Principles of Good Visualization

The following are the principles of good visualization by Andy Kirk: Good data visualization is trustworthy: Truthfulness and accuracy should be an obligation. Trustworthiness is about being transparent giving readers all the information they need in order to feel confident about what they are reading and what interpretations are legitimate. Good data visualization is accessible: […]

360 Degree View

360 Degree View is not only for analytics that gives insights into customer behaviour. It also provides guidance on how to engage, develop trusted relationships, solve customer problems and eventually upsell or cross-sell by enabling to zero in on what a particular customer needs and not spend time searching for information. 360 Degree View is […]

Classification of Alzheimer’s Disease Stages using Radiology Imaging and Longitudinal Clinical Data – Part 10

Discussion The project has fully answered research questions after implementing different machine learning techniques and evaluating the performance of the models. The developed model and user-friendly web application contribute to supporting an end-to-end pipeline to predict the stages of Alzheimer’s disease. This is a continuation from here. Further, the practical application, use of libraries, software […]

Classification of Alzheimer’s Disease Stages using Radiology Imaging and Longitudinal Clinical Data – Part 9

Use Feature Selection Techniques and Build an Ensemble of Classification Models Feature selection is an automatic or manual process to select features which contribute to the prediction and remove irrelevant features that negatively impact the performance of the model. It helps to reduce overfitting and training time while improving performance. It is also an important […]

Classification of Alzheimer’s Disease Stages using Radiology Imaging and Longitudinal Clinical Data – Part 8

Fine Tuning of an Ensemble of Classification Models Using Random Grid Search Parameters for a model are learned during the training while hyperparameters are set to control the implementation of the model. Grid-search is a technique used to find the optimal hyperparameters for a model. Ensemble learning involves training multiple models and combining the diverse […]
