For our project, we intend to replicate and hopefully, extend the work of Romdhane et al.’s 2020 paper “Electrocardiogram heartbeat classification based on a deep convolutional neural network and focal loss”. In this paper, the authors develop a deep convoluted neural network that exploits a novel loss function, focal loss, to classify heartbeats into five arrhythmia categories (N, S, V, Q and F) based on the AAMI standard. The network was trained and tested against two ECG datasets, MIT-BIH and INCART, and returned a 98.41% overall accuracy, a 98.38% overall F1-score, a 98.37% overall prevision and a 98.41% overall recall, which we intend to replicate.

Interestingly, focal loss was implemented to prevent bias towards larger classes (normal heart beats) without needing to augment the smaller class data (diseased heart beats), however the authors did not outline which method actually performs better. Therefore, we hope to extend their work by answering this question in this project.

Title: APTOS 2019 Blindness Detection

Description:

Our team chose the APTOS 2019 Blindness Detection Challenge from Kaggle. The goal of this challenge is to build a machine learning model that detects diabetic retinopathy by screening retina images.

Millions of people suffer from diabetic retinopathy, the leading cause of blindness among working-aged adults. It is caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). In rural areas where medical screening is difficult to conduct, it is challenging to detect the disease efficiently. Aravind Eye Hospital hopes to utilize machine learning techniques to gain the ability to automatically screen images for disease and provide information on how severe the condition may be.

Our team plans to solve this problem by applying our knowledge in image processing and classification.

Title: Risk prediction in life insurance industry using supervised learning algorithms

Description:

In this project, we aim to replicate and possibly improve upon the work of Jayabalan et al. in their paper “Risk prediction in life insurance industry using supervised learning algorithms”. We will be using the Prudential Life Insurance Data Set that the authors have used and have shared with us. We will be pre-processing the data to replace missing values, using feature selection using CFS and feature reduction using PCA use this processed data to perform Classification via four algorithms – Neural Networks, Random Tree, REPTree and Multiple Linear Regression. We will compare the performance of these Algorithms using MAE and RMSE metrics and come up with visualizations that can explain the results easily even to a non-quantitative audience.

Our goal behind this project is to learn applying the algorithms that we learned in our class to an industry dataset and come up with results that we can aid better, data-driven decision making.

Title: Lyft Motion Prediction for Autonomous Vehicles

Description:

Our team has decided to participate in the Lyft Motion Prediction for Autonomous Vehicles Kaggle competition. The aim of this competition is to build a model which given a set of objects on the road (pedestrians, other cars, etc), predict the future movement of these objects.

Autonomous vehicles (AVs) are expected to dramatically redefine the future of transportation. However, there are still significant engineering challenges to be solved before one can fully realize the benefits of self-driving cars. One such challenge is building models that reliably predict the movement of traffic agents around the AV, such as cars, cyclists, and pedestrians.

Our aim is to apply classification techniques learned in class to optimally predict how these objects move.

Title: Classification with Abstinence

Description:

We seek to implement the algorithm described in Deep Gamblers: Learning to Abstain with Portfolio Theory. The paper describes augmenting classification problems to include the option of abstaining from making a prediction when confidence is low.

Medical imaging diagnostics is a field in which classification could assist professionals and improve life expectancy for patients through increased accuracy. However, there are also severe consequences to incorrect predictions. As such, we also hope to apply the algorithm implemented to the classification of medical images, specifically instances of normal and pneumonia chest x-rays.

Title: Combine Convolution with Recurrent Networks for Text Classification

Description:

Our team chose to reproduce the paper Combine Convolution with Recurrent Networks for Text Classification on Arxiv. The goal of this paper is to combine CNN and RNN architectures in a way that more flexibly combines the output of both architectures other than simple concatenation through the use of a “neural tensor layer” for the purpose of improving at the task of text classification. In particular, the paper claims that their novel architecture excels at the following types of text classification: sentiment analysis, news categorization, and topical classification. Our team plans to recreate this paper by working in pairs of 2, one pair to implement the CNN pipeline and the other pair to implement the RNN pipeline. We will be working with Tensorflow 2, Google Collab, and reproducing the paper’s experimental results with training on the same 6 publicly available datasets found in the paper.

