Title: RSNA Pneumonia Detection Challenge

Description:

Our team’s project is the RSNA Pneumonia Detection Challenge from Kaggle competition. The primary goal of this project is to develop a machine learning tool to detect patients with pneumonia based on their chest radiographs (CXR).

Pneumonia is an infection that inflames the air sacs in human lungs which has symptoms such as chest pain, cough, and fever [1]. Pneumonia can be very dangerous especially to infants and elders. In 2015, 920,000 children under the age of 5 died from this disease [2]. Due to its fatality to children, diagnosing pneumonia has a high order. A common method of diagnosing pneumonia is to obtain patients’ chest radiograph (CXR) which is a gray-scale scan image of patients’ chests using x-ray. The infected region due to pneumonia usually shows as an area or areas of increased opacity [3] on CXR. However, many other factors can also contribute to increase in opacity on CXR which makes the diagnose very challenging. The diagnose also requires highly-skilled clinicians and a lot of time of CXR screening. The Radiological Society of North America (RSNA®) sees the opportunity of using machine learning to potentially accelerate the initial CXR screening process.

For the scope of this project, our team plans to contribute to solving this problem by applying our machine learning knowledge in image processing and classification. Team members are going to apply techniques that include, but are not limited to: logistic regression, random forest, SVM, kNN, CNN, etc., in order to successfully detect CXRs with pneumonia.

Title: Kaggle Challenge: Quick, Draw! Doodle Recognition Challenge

Description:

Our team chose the Quick, Draw! Doodle Recognition Challenge from the Kaggle Competition. The goal of the competition is to build an image recognition tool that can classify hand-drawn doodles into one of the 340 categories.

The main challenge of the project remains in the training set being very noisy. Hand-drawn artwork may deviate substantially from the actual object, and is almost definitively different from person to person. Mislabeled images also present a problem since they will create outlier points when we train our models.

We plan on learning more about some of the currently mature image recognition algorithms to inspire and develop our own model.

Title: Reproducibility report: *Fixing Variational Bayes: Deterministic Variational Inference for Bayesian Neural Networks*

Description:

The paper *Fixing Variational Bayes: Deterministic Variational Inference for Bayesian Neural Networks* [1] has been submitted to ICLR 2019. It aims to "fix" variational Bayes and turn it into a robust inference tool through two innovations.

Goals are to:

- reproduce the deterministic variational inference scheme as described in the paper without referencing the original author's code, providing a 3rd party implementation

- reproduce experiment results with own implementation, using the same NN framework for reference implementations of compared methods described in the paper

- reproduce experiment results with the author's own implementation

- explore other possible applications of variational Bayes besides heteroscedastic regression

Title: Kaggle Challenge: Quick, Draw! Doodle Recognition Challenge

Description:

Classification has become a more and more eye-catching, especially with the rise of machine learning in these years. Our team is particularly interested in machine learning algorithms that optimize some specific type image classification.

In this project, we will dig into base classifiers we learnt from the class and try to cook them together to find an optimal solution for a certain type images dataset. Currently, we are looking into a dataset from Kaggle: Quick, Draw! Doodle Recognition Challenge. The dataset in this competition contains 50M drawings among 340 categories and is the subset of the world’s largest doodling dataset and the doodling dataset is updating by real drawing game players. Anyone can contribution by joining it! (quickdraw.withgoogle.com).

For us, as machine learning students, we are more eager to help getting a better classification method. By “better”, we mean find a balance between simplify and accuracy. We will start with neural network via different activation functions in each layer and we will also combine base classifiers with bagging, random forest, boosting for ensemble learning. Also, we will try to regulate our parameters to avoid overfitting in training dataset. Last, we will summary features of this type image dataset, formulate our solutions and standardize our steps to solve this kind problems

Hopefully, we can not only finish our project successfully, but also make a little contribution to machine learning research field.

Title: Kaggle Challenge: Human Protein Atlas Image Classification

Description:

We will participate in the Human Protein Atlas Image Classification competition featured on Kaggle. We will classify proteins based on patterns seen in microscopic images of human cells.

Historically, the work done to classify proteins had only developed methods to classify proteins using single patterns of very few cell types at a time. The goal of this challenge is to develop methods to classify proteins based on multiple/mixed patterns and with a larger range of cell types.

Title: Quick, Draw! Doodle Recognition

Description:

Background

Google’s Quick, Draw! is an online game where a user is prompted to draw an image depicting a certain category in under 20 seconds. As the drawing is being completed, the game uses a model which attempts to correctly identify the image being drawn. With the aim to improve the underlying pattern recognition model this game uses, Google is hosting a Kaggle competition asking the public to build a model to correctly identify a given drawing. The model should classify the drawing into one of the 340 label categories within the Quick, Draw! Game in 3 guesses or less.

