Project Title:- Automated Coronary Artery Disease(CAD) diagnosis using ECG signal and convolution neural network 

Student Members:- Abhinav Mishra second year(CS)

Mentor Names:- Dr Shilpa gite, Hariharan Venugopal 

Objectives and methodology:

The primary objective of the project is to distinguish between cad and non-cad patients using ECG signal of their heart using a custom convolution neural network.

To perform cad classification on ECG signal, first, we denoise using wavelet transform, median filter, and low pass Butterworth filter because raw ecg may contain noise like baseline wander, power line interference, motion artifact etc after denoising ECG segmentation was done to increase the dataset and reduce the effect of the noise and then normalization technique is implemented to normalize the individual ecg segment this is to overcome the problem of amplitude scaling and to remove the offset effect .Custom cnn was used to learn the features from input data and a classifier was used to perform classification.

Mentors: Dr.Shilpa Gite & Dr. Shruti Patil

Objectives and Methodology

In times of current pandemic, we have been forced to adopt new digital lifestyles including Online Teaching. Most schools and Universities have shifted their teaching from Offline to Online mode. Though the Study material and the syllabus remain the same but handling an online teaching is still a difficult task as compared to conventional physical classes. This project aims to develop an automated AI tool to create for teachers to understand the emotional state of kids during online school learning to create activities or study methods to bring up their learning moods. To analyse the Emotions from both audio and video, we have divided the project into four categories: DataSet Selection, Visual Facial Emotion Recognition Model and Audio Emotion Recognition Model, Fusion of Predicted data from both Video and Audio Model, respectively. We aim to generate a robust dataset of audio and video clips for implementation. After individual predictions, we will fuse the results and build a software that can detect and classify the emotional state of the end user in real time.

With the recent advancements in Artificial Intelligence, computers can now leverage many human-like abilities in their operations using image processing and computer vision technology. One such application is Human Pose Estimation. The poses are distinguished from each other at the joints of body parts. An application of pose estimation which has attracted many researchers is exercise and one of its form with intricate postures is Yoga which is an age-old now famous worldwide because of its many spiritual, physical and mental benefits.

Pose estimation for fitness applications is particularly challenging due to the wide variety of possible poses (e.g., hundreds of yoga asanas), numerous degrees of freedom, and occlusions. The approach used here is the skeleton-based model where a set of joints (keypoints) like ankles, knees, shoulders and limb orientations of a human body are detected from an image or a video frame, which are then utilized to create a skeletal structure of the posture at any instant of time.

The RCNN model has shown the most significant results in Pose estimation problems. The input image goes through the CNN. The feature maps generated are used for the region proposal network (RPN) to generate region proposals, and used for generate feature maps for RoIAlign pooling at later part. The whole network is an end-to-end deep learning network, which is essential for gradient propagation to improve the pose detection accuracy.

Security is a mandatory feature in the field of computer vision. Adversarial attacks are one of the most famous techniques used for breaching security, which attempts to fool AI models by malicious input. For our project, we took the case of chest x-rays, since medical data is extremely fragile and minute tampering can lead to unforeseen and disastrous effects. Especially with the increase of data breaches involving medical data, it has become essential to add new types of security measures to make the models robust. In this project, initially, various types of adversarial attacking strategies are used to introduce noise into the images in the input dataset. These modified images are generally indistinguishable to the human eye, but can easily mislead the model into a completely wrong prediction. The goal is to deceive an already trained model. The defensive strategies help to make the model robust by identifying the attacks and avoid misleading predictions by the model. We implemented three different types of defense strategies against poisoning attacks to check the robustness improvement in the model.

Collaborator: Dr. George Ghinea, Brunel University, UK 

Objectives and Methodology (with schematic/ flowchart/diagram):

With the rapid developments in the industrialization and automated chemical plants, gas leakage is a common issue. Explosions, fires, spills, leaks, and waste emissions are some of the consequences of industrial accidents. Most of the gases and their fumes are colorless, odorless, and tasteless, thereby challenging our normal human senses. Sensing based on a single sensor may not be accurate, and sensor fusion is essential for robust and reliable detection in several real-world applications. The primary research question was - In a mixed gas environment, how to detect a particular gas and achieve better gas classification accuracy? 

In this work, we propose a novel approach to detect and identify the gaseous emissions using the multimodal AI fusion techniques. We manually collected 6400 gas samples (1600 samples per class for four classes) using two specific sensors: the 7-semiconductor gas sensors array, and a thermal camera. The early fusion method of multimodal AI, is applied .The network architecture (CNN+LSTM)  consists of a feature extraction module for individual modality, which is then fused using a merged layer followed by a dense layer, which provides a single output for identifying the gas. 

Contribution of this work - Develop a more reliable gas detection method involving two modalities and fusing them to achieve better results than existing methods.



Early Fusion - 

Combines features extracted from raw data which have high correlation between them, which are passed through Concatenate layer and final predictions are made.

Late Fusion - 

Decisions are taken based on the individual modalities separately. Predictions from individual modalities are then combined using statistical methods like mean, mode, median.

