# machine learning revision notes

Machine Learning• Herbert Alexander Simon: “Learning is any process by which a system improves performance from experience.”• “Machine Learning is concerned with computer programs that automatically improve their performance through Herbert Simon experience. how to make computers learn from data without being explicitly programmed. The non-max suppression algorithm ensures each object only be detected once. Given a pair of words (i.e. lstm) is it is hard for it to memorise a super long sentence. 10,000)2) we can get a much larger dataset (e.g. The task is translate a sequence to another sequence. the masked self-attention is only allowed to attend to earlier positions of the output sentence. In the above figure, the context is the last 4 words (i.e. Module – 4 Artificial Intelligence Notes pdf (AI notes pdf) Machine -Learning Paradigms, Machine Learning Systems, Deductive Learning, Artificial Neural Networks, Single and Multi- Layer Feed Forward Networks, Advanced Knowledge Representation Techniques, … Machine Learning Notes. In the paper, the used encoding method is: $t_{position,2i}=sin(\frac{pos}{10000^{\frac{2i}{dmodel}}})$$t_{position,2i+1}=cos(\frac{pos}{10000^{\frac{2i}{dmodel}}}). ||W^l||=\sum_{i=1}^{n^{[l-1]}}\sum_{j=1}^{n^{[l]}}W_{ij}^l. Supervised learning algorithms such as Decision tree, neural network, support vector machines (SVM), Bayesian network learning, neares… To address this issue, we can per-define bounding boxes with different shapes. Course Hero, Inc. One way is: In this method, we use a small neural network to map the previous and current information to an attention weight. In which situation we can use transfer learning?Assume:the pre-trained model is for task A and our own model is for task B. Get started. To rollback a release revision, simply create a new release that targets the previous revision and it will become current once again. 1*1, 3*3, 5*5, …). The idea of transfer learning is we can download these pre-trained models and adjust their models to our own problem as shown below. The analysis of various possible performances of the supervised model on the both training and dev set is as shown below. )Now we can compute the gradient of each parameters by simply combine the node gradients:\frac{dJ}{da}=\frac{dJ}{dv}\frac{dv}{da}=3\times1=3$$\frac{dJ}{db}=\frac{dJ}{dv}\frac{dv}{du}\frac{du}{db}=3\times1\times2=6$$\frac{dJ}{dc}=\frac{dJ}{dv}\frac{dv}{du}\frac{du}{dc}=3\times1\times3=9, The gradients is changed a bit by adding \frac{\lambda}{m}W.123Repeat{ W := W - (lambda/m) * W - learning_rate * dJ(W)/dW}, If we have a very deep neural network and we did not initialize weight properly, we may suffer gradients vanishing or exploding problems. If we check the math of \theta and e, actually they play the same role. 0.5), there are some vanishing gradients (e.g. Fig. Usually, the default hyper parameter values are: \beta_1=0.9, \beta_2=0.99 and \epsilon=10^{-8}. These notes are definitely not perfect and messily hand written, but maybe someone will find something useful. Do Ch. Free PDF 2020 Professional AWS-Certified-Machine-Learning-Specialty-KR: AWS Certified Machine Learning - Specialty (AWS-Certified-Machine-Learning-Specialty Korean Version) Exam Revision Plan, Former customers, AWS-Certified-Machine-Learning-Specialty-KR actual exam questions contain the questions which are refined from the real exam test and combined with accurate answers, If you … 1) say we are using layer l’s activation to measure style. Mini-Batch Size:1) if the size is M, the number of examples in the whole train set, the gradient descent is exactly Batch Gradient Descent.2) if the size is 1, it is called Stochastic Gradient Descent. Notation: X_{ij} = number of times word i appears in the context of word j. Revision & Assurance; Rådgivning; KPMG Acor Tax ; Kundehistorier; Machine Learning. In a classification task, usually each instance only have one correct label as show below. By convention, 0.5 is used very often to define as a threshold to judge as whether the predicted bounding box is correct or not. pick the best word at each step). Machine learning (ML) har udviklet sig fra at være en hypet teknologi til en mere moden teknologi, der med fordel kan implementeres, og virksomheder over hele verden investerer massivt i denne teknologi, som er i rivende udvikling. Model-based learning approaches. In addition, every parameter W^{[l]} has the same values. On each mini-batch iteration t: 1) Compute dW, db on the current mini-batch 2) S_{dW}=\beta S_{dW}+(1-\beta)(dW)^2 3) S_{db}=\beta S_{db}+(1-\beta)(db)^2 4) W:=W -\alpha \frac{dW}{\sqrt{S_{dW}}+\epsilon} 5) b:=b-\alpha \frac{db}{\sqrt{S_{db}}+\epsilon}, V_{dW}=0,S_{dW}=0,V_{db}=0,S_{db}=0On each mini-batch iteration t: 1) Compute dW, db on the current mini-batch // Momentum 2) V_{dW}=\beta_1 V_{dW}+(1-\beta_1)dW 3) V_{db}=\beta_1 V_{db}+(1-\beta_1)db // RMSprop 4) S_{dW}=\beta_2 S_{dW}+(1-\beta_2)(dW)^2 5) S_{db}=\beta_2 S_{db}+(1-\beta_2)(db)^2 // Bias Correction 6) V_{dW}^{correct}=\frac{V_{dW}}{1-\beta_1^t} 7) V_{db}^{correct}=\frac{V_{db}}{1-\beta_1^t} 6) S_{dW}^{correct}=\frac{S_{dW}}{1-\beta_2^t} 7) S_{db}^{correct}=\frac{S_{db}}{1-\beta_2^t} // Update Parameters W:=W -\alpha \frac{V_{dW}^{correct}}{\sqrt{S_{dW}^{correct}}+\epsilon} b:=b-\alpha \frac{V_{db}^{correct}}{\sqrt{S_{db}^{correct}}+\epsilon}. into a … A much better method is sampling on the log scale, \alpha=10^r, r\in [-4,0] (0.0001, 0.001, 0.01, 0.1 and 1). The table below could be helpful for you to understand the strategy better. For example,1-\beta=10^rTherefore, \beta=1-10^r$$r\in [-3, -1]$. The pooling layer (e.g. Doing error analysis is very helpful to prioritize next steps for improving the model performance. In order to address this issue, we can use the convolutional implementation of sliding windows (i.e. The matrix is denoted by $E$. machine chapter revision notes - Physics - TopperLearning.com | 2k11klcc When tuning the parameters of the model, we need to decide the priority of them (i.e. classification task, NER etc. Prime Revision comes with over 50,000 past questions and expert explanations spanning from primary to university, revision notes, media, worksheets and more. $w_{ij}$). 1.1 Probability Space When we speak about probability, we often refer to the probability of an event of uncertain The function $d(img1,img2)$ denotes the degree of difference between img1 and img2. Pedro Domingos is a lecturer and professor on machine learning at the University of Washing and Typically the mini-batch size could be 64, 128, 256, etc. arXiv:1809. Another situation we maybe in is:1) we want to build a system for a specific domain, but we only have a few labelled dataset in that domain (e.g. revision - Machine learning adv disadv.pptx - Machine Learning Additional Notes Dr Noorihan Abdul Rahman Advantages disadvantages Machine Learning \u2013, Machine Learning – Classification & Regression (use, Imagine you are calling a large company and end up, talking to their “intelligent computerized assistant,”, pressing 1 then 6, then 7, then entering your account, number, mother’s maiden name, the number of your, house before pressing 3, 5 and 2 and reaching a harried, human being. Machine Learning: Additional Notes Dr Noorihan Abdul Rahman Advantages & disadvantages Machine Learning – 2012. Similarly, if the weight value less than 1.0 (e.g. The reasonable method is:1) all the instances (e.g. The reason I chose to take this exam was to validate my understanding in end-to-end machine learning and developing my knowledge on building reliable and effective architecture for machine learning systems on the cloud. Learning is central to human knowledge and intelligence, and, likewise, it is also essential for building intelligent machines. loss function). Probability Theory Review for Machine Learning Samuel Ieong November 6, 2006 1 Basic Concepts Broadly speaking, probability theory is the mathematical study of uncertainty. Similarly, the average pooling layers returns the average value of all the numbers in that area. We can add a length normalisation term at the beginning:Back to Table of Contents. Using sequence to sequence models is popular in machine translation. at step 2, we keep the sequences: (in, September), (June is), (June visits). Department of Computer Science, 2014-2015, ml, Machine Learning. The symbol $:=$ means the update operation. Department of Computer Science, 2014-2015, ml, Machine Learning. The x-axis is the value of $W^Tx+b$ and y-axis is $p(y=1|x)$. Similarly, for the hidden units range 50-100, picking values in this scale is a good strategy. It will affect the output size. The neural network has $L$ layers. coursera-machine-learning-notes latest Contents: Introduction; Model and Cost Function ; Parameter Learning ... Uva Prakash P Revision cd91656b. I recently passed the Facebook’s Machine Learning Software Engineer (Ph.D.) internship interview. Lectures This course is taught by Nando de Freitas. the dimension of $W$ is the same as the feature vector), the regularization term would be: $||W||_{2}^2=\sum_{j=1}^{dimension}W_{j}^2$. $\mathbf{x}$ are the word embeddings (could be a pre-trained embedding) for each word in the sentence. $dmodel$ is the output dimension size of the encoder in the model. Originally written as a way for me personally to help solidify and document the concepts, In the new loss function, $\frac{\lambda}{2m}||W||_2^2$ is the regularization term and $\lambda$ is the regularization parameter (a hyper parameter). In this post, you got information about some good machine learning slides/presentations (ppt) covering different topics such as an introduction to machine learning, neural networks, supervised learning, deep learning etc. There are different ways to compute the attention. central role in machine learning, as the design of learning algorithms often relies on proba-bilistic assumption of the data. The notes included here will be displayed in the