Evaluating Models: accuracy = (TP + TN) / total, error rate = 1 minus accuracy, precision = TP / (TP + FP), recall = TP / (TP + FN), F1 = 2PR / (P + R). Modeling: perceptron sum = inputs times weights, added, plus bias. Computer Vision: pixels = width x height, values = pixels x 3 for RGB, 2 to the power 8 = 256 levels. NLP: TFIDF = TF x log10(N / documents containing the word). Modern Age Coders drills them live, Monday and Wednesday at 9:00 PM IST, or one to one. The sheet. Print this part ## What formulas are in class 10 AI? The complete list Twenty formulas and rules cover every calculation in the 417 syllabus. Numbers 1 to 16 can appear in the theory paper; 17 to 20 belong to the practical units. The worked lines underneath use the same figures, so you can check each one. | No. | Formula or rule | Unit | Worked one-liner | | --- | --- | --- | --- | | 1 | Total = TP + FP + FN + TN | 3 | 56 + 14 + 8 + 122 = 200 | | 2 | Accuracy = (TP + TN) / total | 3 | (56 + 122) / 200 = 0.89 | | 3 | Error rate = (FP + FN) / total = 1 - accuracy | 3 | 22 / 200 = 0.11 | | 4 | Precision = TP / (TP + FP) | 3 | 56 / 70 = 0.80 | | 5 | Recall = TP / (TP + FN) | 3 | 56 / 64 = 0.875 | | 6 | F1 = 2 x P x R / (P + R) | 3 | 2 x 0.80 x 0.875 / 1.675 = 0.84 | | 7 | Error = \|actual - predicted\|; error rate = error / actual; accuracy = 1 - error rate | 3 | \|250 - 230\| = 20; 20 / 250 = 0.08; 0.92 | | 8 | Train-test split: rows x share | 3 | 1,200 at 75:25 = 900 train, 300 test | | 9 | Perceptron sum = x1w1 + x2w2 + ... + bias; output 1 if it passes the threshold | 2 | 0.2 + 0 - 0.4 + 0.6 - 0.3 = 0.1, so 1 | | 10 | Pixels = width x height | 5 | 1024 x 768 = 786,432 | | 11 | Values stored = pixels x channels (1 grayscale, 3 RGB) | 5 | 786,432 x 3 = 2,359,296 | | 12 | Levels = 2bits; values run 0 to 2bits - 1 | 5 | 28 = 256, so 0 to 255 | | 13 | Tokens = words + punctuation marks | 6 | "Rain fell, and the match stopped." = 8 | | 14 | Bag of Words vector = count of each dictionary word, in dictionary order | 6 | [ball, bat, run, out] for "bat ball bat run" = [1, 2, 1, 0] | | 15 | TF = count of the word in that document; IDF = N / DF | 6 | N 6, word in 3 documents: IDF = 6 / 3 = 2 | | 16 | TFIDF = TF x log10(N / DF) | 6 | 2 x log10 2 = 0.602 | | 17 | Mean = sum / count | 4, practical | 72 / 6 = 12 | | 18 | Median = middle of the sorted list; even count: average of the two middle values | 4, practical | 9, 9, 11, 12, 14, 17: (11 + 12) / 2 = 11.5 | | 19 | Mode = the most frequent value | 4, practical | 9 appears twice, so 9 | | 20 | Convolution output size = n - k + 1 | 5, practical | 7 x 7 image, 3 x 3 kernel: 5 x 5 | ### Where these formulas earn marks Evaluating Models, worth 10 theory marks, holds six of the twenty and supplies most of the calculation items in a paper. In the latest sample paper the perceptron sum appears only as a one-mark objective item, and pixel or token counts usually do too. TFIDF can come as a short calculation inside an NLP answer. ### Printing it Print the table above on its own: choose Print in your browser, set the range to the first page, and save as PDF if you want a file. It is meant to be read the evening before the paper, after you have written each formula from memory first. Formulas 1 to 8. Evaluating Models ## Accuracy, precision, recall and F1 formula for class 10 AI Accuracy is correct predictions over all predictions; precision is how many of the predicted positives were right; recall is how many of the real positives were caught; F1 combines precision and recall into one score. All four start from the confusion matrix, so build that first. ***One matrix, eight formulas**200 test cases* ``` A plant-disease app checks 200 leaf photos. Really diseased Healthy Predicted sick TP = 56 FP = 14 Predicted fine FN = 8 TN = 122 Accuracy = 178 / 200 = 0.89 Error rate = 22 / 200 = 0.11 Precision = 56 / 70 = 0.80 Recall = 56 / 64 = 0.875 F1 = 1.4 / 1.675 = 0.84 ``` The plain average of precision and recall is 0.8375. F1 is never above the average, and it falls further