How not to miss what’s missing: Survivorship bias in decision making

Survivorship bias is the human tendency of concentrating on the sample that survived (made it past some selection process) and overlooking those that did not . If failures are not considered, then naturally you pay more attention to success. Not only do you fail to recognise that what is missing might have been important, but also you fail to recognise there is any missing information at all.

Locality Sensitive Hashing for Fast Search in High Dimension Data.

In many real-world problems we have to process and analyse large amounts of text data. eg: Text Mining, Spam filtering, Product Recommendation, Online Advertising, etc.. Such data is usually characterised by high dimensionality A common issues across all such problems is to find near neighbours in high dimensional space.We will look at Locality Sensitive Hashing (LSH) a technique that can be used in high dimension data for finding nearest neighbours in large scale databases with near constant look up time.

Explainable AI: Making Sense of the Black Box

Dramatic success in machine learning has led to a surge of Artificial Intelligence (AI) applications. Continued advances in machine learning and compute capacity have led to the development intelligent systems However, the effectiveness of these systems is limited by the machine’s current inability to explain their decisions and actions to human users. Many of the AI applications using ML operate within black boxes, offering little if any discernible insight into how they reach their outcomes

Spatial Data Analysis With Hexagonal Grids

For analyzing large spatial data sets, we need to partition geographic areas into identifiable grid cells. For example, to divide a large region into smaller units for indexing purposes or slice the geographic area into subunits over which we want to summarize a spatial variable. Such grids are usually comprised of either equilateral triangles, squares, or hexagons, as these three polygon shapes are the only ones that can tessellate i.e. cover an area by repeated use of a single shape, without gaps or overlapping
