At the end of each week, you'll reflect on your learning and plot. Next steps to apply what you've learned in your professional practice. This is an important part of the course that we hope you'll use as a roadmap to better manage your team's data science projects. Now let's talk about what this course is all about. The aim of the course is to equip executives with the knowledge that will enable them to work productively with data scientists.
A Short and Direct Walk with Pascal's Triangle
Classic pathfinding algorithms like Dijkstra's Algorithm and A* are used to generate travel routes in applications such as video games, mobile robotics, and architectural design. Despite the popularity of these algorithms, the paths they produce rarely go straight. In this article, you'll learn how to compute highly direct paths using a counting technique inspired by Pascal's Triangle. It's an idea my colleagues and I developed and recently published in the Journal of Artificial Intelligence Research [1]. With the simple step of counting paths, you can overcome a long-standing problem with traditional pathfinding.
Benefits of Unsupervised Machine Learning Courses in India
Another advantage of unsupervised learning is that the candidates can complete the entire course on their own in India. There is no teacher supervision involved. However, the downside is that no assistance is provided by the instructor in case of an accident during training. If the candidate has any query regarding anything then they should directly ask their instructor. For those who are interested in doing unsupervised machine learning courses in India, they need to do a little research in this field.

Online Regularized Learning Algorithm for Functional Data
In recent years, functional linear models have attracted growing attention in statistics and machine learning, with the aim of recovering the slope function or its functional predictor. This paper considers online regularized learning algorithm for functional linear models in reproducing kernel Hilbert spaces. Convergence analysis of excess prediction error and estimation error are provided with polynomially decaying step-size and constant step-size, respectively. Fast convergence rates can be derived via a capacity dependent analysis. By introducing an explicit regularization term, we uplift the saturation boundary of unregularized online learning algorithms when the step-size decays polynomially, and establish fast convergence rates of estimation error without capacity assumption. However, it remains an open problem to obtain capacity independent convergence rates for the estimation error of the unregularized online learning algorithm with decaying step-size. It also shows that convergence rates of both prediction error and estimation error with constant step-size are competitive with those in the literature.
Question-type Identification for Academic Questions in Online Learning Platform
Rabiee, Azam, Goel, Alok, D'Souza, Johnson, Khanwalkar, Saurabh
Online learning platforms provide learning materials and answers to students' academic questions by experts, peers, or systems. This paper explores question-type identification as a step in content understanding for an online learning platform. The aim of the question-type identifier is to categorize question types based on their structure and complexity, using the question text, subject, and structural features. We have defined twelve question-type classes, including Multiple-Choice Question (MCQ), essay, and others. We have compiled an internal dataset of students' questions and used a combination of weak-supervision techniques and manual annotation. We then trained a BERT-based ensemble model on this dataset and evaluated this model on a separate human-labeled test set. Our experiments yielded an F1-score of 0.94 for MCQ binary classification and promising results for 12-class multilabel classification. We deployed the model in our online learning platform as a crucial enabler for content understanding to enhance the student learning experience.
End-to-End Stochastic Optimization with Energy-Based Model
Kong, Lingkai, Cui, Jiaming, Zhuang, Yuchen, Feng, Rui, Prakash, B. Aditya, Zhang, Chao
Decision-focused learning (DFL) was recently proposed for stochastic optimization problems that involve unknown parameters. By integrating predictive modeling with an implicitly differentiable optimization layer, DFL has shown superior performance to the standard two-stage predict-then-optimize pipeline. However, most existing DFL methods are only applicable to convex problems or a subset of nonconvex problems that can be easily relaxed to convex ones. Further, they can be inefficient in training due to the requirement of solving and differentiating through the optimization problem in every training iteration. We propose SO-EBM, a general and efficient DFL method for stochastic optimization using energy-based models. Instead of relying on KKT conditions to induce an implicit optimization layer, SO-EBM explicitly parameterizes the original optimization problem using a differentiable optimization layer based on energy functions. To better approximate the optimization landscape, we propose a coupled training objective that uses a maximum likelihood loss to capture the optimum location and a distribution-based regularizer to capture the overall energy landscape. Finally, we propose an efficient training procedure for SO-EBM with a self-normalized importance sampler based on a Gaussian mixture proposal. We evaluate SO-EBM in three applications: power scheduling, COVID-19 resource allocation, and non-convex adversarial security game, demonstrating the effectiveness and efficiency of SO-EBM.

Machine Learning For Data Science Using MATLAB
MATLAB is a widely used programming language for statistical computing. This course is for you if you want to have a real feel of the Machine Learning techniques without having to learn all the complicated maths. Additionally, this course is also for you if you have had previous hours and hours of machine learning theory but could never got a change or figure out how to implement and solve data science problems with it. The approach in this course is very practical and we will start everything from very scratch. We will immediately start coding after a couple of introductory tutorials and we try to keep the theory to bare minimal.
