ASE: Anomaly Scoring Based Ensemble Learning for Imbalanced Datasets
Liang, Xiayu, Gao, Ying, Xu, Shanrong
Nowadays, many classification algorithms have been applied to various industries to help them work out their problems met in real-life scenarios. However, in many binary classification tasks, samples in the minority class only make up a small part of all instances, which leads to the datasets we get usually suffer from high imbalance ratio. Existing models sometimes treat minority classes as noise or ignore them as outliers encountering data skewing. In order to solve this problem, we propose a bagging ensemble learning framework $ASE$ (Anomaly Scoring Based Ensemble Learning). This framework has a scoring system based on anomaly detection algorithms which can guide the resampling strategy by divided samples in the majority class into subspaces. Then specific number of instances will be under-sampled from each subspace to construct subsets by combining with the minority class. And we calculate the weights of base classifiers trained by the subsets according to the classification result of the anomaly detection model and the statistics of the subspaces. Experiments have been conducted which show that our ensemble learning model can dramatically improve the performance of base classifiers and is more efficient than other existing methods under a wide range of imbalance ratio, data scale and data dimension. $ASE$ can be combined with various classifiers and every part of our framework has been proved to be reasonable and necessary.

The AI Chatbot Handbook โ How to Build an AI Chatbot with Redis, Python, and GPT
In order to build a working full-stack application, there are so many moving parts to think about. And you'll need to make many decisions that will be critical to the success of your app. For example, what language will you use and what platform will you deploy on? Are you going to deploy a containerised software on a server, or make use of serverless functions to handle the backend? Do you plan to use third-party APIs to handle complex parts of your application, like authentication or payments? Where do you store the data? In addition to all this, you'll also need to think about the user interface, design and usability of your application, and much more. This is why complex large applications require a multifunctional development team collaborating to build the app. One of the best ways to learn how to develop full stack applications is to build projects that cover the end-to-end development process. You'll go through designing the architecture, developing the API services, developing the user interface, and finally deploying your application. So this tutorial will take you through the process of building an AI chatbot to help you learn these concepts in depth. Important Note: This is an intermediate full stack software development project that requires some basic Python and JavaScript knowledge. I've carefully divided the project into sections to ensure that you can easily select the phase that is important to you in case you do not wish to code the full application.
Create and run ML pipelines - Azure Machine Learning
In this article, you learn how to create and run machine learning pipelines by using the Azure Machine Learning SDK. Use ML pipelines to create a workflow that stitches together various ML phases. Then, publish that pipeline for later access or sharing with others. Track ML pipelines to see how your model is performing in the real world and to detect data drift. ML pipelines are ideal for batch scoring scenarios, using various computes, reusing steps instead of rerunning them, and sharing ML workflows with others. For guidance on creating your first pipeline, see Tutorial: Build an Azure Machine Learning pipeline for batch scoring or Use automated ML in an Azure Machine Learning pipeline in Python.
Looking For A Match: Self-supervised Clustering For Automatic Doubt Matching In e-learning Platforms
Joshi, Vedant Sandeep, Tatinati, Sivanagaraja, Wang, Yubo
Recently, e-learning platforms have grown as a place where students can post doubts (as a snap taken with smart phones) and get them resolved in minutes. However, the significant increase in the number of student-posted doubts with high variance in quality on these platforms not only presents challenges for teachers' navigation to address them but also increases the resolution time per doubt. Both are not acceptable, as high doubt resolution time hinders the students learning progress. This necessitates ways to automatically identify if there exists a similar doubt in repository and then serve it to the teacher as the plausible solution to validate and communicate with the student. Supervised learning techniques (like Siamese architecture) require labels to identify the matches, which is not feasible as labels are scarce and expensive. In this work, we, thus, developed a label-agnostic doubt matching paradigm based on the representations learnt via self-supervised technique. Building on prior theoretical insights of BYOL (bootstrap your own latent space), we propose custom BYOL which combines domain-specific augmentation with contrastive objective over a varied set of appropriately constructed data views. Results highlighted that, custom BYOL improves the top-1 matching accuracy by approximately 6\% and 5\% as compared to both BYOL and supervised learning instances, respectively. We further show that both BYOL-based learning instances performs either on par or better than human labeling.

[FREE] Theory Of Time Series Analysis/Forecasting
In this course the student will learn the theory of time series analysis and forecasting. Time series analysis is part of artificial intelligence (AI) and is used by many companies to make predictions on sales, temperature, energy consumption, stock prices, etcetera. Time series analysis involves looking at the time series and making judgements based on the look of the time series. The time series may need to be changed in an attempt to analyse it, and these changes could involve resampling or transforming in some fashion. Time series forecasting involves making predictions on the time series.

Multi-Task Learning and HydraNets with PyTorch - PyImageSearch
Today, we will learn about Multi-Task Learning and HydraNets. This is a Deep Learning technique I first introduced back in mid-2020 in an email I sent to exactly 653 people. The responses to this email were so high (engineers from everywhere around the planet told me they loved it and wanted to apply it to their company) I had to create an entire HydraNet section in my course catalog. You can learn more by visiting https://www.thinkautonomous.ai/ Not only is this technique new and exciting for the Deep Learning field, but it's also accessible to many Computer Vision Engineers.
