AI Solutions

Machine Learning and Predictive Analytics Services

Predict demand, churn, risk and failures before they happen, and put those predictions directly into the decisions and systems your teams use every day.

Move from Reporting the Past to Predicting What Comes Next

Dashboards tell you what happened last month. Predictive models tell you which customers are likely to leave, how much stock each store will need next week, which transactions look fraudulent and which machines are close to failure. For many business decisions, classical machine learning on structured data remains the most accurate, explainable and cost-effective form of AI, often outperforming larger and more fashionable models at a fraction of the cost.

Hanoi Technology designs, builds and operates machine learning solutions end to end. We frame the business problem precisely, engineer reliable features from your data, choose models that balance accuracy with explainability, and deploy them with automated pipelines and monitoring. Just as important, we embed predictions into workflows, so a forecast changes an order quantity and a risk score changes an approval.

The Challenge

Why Predictive Models Fail to Deliver Value

Accurate models in a notebook are common; models that change business outcomes are rare.

Poorly Framed Problems

Teams predict what is easy to measure instead of what drives a decision. A churn model that flags customers too late to act, or at a granularity no one can use, delivers impressive metrics and no value.

Data Leakage and Weak Features

Models trained with information that would not be available at prediction time look excellent in testing and disappoint in production. Inconsistent feature logic between training and serving causes similar silent failures.

Models That Decay Unnoticed

Customer behavior, prices and operations change, and models trained on last year’s patterns gradually lose accuracy. Without monitoring for data and concept drift, the decline is only discovered after decisions go wrong.

Predictions That Never Reach the Workflow

Scores delivered as a weekly spreadsheet are ignored. Value appears only when predictions are integrated into CRM, ERP, pricing or operational systems with clear actions attached.

Business Value

Business Outcomes from Predictive Analytics

More Accurate Planning

Forecasts at the right granularity reduce stockouts, overstock and idle capacity. Planners start from a statistically sound baseline and adjust for what they know.

Customers Retained Proactively

Churn and propensity models identify at-risk or high-potential customers early. Retention and sales teams act while there is still time to influence the outcome.

Lower Risk and Fraud Losses

Risk scores evaluate applications, claims and transactions consistently and in real time. Analysts focus investigations on the cases most likely to matter.

Less Unplanned Downtime

Anomaly detection and failure prediction on sensor and log data allow maintenance before breakdowns. Operations move from reactive repair to planned intervention.

Explainable Decisions

Feature attribution and clear model documentation show why a prediction was made. Business users, auditors and customers can understand and challenge outcomes.

Reusable Data Assets

Curated features and pipelines built for one model accelerate the next. Each project strengthens your data foundation rather than creating another silo.

The Right Model Is the Simplest One That Works

A well-tuned gradient boosting model with strong features often beats a complex deep network on business data, and is easier to explain, cheaper to run and simpler to maintain. We let evidence, not hype, choose the model.

Our Approach

How We Build Predictive Solutions

A disciplined lifecycle that guards against leakage, overfitting and models nobody uses.

  1. 01

    Frame the Decision

    We define what will be predicted, how far ahead, at what level and which decision the prediction will change, along with the baseline and the success metric.

    Deliverables: Problem statement · Baseline and KPI definition

  2. 02

    Prepare Data and Features

    We profile source data, resolve quality issues and engineer time-correct features that would genuinely be available at prediction time.

    Deliverables: Data quality report · Feature specification

  3. 03

    Model and Validate

    We train candidate models, tune them with proper cross-validation or backtesting and compare them against simple baselines and business rules.

    Deliverables: Model comparison report · Explainability analysis

  4. 04

    Deploy and Integrate

    We deploy the selected model as a batch job or real-time API, integrate it into target systems and run a controlled rollout or A/B test.

    Deliverables: Deployed model service · Integration and test results

  5. 05

    Monitor and Improve

    We track input drift, prediction quality and business impact, retrain on schedule or when alerts fire, and maintain documentation for audit.

Use Cases

Predictive Analytics Use Cases

Proven applications of machine learning across industries.

Store-Level Demand Forecasting

A retailer forecasts daily demand per product and store, including promotion and holiday effects. Replenishment orders are generated from forecasts instead of fixed min-max rules.

Subscription Churn Prediction

A SaaS or telecom business scores every account weekly for churn risk and its main drivers. Customer success teams receive prioritized lists with suggested actions.

Property Valuation Models

A real estate platform estimates fair market prices from location, size, amenities and comparable sales. Agents and buyers see an estimated range with the factors behind it.

Transaction Fraud Detection

A payment provider scores transactions in milliseconds using behavior and device features. Suspicious payments are held for review while legitimate ones flow without friction.

Predictive Maintenance

A manufacturer detects abnormal vibration and temperature patterns from equipment sensors. Maintenance is scheduled before failure, reducing unplanned downtime.

Machine Learning and Predictive Analytics FAQ

How much data do we need to build a predictive model?

It depends on the problem more than on a fixed number. Forecasting usually benefits from at least two years of history to capture seasonality, while classification models need enough examples of the outcome you want to predict, such as churned customers or fraudulent transactions. Data relevance and quality matter as much as volume. In the discovery phase we profile your data and tell you honestly whether it supports a reliable model or what additional data would be needed.

How accurate will the model be?

We cannot promise a specific figure before seeing the data, and you should be cautious of anyone who does. What we commit to is measuring accuracy properly, on held-out data or through backtesting that simulates real use, and comparing it with your current method. You see the uplift over the baseline, error ranges and where the model performs weakly, so you can decide whether the improvement justifies deployment.

What does a machine learning project typically cost?

Costs are driven by data preparation effort, the number of models, integration requirements and whether real-time scoring is needed. A proof of value on one use case is usually a fixed-scope engagement of six to ten weeks. Production deployment with MLOps and integration is estimated separately once the proof of value confirms the approach. Ongoing costs cover cloud compute for training and scoring, and optional managed services for monitoring and retraining.

How do you make sure models stay accurate over time?

Every production model we deliver includes monitoring for input data drift, prediction distribution changes and, when ground truth arrives, actual accuracy. Alerts notify the team when metrics breach agreed thresholds. Retraining pipelines are automated and versioned, and new models are validated against the current one before promotion. Monthly or quarterly model reviews, included in our managed service, look at business impact as well as statistics.

Can you explain why a model made a particular prediction?

Yes. We use interpretable models where regulation or trust requires it, and apply techniques such as SHAP values to explain more complex models. Each prediction can be accompanied by its main contributing factors, and we produce global explanations showing which features drive the model overall. This supports regulatory requirements, helps business users trust the output and often reveals data issues that improve the model further.

Will the model work with our existing systems?

We design integration from the start. Batch predictions can be written to your data warehouse, CRM or ERP on a schedule, while real-time models are exposed as secure APIs with defined latency targets. We work with common platforms such as Salesforce, Dynamics 365, SAP, Snowflake and Databricks, as well as custom applications. Integration effort is identified during discovery so it is part of the plan, not a surprise.