when the two are far apart. ***The same, checked in Python**run as printed* ``` tp, fp, fn, tn = 56, 14, 8, 122 total = tp + fp + fn + tn p = tp / (tp + fp) r = tp / (tp + fn) print(total, (tp + tn) / total, (fp + fn) / total) print(p, r, round(2 * p * r / (p + r), 2)) # output 200 0.89 0.11 0.8 0.875 0.84 ``` Writing the formulas as code is a good self-test: if the program needs a number you cannot find in the matrix, you have the formula wrong. ### Error for a number prediction (formula 7) When a model predicts a number, not a yes or no, there is no matrix. Error is the gap, ignoring the sign. A bus app predicts a 230-second wait; the bus takes 250. Error = 20 seconds, error rate = 20 / 250 = 0.08, and accuracy for that prediction = 1 - 0.08 = 0.92. ### Train-test split (formula 8) Multiply the rows by each share. 1,200 rows split 75:25 gives 900 to train on and 300 to test on. The test rows must be ones the model never saw in training. ### Which metric the question wants | The costly mistake | Cell | Use | | --- | --- | --- | | Missing a real case (disease, fire, fraud) | FN | Recall | | A false alarm (good mail sent to spam) | FP | Precision | | Both matter, or classes are uneven | FP and FN | F1 | | Both classes common and equal in cost | All four | Accuracy | Ten graded matrix problems are on [confusion matrix numericals](/confusion-matrix-class-10-ai-numericals), and the written answers for the rest of the unit on [evaluating models questions](/cbse-class-10-ai-evaluating-models-questions). Formulas 13 to 16. Natural Language Processing ## TFIDF formula for class 10, with tokens and Bag of Words TFIDF = TF x log10(N / DF), where TF is how often the word appears in this document, N is the number of documents and DF is how many of them contain the word. It is high for a word common in one document and rare in the rest. ### The four NLP rules in order 1. **Tokens.** Split into words and keep each punctuation mark as its own token. "Rain fell, and the match stopped." has six words, a comma and a full stop: 8 tokens. 2. **Bag of Words.** After normalising, list each unique word once as the dictionary, then count. Dictionary [ball, bat, run, out]; "bat ball bat run" becomes [1, 2, 1, 0]. Order follows the dictionary, not the sentence. 3. **TF and IDF.** TF is the raw count from the vector. The CBSE handbook writes IDF as the ratio N / DF, and takes its logarithm in the next step. 4. **TFIDF.** Multiply TF by log10 of that ratio. Base 10, not the natural log: a calculator's ln key gives different numbers that will not match the marking scheme. | N = 6 documents | TF | DF | TFIDF | | --- | --- | --- | --- | | Word in half the documents | 2 | 3 | 2 x log10(6/3) = 0.602 | | Word in only this document | 1 | 1 | log10(6/1) = 0.778 | | Word repeated, in two documents | 4 | 2 | 4 x log10(6/2) = 1.908 | | Word in every document | any | 6 | log10(6/6) = 0 | A word that appears in every document scores 0 however often it occurs, which is why stopwords such as "the" and "is" end up worthless for telling documents apart. The whole pipeline on a three-document corpus, cell by cell, is on [Bag of Words and TFIDF, worked](/bag-of-words-tfidf-class-10-ai); the rest of the unit is on [NLP questions and answers](/cbse-class-10-ai-nlp-questions). Formulas 9 to 12. Modeling and Computer Vision ## Pixel, colour value and perceptron formulas The number of pixels is width times height; the number of values stored is pixels times channels; the perceptron's sum is each input times its weight, added, plus the bias. These are short one-mark calculations, so the only real risk is a slip. ***Formula 9, perceptron**threshold 0* ``` inputs 1 0 1 1 weights 0.2 0.9 -0.4 0.6 bias -0.3 sum = 0.2 + 0 - 0.4 + 0.6 - 0.3 = 0.1 0.1 > 0, so output = 1 ``` An input of 0 cancels its weight, however large: the 0.9 adds nothing. A negative weight subtracts. Forgetting the bias here gives 0.4. ***Formulas 9 to 16, checked**run as printed* ``` import math x = [1, 0, 1, 1] w = [0.2, 0.9, -0.4, 0.6] s = sum(a * b for