Fair Risk Minimization under Causal Path-Specific Effect Constraints

Fair Risk Minimization under Causal Path-Specific Effect Constraints

arXiv:2408.01630v1 Announce Type: new Abstract: This paper introduces a framework for estimating fair optimal predictions using machine learning where the notion of fairness can be quantified using path-specific causal effects. We use a recently developed approach based on Lagrange multipliers for infinite-dimensional functional estimation to derive closed-form solutions for constrained optimization based on mean squared error and cross-entropy risk criteria. The theoretical forms of the solutions are analyzed in detail and described as nuanced adjustments to the unconstrained minimizer. This analysis highlights important trade-offs between risk minimization and achieving fairnes. The theoretical solutions are also used as the basis for…

macOS Sequoia may require weekly permissions for screen recording apps

macOS Sequoia may require weekly permissions for screen recording apps

macOS Sequoia will require regular permissions updates to use screen recording and screen-sharing capabilities. The software is in its , and the new Apple operating system has added pop-up notifications that will ask users to confirm that software has access to the device's video and audio. For now, there doesn't appear to be a way to permanently grant permissions to third-party apps. Developers confirmed with that this is a feature, not a bug. We've reached out to Apple for more information and will update this post with any additional details we receive.These permissions alerts in Sequoia will pop up weekly,…

If Tim Walz is elected vice president, his current lieutenant governor could make history

If Tim Walz is elected vice president, his current lieutenant governor could make history

If Harris and Walz win in November, or Walz steps down to focus on campaigning, his second in charge, Flanagan, would take charge, per Minnesota's constitution.In doing so, Flanagan would make history as the first woman governor of Minnesota and the first Native American woman to assume the role of governor in any state.According to Flanagan's official biography, she is a member of the White Earth Band of Ojibwe and the highest-ranking Native woman elected to an executive office.Flanagan began her political career in 2002 working for former US Sen. Paul Wellstone's campaign, per the MinnPost.Later, between 2005 and 2009,…

SceneMotion: From Agent-Centric Embeddings to Scene-Wide Forecasts

SceneMotion: From Agent-Centric Embeddings to Scene-Wide Forecasts

arXiv:2408.01537v1 Announce Type: new Abstract: Self-driving vehicles rely on multimodal motion forecasts to effectively interact with their environment and plan safe maneuvers. We introduce SceneMotion, an attention-based model for forecasting scene-wide motion modes of multiple traffic agents. Our model transforms local agent-centric embeddings into scene-wide forecasts using a novel latent context module. This module learns a scene-wide latent space from multiple agent-centric embeddings, enabling joint forecasting and interaction modeling. The competitive performance in the Waymo Open Interaction Prediction Challenge demonstrates the effectiveness of our approach. Moreover, we cluster future waypoints in time and space to quantify the interaction between agents.…

When to Consider Design Patterns

When to Consider Design Patterns

This week, at the study group, our engineer asked a question: Should we follow the design pattern to design and implement the project from the beginning? The design pattern mentioned here refers to GoF's Design Patterns. Meanwhile, there is a related context which suggests that our coding should follow SOLID principle as much as possible, especially the first S and the second O, anyway. Since SOLID principle should be followed as much as possible, then the design pattern should also be taken into consideration from the very beginning, right? No, not really. What are design patterns? The design patterns we…

Super Micro’s Weak Profit Fuels AI Server Margin Anxieties

Super Micro Computer Inc. fell more than 10% in extended trading after reporting quarterly revenue and profit that missed analysts’ estimates, outweighing an annual sales outlook that was billions above Wall Street projections.Profit, excluding some items, was $6.25 a share in the period ended June 30, the company said Tuesday in a statementBloomberg Terminal. That’s short of Super Micro’s previous forecast and the $8.25 average analyst estimate. Sales were $5.31 billion, compared with an average projection of $5.32 billion, according to data compiled by Bloomberg. Source link lol

Tracking Emotional Dynamics in Chat Conversations: A Hybrid Approach using DistilBERT and Emoji Sentiment Analysis

Tracking Emotional Dynamics in Chat Conversations: A Hybrid Approach using DistilBERT and Emoji Sentiment Analysis

arXiv:2408.01838v1 Announce Type: new Abstract: Computer-mediated communication has become more important than face-to-face communication in many contexts. Tracking emotional dynamics in chat conversations can enhance communication, improve services, and support well-being in various contexts. This paper explores a hybrid approach to tracking emotional dynamics in chat conversations by combining DistilBERT-based text emotion detection and emoji sentiment analysis. A Twitter dataset was analyzed using various machine learning algorithms, including SVM, Random Forest, and AdaBoost. We contrasted their performance with DistilBERT. Results reveal DistilBERT's superior performance in emotion recognition. Our approach accounts for emotive expressions conveyed through emojis to better understand participants'…

He’s 40, single, and living in one of the world’s most expensive cities. How one guy plans to retire by 50 and leave the rat race behind.

He’s 40, single, and living in one of the world’s most expensive cities. How one guy plans to retire by 50 and leave the rat race behind.

Christopher How's early retirement journey began with simply tracking his spending.How, a Singaporean, was 30 when he encountered a popular personal finance blog called Mr. Money Mustache. The blog introduced him to the idea of a life beyond a 9-to-5 job."The original goal was just tracking my finances, knowing where my money is going," How told Business Insider.Around two years into monitoring his expenses, the marketing professional decided he wanted to retire by 50.With that goal in mind, he started a blog to find like-minded people and create a tool for himself."I'm the kind person that if I write it…

Lumen Technologies Extends Record Rally on AI Hopes

Lumen Technologies Extends Record Rally on AI Hopes

Lumen Technologies Inc. shares surged as much as 93% in post-market trading Tuesday, extending gains after notching a record one-day jump in the regular session.Driving the gains was excitement over artificial intelligence and its ability to translate into results for the company. In earnings released after the bell Tuesday, Lumen raised its forecast for free cash flow for the year, saying it expected between $1 billion and $1.2 billion. Previously, it had forecast free cash flow between $100 million and $300 million. Wall Street analysts covering the company expected the forecast to be about $217 billion, data compiled by Bloomberg…

Data-Driven Machine Learning Approaches for Predicting In-Hospital Sepsis Mortality

Data-Driven Machine Learning Approaches for Predicting In-Hospital Sepsis Mortality

arXiv:2408.01612v1 Announce Type: new Abstract: Background: Sepsis is a severe condition responsible for many deaths worldwide. Accurate prediction of sepsis outcomes is crucial for timely and effective treatment. Although previous studies have used ML to forecast outcomes, they faced limitations in feature selection and model comprehensibility, resulting in less effective predictions. Thus, this research aims to develop an interpretable and accurate ML model to help clinical professionals predict in-hospital mortality. Methods: We analyzed ICU patient records from the MIMIC-III database based on specific criteria and extracted relevant data. Our feature selection process included a literature review, clinical input refinement, and…