Title: Application of classification in human fatigue analysis

Description:

The goal of this project is to classify different levels of fatigue based on motion capture (Vicon) and force plates data. First, we plan to obtain data from 4 to 6 participants performing squats or squats with weights and rate them on a fatigue scale, with each participant doing at least 50 to 100 reps. We will collect data with EMG, IMU, force plates, and Vicon. When the participants are squatting, we will ask them about their fatigue level, and compare their feedback against the fatigue level recorded on EMG. The fatigue level will be on a scale of 1 to 10 (1 being not fatigued at all and 10 being cannot continue anymore). Once data is collected, we will classify the motion capture and force plates data into the different levels of fatigue.

Title: Identification (Classification) of Submillimetre Galaxies Based on Multiwavelength Data in Astronomy

Description:

Identifying the counterparts of submillimetre galaxies (SMGs) in multiwavelength images is important to the study of galaxy evolution in astronomy. However, obtaining a statistically significant sample of robust associations is very challenging because of the poor angular resolution of single-dish submm facilities, that is we can not tell which galalxy is actually responsible for the submillimeter emission from a group of possible candidates due to the poor resolution. Recently, a set of labelled dataset is obtained from ALMA, a milliemetre/submilliemetre telescope array with the sufficient resolution to pin down the exact source of submillimeter emssion. However, applying such array to large fraction of skies are not feasible, so it is of practical interest to develop algorithm to identify submillimetre galaxies (SMGs) based on the other available data. With this newly labelled dataset from ALMA, it is possible to test and develop different new alrgorithms and apply them on unlabelled data to detect submillimetre galaxies.

In our work, we primarily build on the works of Liu et al.(https://arxiv.org/abs/1901.09594), which tested a set of standard classification algorithms to the dataset. We aim to first reproduce their work and test other classification algorithms with a more stastics centered perspective. Next, we hope to possibly extend their works from one or some of the following directions: (1)Incorporating some other relevant features to augment the dimensions of the available dataset for better classification rate. (2)Taking the measurement error into the classifcation algorithms, possibly from a Bayesian approach. (All features in astronomy datasets come from actual physical measurements, which come with an error bar. However, it is not clear how to incoporate this error into the classification task.) (3)The possibility of combining some tradtional astronomy approaches with algorithms from ML.

Title: Insider Trading Roles Classification Prediction on United States conventional stock or non-derivative transaction

Description:

Background (why we were interested in classifying based on insiders): The United States is one of the most frequently traded financial markets in the world. The dataset captures all insider activities as reported on SEC (U.S. Securities and Exchange Commission) forms 3, 4, 5, and 144. We believe that using variables (such as transaction date, security type, and transaction amount), we could predict the roles code for a new transaction. The reason for the chosen prediction is that the role of the insider gives investors signals of potential internal activities and private information. This is crucial for investors to detect important market signals from those insider trading activities, such that they could benefit from the market.

Goal: To classify the role of an insider in a company based on the data of their trades.

Title: Mechanisms of Action (MoA) Prediction

Description:

The final project of our team is the Kaggle ongoing competition -- Mechanism of Action(MoA) Prediction. The goal is to improve the MoA prediction algorithm to assist and advance drug development. MoA algorithm helps scientists approach more targeted medicine molecules based on the biological mechanism of disease. This would strongly shorten the medicine development cycle. Here, MoA here is to apply different drugs to human cells to analyze the corresponding reaction and the dataset provides simultaneous measurement of 100 types of human cells and 5000 drugs.

To tackle this competition, after data cleaning and feature engineering, we are going to try a selection of ML algorithms such as logistic regression, tree-based method, SVM, etc and find the optimized one that can best complete the tasks. Depending on how we perform, we might utilize other technics such as model ensembling or stacking.

