    (1). All the images corresponding to the images are in the folder 'images_AI_assignment2', with appropriate names.

    (2). All the codes been used are in the directory 'codes'.

	-we have seperated and modified the isomap code for each part of the question

    (3). The explanation part of the assignment is written in the 'Answers.txt' file


    For answers to A part of the assignment:

	
	(A1)-to get the isomap corresponding to 4 & 9 (Euclidean)functions need to be called are.

		>>[data,labels]=loadDigits(2000,'test');

		>>c=get49(data,labels);

		>>dis49=L2_distance(c,c);

		>>Isomap49(dis49,c,'k',7);
	

	(A1)-to get the isomap corresponding to 1 & 7 (Euclidean)functions need to be called are.

		>>[data,labels]=loadDigits(2000,'test');

		>>a=get17(data,labels);

		>>dis17=L2_distance(a,a);

		>>Isomap17(dis17,a,'k',7);


	(A1)-to get the isomap corresponding to all digits (Euclidean)functions need to be called are.

		>>[data,labels]=loadDigits(2000,'test');

		>>d=L2_distance(data,data);

		>>Isomap(d,data,labels,'k',7);


	(A2)-to get the isomap corresponding to 4 & 9 (tangential)functions need to be called are.

		>>[data,labels]=loadDigits(2000,'test');

		>>c=get49(data,labels);

		>>dist49=tangent_d(c,c);

		>>Isomap49tang(dist49,c,'k',7);

		>>[data,labels]=loadDigits(2000,'test');

		>>a=get17(data,labels);

		>>dist17=tangent_d(a,a);

		>>Isomap17tang(dist17,a,'k',7);


	(A2)-to get the isomap corresponding to all digits (tangential)functions need to be called are.

		>>[data,labels]=loadDigits(2000,'test');

		>>dt=tangent_d(data,data);

		>>Isomaptang(dt,data,labels,'k',7);





    For answers to the B part of the questions:


	(B1)-to get the isomap data and the residual variance curve the following commands been used.

		>>[data_B1, namesB1] = loadImageData('nao200', 'jpg');

		>>data_B1=double(data_B1)

		>>B1=L2_distance(data_B1,data_B1);

		>>Isomap_normal(B1,'k',7);


	(B2)-to get the isomap data and the residual variance curve the following commands been used.

		>>[data_B2, namesB2] = loadImageData('box_random', 'jpg');

		>>data_B2=double(data_B2)

		>>B2=L2_distance(data_B2,data_B2);

		>>Isomap_normal(B2,'k',7);


	(B4)-to get the isomap data and the residual variance curve the following commands been used.

		>>[data_B4, namesB4] = loadImageData('box1', 'jpg');

		>>data_B4=double(data_B4)

		>>B4=L2_distance(data_B4,data_B4);

		>>Isomap_normal(B4,'k',7);
