LLMs in Hindi: The Future of Customer Service Chatbots

February 22, 2024

As we have all experienced, chatbots are now an essential part of the customer service in most companies – providing quick, convenient, and personalized support to people across various channels. However, most chatbots are still limited by their language capabilities, especially when it comes to non-English languages. Hindi for example, has over 571 million speakers, mostly in India. And very few chatbots are yet fluent in Hindi.

For my readers who need an introduction to LLMs, here’s a brief one: LLMs are a type of artificial intelligence (AI) algorithm that can process and understand human languages using neural network techniques and self-supervised learning. LLMs can handle a wide range of tasks, such as text generation, machine translation, summary writing, image generation from texts, machine coding, chatbots, and conversational AI.

One of the most promising applications of LLMs is in the field of customer service chatbots, especially for languages that are underrepresented in the current chatbot landscape, such as Hindi. Firms like Bhashini, OpenHathi, and Krutim are now paving the way for LLMs in the Hindi language.

Let's discuss the possibilities in more detail.

Multilingual Capabilities Using NLP Techniques

LLMs leverage advanced NLP techniques to comprehend the intricacies of Hindi and other Indian languages. For instance, by employing word embeddings and language models, these chatbots can understand the context, sentiment, and intent behind user queries. This enables them to respond accurately, addressing user concerns in a language that resonates with the users' cultural and linguistic preferences.

Generative AI for Natural and Engaging Conversations

Generative AI in LLMs enables chatbots to produce responses that mimic human-like conversation. By analyzing vast amounts of text data, these models can generate contextually relevant and coherent responses. To illustrate, if a user inquires about product specifications, the chatbot can generate detailed and informative replies, creating a conversational experience that feels more personalized and engaging. You could, for example, ask which is the best birthday gift for your five-year-old daughter – and the chatbot will give a range of options, from birthday cakes to craft kits.

Handling Complex Queries and Tasks

LLMs empower chatbots to handle complex queries and tasks seamlessly. Consider a scenario where a user asks for travel recommendations for the summer holidays (within India) – the chatbot can analyze the user’s preferences, budget constraints, and past travel history to suggest personalized travel options. Say the user has traveled to the hill stations Dehradun and Shillong before; based on that information, the chatbot can recommend the next travel destination as a choice between Ladakh, Mussoorie and Darjeeling. 

Moreover, these models can facilitate transactions like hotel bookings or payment processing, showcasing a robust problem-solving and task-execution capability in customer service-driven scenarios.

  • Product Recommendations: LLM-powered chatbots can analyze user preferences, purchase history, and real-time trends to offer personalized product recommendations. For instance, if you have expressed interest in going to a wedding reception, the chatbot can intelligently suggest relevant items, including lehengas, dupattas, and jewelry – thereby creating a tailored shopping experience.
  • Bookings and Reservations: When users inquire about booking services like hotels or flights, LLM-driven chatbots can navigate through available options, consider user preferences, and seamlessly facilitate the booking process. For example, if the user tends to fly economy class, then the chatbot can recommend the best airfares. This ensures a smooth and efficient transaction, enhancing the overall customer experience.
  • Payment Processing: LLMs enable chatbots to handle complex payment-related queries, such as providing information on payment methods (credit card vs debit for example), guiding users through transaction processes, and addressing payment-related concerns (like credit limit). This capability contributes to a secure and user-friendly financial interaction within the chatbot interface.
  • Feedback Collection: Chatbots equipped with LLMs can effectively gather user feedback by engaging in dynamic conversations. For example, after a transaction or service interaction, the chatbot can intelligently solicit feedback, understanding and responding to user sentiments, thereby contributing to the improvement of services.

Adaptability to Regional Dialects

The adaptability of LLMs to regional dialects within Hindi and other Indian languages is exemplified by their ability to understand colloquial expressions and local variations. For instance, a user from Bihar might use different phrases compared to someone from Maharashtra. The chatbot's linguistic adaptability ensures that it can understand and respond effectively to users across diverse linguistic landscapes, fostering a more inclusive and user-friendly experience.

  • Colloquial Expressions: Chatbots, powered by LLMs, showcase an understanding of colloquial expressions commonly used in different regions. For instance, a user might inquire about a product with a local term specific to their region, and the chatbot can intelligently respond, demonstrating its grasp of regional linguistic nuances.
  • Linguistic Variations: LLMs enable chatbots to interpret linguistic variations within Hindi, such as different pronunciations, vocabulary, and sentence structures. For example, a user from Uttar Pradesh might phrase a question differently than someone from Punjab. The chatbot, with its linguistic adaptability, can accurately interpret and respond to these diverse linguistic inputs.
  • Contextual Understanding: The adaptability of LLMs goes beyond literal translations; they understand the contextual significance of words and phrases within specific regions. This allows chatbots to respond appropriately to regional contexts, ensuring that the conversation remains not only linguistically accurate but also culturally resonant.

