合集：AI案例-CV-动物
赛题：鸟类品种识别挑战赛
主办方：科大讯飞
数据集：200种鸟类数据集
数据集价值：鸟类品种识别
一、赛题描述
随着生态环境的不断变化和人类对自然资源的过度开发，世界各地的鸟类数量和种类正在发生着巨大的变化。为了更好地保护鸟类资源，科学家们需要对鸟类进行详细的研究和记录。然而，传统的鸟类观察方法往往需要大量的人力、时间和物力，而且在观察过程中还可能会对鸟类造成不必要的干扰。为了解决这个问题，人工智能四技术成为了一个非常有前途的解决方案。利用人工智能技术，我们可以自动地识别和分类各种 不同的只鸟类，实现对鸟类的高效监测和保护。 比赛预期目标比赛旨在通过人工智能技术实现对鸟类图片的自动识别和分类。比赛的参赛者需要基于提供的鸟类图片数据集，设计和训练一个能够高效、准确地识别和分类不同鸟类的人工智能模型。比赛的评判标准为模型的准确率、召回率、精确率等指标。通过本次比赛，我们希望能够促进人工智能技术在鸟类保护领域的应用和推广，为保护鸟类资源作出贡献。
