MEHDY, M. M., P. Y. NG,  E. F. SHAIR, N. I. SALEH, CHANDIMA GOMES.2017. Artificial neural networks in image processing for early detection of breast cancer. Computational and mathematical methods in medicine.

The paper examines four different approaches to breast cancer in medicine ( MRI, IR< Mammography and ultrasound). For the classification, the paper looks at three different techniques: Support Vector Machine, Method based on rule ( decision tree and rough sets), Artificial Neural Network. The paper also divided the types of data that need to be classified: calcification and non calcification, benign and malignant, dense and normal breast, tumorous and non tumorous. The paper addressed different types of Neural networks that exist and have been used in related works in Breast Cancer Detection : Feed-forward backpropagation, Convolution Neural Networks.

NOTES:

• The paper looks/reviews into four different applications of medical imaging: MRI, IR, mammography and ultrasound for the cause of identifying breast cancer early
• It addresses the use of hybrid Neural Networks in breast cancer detection
• Investigates artificial neural networks  in the processing of images
• Reviews three types of classification decisions for image feature selection and focuses on one (ANN- artificial neural network):Support Vector Machine, method based on rule ( decision tree and rough sets), artificial neural network
• Subtle appearances and ambiguous margins are the obstacles for differentiating abnormalities if present in breast cancer using mammogram
• Artificial Neural network is used in CAD(computer-aided diagnosis) allowing to overcome difficulties of image processing by radiologists. ANN has two applications in CAD: direct application of classifier at the image data region of interest (ROI) and using preprocessed image signals analyzing the extracted features of an image
• Look into Dhawan et al.: used 3-layer neural network and backpropagation algorithm for image structure feature identification
• Image processing includes various techniques and one of them is the image segmentation. It detects small, local and bright spots on a raw image. 
• Image segmentation reaches high accuracy by relying on a set of labeled test images( true positives(TP), false positives(FP)).
• The technique used in this paper for pattern classification is called on cascade correlation (CC) 
• Look into: Sinin and Vijai – Grey-Level Co Occurrence Matrix(GLCM)
• Ultrasound – creating three-dimensional ultrasound imaging giving in debt information on breast lesion 
• MRI imaging  – recommended way of soft tissue recognition. 
• The types of data that is needed to classify in this paper is of these types: calcification and non calcification, benign and malignant, dense and normal breast, tumorous and non tumorous. 

Breast Cancer detection using deep convolutional neural networks and support vector machines

RAGAB, DINA A., MAHA SHARKAS, STEPHEN MARSHALL, JINCHANG REN.2019.Breast cancer detection using deep convolutional neural networks and support vector machines. PeerJ ,7(e6201).

This paper, for breast cancer detection, is using CAD (Computer Aided Detection) classifier to differentiate benign and malignant mass tumors in breast mammography.  It touches upon two techniques used in CAD – manual determination of the region of interest and technique of threshold based on the region. For the feature extract, the paper is using DCNN (Deep Convolutional Neural Network), allowing accuracy of 71.01%. Look up AlexNet for more reference and background on DCNN. Another classifier that the paper explores includes  Support Vector Machine(which appears to be very useful in fake news detection as well and is very common in cancer detection techniques). This paper, in contrast to other papers in this field, focuses on getting a better image segmentation by increasing the contrast, suppressing noise to reach higher accuracy of breast cancer detection.  Look up other image enhancement techniques that are referenced in this paper (E.g. Adaptive COntrast Enhancement, Contrast-limited Adaptive Histogram Equalization). 

NOTES:

• Uses CAD (computer aided detection system to classify benign and malignant mass tumors in breast mammography images

• The types of neural network that this paper is looking at is DCNN – deep convolutional neural network to extract features.
• Look AlexNet for DCNN 
• Touches upon support vector machine (SVM) classifier for higher accuracy
• Using datasets: (1) the digital database for screening mammography (DDSM); and (2) the Curated Breast Imaging Subset of DDSM (CBIS-DDSM)
• Uses data augmentation to get bigger input data taht is based on the original data – uses rotation type of data augmentation
• The accuracy of this approach DCNN is 71.01%
• The process of CAD systems consists of  steps: image enhancement, image segmentation, feature extraction, feature classification, evaluation for the classifier
• This paper, in contrast to the one previously mentioned, touches upon getting a better image for segmentation – it enhances images by increasing the contrast, suppressing noise for a better and accurate breast cancer determination
• Look these image enhancement techniques: adaptive contrast enhancement, contrast -limited adaptive histogram equalization – type of an AHE used to improve the contrast in images
• There are few methods for image segmentation that the author review: edge, fuzzy theory, partial differential equation, artificial neural network, threshold and region-based segmentation

ASWATHY, M. A., M. JAGANNATH. 2017.Detection of breast cancer on digital histopathology images: Present status and future possibilities. Informatics in Medicine Unlocked, 8 : 74-79.

