left and right hand sides are different why?












2












$begingroup$


Let's say I have 50 coins total.



I give 20 coins to my friend



I am left with 30



Then I give 15 again



I am left with 15



Again I give 9



I am left with 6



Again I give 6



I am left with 0



When I sum them up back what I had left each time: 0+6+15+30 = 51



But I had only 50 rupees.



And when I calculated what I gave each time it is 6+9+15+20 = 50



And they both are different. Why they are different?

          $begingroup$

          Because you should




          actually add what you give out, not you have left each time




          which is




          20+15+9+6=50




          Second question:




          imagine this. you have 10 dollars. you spend them one by one. by adding what you have left each time you get 9+8+7+6+5+4+3+2+1=45 dollars. but you actually have 10 dollars in the beginning, not 45.

          Tabula Rosettana

          Image
          Tabula multilinguis Rosettana in Museo Britannico ostenditur. Tabula Rosettana, [1] etiam titulo OGIS 90 agnita, est stela decreto de rebus sacris in Aegypto anno 196 a.C.n. lato inscripta. Tabula iuxta Rosettam Aegypti, urbem in delta Nili et ad oram maris Mediterranei iacentem, anno 1799 a milite Francico reperta est. Inventio stelae, linguis duabus scripturisque tribus inscriptae, eruditis Instituti Aegypti statim nuntiata est; ibi enim iussu imperatoris Napoleonis eruditi omnium scientiarum (sub aegide Commissionis Scientiarum et Artium) properaverant cum expeditione Francica. Qua a Britannis mox debellata, tabula Rosettana Londinium missa hodie apud Museum Britannicum iacet.

          How to label and detect the document text images

          Image
          1 $begingroup$ This is what I mean as document text image: I want to label the texts in image as separate blocks and my model should detect these labels as classes. NOTE: This is how the end result should be like: The labels like Block 1, Block 2, Block 3,.. should be Logo, Title, Date,.. Others, etc. Work done: First approach : I tried to implement this method via Object Detection, it didn't work. It didn't even detect any text. Second approach : Then I tried it using PixelLink. As this model is build for scene text detection, it detected each and every text in the image. But this method can detect multiple lines of text if the threshold values are increased. But I have no idea how do I add labels to the text blocks. PIXEL_CLS_WEIGHT_all_ones = 'PIXEL_CLS_WEIGHT_all_ones' PIXEL_C...