a, b in zip(x, w)) - 0.3 print(round(s, 2), 1 if s > 0 else 0) print(1024 * 768, 1024 * 768 * 3, 2 ** 8) print(round(2 * math.log10(6 / 3), 3), round(math.log10(6 / 1), 3), math.log10(6 / 6)) # output 0.1 1 786432 2359296 256 0.602 0.778 0.0 ``` The round() matters: without it, Python prints the perceptron sum as 0.09999999999999998, a floating point effect, not a different answer. | Image | Pixels (formula 10) | Values in grayscale | Values in RGB (formula 11) | | --- | --- | --- | --- | | 1024 x 768 | 786,432 | 786,432 | 2,359,296 | For formula 12, an 8-bit value has 28 = 256 possible levels, 0 (black) to 255 (white). The rule works for any bit depth: with 1 bit there are only 2 levels, black and white. The perceptron is drilled on [Unit 2 modeling questions](/cbse-class-10-ai-advanced-modeling-questions) and the image counts on [Unit 5 computer vision questions](/cbse-class-10-ai-computer-vision-questions). Formulas 17 to 20. Practical only ## Statistics and convolution: the formulas for the practical and viva Statistical Data and Advance Python are not in the theory paper, and convolution sits on the practical side of Computer Vision. Examiners ask about these in the lab exam and viva, usually as "what will this program print?". ***Formulas 17 to 19**numpy, run as printed* ``` import numpy as np from statistics import mode d = [14, 9, 11, 9, 17, 12] print(np.mean(d), np.median(d), mode(d)) # output 12.0 11.5 9 ``` Sorted, the list is 9, 9, 11, 12, 14, 17. Six values, so the median is the average of the third and fourth. NumPy prints the mean as 12.0, a decimal, because it always divides as floating point. ***Formula 20, convolution**practical side of Unit 5* ``` output size = n - k + 1 7 x 7 image, 3 x 3 kernel -> 5 x 5 one output cell = multiply and add patch [[1, 2], kernel [[0, 1], [3, 4]] [1, 0]] = 1x0 + 2x1 + 3x1 + 4x0 = 5 ``` The kernel slides one step at a time and never hangs off the edge, which is why the output shrinks by k - 1 in each direction. The eight suggested lab programs, written and explained, are on [Python for CBSE Class 10 AI](/python-for-cbse-class-10-ai). Using the sheet ## AI class 10 cheat sheet: the slips that cost formula marks Students rarely forget a formula outright. They lose marks by feeding it the wrong number. These are the slips we see most often when marking timed numerical sets. | Formula | The slip | The check that catches it | | --- | --- | --- | | Precision and recall | FP and FN swapped, so the two answers trade places | Precision's denominator is the "predicted yes" row; recall's is the "really yes" column | | F1 | Taking the plain average | F1 must be at or below the average; if it is above, redo it | | Accuracy | Dividing by TP + TN only, giving 1 | The denominator is always all four cells | | Error, number model | A negative error | Use the gap without its sign | | Perceptron | Bias left out, or a 0 input still counted | Write one product per input, then the bias, then add | | RGB values | Answering in pixels when values were asked | Underline "pixels" or "values" in the question | | Tokens | Punctuation not counted | Circle every mark before counting | | TFIDF | Natural log, or IDF written upside down as DF / N | Use log10; a word in every document must come out 0 | ### One family per Monday Each Monday class takes one family of formulas, metrics or NLP or images, builds it from the idea up, and works examples on screen with the class calling out each step. ### Fresh numbers on Wednesday The Wednesday class sets a timed numerical set on new figures, marked live, so a remembered answer is no use and only the method scores. ### Formula recall inside mocks Before each full mock, students write this sheet from memory in five minutes. Any formula missing from their version is drilled again that week. One-mark items that use these formulas, with answers and reasons, are on [Class 10 AI MCQ with answers](/cbse-class-10-ai-mcq-questions). Batch or personalised: you choose ## Drill these formulas in the batch, or one to one The same sheet and the same teachers, two formats. The batch works through one formula family a week with classmates racing the same clock; one to one goes straight to the formulas your child keeps getting wrong.

