CIS006-2 Random Search Optimisation And Meta Learning Assignment 2 – UK
What am I required to do in this assignment?
Task :-
Students will use one or more strategies such as: (1) Random Search (2) Meta Learning (3) Adaptive Boosting or (4) Cascade Correlation to optimise the structure and parameters of Artificial Neural Networks (ANNs) on a given benchmark problem. Such optimisation is required to maximise the recognition accuracy of ANNs designed for solving biometric tasks. In practice the optimal structure and parameters of ANNs are difficult to find because of the needs of multiple experiments with the different numbers of principal components hidden neurons learning rate and types of gradient algorithms.
COVID related alternatives
There are alternatives which students can find interesting within the unit scope.
Method and Technology :-
Students will attempt to optimise ANNs which were manually designed in Assignment 1 To achieve the goal students will apply one or more optimisation strategies with different parameters The following examples: i Random Search ii Meta Learning iii Adaptive Boosting as well as iv MATLAB search strategies which are discussed in the unit tutorials. Advanced students can use Python MATLAB or R to optimise Deep Learning Convolutional Networks or Conventional ANNs.The 2nd assignment is an extension of the 1st and so they are dependent and could be compared on the same data. The above listed strategies are new approaches to the optimisation task supported by many other online tutorials.
Example of Optimisation Solution
An example of an ANN optimisation in MATLAB is presented by a conference paper published by the Computer Science students in Springer proceedings. Other solutions will be discussed.
Evaluation
Group managers will rank individual solutions within their groups. The designed solutions will be evaluated on a validation test data set in terms of the recognition accuracy. Individual members will describe and explain their experiments with different parameters of optimisation methods.
Reports :-
Similar to Assignment 1 students will describe their experiments in individual reports to be submitted via BREO. A report template could be recommended. A similarity level of reports will be evaluated via BREO Turnitin.
Is there a size limit?
2000 words on average

What do I need to do to pass?
Google Colab is a recommended platform, however advanced students can use other development environments
1. Identify one or more parameters of an optimisation strategy which can be implemented (15%)
2.Demonstrate the results obtained with a chosen optimisation strategy (15%)
3.Describe the main factors which influence the recognition accuracy (12%)
4.In total 42% to pass
How do I produce high quality work that merits a good grade?
1.Find a set of parameters required within an optimisation strategy
2.Explain how the optimisation parameters influence the results
3.Run experiments in order to verify a designed solution on a data bench mark
4.Analyse and compare the results of experiments with different optimisation parameters
5.Compare the accuracy between the 1st and 2nd assignments using the same data and an advanced technique
6.Describe how to improve the 1st assignment by using a search optimisation or other technique
7.Students could optionally record a 5-min video demonstration of developed artefact (and then include a video link in the appendix to report)
How does assignment relate to what we are doing in scheduled sessions?
Search and Optimisation algorithms as well as use cases will be considered during lectures and tutorials.
