Cracking in Concrete

Definition: a complete or incomplete separation of either concrete or masonry into two or more parts produced by breaking or fracturing - ACI Concrete Terminology

Concrete is the most important material in civil engineering. Concrete provides structures with strength, rigidity, and resilience from deformation. These characteristics, however, result in concrete structures lacking the flexibility to move in response to environmental or volume changes. Cracking is usually the first sign of distress in concrete. It is, however, possible for deterioration to exist before cracks appear. Cracking can occur in both hardened and fresh, or plastic, concrete as a result of volume changes and repeated loading. [Source of Information: giatecscientific]

Problem Statement

Imagine you being a Civil Engineer with knowledge of Data Science and Machine Learning too. You are asked by your state/local government to find out all the cracked concrete and replace it with a new one. Now, with a good knowledge of Machine Learning / Deep Learning, you take a decision to build a system that would alert you when a cracked concrete is detected.

Objective

Build a Machine Learning or Deep Learning model that would help you detect the cracked concrete.

Evaluation Criteria

Submissions are evaluated using Accuracy Score.

How do we do it?

Once we release the data, anyone can download it, build a model, and make a submission. We give competitors a set of data (training data), with both the independent and dependent variables.

We also release another set of data (test dataset) with just the independent variables, and we hide the dependent variable that corresponds with this set. You submit the predicted values of the dependent variable for this set and we compare it against the actual values.

The predictions are evaluated based on the evaluation metric defined in the datathon.
