孕妇人群菜品推荐AI训练数据
收藏资源简介：
孕妇人群菜品推荐AI训练数据的价值在于其为构建精准、高效的孕妇菜品推荐AI模型提供了丰富且具针对性的信息基础。这些数据覆盖了孕妇的关键特征，包括年龄、性别、健康状况和饮食习惯，使AI模型能够深入学习并掌握这些因素对菜品选择的影响。通过利用这些数据进行训练，AI模型能够更加准确地识别孕妇的营养需求和饮食限制，进而在实际应用中提供更加个性化的菜品推荐。这一训练过程的核心价值在于提升AI模型的预测精确度和适应能力，确保其在面对现实世界的复杂多变情况时，能够做出更加符合孕妇实际需求的决策。1.数据生成与预处理：使用Featuretools（一种特征生成工具）随机生成孕妇人群的特征信息，包括生成时间、人群类别、年龄、性别、健康状况、饮食习惯。通过数据清洗去除无效或错误记录，确保数据质量。 2.特征工程：跟据生成时间、年龄、性别、健康状况和饮食习惯，使用Feature-engine工具进行特征转换，生成特征标签。 3.菜品筛选：跟据特征标签，调用孕妇人群带量菜品知识库，运用SQL查询筛选出符合条件的推荐菜品。到此步骤为止，孕妇人群的特征信息、特征标签和推荐菜品共同构成训练集。 4.深度学习架构选择：采用深度交叉网络（DCN）作为深度学习架构。 5.模型训练：运用训练集对DCN模型进行训练。使用二元交叉熵损失函数来优化模型。采用Adam优化器进行参数更新。使用正则化技术（如L2正则化）来防止过拟合。 6.模型评估：使用准确率、召回率和F1分数来评估模型性能。通过交叉验证来评估模型的稳定性PSI。
The value of the AI training dataset for meal recommendation targeting pregnant women lies in providing a rich and targeted information foundation for building an accurate and efficient AI meal recommendation model for this population. These data cover key characteristics of pregnant women, including age, gender, health status and dietary habits, enabling the AI model to deeply learn and grasp the impact of these factors on meal selection. By training with this dataset, the AI model can more accurately identify the nutritional needs and dietary restrictions of pregnant women, thereby providing more personalized meal recommendations in practical applications. The core value of this training process lies in improving the prediction accuracy and adaptability of the AI model, ensuring that it can make decisions that better meet the actual needs of pregnant women when facing the complex and changing scenarios in the real world. 1. Data Generation and Preprocessing: Use Featuretools, a feature generation tool, to randomly generate characteristic information of the pregnant population, including generation time, population category, age, gender, health status and dietary habits. Perform data cleaning to remove invalid or erroneous records and ensure data quality. 2. Feature Engineering: According to the generation time, age, gender, health status and dietary habits, use the Feature-engine tool to conduct feature transformation and generate feature labels. 3. Meal Screening: According to the feature labels, call the portioned meal knowledge base for the pregnant population, and use SQL queries to filter out eligible recommended meals. Up to this step, the characteristic information of the pregnant population, feature labels and recommended meals jointly constitute the training dataset. 4. Deep Learning Architecture Selection: Adopt the Deep & Cross Network (DCN) as the deep learning architecture. 5. Model Training: Train the DCN model using the training dataset. Use the Binary Cross-Entropy Loss function to optimize the model. Adopt the Adam optimizer for parameter updating. Use regularization techniques (such as L2 regularization) to prevent overfitting. 6. Model Evaluation: Evaluate model performance using accuracy, recall and F1-score. Assess the model's stability via cross-validation and the Population Stability Index (PSI).
