Assignment - Part A
The revelant files are in Assign_part_A.tar.gz

1)	a,b,c: The isomap for the first three parts have been attached namely 
	Isomap_model_1_7_l2_distance.png, Isomap_model_4_9_l2_distance.png &
	Isomap_model_0_9_l2_distance.png.
	The original isomap.m has been changed to filter out the images with 
	specific labels for MNIST database. The new matlab files generated are
	Isomap_1_7.m,Isomap_4_9.m & Isomap_0_9.m for the three respective parts.

	d: The changes have been done in isomap so as to incorporate the images
	of digits along with the plot.
	The code is in extra_credit_isomap.m & corresponding image is
	extra_credit_3n5.png.

2)	Similar to the first three parts of previous question.


Assignment - Part B
The revelant files are in Assign_part_B.tar.gz

1,2,4)	The residual map have been attached & the answers are mentioned in
	b_part_answers.txt file.

3)	The possible values of all the thetas have been calculated using
	theta.m file.
	The corresponding feasible & non-feasible solutions have also been
	attached using the values derived from theta.m file.
	The steps of calculation & method to derive is mentioned in theta.m
	file as comments.
