英文摘要：
Matrix factorization was used to generate investment recommendations for investors. An iterative conjugate gradient method was used to optimize the regularized squared-error loss function. The number of latent factors, number of iterations, and regularization values were explored. Overfitting can be addressed by either early stopping or regularization parameter tuning. The model achieved the highest average prediction accuracy of 13.3%. With a similar model, the same dataset was used to generate investor recommendations for companies undergoing fundraising, which achieved highest prediction accuracy of 11.1%.

中文摘要：
矩阵分解用于为投资者生成投资建议。采用迭代共轭梯度法优化正则化的平方误差损失函数。探讨了潜在因素的数量、迭代次数和正则化值。可以通过提前停止或正则化参数调整来解决过拟合问题。该模型的平均预测精度最高，为13.3%。在一个类似的模型中，使用相同的数据集为正在筹款的公司生成投资者建议，预测准确率最高，为11.1%。
