As China's pillar industry, the property market has suffered a considerable impact in recent years, with a decline in turnover and many developers at risk of bankruptcy. As one of the most concerned factors for stakeholders, housing prices need to be predicted more objectively and accurately to minimize decision-making errors by developers and consumers. Many prediction models in recent years have been unfriendly to consumers due to technical difficulties, high data demand, and varying factors affecting house prices in different regions. A uniform model across the country cannot capture local differences accurately, so this study compares and analyses the fitting effects of multiple machine learning models using February 2024 new building data in Changsha as an example, aiming to provide consumers with a simple and practical reference for prediction methods. The modeling exploration applies several regression techniques based on machine learning algorithms, such as Stepwise regression, Robust regression, Lasso regression, Ridge regression, Ordinary Least Squares (OLS) regression, Extreme Gradient Boosted regression (XGBoost), and Random Forest (RF) regression. These algorithms are used to construct forecasting models, and the best-performing model is selected by conducting a comparative analysis of the forecasting errors obtained between these models. The research found that machine learning is a practical approach to property price prediction, with least squares regression and Lasso regression providing relatively more convincing results.

Abstract
A publicly accessible database of ants associated with dry forest fragments and urban environments in Santa Marta, Colombia, is presented through the Colombian Biodiversity Information System (SIB). Capture methods included the installation of pitfall traps, protein and carbohydrate baits, extraction by the Winkler method of ants associated with leaf litter and manual collection of ants foraging on tree vegetation. The dataset contains 54 323 records, distributed in seven subfamilies, 42 genera, 88 species and nine morphospecies. This list is a tool to encourage the study and conservation of ants in urban areas.
