Write a detail note on self organizing map

Expert Solution

A self-organizing map (SOM) is a type of artificial neural network that uses unsupervised learning to build a two-dimensional map of a problem space. They are also known as a self-organizing feature map (SOFM) or a Kohonen map. It belongs to the category of competitive learning networks. The Self-Organizing Map is based on unsupervised learning, which means that no human intervention is needed during the learning and that little needs to be known about the characteristics of the input data.

A self-organizing map can generate a visual representation of data on a hexagonal or rectangular grid. Applications include meteorology, oceanography, project prioritization, and oil and gas exploration.

The Self organising map algorithm is based on unsupervised, competitive learning. It provides a topology preserving mapping from the high dimensional space to map units. Map units, or neurons, usually form a two-dimensional lattice and thus the mapping is a mapping from high dimensional space onto a plane.

Write down the equation of a utility function and construct an indifference map that corresponds to each of the following case: -Bob always consumes beer and pizza in fixed proportions. Specifically, If Bob has 1 pizza, he consumes precisely 2 beers and additional beers represent no additional utility for Bob. Similarly, if Bob has 2 beers, he consumes precisely 1 pizza and additional pizzas represent no additional utility for Bob. In addition, when Bob has 4 pizzas and 10 beers,...

Write a Python application to find the longest ‘A’ path on a map of capital (uppercase) letters. The map is represented as a matrix (2-dimensional list) of capital letters. Starting from any point, you can go left, right, up and down (but not diagonally). A path is defined as the unbroken sequence of letters that only covers the spots with the letter A. The length of the A path is defined as the number of ‘A’s on the path. Your...