Title: Mechanisms of Action (MoA) Prediction (https://www.kaggle.com/c/lish-moa/overview/description)

Description:

For our final project, we will be competing in the Mechanisms of Action (MoA) Prediction Research Challenge on Kaggle. MoA refers to the description of the biological activity of a given molecule and scientists have specific interest in the MoA of molecules as it pertains to the advancement of drugs. This is because under new frameworks, scientists are looking to develop molecules that can modulate protein targets associated with given diseases. Our task will be to analyze a dataset containing human cellular responses to more than 5, 000 drugs and to classify these responses with one or more MoA.

For this competition, we plan to use various classification algorithms taught in STAT 441 followed by model validation techniques to ultimately select the most accurate model based on the logarithmic loss function which was specified by Kaggle.

Title: Classifying SARS-CoV-2 region of origin based on DNA/RNA sequence

Description:

Determining the location of origin for a viral sequence is an important tool for epidemiological tracking. Knowing where a virus comes from allows epidemiologists to track how a virus is spreading. There are significant efforts to track the spread of SARS-CoV-2. As an RNA virus, SARS-CoV-2 mutates frequently. Most of these mutations carry negligible changes to the function of the virus but act as “barcodes” for specific strains. As the virus spreads in a region, it picks up mutations which allow researchers to identify which sequences correspond to which regions.

The standard method for classifying viruses based on location is to:

- Perform a multiple sequence alignment (MSA)

- Build a phylogenetic tree of the MSA

- Empirically determine which regions have which sections of the tree

Phylogenetic trees are an excellent tool for tracking evolutionary changes over time but we wonder if there are better methods for classifying the region of origin for a virus using machine learning techniques.

Our plan is to perform PCA on the MSA which is available through GISAID. We will determine an appropriate encoding for sequence alignments to vectors and map the aligned sequences onto a much lower dimensional space. We will then use LDA or QDA to classify points based on region (continent). We will also examine if the same technique works well for classifying sequences based on state of origin for samples from the United States. We may try other classification techniques such as logistic regression or neural nets. Finally, we know that projecting data to a small number of principal components and then projecting back to the original space can reduce noise in certain datasets. In the case of mutations, this might correspond to removing insignificant mutations. It is possible that there are certain mutations which induce functional changes in the virus which would be of greater medical interest. Our hope is that we could detect these using PCA.

Title: Lyft Motion Prediction for Autonomous Vehicles

Description:

We are planning to compete in the Lyft Motion Prediction for Autonomous Vehicles Challenge on Kaggle. Our goal is to build a motion prediction model for the self-driving car by using our machine learning knowledge as well as utilizing the training and testing data sets. The motion prediction model will predict the motion of traffic agents around the car, such as cars, cyclists, and pedestrians. We are not sure if we have to classify the agents into three categories (cars, cyclists, pedestrians) ourselves. If so, we will initially start by using the single-shot detector algorithm and improve through it.

Title: Reproducing result in Accelerated Stochastic Power Iteration

Description:

As our final project, we will reproduce the stochastic PCA algorithm designed by De Sa, He, Mitliagkas, Ré, and Xu to accelerate the iteration complexity for power iteration. By doing so, we are aiming to achieve a final rate of 𝒪(1/sqrt(Δ)) for our reproduction result. We are also hoping to explore and discuss the potentiality for applying such an acceleration method to other non-convex optimization problems, as mentioned in the original paper if there is additional time to do so.

Title: Replicating "Electrocardiogram heartbeat classification based on a deep convolutional neural network and focal loss"

Description:

For our project, we intend to replicate and hopefully, extend the work of Romdhane et al.’s 2020 paper “Electrocardiogram heartbeat classification based on a deep convolutional neural network and focal loss”. In this paper, the authors develop a deep convoluted neural network that exploits a novel loss function, focal loss, to classify heartbeats into five arrhythmia categories (N, S, V, Q and F) based on the AAMI standard. The network was trained and tested against two ECG datasets, MIT-BIH and INCART, and returned a 98.41% overall accuracy, a 98.38% overall F1-score, a 98.37% overall prevision and a 98.41% overall recall, which we intend to replicate. Interestingly, focal loss was implemented to prevent bias towards larger classes (normal heart beats) without needing to augment the smaller class data (diseased heart beats), however the authors did not outline which method actually performs better. Therefore, we hope to extend their work by answering this question in this project.
