Deep Dive into the World of Data Science Through this Blog, we will read about what is data science, why it is such a buzzword these days, what makes data science such an effective and a hot technology to look forward to, what is it like to be a data scientist, what do you need to achieve to be a data scientist. You will also be made familiar about the applications, advantages, disadvantages, examples, real-life use cases, differences between machine learning and artificial intelligence vs neural networks vs deep learning vs prediction analysis. We will also be reading about the various frameworks and libraries which are in very popular demand these days such as Numpy which stands for numerical python, Pandas for data frames, Scikit learn for cross-validation techniques and other model fitting techniques, seaborn for analysis, heatmaps, Tensorflow, etc. Data science is probably the most unexplored territory today and the scope to learn and create and do something out of the box is way too much in this technology and field of sciences and mathematics.

Our modern world runs on software and data, with Git - a version control tool we track and manage the different changes and versions of our software. Git is very useful in every programmer's work. It is a must-have tool for working in any software-related field, that includes data science to machine learning. What about the data and the ML models we build? How do we track and manage them?

Purpose: Deep neural networks (DNNs) have been widely applied in medical image classification, benefiting from its powerful mapping capability among medical images. However, these existing deep learning-based methods depend on an enormous amount of carefully labeled images. Meanwhile, noise is inevitably introduced in the labeling process, degrading the performance of models. Hence, it's significant to devise robust training strategies to mitigate label noise in the medical image classification tasks. Methods: In this work, we propose a novel Bayesian statistics guided label refurbishment mechanism (BLRM) for DNNs to prevent overfitting noisy images. BLRM utilizes maximum a posteriori probability (MAP) in the Bayesian statistics and the exponentially time-weighted technique to selectively correct the labels of noisy images. The training images are purified gradually with the training epochs when BLRM is activated, further improving classification performance. Results: Comprehensive experiments on both synthetic noisy images (public OCT & Messidor datasets) and real-world noisy images (ANIMAL-10N) demonstrate that BLRM refurbishes the noisy labels selectively, curbing the adverse effects of noisy data. Also, the anti-noise BLRM integrated with DNNs are effective at different noise ratio and are independent of backbone DNN architectures. In addition, BLRM is superior to state-of-the-art comparative methods of anti-noise. Conclusions: These investigations indicate that the proposed BLRM is well capable of mitigating label noise in medical image classification tasks.

The development and deployment of "educational pathways and materials" for healthcare staff on the use of AI is the main recommendation from an NHS report. The'Understanding Healthcare Workers' Confidence in AI' report is the first of two reports to be released in light of the Topol Review in 2019 which recommended the use of digital technologies such as AI and robotics to achieve digital transformation. The report, which was developed by Health Education England and NHS AI Lab, explores the confidence healthcare workers have in AI and what could drive that to help support the further implementation of AI within the NHS. It suggests that clinicians require training and education opportunities to help manage the gap between their opinion or intuition on a patient's condition and the recommendations made by AI technology. "The main recommendation of this report is therefore to develop and deploy educational pathways and materials for healthcare professionals at all career points and in all roles, to equip the workforce to confidently evaluate, adopt and use AI," the report states.

In our case study on analyzing sentiment, you will create models that predict a class (positive/negative sentiment) from input features (text of the reviews, user profile information,...). In our second case study for this course, loan default prediction, you will tackle financial data, and predict when a loan is likely to be risky or safe for the bank. These tasks are an examples of classification, one of the most widely used areas of machine learning, with a broad array of applications, including ad targeting, spam detection, medical diagnosis and image classification. In this course, you will create classifiers that provide state-of-the-art performance on a variety of tasks. You will become familiar with the most successful techniques, which are most widely used in practice, including logistic regression, decision trees and boosting.

Alexa Joyce, future skills director at Microsoft, discusses how the education sector can go about unlocking its'black box' of data As the UK education system recovers from the effects of the global pandemic, there has been a significant rise in attention paid to the increased use of technology in teaching and learning. Two billion learners will use digital learning services by 2050, while the education technology (edtech) market is projected to triple by 2025, with global spending reaching $404bn. As investment in edtech continues to grow, students, parents, and teachers face an array of solutions -- from digital personalised learning platforms, devices and accessories, through to multiple online courses. Alongside the opportunities technology provides for increasing accessibility, the wealth of data that edtech offers is unsurmountable. But, how can technology allow policymakers, school leaders and sector experts to unlock this'black box' of education data and use it for improved learning outcomes?