Continuous Learning for Improved Performance

LLMs employ continuous learning mechanisms, allowing chatbots to evolve and improve over time. If users consistently ask specific questions or use certain phrases, the chatbot can adapt and refine its responses based on this ongoing feedback. This iterative learning process ensures that the chatbot remains up-to-date and adept at addressing changing customer preferences and inquiries.

Closing Words

Chatbots are a convenient way to interact with a business. And the number of users using chatbots is growing by the day.

The future of customer service chatbots is one where Hindi-language chatbots will soon become widespread. By leveraging the power of artificial intelligence, neural networks, and self-supervised learning, LLMs in Hindi will be able to create chatbots that can understand and generate natural and fluent text in one of the most widely spoken languages in the world. 

New advancements in Hindi-language LLMs will involve better contextual understanding of India and our culture and traditions, allowing chatbots to grasp subtleties in user queries better and better over time.

Image-based 3D Object Reconstruction State-of-the-Art and trends in the Deep Learning Era

3D reconstruction is one of the most complex issues of deep learning systems. There have been multiple types of research in this field, and almost everything has been tried on it — computer vision, computer graphics and machine learning, but to no avail. However, that has resulted in CNN or convolutional neural networks foraying into this field, which has yielded some success.

The Main Objective of the 3D Object Reconstruction

Developing this deep learning technology aims to infer the shape of 3D objects from 2D images. So, to conduct the experiment, you need the following:

  • Highly calibrated cameras that take a photograph of the image from various angles.
  • Large training datasets can predict the geometry of the object whose 3D image reconstruction needs to be done. These datasets can be collected from a database of images, or they can be collected and sampled from a video.

By using the apparatus and datasets, you will be able to proceed with the 3D reconstruction from 2D datasets.

State-of-the-art Technology Used by the Datasets for the Reconstruction of 3D Objects

The technology used for this purpose needs to stick to the following parameters:

  • Input

Training with the help of one or multiple RGB images, where the segmentation of the 3D ground truth needs to be done. It could be one image, multiple images or even a video stream.

The testing will also be done on the same parameters, which will also help to create a uniform, cluttered background, or both.

  • Output

The volumetric output will be done in both high and low resolution, and the surface output will be generated through parameterisation, template deformation and point cloud. Moreover, the direct and intermediate outputs will be calculated this way.

  • Network architecture used

The architecture used in training is 3D-VAE-GAN, which has an encoder and a decoder, with TL-Net and conditional GAN. At the same time, the testing architecture is 3D-VAE, which has an encoder and a decoder.

  • Training used

The degree of supervision used in 2D vs 3D supervision, weak supervision along with loss functions have to be included in this system. The training procedure is adversarial training with joint 2D and 3D embeddings. Also, the network architecture is extremely important for the speed and processing quality of the output images.

  • Practical applications and use cases

Volumetric representations and surface representations can do the reconstruction. Powerful computer systems need to be used for reconstruction.

Given below are some of the places where 3D Object Reconstruction Deep Learning Systems are used:

  • 3D reconstruction technology can be used in the Police Department for drawing the faces of criminals whose images have been procured from a crime site where their faces are not completely revealed.
  • It can be used for re-modelling ruins at ancient architectural sites. The rubble or the debris stubs of structures can be used to recreate the entire building structure and get an idea of how it looked in the past.
  • They can be used in plastic surgery where the organs, face, limbs or any other portion of the body has been damaged and needs to be rebuilt.
  • It can be used in airport security, where concealed shapes can be used for guessing whether a person is armed or is carrying explosives or not.
  • It can also help in completing DNA sequences.

So, if you are planning to implement this technology, then you can rent the required infrastructure from E2E Networks and avoid investing in it. And if you plan to learn more about such topics, then keep a tab on the blog section of the website

A Comprehensive Guide To Deep Q-Learning For Data Science Enthusiasts

For all data science enthusiasts who would love to dig deep, we have composed a write-up about Q-Learning specifically for you all. Deep Q-Learning and Reinforcement learning (RL) are extremely popular these days. These two data science methodologies use Python libraries like TensorFlow 2 and openAI’s Gym environment.

So, read on to know more.

What is Deep Q-Learning?

Deep Q-Learning utilizes the principles of Q-learning, but instead of using the Q-table, it uses the neural network. The algorithm of deep Q-Learning uses the states as input and the optimal Q-value of every action possible as the output. The agent gathers and stores all the previous experiences in the memory of the trained tuple in the following order:

State> Next state> Action> Reward

The neural network training stability increases using a random batch of previous data by using the experience replay. Experience replay also means the previous experiences stocking, and the target network uses it for training and calculation of the Q-network and the predicted Q-Value. This neural network uses openAI Gym, which is provided by taxi-v3 environments.

