Notebook Thoughts: Enabling the Healthcare Journey

In
By Pedro Laboy
Comment

From a marketing perspective, enabling the healthcare or prescription journey is a complex landscape of intertwined stakeholders, regulations, technologies and touchpoints. The interests and needs of healthcare providers (HCPs) and patients will converge and diverge at different points. Having the right technology infrastructure and targeting strategies is key to the successful completion of this journey.

As usual, my sketch over simplifies things but it does capture the key technology platforms, data models and touchpoints at each stage of the journey. For the most part, platforms and strategies stack on top of previous ones as we move along the journey–rather than being solely use in one stage. Given that healthcare is a highly regulated industry, a strong privacy and data governance strategy is of the upmost importance.

Notebook Thoughts: Machine Learning for Dummies

In

Machine learning is an evolving and complex science. If one takes into account all possible scenarios, dependencies and models, it would be impossible to sketch an all-encompassing explanation. So I will focus on what the non-data scientist should know about machine learning. That is, they should focus on understanding available data, machine learning types, algorithm models and business applications.

1.  First, determine if what is the nature of the available data. Do you have historical campaign data with historical results or an unstructured database of customer records? Or are you trying to make real-time decisions on streaming data?

2.  The data available–and use case–will determine the appropriate machine learning approach. There are three major types: supervised, unsupervised and reinforcement learning. a) Supervised Learning allows to you to predict an outcome based on input and output data (e.g. churn). b) Unsupervised Learning allows to you categorize outcomes based on input data (e.g. segmentation). c) Reinforcement Learning allows you to react to an environment (e.g. driverless car).

3.  Each machine learning type will use a number of algorithm. There are hundreds of variations. Supervised Learning typically uses regression or classification algorithms. Unsupervised Learning uses, but is not limited to, clustering algorithms. Reinforcement Learning will usually use to type of neural network algorithm.

4.  The uses of machine learning are nearly limitless. Although I listed here as the last step, determining the use case or business application should probably be the first step. For example, we would use logistic regression to determine whether a house would sell at a certain price or not and we would use linear regression to predict the future price of a house. You should keep in mind that machine learning business applications typically require the use of more than one machine learning type as well as multiple algorithms.

I hope this sketch serves as a useful guide. Feel free to share and use as needed.

Thoughts and comments as well as suggestions for other sketched explanations are welcomed.

Notebook Thoughts: An AI Guide to Marketing

Abundance of data and advances in technology–including the proliferation of low code and no code platforms–means that Artificial Intelligence and Machine Learning (AI/ML) Marketing is at the finger tips of most organizations. If we think in terms of Data, Technology, People, and Process, the first two are not the impediment to leveraging AI/ML to drive marketing effectiveness and sales. Rather, it is the shortage of skilled people and the lack of understanding of which models and processes solve different marketing challenges.

I put this basic framework together to give an idea of different AI/ML techniques and their applications in marketing. Do keep in mind that the combination of models and applications can number in the hundreds. This is why skilled data scientists and data engineers are so important to marketing organizations. To keep things simple I selected 12 tactics with their respective algorithms across four categories.

SEGMENTATION

Product Segmentation <> Collaborative Filtering

Journey Stage Segmentation <> Gaussian Mixture

Behavioral Segmentation <> K-Means

PREDICTION

Churn <> Logistic Regression

Conversion <> Decision Tree

Customer Lifetime Value <> Random Forest, XG Boost

PERSONALIZATION

A/B Testing <> Multi-Arm Bandit

Timing <> Sequence Analysis

Next Best Action <> Nearest Neighbor

LANGUAGE

Sentiment <> Convolutional Neural Network

Semantic Search <> OWL-Search

Content Extraction <> Support-Vector Machines

Again, any of these marketing tactics could use completely different AI/ML models or non at all depending on what we are trying to solve.

For more on this topic, see my other blog posts on understanding and applying machine learning.

Notebook Thoughts: Behavioral vs Contextual Targeting

In
By Pedro Laboy
Comment

Contextual targeting is done through the use of keywords and categories. For example, we might serve an ad for Nike basketball shoes on the NBA website. Behavioral targeting relies on known user behaviors that have been tracked using cookies and is sometimes enhanced with demographic data. With third-party cookies phasing out, contextual targeting is making a comeback.

Notebook Thoughts: The Foundation of a Great Data Story

By Pedro Laboy
Comment

Telling a great data story begins with framing the what and the how of the questions we would like to answer. We can use our data to compare, diagnose and discover information or insights about relationships/connections, shifts over time and attributes/behaviors. However, the best answers usually are the product of a creative combination of approaches and datasets.