For the breast cancer detection idea, this paper references Spanhol et al. as the source of the data (over 7000 images) used in the training of the algorithm. The steps of the image processing from histopathology are: preprocessing of the images, then segmentation, extraction of the feature and classification. The paper is reviewing convolutional neural networks as an image processing method. Compared to the previous paper, this paper is focusing on the importance of biopsy methods of cancer detection as well as reviews other methods that are common in cancer detection. For future development, the paper is suggesting to explore spectral imaging as well as create more powerful tools to achieve higher image resolution.

Notes:

Beyond News Contents: the role of Social Context for Fake News Detection 

SHU, KAI, SUHANG WANG, AND HUAN LIU.2019. Beyond news contents: The role of social context for fake news detection. In Proceedings of the Twelfth ACM International Conference on Web Search and Data Mining, 312-320.

This paper proposes a tri-relationship framework for fake news detection that analyzes publisher-news relations as well as user-news interactions. The algorithm behind news content embedding is based on nonnegative matrix factorization that projects the news-word matrix to the semantics factor. The evaluation of reported performance is the average of three training processes of TriFN (tri-relationship framework) performances. This paper, in addition, also checks if there is an existing relationship between the delay time of the news and detection of fake news. It also analyzes the importance of social engagement on the performance of fake news detection.

NOTES: 

• Proposes Tri-relationship framerfork (TriFN) – for publisher-news relations modeling and user-news interactions 
• Uses nonnegative matrix factorization algorithm for projecting news-word matrix to the semantics factor space ( NEWS CONTENTS EMBEDDING)
• Evaluates the performance of TriFn by generating the training process three times and the average performance is reported.
• The paper also checks what’s the correlation between the delay time and detection performance  – social engagement as a helping factor for fake news detection
• Related works : references to previous work that has been done in linguistic -based and visual-based

1. Fake news/unreliable source detection

Fake news detection algorithm would be an improved version of detecting unreliable sources. For this, I would need to come up with a database of credible data and identify the trustworthiness of the source based on that database. 

Combination of multiple features will be required to identify to then evaluate the unreliability of the news/source. Some of those features are word combination, attached images, clickbait analysis, and checking whether the content is sponsored.

Machine learning would be used to create this algorithm ( some similar projects identified hybrid approaches that used user characteristics from a particular social media as well as the user’s social graph. The algorithm was based on node2vec that allowed extraction from social media followers/followers. )

My project would allow a user interface for interaction and manual news/source credibility check. This project would be unique with the accuracy of the source reliability and work on more than one medium. 

2. Breast cancer detection

Various ways of cancer detection have been detected in recent years as technology and medicine start moving more hand in hand. Depending on the type of cancer, there are different ways of detecting cancer in medicine. For breast cancer, the most common methods of detecting are through MRI, breast ultrasound, mammograms. 

 Is there a way to get the hints of cancer early, before it has developed into its late stages?

 I will be looking at previous work that has been done in integrating the medical records ( images from the methods mentioned above) into an algorithm of image processing and cancer detection. 

I will be using image processing (from MRI, breast ultrasound, mammogram) to explore the historiography method. I will be looking at thermal body scan results as well and comparing these two approaches. For this, I will also explore the work done previously in this field.

I have searched and found various datasets present on Kaggle on mammogram scans.

3. Crime prediction/prevention

This project involves past crime analysis in a particular city (e.g., Boston or Indianapolis), takes the types of crime that happened in one of these locations, and uses machine learning neural networks to predict the possible crime location/hotspot. This project would rely on data mining through the records of crime. 

This algorithm would also consider other features such as economic changes, news, and their impact on the crime rate. I consider taking into account the level of the crime and putting this into the analysis.
