Enhancing Tree Type Detection in Forest Fire Risk Assessment: Multi-Stage Approach and Color Encoding with Forest Fire Risk Evaluation Framework for UAV Imagery

[Submitted on 27 Jul 2024] View a PDF of the paper titled Enhancing Tree Type Detection in Forest Fire Risk Assessment: Multi-Stage Approach and Color Encoding with Forest Fire Risk Evaluation Framework for UAV Imagery, by Jinda Zhang and 1 other authors View PDF Abstract:Forest fires pose a significant threat to ecosystems, economies, and human health worldwide. Early detection and assessment of forest fires are crucial for effective management and conservation efforts. Unmanned Aerial Vehicles (UAVs) equipped with advanced computer vision algorithms offer a promising solution for forest fire detection and assessment. In this paper, we optimize an integrated forest…

Steamroller Problems: An Evaluation of LLM Reasoning Capability with Automated Theorem Prover Strategies

Steamroller Problems: An Evaluation of LLM Reasoning Capability with Automated Theorem Prover Strategies

[Submitted on 17 Jul 2024] View a PDF of the paper titled Steamroller Problems: An Evaluation of LLM Reasoning Capability with Automated Theorem Prover Strategies, by Lachlan McGinness and 1 other authors View PDF Abstract:This study presents the first examination of the ability of Large Language Models (LLMs) to follow reasoning strategies that are used to guide Automated Theorem Provers (ATPs). We evaluate the performance of GPT4, GPT3.5 Turbo and Google's recent Gemini model on problems from a steamroller domain. In addition to determining accuracy we make use of the Natural Language Processing library spaCy to explore new methods of…

JD Vance has the most to lose if Kamala Harris taps Minnesota Gov. Tim Walz as her running mate

JD Vance has the most to lose if Kamala Harris taps Minnesota Gov. Tim Walz as her running mate

Whoever emerges as Vice President Kamala Harris' running mate has the potential to dramatically reset the 2024 presidential race.After former President Donald Trump selected Ohio Sen. JD Vance as his vice-presidential pick, Republicans were thrilled that the GOP lawmaker's Midwestern roots and working-class upbringing would set him apart from what was previously thought to be President Joe Biden's reelection effort alongside Harris.But Harris, who's now in the driver's seat as the presumptive Democratic nominee, is currently mulling over several potential picks, which reportedly includes two-term Minnesota Gov. Tim Walz.Walz, a Nebraska native and former congressman, is seen by many Democrats…

From A-to-Z Review of Clustering Validation Indices

From A-to-Z Review of Clustering Validation Indices

arXiv:2407.20246v1 Announce Type: new Abstract: Data clustering involves identifying latent similarities within a dataset and organizing them into clusters or groups. The outcomes of various clustering algorithms differ as they are susceptible to the intrinsic characteristics of the original dataset, including noise and dimensionality. The effectiveness of such clustering procedures directly impacts the homogeneity of clusters, underscoring the significance of evaluating algorithmic outcomes. Consequently, the assessment of clustering quality presents a significant and complex endeavor. A pivotal aspect affecting clustering validation is the cluster validity metric, which aids in determining the optimal number of clusters. The main goal of this…

One of Hamas’ top leaders has been killed in Iran, according to reports

Top Hamas leader Ismail Haniyeh has been killed in Iran, according to a statement from Iran's Islamic Revolutionary Guards Corps early Wednesday.Haniyeh, 62, was the leader of Hamas' political wing. He joined the militant group in the late 1980s.In a statement published by the Hamas-affiliated Shehab news agency, the group accused Israel of killing Haniyeh in a "treacherous" attack on his residence in Tehran.Haniyeh was previously in exile in Qatar. He had traveled to Tehran to attend the inauguration of Masoud Pezeshkian, Iran's new president, according to multiple reports.No party has claimed responsibility for the killing at press time. In…

Matryoshka-Adaptor: Unsupervised and Supervised Tuning for Smaller Embedding Dimensions

Matryoshka-Adaptor: Unsupervised and Supervised Tuning for Smaller Embedding Dimensions

arXiv:2407.20243v1 Announce Type: new Abstract: Embeddings from Large Language Models (LLMs) have emerged as critical components in various applications, particularly for information retrieval. While high-dimensional embeddings generally demonstrate superior performance as they contain more salient information, their practical application is frequently hindered by elevated computational latency and the associated higher cost. To address these challenges, we propose Matryoshka-Adaptor, a novel tuning framework designed for the customization of LLM embeddings. Matryoshka-Adaptor facilitates substantial dimensionality reduction while maintaining comparable performance levels, thereby achieving a significant enhancement in computational efficiency and cost-effectiveness. Our framework directly modifies the embeddings from pre-trained LLMs which is…

The last thing JD Vance probably wants to be associated with right now is a couch. But for some reason, he’s still talking about it.

The last thing JD Vance probably wants to be associated with right now is a couch. But for some reason, he’s still talking about it.

For one, a joke that Vance may once have had intercourse with a couch has been going viral on social media platforms from X to TikTok.To be clear, the pages of Vance's bestselling memoir "Hillbilly Elegy" don't describe such a sex act. The Associated Press even tried to debunk the claim — but ended up taking the article down, saying the fact-check didn't go through its "standard editing process."So, one might wager that the last word that Vance might want to say out loud, let alone at a rally, would be "couch."Not so. At a Tuesday event in Nevada, the…

The Quest for Performance Part II : Perl vs Python

The Quest for Performance Part II : Perl vs Python

Having run a toy performance example, we will now digress somewhat and contrast the performance against a few Python implementations. First let's set up the stage for the calculations, and provide commandline capabilities to the Python script. import argparse import time import math import numpy as np import os from numba import njit from joblib import Parallel, delayed parser = argparse.ArgumentParser() parser.add_argument("--workers", type=int, default=8) parser.add_argument("--arraysize", type=int, default=100_000_000) args = parser.parse_args() # Set the number of threads to 1 for different libraries print("=" * 80) print( f"nStarting the benchmark for {args.arraysize} elements " f"using {args.workers} threads/workersn" ) # Generate the data…
