本课程“使用时间序列、LightGBM 和随机森林预测销售额”是一项以项目为导向的综合性课程,旨在教授学员如何一步步构建销售预测模型。课程将机器学习与销售分析相结合,是提升数据科学技能的绝佳机会。 课程重点关注三个主要方面: 1. **数据分析:** 从多个角度探索销售报告数据集。 2. **客户细分分析:** 进行深入的客户细分研究。 3. **销售预测模型构建:** 使用时间序列、LightGBM、随机森林、LSTM 和 SARIMA(季节性自回归积分移动平均模型)构建预测模型。 在课程的介绍部分,学员将学习销售预测的基本原理,包括了解将要使用的预测模型,以及销售预测如何帮助识别消费者行为。 随后,课程将详细介绍时间序列预测的完整步骤,涵盖数据收集、预处理、训练集与测试集划分、模型选择、模型训练和预测。 此外,课程还将探讨影响销售业绩的多种因素,例如产品质量、营销策略、季节性趋势、市场饱和度、供应链效率和宏观经济因素。 在具备了销售预测模型的必要知识后,课程将进入项目实践阶段。学员将学习如何设置 Google Colab IDE,以及如何从 Kaggle 查找和下载销售报告数据集。 项目部分将分为三个主要环节: 1. **数据分析与可视化:** 从不同角度探索数据集。 2. **客户细分分析:** 分步进行详尽的客户细分。 3. **销售预测:** 使用时间序列、LightGBM、随机森林、LSTM 和 SARIMA 进行销售预测。 课程最后,学员将通过计算平均绝对误差(Mean Absolute Error)和进行残差分析来评估销售预测模型的准确性和性能。 **学习要点包括:** * 掌握销售预测的基础知识。 * 理解时间序列预测模型的工作原理(数据收集、探索、预处理、训练测试集划分、模型选择、训练和预测)。 * 了解影响销售业绩的因素(如季节趋势、市场饱和度、供应链效率)。 * 学习从 Kaggle 下载和处理数据集(去除缺失行和重复值)。 * 学习进行客户细分分析。 * 学习分析订单履行效率和销售业绩趋势。 * 学习使用 ARIMA、SARIMA、LightGBM、随机森林和 LSTM 构建销售预测模型。 * 学习评估预测模型的准确性与性能(计算平均绝对误差、进行残差分析)。 **额外项目:** * **销售 KPI 学习:** 掌握转化率、销售增长、客户流失率、客户生命周期价值 (CLV) 和客户获取成本等关键销售 KPI。 * **使用 XGBoost 预测销售额:** 学习使用 XGBoost 进行销售预测。 * **使用 GRU 预测销售额:** 学习使用 GRU(门控循环单元)进行时间序列销售预测。 **学习销售预测的意义:** 在动态市场中,销售预测是企业的战略要务。掌握销售预测有助于企业预见市场趋势、理解消费者行为、优化资源配置,从而在竞争中保持领先,适应需求变化,并做出明智的决策以驱动业务成功。同时,通过构建销售预测项目,还能提升数据科学和机器学习技能。需要注意的是,无论模型的先进程度如何,销售预测都不可能达到 100% 的准确性。
Welcome to Forecasting Sales with Time Series, LightGBM & Random Forest course. This is a comprehensive project based course where you will learn step by step on how to build sales forecasting models. This course is a perfect combination between machine learning and sales analytics, making it an ideal opportunity to enhance your data science skills. This course will be mainly concentrating on three major aspects, the first one is data analysis where you will explore the sales report dataset from multiple angles, the second one is to conduct customer segmentation analysis, and the third one is to build sales forecasting models using time series, LightGBM, Random Forest, LSTM, and SARIMA (Seasonal Autoregressive Integrated Moving Average). In the introduction session, you will learn the basic fundamentals of sales forecasting, such as getting to know forecasting models that will be used and also learn how sales forecasting can help us to identify consumer behavior. Then, in the next session, we are going to learn about the full step by step process on how time series forecasting works. This section will cover data collection, preprocessing, splitting the data into training and testing sets, selecting model, training model, and forecasting. Afterward, you will also learn about several factors that contribute to sales performance, for example, product quality, marketing strategies, seasonal trends, market saturation, supply chain efficiency, and macro economic factors. Once you have learnt all necessary knowledge about the sales forecasting model, we will start the project. Firstly you will be guided step by step on how to set up Google Colab IDE. In addition to that, you will also learn to find and download sales report dataset from Kaggle, Once, everything is ready, we will enter the main section of the course which is the project section The project will be consisted of three main parts, the first part is the data analysis and visualization where you will explore the dataset from various angles, in the second part, you will learn step by step on how to conduct extensive customer segmentation analysis, meanwhile, in the third part, you will learn how to forecast sales using time series, LightGBM, Random Forest, LSTM, and Seasonal Autoregressive Integrated Moving Average. At the end of the course, you will also evaluate the sales forecasting model's accuracy and performance using Mean Absolute Error and residual analysis.First of all, before getting into the course, we need to ask ourselves this question: why should we learn to forecast sales? Well, here is my answer, Forecasting sales is a strategic imperative for businesses in today's dynamic market. By mastering the art of sales forecasting, we gain the power to anticipate market trends, understand consumer behavior, and optimize resource allocation. It's not just about predicting numbers, it's about staying ahead of the competition, adapting to changing demands, and making informed decisions that drive business success. In addition to that, by building this sales forecasting project, you will level up your data science and machine learning skills. Last but not least, even though forecasting sales can be very useful, however, you still need to be aware that no matter how advanced your forecasting model is, there is no such thing as 100% accuracy when it comes to forecasting.Below are things that you can expect to learn from this course:Learn the basic fundamentals of sales forecastingLearn how time series forecasting models work. This section will cover data collection, data exploration, preprocessing, train test split, model selection, model training, and forecastingLearn about factors that can contribute to sales performance, such as seasonal trends, market saturation and supply chain efficiencyLearn how to find and download datasets from KaggleLearn how to clean dataset by removing missing rows and duplicate valuesLearn how to conduct customer segmentation analysisLearn how to analyze order fulfillment efficiencyLearn how to analyze sales performance trendLearn how to build sales forecasting model using ARIMA, SARIMA, LightGBM, Random Forest, and LSTMLearn how to evaluate forecasting model's accuracy and performance by calculating mean absolute error and conduct residual analysisAdditional ProjectsLearning about KPIs in Sales: In this project, you'll dive into crucial sales KPIs such as conversion rate, sales growth, churn rate, customer lifetime value (CLV), and customer acquisition cost. These KPIs provide valuable insights into the effectiveness of sales strategies and help businesses optimize their performance.Forecast Sales Using XGBoost: This project will guide you through forecasting sales using XGBoost, a powerful machine learning algorithm. You'll learn how to use historical data to make accurate predictions about future sales, enabling businesses to plan more effectively.Forecast Sales Using GRU: In this project, you'll explore forecasting sales with GRU (Gated Recurrent Unit), a type of neural network that works well with time series data. By applying GRU, you'll be able to generate accurate sales forecasts that account for trends and patterns over time.
