In a network of connected devices, there are two critical aspects of the system to succeed:

1. Security – with a number of internet-connected devices, securing the network from cyber threats is very important.
2. Privacy - The devices capture business sensitive data that the Organisation has to safeguard to maintain their differentiation.

I've used Federated learning to build anomaly detection models that monitor data quality and cybersecurity – while preserving data privacy.

Federated learning enables Edge devices to collaboratively learn deep learning models but keeping all of the data on the device itself. Instead of moving data to the cloud, the models are trained on the device and only the updates of the model are shared across the network.

Using federated learning gave me the following advantages:

• Ability to build more accurate models faster
• Low latency during inference
• Privacy-preserving
• Improved energy efficiency of the devices

I built deep learning models using tensorflow and deployed using uTensor. uTensor is a light-weight ML inference framework built on Mbed and Tensorflow.

In this talk, I will discuss in detail on how I built federated learning models on the edge devices.

The browser is the most common end-point consumption of deep learning models. It is also the most ubiquitous platform for programming available. The maturity of the client-side JavaScript ecosystem across the deep learning process—Data Frame support (Arrow), WebGL-accelerated learning frameworks (deeplearn.js), declarative interactive visualization (Vega-Lite), etc.—have made it easy to start playing with deep learning in the browser.

Amit Kapoor and Bargava Subramanian lead three live demos of deep learning (DL) for explanations, inference, and training done in the browser, using the emerging client-side JavaScript libraries for DL with three different types of data: tabular, text, and image. They also explain how the ecosystem of tools for DL in the browser might emerge and evolve.

Demonstrations include:

1. Explorable explanations: Explaining the DL model and allowing the users to build intuition on the model helps generate insight. The explorable explanation for a loan default DL model allows the user to explore the feature space and threshold boundaries using interactive visualizations to drive decision making.
2. Model inference: Inference is the most common use case. The browser allows you to bring your DL model to the data and also allows you test how the model works when executed on the edge. The demonstrated comments sentiment application can identify and warn users about the toxicity of your comments as you type in a text box.
3. Rapid prototyping: Training DL models is now possible in the browser itself, if done smartly. The rapid prototyping image classification example allows the user to play with transfer learning to build a model specific for a user-generated image input.

The demos leverage the following libraries in JavaScript:

• Arrow for data loading and type inference
• Facets for exploratory data analysis
• ml.js for traditional machine learning model training and inference
• deeplearn.js for deep learning model training and inference
• Vega and Vega-Lite for interactive dashboards

The working demos will be available on the web and as open source code on GitHub.

The ever-increasing computational capacity has enabled us to acquire, process and analyze larger data-sets and information. We increasingly want to take a data-driven lens to solve business problems. But business problems are inherently 'wicked in nature' - with multiple stakeholders, different problem definition, different solutions interdependence, constraints, amplifying loops etc.

There is no one trick to solve them. What is required is learning a structured approach to problem-solving that can be applied to a large set of these problems. One possible way is to use a Hypotheses Driven Approach - problems definition, scoping, issue identification and hypothesis generation - as a starting point for this. In this workshop, you will learn how to apply a hypothesis-driven approach to any business problem through seven pragmatic steps:

1. Frame
2. Acquire
3. Refine
4. Transform
5. Explore
6. Model
7. Insight

The focus will be to learn the principles through an applied case study and using an iterative and agile methodology.