release notes on the developer portal. Understanding and learning these summary notes alone got me a distinction in my exams, so hopefully they're mostly correct and somewhat thorough. Then the Bleu Score on bigrams can be computed as: The above equation can be used to compute unigram, bigram or any-gram Bleu scores. If the computation resources are sufficient, the most simple way is training models with various parameter values parallel. The learning rates of each epoch are: Of course, there are also some other learning rate decay methods. Therefore, when making predictions, the model will not rely on any one feature. the last two layers). ML is one of the most exciting technologies that one would have ever come across. ExamplePick a sentence from the dev set and check our model: Sentence: Jane visite l’Afrique en septembre.Translation from Human: Jane visits Africa in September. Set delete_after_analyze to yes so that downloaded images are removed after analysis. $0.5^L$) somewhere. So these pairs are negative examples (it is ok if the real target word is selected as a negative example by chance). $[\mathbf{t_1,t_2,t_3}]$ are the position encodings of each word. It’s a rich condensed read. These are used in the multi-head attention sublayer (also named encoder-decoder attention). Then apply it to the target picture step by step: The problem is the computation cost (compute sequencently). The equation of the multiplied term is $\sqrt{\frac{1}{n^{[l-1]}}}$. $i$ is the element position of the position encoding. Fitting global dynamics models (“model-based RL”) b. Slides for Spring School "Structural Inference in Statistics," Sylt, Germany. The output of our model: The cat the cat on the cat. known as the ‘logistic function’ instead of a linear function. In this situation, it is a good idea that estimating reasonable values of $\mu$ and $delta$ by using exponentially weighted average across mini-batches. context word an another word), and a label (i.e. $m$ is the number of train instances. Find way to make the learning rate adaptive could be a good idea. I found that the best way to discover and get a handle on the basic concepts in machine learning is to review the introduction chapters to machine learning textbooks and to watch the videos from the first model in online courses. The computation could be converted into the computation graph below: Based on the graph above, it is clear that the gradient of parameters are: $\frac{dJ}{da}=\frac{dJ}{dv}\frac{dv}{da}$, $\frac{dJ}{db}=\frac{dJ}{dv}\frac{dv}{du}\frac{du}{db}$, $\frac{dJ}{dc}=\frac{dJ}{dv}\frac{dv}{du}\frac{du}{dc}$.Computing the gradients of each node is easy as shown below. For a classification task, the human classification error is supposed to be around 0%. Videos. The previous methods can only detect one object in one cell. You may can also consider combine the style loss of different layers. ($y^*$)Output of the Algorithm (our model): Jane visited Africa last September. Please be free to use Ctrl+F to search any key words interested you. (Usually increasing beam search width will not hurt the performance). The figure below may provide you some insights to understand the idea. Particularly, ECMarker is built on the integration of semi- and discriminative- restricted Boltzmann machines, a neural network model for classification allowing … As shown in the below figure, the (orange juice 1) is a positive example as the word juice is the real target word of orange. BUT it is not a good idea. Suppose the inputs are two dimensional, $X = [X_1, X_2]$. For each grid cell, we can get 2 (number of anchor boxes) predicted bounding boxes. Negative Picture: another picture of not the same person in the anchor picture. UCL MSc Computational Statistics and Machine Learning. 2015. Firstly, making a manually error analysis to try to understand what is the difference between our training set and dev/test set. the output of the top encoder is transformed into attention vectors $K$ and $V$. Given the feature vector of an instance $x$, the output of logistic regression model is $p(y=1|x)$. By repeating the above error analysis process on multiple instances in the dev set, we can get the following table:Based on the table, we can figure out what faction of errors are due to beam search/RNN. If we have $P_1$, $P_2$, $P_3$ and $P_4$, we can combined as following: The brevity penalty penalises short translation. When tuning hyper parameters, it is necessary to try various possible values. Find top revision tools that will help you be super productive and revise like a pro! ), but also the running time, we can design a single number evaluation metric to evaluate our model. Bert: Pre-training of deep bidirectional transformers for language understanding. In momentum, $V_{dW}$ is the information of the previous gradients history. French: Le chat est sur le tapis.Reference1: The cat is on the mat.Reference2: There is a cat on the mat. This preview shows page 1 - 8 out of 26 pages. a grid cell