Euclides (hic falso 'Megarensis' nominatus) ab Iusto Gandavino ca. 1474 depictus
Euclides Alexandrinus (Graece: Εὐκλείδης) est clarissimus mathematicus antiquus, qui saeculo IV a.C.n. Alexandriae Ptolemaeo I regnante (304–293 a.C.n.) floruit. Plurimum innotuit opere magno, quod Elementa (Στοιχεῖα) inscribitur. Hoc opus in tredecim consistit libris, quorum primi quattuor theoremata geometriae planae, libri quinti et sexti theoriam proportionum, libri septemi usque ad IX theoriam arithmeticam per formas geometricas descriptam, ultimi denique tres libri geometriam solidam continent.
Opera |
Praeter Elementa Euclides nonnullos libros minores scripsit:
- Optica
Catoptrica, opera geometriae in visum phaenomenorum luminosorum adhibitae
Phaenomena, descriptionem geometricam sphaerae caelestis continens
- Sectio canonis (Graece: Κατατομὴ Κανόνος), mathematicam musicae theoriam continens
Data, de quantitatibus vel aliis notionibus datis in problematis geometricis
- ceteros plures partim Arabice tantum conservatos, partim ab aliis auctoribus citatos

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. Textus Graecus cito lectus interpretationi textuum Aegyptiorum (in formis hieroglyphica et demotica expressorum) gradatim adiuvit. Denique textum plene interpretatus est Ioannes Franciscus Champollion. Ab opere eruditorum cumulativo coepit hodiernus scripturae hieroglyphicae linguaeque Aegyptiae a...

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...

I have this LSTM model model = Sequential() model.add(Masking(mask_value=0, input_shape=(timesteps, features))) model.add(LSTM(100, dropout=0.2, recurrent_dropout=0.2, return_sequences=False)) model.add(Dense(features, activation='softmax')) model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy']) and shapes X_train (21, 11, 5), y_train (21, 5) . Each timestep is represented by 5 features and return_sequences is set to False because I want to predict one 5D array (the next timestep) for each input sequence of 11 timesteps. I get the error ValueError: y_true and y_pred have different number of output (5!=1) If I reshape the data as X_train (21, 11, 5), y_train (21, 1, 5) instead I get the error ValueError: Inva...
