  1. New Photos Reveal Holes in NASA Mars Rover Wheels, but They're Still Turning

    by , 09-28-2024 at 04:57 AM
    NASA's Curiosity rover has been exploring the Gale Crater on Mars since 2012. That's a long time to weather dust storms, drive along the base of a mountain and crawl over endless pointy rocks. The rover's aluminum wheels have taken a beating. New images show some dramatic gaping holes, but don't be alarmed. NASA has it under control.
    The photos are eye-opening. Curiosity has six wheels and some are worse off than others. The right-middle wheel looks rough, but "is still holding up well despite ...

  2. Data Science and ML (Part 23): Why LightGBM and XGBoost outperform a lot of AI models?

    by , 08-15-2024 at 03:17 AM
    Gradient Boosted Decision Trees (GBDT) are a powerful machine learning technique used primarily for regression and classification tasks. They combine the predictions of multiple weak learners, usually decision trees, to create a strong predictive model.

    The core idea is to build models sequentially, each new model attempting to correct the errors made by the previous ones.

    Have gained much popularity in the machine learning community as the algorithms of choice for

  3. Population optimization algorithms: Artificial Multi-Social Search Objects (MSO)

    by , 06-05-2024 at 03:18 AM
    In the previous article, we considered the evolution of social groups where they moved freely in the search space. However, here I propose that we change this concept and assume that groups move between sectors, jumping from one to another. All groups have their own centers, which are updated at each iteration of the algorithm. In addition, we introduce the concept of memory both for the group as a whole and for each individual particle in it. Using these changes, our algorithm now allows