Most are in Evaluating Models: accuracy, error rate, precision, recall and F1 score from a confusion matrix, plus error for number predictions and the train-test split. The others are the perceptron weighted sum, pixel and colour-value counts in Computer Vision, and token counts, Bag of Words and TFIDF in NLP. Mean, median, mode and convolution belong to the practical. ### What is the formula of accuracy, precision and recall? Accuracy = (TP + TN) / (TP + TN + FP + FN). Precision = TP / (TP + FP), the share of predicted positives that were right. Recall = TP / (TP + FN), the share of real positives the model caught. For TP 56, FP 14, FN 8, TN 122 they are 0.89, 0.80 and 0.875. ### What is the F1 score formula in class 10 AI? F1 = 2 x precision x recall / (precision + recall). It balances the two and is pulled toward the lower one. With precision 0.80 and recall 0.875, F1 = 1.4 / 1.675 = 0.84, slightly below their plain average of 0.8375. Never take the simple average. ### What is the TFIDF formula for class 10? TFIDF(W) = TF(W) x log10(N / DF(W)). TF is how many times the word appears in the document, N is the total number of documents, and DF is how many documents contain the word. For a word appearing twice in a document and in 3 of 6 documents, TFIDF = 2 x log10 2 = 0.602. ### Is log base 10 or natural log used for TFIDF in class 10 AI? Base 10. The CBSE handbook for Class 10 AI takes log to base 10 of N divided by DF. Natural log, or the smoothed version software libraries use, gives different numbers that will not match the marking scheme, so use the log button for base 10 when you check your work. ### How do you calculate error in class 10 AI? For a model that predicts a number, error = |actual - predicted|, error rate = error / actual, and accuracy = 1 minus the error rate. A wait predicted as 230 seconds that was really 250 gives error 20, rate 0.08 and accuracy 0.92. For a classifier, error rate = (FP + FN) / total, which is 1 minus accuracy. ### How do you calculate the number of pixels in an image? Multiply width by height in pixels. A 1024 x 768 image has 786,432 pixels. A grayscale image stores one value per pixel, so 786,432 values; an RGB image stores three, one each for red, green and blue, so 2,359,296. With 8 bits per value each one runs from 0 to 255. ### How is the perceptron output calculated? Multiply each input by its weight, add the products, add the bias, then compare with the threshold. Inputs 1, 0, 1, 1 with weights 0.2, 0.9, -0.4, 0.6 and bias -0.3 give 0.1, above a threshold of 0, so the output is 1. In the latest sample paper this appears only as an objective item. ### Is there an AI class 10 cheat sheet I can print? Yes, the numbered table at the top of this page is the cheat sheet: twenty formulas and rules with a worked line each. Use your browser's Print option and save it as a PDF if you want a file. It is for revision at home; nothing can be taken into the board exam hall. ### Are mean, median and mode asked in the class 10 AI theory paper? No. They belong to Statistical Data, which is assessed only in the practical, together with Advance Python. Expect them in the lab exam and viva, often as a NumPy program whose output you must predict, such as the median of an even-length list. ### Do your classes cover all these numericals? Yes. Every formula on this sheet is taught from its idea and then drilled on fresh figures in timed sets, marked live, in the Monday and Wednesday 9:00 PM IST batch or one to one. It is covered by the monthly fee shown on this page, with no admission fee, and the first class is a free demo. Start ## Try a timed numerical set free, with a teacher In the free first class your child solves a short timed set across the formula families with a teacher, then goes through the working line by line on screen.
