A Shared Vision for Machine Learning in Neuroscience

August 30, 2022


There is a lot of excitement about machine learning (ML). After all, it has enabled computers to outperform people in picture classification, defeat humans in complicated games like "Go" and give high-quality voice-to-text on popular mobile phones. The scientific community is taking notice of advances in machine learning.

The discipline of neurology is no different. Many opinion pieces have been written in recent years regarding the relevance of machine learning in neuroscience. Furthermore, when we look at the number of new findings concerning ML in neuroscience over the previous 20 years, we see that its application has been steadily increasing. Within this discipline, machine learning has been employed in a variety of ways. 

We will catalog the uses of ML in neuroscience as well as the shared goal for ML in neuroscience in this blog.

Objectives of Machine Learning

Humans can observe and experience the environment because of the eyes. Humans make judgments depending on what they observe with their eyes. Humans act on their ideas depending on what they perceive with their eyes. Similarly, in order for a Machine learning model to emulate human intellect, it must have eyes that can capture pictures or have data as input and make decisions based on them. 

Hence, the main objective of machine learning is to uncover patterns in user data and then generate predictions based on these complicated patterns to answer real-world queries and solve issues. 

Objectives of Neuroscience

Neuroscience is the study of how the brain performs diverse perceptual, cognitive, and motor processes. 

There are many objectives of Neuroscience, few of them are

  • To use the scientific method to construct feasible independent research projects by integrating content, skills, and critical thinking. 
  • To gain a wide awareness of the nervous system's structure and function, as well as the depth of knowledge in cellular/molecular or behavioral/cognitive perspectives. 
  • To get a better grasp of the ethical problems surrounding the use of human subjects and animal subjects in neuroscience research.

And since the advent of new technologies neuroscience is exploring its new horizons. Big data can now be processed by intelligent computers using ML-based artificial intelligence approaches, opening up new possibilities for neuroscience such as how millions of neurons and nodes cooperate to manage vast amounts of information and how the brain develops and governs actions.

From Neuroscience to ML

The advantages of thoroughly analyzing biological intelligence for constructing machine learning models are twofold. 

  • First, neuroscience is a rich source of inspiration for new sorts of algorithms and architectures that are independent of and complementary to the mathematical and logic-based methodologies and concepts that have dominated traditional approaches to Machine Learning. For example, if a novel aspect of biological computing is shown to be crucial to supporting a cognitive function, we would consider it a good candidate for inclusion in machine learning systems. 

  • Second, neuroscience can give validation for existing machine learning algorithms. If a known algorithm is later discovered to be implemented in the brain, it provides strong support for its viability as an important component of a larger general intelligence system.

Human intellect is distinguished by an extraordinary capacity to keep and alter data in an active storage, this is referred to as working memory, and it is assumed to be instantiated inside the prefrontal cortex and related regions. According to traditional cognitive theories, this functioning is dependent on interactions between a central controller ("executive") and distinct, domain-specific memory buffers (e.g. visuo-spatial sketchpad). These models have inspired machine learning research, which has resulted in systems that explicitly preserve information across time. Historically, such attempts began with the introduction of recurrent neural network topologies with attractor dynamics and rich sequential activity, work that was inspired directly by neuroscience. This study paved the way for later, more thorough models of human behavior.

In difficult object identification tests, machine learning systems now match and exceed professional humans. Machines can make synthetic natural visuals and human speech simulations that are nearly indistinguishable from their real-world counterparts, translate across several languages, and create "neural art" in the style of well-known painters.

Much effort has to be done to close the IQ gap between machines and humans. Concepts from neuroscience will become more important in narrowing this gap. The introduction of new technologies for brain imaging and genetic bioengineering in neuroscience has begun to give a precise characterization of the computations occurring in neural networks, suggesting a revolution in our knowledge of mammalian brain function. The importance of neuroscience in the following main areas, both as a roadmap for the ML research agenda and as a supply of computational tools, cannot be overstated.

From ML to Neuroscience

Psychologists and neuroscientists frequently have only hazy ideas about the mechanisms behind the issues they examine. Machine learning is aiding them by formalizing these notions in a quantitative language and providing insights into their requirement and adequacy (or lack thereof) for intelligent action.

RL is an excellent example of its potential. After ideas from animal psychology aided in the development of reinforcement learning research, essential principles from the latter were fed back into neuroscience. In another area, research aimed at improving the performance of CNNs has revealed fresh insights into the nature of neural representations in high-level visual domains.

Machine learning research is also generating new ideas on how the brain may implement an algorithmic counterpart to backpropagation, the crucial technique that permits weights to be optimized over numerous layers of a hierarchical network toward a certain purpose 

When taken together, machine learning models hold out the prospect of identifying processes through which the brain may implement algorithms. Furthermore, these studies demonstrate the possibility of synergistic interactions between machine learning and neuroscience: study targeted towards biological development.


When planning for future collaboration between the two domains, it is vital to remember that previous contributions of neuroscience to ML have seldom entailed a straightforward transfer of full-fledged solutions that could be directly re-implemented in machines. Rather, neuroscience has been beneficial in a more subtle way, prompting algorithmic-level questions about aspects of animal learning and intelligence of interest to machine learning and offering preliminary leads toward relevant processes.

In the future, we hope that increased collaboration between neuroscience and machine learning, as well as the identification of a common language between the two fields will enable a virtuous circle in which research is accelerated through shared theoretical insights and common empirical advances. 

We think that the pursuit of machine learning will eventually lead to a greater understanding of our own minds and mental processes. Distilling intelligence into an algorithmic construct and comparing it to the human brain may reveal insights into some of the mind's most profound and persistent mysteries, such as the source of creativity, dreams, and, possibly one day, consciousness.

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.
