Generative AI is the new emerging era

November 15, 2022

It’s interesting that we talk about the metaverse frequently and there is a lot to build there obviously but AI in the past couple of years has started another level of creative diffusion and we are making incredible art & images. We are creating stuff like videos and the implications are really staggering because of that.

What does it mean to have AI as a creator?

Have you ever thought how mystical it is about artificial intelligence when technological growth is insanely rising? AI today is not only creating videos, it is curing diseases like cancer, shifting from interpreting existing data to generating novel content at scale. 

AI is effecting following areas at a different level:

– Unsupervised Learning: Removing the barriers to labeled and segregated data used by conventional AI models. Advanced AI algorithms are now trained via real data without any structure & human involvement.

– Transformers: Recurrent neural networks, RNNs perform data processing sequentially. They may be put in place of Transformers in the coming future. 

– Neural Network Compression: Deep learning models are usually huge and it becomes important to reduce them. Compressing them would make the neural networks work efficient as they will become smaller and easy to use.

What are GANs?

GAN or generative adversarial networks puts two AI models off against each other. Most machine learning models are used to generate a prediction. 

Generative AI
  • It gets started with some input training data which we feed into the model. 
  • A model then makes a prediction in the form of output and we can compare the predicted output with the expected output from the training data set and then based upon that expected output and the actual predicted output, we can figure out how we should update our model to create better outputs. 
  • It is an example of supervised learning. A GAN is an example of unsupervised learning, it effectively supervises itself, and it consists of two submodels. One is a generator submodel & other is a discriminator submodel. 
  • Now, the generator’s job is to create fake inputs or fake samples and the discriminator's job is to take a given sample & figure out if it is a fake sample or if it’s the real sample from the domain and therein lies the adversarial nature of this. 
  • We have a generator creating fake samples and sending them to a discriminator. The discriminator is taking a look at the given sample and figuring out “Is this the fake sample from the generator?” or “Is this a real sample from the domain set”?. Now, this sort of scenario is often applied in image generation. There are images all over the internet of generators that have been used to create fake 3D models, fake faces, fake cats and so forth. So this really works by the generator iterating through a number of different cycles for creating samples, updating its model & so forth until it can create a sample that is so convincing that it can fool a discriminator and also fool us. 

Example 1: A flower, we are going to train a generator to create really convincing fake flowers. We can start doing this, we will train our discriminator model to recognize what a picture of a flower looks like. 

So, our domain is “lots of pictures of flowers” and we will be feeding this into our discriminator model telling it to look at all attributes that makeup those flower images. Take a look at the colors, the shading, the shapes and so forth. 

And when our discriminator gets good at recognizing real flowers, then we will feed in some shapes that are not flowers at all & make sure that it can discriminate those as-being not flowers. Now, this whole time our generator here was frozen, it wasn’t doing anything but our discriminator is now good at recognizing things from our domain, then we apply our generator to start creating fake versions of those things. 

So, a generator is going to take a random input vector and it is going to use that to create its own fake flower. Now, this fake flower image is sent to the discriminator & the discriminator has a decision to make: “Is that image of a flower, the real thing from the domain or is it a fake from the generator?  Now, The answer is revealed to both the generator and discriminator. The flower was fake and based upon that, the discriminator & generator will change their behavior. It will declare the winner & loser, the winner has to remain blissfully unchanged whereas the loser has to update its model. This is how a generative adversarial network directs the process to choose one thing amongst various options in machine learning.

Example 2: What happens when we can actually use deep nuts to compose a whole paragraph and we may give you an interface that may give you a few suggestions but suggestion actually is multiple sentences so this becomes optimal in the form of AI. The software generating the content from google or the dedicated apps are far better than what we can do by ourselves manually.

A generative adversarial network is a class of machine learning frameworks for training generative models. Generative models create new data instances that resemble the training data.

What is Generative AI?

