedbacks.
Inferring
Inference involves analyzing input data to extract labels, names, or sentiment. Large Language Models can be used to process data to identify specific entities. They can identify customer sentiments from reviews, topics from articles, etc.
In the example of customer feedbacks, we can create prompts to identify if a customer has posted a feedback about a particular product and build automation around it to route it to specific department.
The benefit of Large Language Models is that we don't need to collect training data, train a model or maintain it. We can perform the task of inference with just some prompt engineering.
Transforming
Large Language Models can be used for transforming text they can perform language translation on real/time by request, spelling and grammar correction, format transformation, and tone transformation, all with just the help of prompts. This capability can be used for internationalization of a website, to recognize offensive words, as an example. Also, Large Language Models can be used in communications and respond to customers more effectively.
Transformation is a very versatile capability of Large Language Models which can have multiple use-cases.
From a technical perspective this could be used also to automatically translate encoded text into human readble text.
Expanding (Augmentation)
Expanding is the task of taking a shorter piece of data, and having generate a longer piece of data from it. It is also named as "augmentation" a tecnique used to increase the number of training or testing material that the model has asvailable.
It takes the tokens from the input and expand or generate tokens that'd follow the ones in the input. This is a very powerful category of use-cases of these models.
We can create prompts to generate content using the Large Language Models. It can be used to create articles, blogs, stories, poems, emails, images, videos, etc. It can have a wide variety of applications, like analyzing healthcare literature and helping with diagnosis, providing students with detailed explanations and answering questions in real-time, helping customers with query resolutions and interact through chatbots, role-playing and helping with brainstorming or interview preparations, etc.
Specific Real Use-Cases in everyday business
Having a framework that is able to seamlessly connecting language models with diverse data sources, is obviovsly powerful.
Its intuitive features allow financial managers to be able composing customized tools that leverage its capabilities without the need for intricate technical engineering expertise.