Now, any understanding of Deep Q-Learning   is incomplete without talking about Reinforcement Learning.

What is Reinforcement Learning?

Reinforcement is a subsection of ML. This part of ML is related to the action in which an environmental agent participates in a reward-based system and uses Reinforcement Learning to maximize the rewards. Reinforcement Learning is a different technique from unsupervised learning or supervised learning because it does not require a supervised input/output pair. The number of corrections is also less, so it is a highly efficient technique.

Now, the understanding of reinforcement learning is incomplete without knowing about Markov Decision Process (MDP). MDP is involved with each state that has been presented in the results of the environment, derived from the state previously there. The information which composes both states is gathered and transferred to the decision process. The task of the chosen agent is to maximize the awards. The MDP optimizes the actions and helps construct the optimal policy.

For developing the MDP, you need to follow the Q-Learning Algorithm, which is an extremely important part of data science and machine learning.

What is Q-Learning Algorithm?

The process of Q-Learning is important for understanding the data from scratch. It involves defining the parameters, choosing the actions from the current state and also choosing the actions from the previous state and then developing a Q-table for maximizing the results or output rewards.

The 4 steps that are involved in Q-Learning:

  1. Initializing parameters – The RL (reinforcement learning) model learns the set of actions that the agent requires in the state, environment and time.
  2. Identifying current state – The model stores the prior records for optimal action definition for maximizing the results. For acting in the present state, the state needs to be identified and perform an action combination for it.
  3. Choosing the optimal action set and gaining the relevant experience – A Q-table is generated from the data with a set of specific states and actions, and the weight of this data is calculated for updating the Q-Table to the following step.
  4. Updating Q-table rewards and next state determination – After the relevant experience is gained and agents start getting environmental records. The reward amplitude helps to present the subsequent step.  

In case the Q-table size is huge, then the generation of the model is a time-consuming process. This situation requires Deep Q-learning.

Hopefully, this write-up has provided an outline of Deep Q-Learning and its related concepts. If you wish to learn more about such topics, then keep a tab on the blog section of the E2E Networks website.

GAUDI: A Neural Architect for Immersive 3D Scene Generation

The evolution of artificial intelligence in the past decade has been staggering, and now the focus is shifting towards AI and ML systems to understand and generate 3D spaces. As a result, there has been extensive research on manipulating 3D generative models. In this regard, Apple’s AI and ML scientists have developed GAUDI, a method specifically for this job.

An introduction to GAUDI

The GAUDI 3D immersive technique founders named it after the famous architect Antoni Gaudi. This AI model takes the help of a camera pose decoder, which enables it to guess the possible camera angles of a scene. Hence, the decoder then makes it possible to predict the 3D canvas from almost every angle.

What does GAUDI do?

GAUDI can perform multiple functions –

  • The extensions of these generative models have a tremendous effect on ML and computer vision. Pragmatically, such models are highly useful. They are applied in model-based reinforcement learning and planning world models, SLAM is s, or 3D content creation.
  • Generative modelling for 3D objects has been used for generating scenes using graf, pigan, and gsn, which incorporate a GAN (Generative Adversarial Network). The generator codes radiance fields exclusively. Using the 3D space in the scene along with the camera pose generates the 3D image from that point. This point has a density scalar and RGB value for that specific point in 3D space. This can be done from a 2D camera view. It does this by imposing 3D datasets on those 2D shots. It isolates various objects and scenes and combines them to render a new scene altogether.
  • GAUDI also removes GANs pathologies like mode collapse and improved GAN.
  • GAUDI also uses this to train data on a canonical coordinate system. You can compare it by looking at the trajectory of the scenes.

How is GAUDI applied to the content?

The steps of application for GAUDI have been given below:

  • Each trajectory is created, which consists of a sequence of posed images (These images are from a 3D scene) encoded into a latent representation. This representation which has a radiance field or what we refer to as the 3D scene and the camera path is created in a disentangled way. The results are interpreted as free parameters. The problem is optimized by and formulation of a reconstruction objective.
  • This simple training process is then scaled to trajectories, thousands of them creating a large number of views. The model samples the radiance fields totally from the previous distribution that the model has learned.
  • The scenes are thus synthesized by interpolation within the hidden space.
  • The scaling of 3D scenes generates many scenes that contain thousands of images. During training, there is no issue related to canonical orientation or mode collapse.
  • A novel de-noising optimization technique is used to find hidden representations that collaborate in modelling the camera poses and the radiance field to create multiple datasets with state-of-the-art performance in generating 3D scenes by building a setup that uses images and text.

To conclude, GAUDI has more capabilities and can also be used for sampling various images and video datasets. Furthermore, this will make a foray into AR (augmented reality) and VR (virtual reality). With GAUDI in hand, the sky is only the limit in the field of media creation.
