What’s the right recipe for accurate multi-mannequin forecasting on Databricks?

Introduction

Effective time collection forecasting lies at the heart of efficient stock and demand management practices within many organizations. By combining insights from past periods with forecasts of potential scenarios, businesses can accurately anticipate revenue streams and product offerings, allowing them to strategically deploy resources to meet projected demands effectively. As companies seek to optimize their forecasting processes, they continually investigate innovative strategies to refine accuracy, enabling timely and targeted investments that minimize capital expenditures while maximizing ROI.

For numerous organisations, the major challenge lies in navigating the diverse array of forecasting strategies available to them. Traditional statistical methods, generalized additive models, machine learning techniques, and deep learning approaches have evolved to be complemented by pre-trained generative AI transformers, offering a diverse array of options that perform differently depending on the context.

While many proponents of mannequin creation tout enhanced forecasting precision relative to benchmark datasets, the reality is that geographical data and business requirements often narrow the choice of models down to just a few viable options, making practical application and testing against an organization’s own datasets the only way to determine which performs best. What constitutes “finest” performance metrics can differ significantly across forecasting units and evolve over time, compelling organisations to continually assess and compare their approaches to identify the most effective tactics for each distinct scenario.

We will delve into a comprehensive framework for conducting comparative analyses of forecasting trends on this blog. MMF enables clients to train and forecast using various predictive models at scale, processing hundreds of thousands to tens of millions of time-series data points at their finest level of detail. With streamlined support for information preparation, backtesting, cross-validation, scoring, and deployment, the framework empowers forecasting teams to seamlessly implement a comprehensive forecast-generation solution by leveraging both traditional and cutting-edge approaches, prioritizing configurability over coding to efficiently integrate new models and capabilities into their workflows. In numerous customer deployments, our framework has already gained traction.

The Many-Mannequin Forecasting (MMF) framework is made available as an open-source GitHub repository, featuring fully accessible, easy-to-understand, and thoroughly commented source code. Organizations can utilize this framework as-is, or extend it according to their unique needs and goals, allowing for customized performance enhancements that cater specifically to their specific requirements.

The MMF incorporates native support for more than 40 fashion styles through seamless integration with leading open-source forecasting libraries, including TensorFlow, PyTorch, Statsmodels, Prophet, ARIMA, LSTM, SARIMA, and XGBoost. As our customers explore emerging trends, we aim to provide even greater support.

By leveraging pre-integrated fashion capabilities within the framework, clients can eliminate the need for tedious knowledge preparation and model training unique to each model, allowing them to focus on analysis and deployment, thereby significantly accelerating time-to-market. For data science teams and machine learning engineers operating with limited resources and driven by business stakeholders seeking tangible results, this solution offers a substantial competitive advantage.

By leveraging the Multi-Model Framework (MMF), forecasting teams can simultaneously explore various models, seamlessly integrating both pre-built and customized logics to select the optimal model for each dataset, thereby boosting the overall precision of their predictive outcomes. Deployed to a Databricks cluster, the MMF harnesses the entire wealth of pre-existing data to accelerate model training and analysis through automated parallel processing capabilities. Groups simply specify their preferred source configurations, allowing the Market Mix Forecasting (MMF) module to handle the rest.

Concentrate on Mannequin Outputs & Comparative Evaluations

Standardizing mannequin outputs holds paramount importance for the Medical Modeling Foundation (MMF). During the process of generating forecasts with MMF, the system produces two critical output tables: evaluation_output and scoring_output, facilitating a comprehensive assessment of the forecast’s performance. The evaluation output provides a comprehensive summary of each model’s performance, detailing the aggregated results from all backtesting intervals across various time series and formats. This combination of forecasts and actuals empowers customers to create tailored metrics that seamlessly align with their unique business requirements. While MMF offers an array of innovative metrics – including MAE, MSE, RMSE, MAPE, and SMAPE – its flexibility in creating customised metrics empowers users to conduct meticulous analysis and select or ensemble models, thereby ensuring the optimal attainment of forecasting results.

The second module, scoring_output (Determine 2), aggregates forecasts for each time interval across all models. Using the comprehensive analysis results stored in the evaluation_output table, you can select predictions from the top-performing model or a combination of models. By combining the most accurate forecasts from a range of competing approaches or ensembles, you can achieve significantly improved accuracy and stability compared to relying solely on a single model, ultimately enhancing the overall effectiveness of your large-scale predictive solution.

Streamline Mannequin Management through Intelligent Automation

Developed on the Databricks platform, the MMF seamlessly integrates with its Mosaic AI capabilities, providing automated logging of parameters, aggregated metrics, and fashioning (both international and basis patterns) as outlined in Figure 3. As a core component of Databricks’ ecosystem, forecasting teams can leverage granular access control and meticulous model governance to manage their models, extending beyond mere output visualization.

When deploying a workforce, teams must reuse trained models by loading them onto their cluster using MLflow’s method, or deploy them behind a real-time endpoint using (refer to Figure 4). With a time-series data basis, fashions hosted in Mannequin Serving allow for generating multi-step ahead forecasts at any given time, provided that you furnish the historical context at the relevant scale. This functionality significantly improves capabilities for on-demand forecasting, enabling real-time monitoring and streamlining performance tracking.