Proposed Approach

Each image/doodle (input) is considered as a matrix of pixel values. In order to classify images, we need to essentially reshape an images’ respective matrix of pixel values - convolution. This would reduce the dimensionality of the input significantly which in turn reduces the number of parameters of any proposed recognition model. Using filters, pooling layers and further convolution, a final layer called the fully connected layer is used to correlate images with categories, assigning probabilities (weights) and hence classifying images.

This approach to image classification is called convolution neural network (CNN) and we propose using this to classify the doodles within the Quick, Draw! Dataset.

To control overfitting and underfitting of our proposed model and minimizing the error, we will use different architectures consisting of different types and dimensions of pooling layers and input filters.

Challenges

This project presents a number of interesting challenges:

  • The data given for training is noisy in that it contains drawings that are incomplete or simply poorly drawn. Dealing with this noise will be a significant part of our work.
  • There are 340 label categories within the Quick, Draw! dataset, this means that the model created must be able to classify drawings based on a large pool of information while making effective use of powerful computational resources.

Title: Expanding Neural Netwrok

Description: The goal of our project is to create an expanding neural network algorithm which starts off by training a small neural network then expands it to a larger one. We hypothesize that with the proper expansion method we could decrease training time and prevent overfitting. The method we wish to explore is to link together input dimensions based on covariance. Then when the neural network reaches convergence we create a larger neural network without the links between dimensions and using starting values from the smaller neural network.

Title: Application of ML Classification to Cancer Identification

Description: The application of machine learning to cancer classification based on gene expression is a topic of great interest to physicians and biostatisticians alike. We would like to work on this for our final project to encourage the application of proven ML techniques to improve accuracy of cancer classification and diagnosis. In this project, we will use the dataset from Golub et al. [1] which contains data on gene expression on tumour biopsies to train a model and classify healthy individuals and individuals who have cancer.

One challenge we may face pertains to the way that the data was collected. Some parts of the dataset have thousands of features (which each represent a quantitative measure of the expression of a certain gene) but as few as twenty samples. We propose some ways to mitigate the impact of this; including the use of PCA, leave-one-out cross validation, or regularization.

Title: Google Analytics Customer Revenue Prediction [1] - A Kaggle Competition

Description: Guess which cabin class in airlines is the most profitable? One might guess economy - but in reality, it's the premium classes that show higher returns. According to research conducted by Wendover productions [2], despite having less than 50 seats and taking up more space than the economy class, premium classes end up driving more revenue than other classes.

In fact, just like airlines, many companies adopt the business model where the vast majority of revenue is derived from a minority group of customers. As a result, data-intensive promotional strategies are getting more and more attention nowadays from marketing teams to further improve company returns.

In this Kaggle competition, we are challenged to analyze a Google Merchanidize Store's customer dataset to predict revenue per customer. We will implement a series of data analytics methods including pre-processing, data augmentation, and parameter tuning. Different classification algorithms will be compared and optimized in order to achieve the best results.

Our team currently has two interested topics at hand, and we have summarized the objective of each topic below. Please note that we will narrow down our choices after further discussions with the instructor.

Description 1: With 14 percent of American claiming that social media is their most dominant news source, fake news shared on Facebook and Twitter are invading people’s information learning experience. Concomitantly, the quality and nature of online news have been gradually diluted by fake news that are sometimes imperceptible. With an aim of creating an unalloyed Internet surfing experience, we sought to develop a tool that performs fake news detection and classification.

Description 2: Statistics Canada has recently reported an increasing trend of Toronto’s violent crime score. Though the Royal Canadian Mounted Police has put in the effort and endeavor to track crimes, the ambiguous snapshots captured by outdated cameras often hamper the investigation. Motivated by the aforementioned circumstance, our second interest focuses on the accurate numeral and letter identification within variable-resolution images.

Title: Kaggle--Two Sigma: Using News to Predict Stock Movements

Description: The movement in price of a trade-able security, or stock, on any given day is an aggregation of each individual market participant’s appraisal of the intrinsic value of the underlying company or assets. These values are primarily driven by investors’ expectations of the company’s ability to generate future free cash flow. A steady stream of information on the state of macro and micro-economic variables which affect a company’s operations inform these market actors, primarily through news articles and alerts. We would like to take a universe of news headlines and parse the information into features, which allow us to classify the direction and ‘intensity’ of a stock’s price move, in any given day. Strategies may include various classification methods to determine the most effective solution.
