Data Science & AI based optimal advancement in scientific programming

June 21, 2022

Many scientists and researchers nowadays spend as much time staring at a computer screen as they do staring at their research lab samples. For example, geologists' job is to study geological formations but in such technological advancement days they spend a huge proportion of their time staring at a computer screen, and many modern hydrologists spend considerably more time developing code and scraping databases than wading in rivers. 

This is science in the twenty-first century. The research process is getting more efficient, speedier, and repeatable. It's a world where scientists from all disciplines use the same tool: scientific programming. 

This blog will introduce scientific programming and will brief you on why scientists nowadays are learning to code and to reap the benefits of clean and reproducible coding practices for open science.

This blog also focuses on the practical elements of data science and artificial intelligence in scientific programs, such as optimizations, deep learning, recommendation systems, and real-world applications.

What is Scientific Programming?

Scientific programming has a basic description that encompasses a wide range of applications and businesses. But in simple words, it is defined as the use of a computer program, leveraging computing power and utilizing algorithms for scientific study.

AI and data science optimizing scientific programming

1.  Optimizing the Borrowing Limit and Interest Rate using Artificial intelligence: 

Artificial intelligence systems may optimize specific parameters in challenges characterized by data flows. AI employs a three-layer BP neural network algorithm to estimate the borrowing limit and interest rate when consumers use a P2P online service to borrow money. Given the restricted information, this technique gives a fresh emphasis to borrowers to estimate and optimize the borrowing limit and interest rate. Furthermore, both parameters are optimized using an algorithmic approach in which a neural network and a genetic algorithm collaborate to address single-target and dual-target programming optimization issues. The success rate here is evaluated on real-world data to determine its suitability as a high-accuracy prediction approach.

2.  Making Use of Image Visual Features in a Content-Based Recommender System:

Data and intelligent algorithms for collaborative filtering address the challenge of researching latent information in huge datasets, from which recommender systems make predictions or suggestions based on the users' preferences. This work's knowledge field is highly important currently since many online systems record useful information about users' behavior while seeking things. These systems include not just e-commerce platforms, but also movies and academic databases.

Although recommender systems primarily evaluate user-item rating data, this study adds item hybrid characteristics based on image visual features to offer a unique recommendation model that may also be used in rating-based recommender situations. This model is very beneficial in sparse data settings, where it outperforms other standard techniques.

3. An Artificial Bee Colonies algorithm with Random Location Updating:

The algorithm named artificial bee colony  (ABC) is a novel metaheuristic algorithm inspired by the complex honey gathering technique of bees. Such an optimization approach has been widely and effectively employed to solve complicated optimization issues in a variety of application sectors. The ABC algorithm's core may be tweaked to improve the exploration phase and, as a consequence, boost convergence speed and solution quality. For that purpose, the original perturbation function is updated by incorporating random location updates, which can broaden the search range of novel solutions and increase the algorithm's exploration capabilities.

4. A Novel Nonlinear Continuous Optimization Algorithm: Application to Feed-Forward Neural Network Training:

Artificial neural networks are a critical approach in the field of artificial intelligence; they have played a significant role in solving a variety of classification, prediction, optimization, and identification challenges. However, the successful operation of neural networks is unquestionably dependent on good training, which is often carried out using the well-known backpropagation technique. To estimate the network heights, the algorithm computes the sum square error(gradient of error). Using this strategy, however, often entails delayed convergence and slipping into local minima. Metaheuristics are frequently used to address this issue. Also, a modified particle swarm optimization (PSO) method can be used for training multilayer feed-forward artificial neural networks.

The key difference between the original PSO and this one is that the utilized algorithm employs many swarms rather than a single one as in the classic PSO. This allows one to limit the number of particles leaving the search space while also strengthening the local search of each particle. Findings have shown that suggested methods have improved the accuracy of the classification done by these multilayer feed-forward neural networks. 

5. The Use of Polyhedral Conic Functions in Text Classification and Comparative Analysis:

The purpose of classifying texts into predetermined classifications is the work in the field of text categorization Because of the massive rise in internet data over the previous few years, this subject of expertise is particularly interesting nowadays. In a recent study, many common supervised algorithms, including logistic regression, SVMs or support vector machines, and Bayesian Networks, have been introduced to deal with the challenge. On this premise, the scientists investigate polyhedral conic function (PFC) approaches as supervised classification functions in addition to typical supervised procedures. They specifically propose using PCFs to handle binary and multiclass text classification challenges. The performance is assessed by solving the complex structure of real-world datasets from the literature and analyzing f-measure, accuracy, and execution time. In conclusion, the classification algorithms based on PFCs produce 2 Scientific Programming more promising outcomes than typical supervised algorithms.

6. Railway Subgrade Defect Automatic Recognition Method Based on Faster R-CNN Improvements:

Because of the variation in defect shape and size, as well as the amount of data produced by measuring systems, such as the vehicle-mounted ground penetrating radar (GPR), which is the most important technology today, defect detection is a difficult process. Because of this variability, most efforts in this area concentrate on classic machine-learning algorithms, where feature representation fails for subgrade faults. Furthermore, while deep-learning algorithms were launched in the railway industry, they were not used to detect subgrade faults. Based on this, the authors suggest a deep-learning technique for detecting errors in the GPR profile. To that aim, they offer a method for using quicker R-CNN to detect railway subgrade problems automatically. Experiments in a real-world context indicate that the idea outperforms a classic strategy based on a support vector machine and a histogram of directed gradients.

7. High-Frequency Trading in the Emerging Indian Stock Market:

The purpose of high-frequency trading is to develop, construct, and test a completely autonomous system that can function in a tiny market with highly concentrated ownership, such as the Indian stock market. A high-frequency trading system is demonstrated using powerful computer tools and represented as an NP-Complete issue. Separate tests on the developed algorithms are performed, analyzing the return i.e. profitability that may be fitted to some of the most recent weeks, months, and terms of real market data. The usage of particle swarm optimization as an optimization technique is demonstrated to be an effective solution since it can optimize a collection of different variables but is limited to a certain domain, resulting in a significant improvement in the final solution.


From geologists to zoologists, all scientists may profit from scientific programming. A researcher may dramatically boost the rate and reproducibility of their work by using Data Science & AI-based optimal advancement in scientific programming. While people are undoubtedly superior to computers in some areas, computers were built to do complex computations, store data, and analyze outcomes. In the coming future Scientists will utilize data and artificial intelligence algorithms at an increased level to automate operations that would otherwise take a long time, be laborious, error-prone, and difficult for humans to complete.

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.