Objectives and Methodology: 

The exchange of goods or services between territories is known as International trade. And in many cases International trade plays a very important role in constituting the total Gross Domestic Product (GDP) of that territory. The objective of this project is to forecast the total trade of India’s trading partners in vis-à-vis trade in services. Services are the economic output of intangible commodities that may be produced, transferred, and consumed at the same time. There are many factors that influence the overall trade of a territory. An analysis on these features is required to understand how they relate to each other and the impact of such features on the overall trade of a territory.

Generative adversarial network is a technique employed in the field of Artificial Intelligence which attempts to fool models through malicious inputs. The objective is to generate malicious network traffic instances (like DDoS) looking similar to benign ones using adversarial AI which can bypass the Intrusion Detection System without creating any suspicion. 


Generative Adversarial Networks (GANs) architecture is used for this purpose. Initially, the model is trained using a random noise vector and benign network traffic instances. This way, the Generator finally learns how the non-malicious network traffic instances looks like and tries to produce the malicious traffic instances looking similar to the benign ones.

For testing and evaluation purpose, we first measure how different the output generated by the Generator is w.r.t the original benign network traffic instances. Then we pass this Generator output to the classifier (IDS) and see what the classifier’s accuracy is. One of the objectives is to keep this accuracy as low as possible.

Objectives and Methodology:

The primary objective of this project is to develop a spam filter which segregates the spam emails from the ham(non-spam) emails using Recurrent Neural Network (RNN) and domain adaptation. Every email account’s inbox today is filled with unwanted emails from various companies including promotional emails, emails from social media websites, emails containing links to unsecure websites etc. which hampers the authenticity and outreach of important emails for the user. This project aims to solve this real world problem by integrating a classic spam classifier with domain adaptation technique to achieve state-of-the-art spam filtering system. To implement this, we used SpamAssassin dataset as our source domain and our own emails dataset as target domain. Data preprocessing and text cleaning was carried out on both the datasets followed by feature extraction to convert the words to floats. We used an embedding layer followed by RNN to create the neural network for predictions. To incorporate domain adaptation, we used Domain Adversarial Neural Networks (DANN) and trained it on the labelled source dataset to achieve high accuracy on the unlabeled target dataset.

Objective / Methodology:

The rise in the usage of social media has led to escalation of contrasting ideologies and hateful speech on social media. Opinions that an individual would earlier desist from due to fear of repercussions from society have now found their way online. With most of the urban population in India being bilingual, the use of Hindi-English code mixed – Hinglish language is quite prevalent across various social media platforms. Hate speech detection algorithms deployed by most social networking platforms are unable to filter out offensive and abusive content posted in these code-mixed languages. This makes it essential to have an efficient hate speech detection algorithm which can be used to deal with such content in Indian social media space. 

The objective of this project was to detect hateful speech in Hinglish language. For this, fine tuning based approaches were applied by utilizing contextual based embeddings such as ELMo, FLAIR and transformer-based BERT. The project involved creating an annotated hate speech dataset in Hinglish, building a generic pre-processing pipeline along with development and validation of deep learning based approaches for detection of hate speech in Hinglish text.

Objective and methodology:

The main idea behind this research is to generate RL agents with distinct behaviors. This is achieved by generating next best action using generative models. The first agent is trained in environment using q-learning which produces q-values for every state action pair. 

Our GAN network is trained such that it is able to produce similar but different q-values from noise vectors. And several noise vectors in the RL environment, we can produce new agents with distinct “behaviors”, although not all the generated agents will be able follow optimal policy and perform maximum reward collection. The main objective of this work is to utilize one agent’s learning to come up with different new agents that have similar way of interacting with the environment but not the same as the first agent.


Project Title : Agricultural trade analysis between India and African countries for food security post pandemic

Mentor Name : Dr Rahee Walambe Associate Faculty, SCAAI, 

                         Associate Professor,  Dept of E&TC , SIT 

Collaborator: Dr Ishita Ghosh, SSE

Objectives and Methodology

India and African countries have a long-standing agriculture trade relationship that also ensures food security in regions of Africa. During the pandemic, many countries decided to protect their own endowments and production domestically. So they either raised trade tariffs or took to other measures of protectionism. However, given that African countries are heavily dependent on other countries for food import, protectionism is not a very practical way of approaching food security. In this work we consider this problem in the context of India and Africa. We have a manually created dataset which has various features including the economic parameters and the demographic parameters  of 13 African countries over the last decade, and our aim is to predict with which countries is trade possible leading to food security. We apply various ML methods to approach this problem. 

In one of the methods, we use multiple linear regression to first decide how and what are the factors affecting trade, and then we use the features to make predictions about the country individually. In the second method, we use the clustering algorithm to divide the countries into two clusters, one in which food security is possible and the other where it is not possible. In the third method, we use simple extrapolation to check if the value of the target variable (Export) is increasing or decreasing and based on that we can predict which countries have possibility of trade and security and which ones don’t.
