Recent Updates

• July 2024: Added a video lecture on hybrid approach (combining clustering and non clustering algorithms to identify anomalies)

• Feb 2023: Added a video lecture on "Explainable AI". This is an emerging and a fascinating area to understand the drivers of outcomes.

• Jan 2023: Added anomaly detection algorithms (Auto Encoders, Boltzmann Machines, Adversarial Networks) using deep learning

• Nov 2022: We all want to know what goes on inside a library. We have explained isolation forest algorithm by taking few data points and identifying anomaly point through manual calculation. A unique approach to explain an algorithm!

• July 2022: AutoML is the new evolution in IT and ML industry. AutoML is about deploying ML without writing any code. Anomaly Detection Using PowerBI has been added. 

• June 2022: A new video lecture on balancing the imbalanced dataset has been added.

Course Description

An anomaly is a data point that doesn’t fit or gel with other data points. Detecting this anomaly point or a set of anomaly points in a process area can be highly beneficial as it can point to potential issues affecting the organization. In fact, anomaly detection has been the most widely adopted area with in the artificial intelligence - machine learning space in the world of business. As a practitioner of AI, I always ask my clients to start off with anomaly detection in their AI journey because anomaly detection can be applied even when data availability is limited.

Anomaly detection can be applied in the following areas:

• Predictive maintenance in the manufacturing industry

• Fraud detection across industries

• Surveillance activities across industries

• Customer Service and retail industries

• Sales

The following will be covered in this program:

• The three types of anomaly detection – time based, non time based and image. Of these, image anomaly is a new frontier for AI. Just like we analyze the numbers, we can now analyze images and identify anomalies.

• Machine learning and deep learning concepts

• Supervised and unsupervised algorithms (DBSCAN, Isolation Forest)

• Image anomaly detection using deep learning techniques

• Scenarios where anomaly detection can be applied

  
  

Anomaly detection is one area that can be applied in any type of business and hence organizations embarking on AI journey normally first explore anomaly detection area. So, as professionals and students, you can also explore this wonderful field!
