机器学习(Machine Learning)是一种基于计算机算法的自动数据分析技术,用于从数据中学习并预测未来的结果。它是人工智能(AI)和数据挖掘(Data Mining)的子领域,旨在通过训练和调整算法来发现数据中的模式、关系和规律。
机器学习算法可以分为监督学习、无监督学习和半监督学习三类:
1. 监督学习(Supervised Learning):在这种类型的学习中,算法被提供带有标签的数据集,用于训练。算法学习如何将输入数据映射到输出数据,并在新数据上进行预测。常见的监督学习算法包括逻辑回归、决策树、支持向量机(SVM)、随机森林和神经网络。
2. 无监督学习(Unsupervised Learning):在这种类型的学习中,算法没有标签数据。算法学习数据中的模式、结构和关系,并可能发现新的数据集群或特征。常见的无监督学习算法包括聚类、主成分分析(PCA)、独立成分分析(ICA)和高维度数据降维。
3. 半监督学习(Semi-supervised Learning):在这种类型的学习中,算法被提供部分带有标签的数据集。算法学习如何将输入数据映射到输出数据,并在新数据上进行预测。半监督学习算法结合了监督学习和无监督学习的优点,常见的半监督学习算法包括自我标注(Self-Labeling)和基于图的半监督学习(Graph-based Semi-supervised Learning)。
机器学习的应用广泛,包括自然语言处理、计算机视觉、推荐系统、人工智能和自动驾驶等领域。它的优势包括:
1. 自动化:机器学习算法可以自动从数据中发现模式和关系,无需人为干预。
2. 高效性:机器学习算法可以处理大量数据,并且可以在不需要人为干预的情况下进行预测。
3. 适应性:机器学习算法可以根据数据集的变化和更新进行调整。
4. 精准性:机器学习算法可以通过训练和测试来提高预测的准确性。

This model extends LLama-3 8B's context length from 8k to -> 160K, developed by Gradient, sponsored by compute from Crusoe Energy. It demonstrates that SOTA LLMs can learn to operate on long context with minimal training (< 200M tokens) by appropriately adjusting RoPE theta.

Infra:
We build on top of the EasyContext Blockwise RingAttention library [3] to scalably and efficiently train on contexts up to 262144 tokens on Crusoe Energy high performance L40S cluster.
Data:
For training data, we generate long contexts by augmenting SlimPajama.