Artificial Intelligence has endowed us with limitless possibilities from intelligent marketing to fraud prevention & 24*7 customer support. AI has transformed every aspect of businesses and lives. Today, it can also enable machines to use textual or visual data to create new content via Generative AI. 

Generative AI refers to the advancement of artificial intelligence-enabled machines to use existing text, audio files, or images to create new content. It has a workflow that runs on algorithms & identifies the underlying pattern of an input to generate similar content.

Benefits of Generative AI

  • Improved quality of outputs
  • Lower risks
  • Reduced bias
  • Localization of content
  • Comprehend abstract concepts

Applications of Generative AI

  • Protection of Identity: Generative AI helps to maintain the anonymity of individuals through avatars. It helps organizations maintain unbiased recruitment processes and researchers to provide results that have no unethical favor, which is neutral in terms of judgment.
  • Processed Images: Intelligent processing of low-resolution images to create clearer and more detailed images is the result of great tech upgrades in AI. The process helps in the restoration of old images and old movies.
  • Audio Synthesis: Generative AI goes hand in hand with NLP, natural language processing. It can copy human voice and regenerate it following the specifications. This computer-generated voice is useful for creating video voice over, narrations, and other audible solutions for organizations. 
  • Client Segmentation: Generative AI helps to segment target groups for your marketing campaigns. It studies your data to predict their response to your promotions and advertisements. It can drive customer based relationships and push them to sustain as loyal customers in the brand forever.

So, this is how generative AI is making a great change to envision artificial intelligence in the coming years. Do you want to explore the subfields of AI like machine learning, deep learning, neural networks etc. Check our blogs here:

A Complete Guide To Customer Acquisition For Startups

Any business is enlivened by its customers. Therefore, a strategy to constantly bring in new clients is an ongoing requirement. In this regard, having a proper customer acquisition strategy can be of great importance.

So, if you are just starting your business, or planning to expand it, read on to learn more about this concept.

The problem with customer acquisition

As an organization, when working in a diverse and competitive market like India, you need to have a well-defined customer acquisition strategy to attain success. However, this is where most startups struggle. Now, you may have a great product or service, but if you are not in the right place targeting the right demographic, you are not likely to get the results you want.

To resolve this, typically, companies invest, but if that is not channelized properly, it will be futile.

So, the best way out of this dilemma is to have a clear customer acquisition strategy in place.

How can you create the ideal customer acquisition strategy for your business?

  • Define what your goals are

You need to define your goals so that you can meet the revenue expectations you have for the current fiscal year. You need to find a value for the metrics –

  • MRR – Monthly recurring revenue, which tells you all the income that can be generated from all your income channels.
  • CLV – Customer lifetime value tells you how much a customer is willing to spend on your business during your mutual relationship duration.  
  • CAC – Customer acquisition costs, which tells how much your organization needs to spend to acquire customers constantly.
  • Churn rate – It tells you the rate at which customers stop doing business.

All these metrics tell you how well you will be able to grow your business and revenue.

  • Identify your ideal customers

You need to understand who your current customers are and who your target customers are. Once you are aware of your customer base, you can focus your energies in that direction and get the maximum sale of your products or services. You can also understand what your customers require through various analytics and markers and address them to leverage your products/services towards them.

  • Choose your channels for customer acquisition

How will you acquire customers who will eventually tell at what scale and at what rate you need to expand your business? You could market and sell your products on social media channels like Instagram, Facebook and YouTube, or invest in paid marketing like Google Ads. You need to develop a unique strategy for each of these channels. 

  • Communicate with your customers

If you know exactly what your customers have in mind, then you will be able to develop your customer strategy with a clear perspective in mind. You can do it through surveys or customer opinion forms, email contact forms, blog posts and social media posts. After that, you just need to measure the analytics, clearly understand the insights, and improve your strategy accordingly.

Combining these strategies with your long-term business plan will bring results. However, there will be challenges on the way, where you need to adapt as per the requirements to make the most of it. At the same time, introducing new technologies like AI and ML can also solve such issues easily.

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.