that contains the object’s mid point, a anchor box for the grid cell with highest $IOU$. The idea of filter is if it is useful in one part of the input, probably it is also useful for another part of the input. Generally, if the filter size is f*f, the input is n*n, stride=s, then the final output size is:$(\lfloor \frac{n+2p-f}{s} \rfloor+1) \times (\lfloor \frac{n+2p-f}{s} \rfloor+1)$. If $W$ is a matrix of parameters(weights), $\frac{dJ(W)}{dW}$ would be a matrix of gradients of each parameter (i.e. The original $\beta$ is from the parameter of exponentially weighted averages. For example (as shown in the above picture). Moreover, each output value of a convolutional layer output values only depends on a small number of inputs. Do forward propagation on the t-th batch examples; Compute the cost on the t-th batch examples; Do backward propagation on the t-th batch examples to compute gradients and update parameters. $\frac{dJ(W)}{dW}$ is the gradient of parameter $W$. For simplicity, the parameter $b^{[l]}$ for each layer is 0 and all the activation functions are $g(z)=z$. Alternatively, we can also specify the maximal running time we can accept:$max: accuracy$$subject: RunningTime <= 100ms. As for the number of parameters, for a filter, there are 27(parameters of filter) +1 (bias) =28 parameters totally. The easiest way is just combine the two datasets and shuffle it. In order to check whether we have the data mismatch problem, we should randomly pick up a subset of training set as a validation set named train-dev dataset. Therefore, if a hidden layer has n units and the probability is p, around p \times n units will be activated and around (1-p)\times n units will be shut off. Jointly maximize the likelihood of the forward and backward directions: LSTMs are used to model the forward and backward language models. In order to reduce the computation, negative sampling is decent solution. Therefore, the final word embedding of a word is: Forward language model: Given a sequence of N tokens, (t_1,t_2,…,t_N), a forward language model compute the probability of the sequence by modelling the probability of t_k given the history, i.e.. Bidirectional language model: it combines both a forward and backward language model. NXP’s i.MX 8M Plus applications processor enables machine learning and intelligent vision for consumer applications and the industrial edge. These notes attempt to cover the basics of probability theory at a level appropriate for CS 229. As for the performance of model, sometimes it could work better than that of human. J(W) is the loss function of our model. I'm not sure if this kind of stuff is appropriate to share here, but I recently scanned all my revision notes from my masters in stats+ML and put it on my GitHub here.. The inputs normalization is as follows. Using input normalization could make training faster. In the equation, l is the l^{th} layer and n^{[l]} is the number of hidden units in layer l. Using the convolutional implementation, we do not need to compute the results sequencently. The details of batch normalization in each layer l is: \mu=\frac{1}{m}\sum Z^{(i)}$$\delta^2=\frac{1}{m}\sum (Z^{(i)}-\mu)$$Z^{(i)}_{normalized}=\alpha \frac{Z^{(i)}\mu}{\sqrt{\delta^2}+\epsilon} +\beta$. But it is easy for us to collect a lot of instances (e.g. ($\hat{y}$). 200,000) from another similar domain. The outputs are the probabilities of each class. The $UNK$ is a special work which represents unknown words. Because the weight value $1.5>1$, we will get $1.5^L$ in some elements which is explosive. Linear Regression Introduction. Therefore, the L2 regularization term would be: $\frac{\lambda}{2m}\sum_{l=1}^L||W^l||_2^2$. If we set stride=1 and padding=1, we can get the output with the same size as input. ), For example, when we initialize the parameter $W$, we time a small value (i.e. Similarly, if the input is a volume which has 3 dimensions, we can also have a 3D filter. But there would be a problem just learning the above loss function. 2) define the style of an image as correlation between activations across channels. Gradient Descent # Vanilla update w +=-learning_rate * dw. The Artiﬁcal Intelligence View. I am a parent. Become your most unstoppable self. Therefore, at each step, we only keep the top 3 best prediction sequences. Apart from the abovementioned aspect, how to select the hyper parameter value wisely is also very important. In fact, we also apply activation functions on a convolutional layer such as the Relu activation function. It plays a central role in machine learning, as the design of learning algorithms often relies on proba-bilistic assumption of the data. The learning algorithm (i.e. Let’s say, finally we found 6% instances were labelled incorrectly. NEW SAMPLE INFORMATIVE SPEECH TEMPLATE.docx, UCS551 Chapter 5 - Machine Learning (Intro).pptx, The University of Lahore - Defence Road Campus, Lahore, The University of Lahore - Defence Road Campus, Lahore • CS MISC, Copyright © 2020. This may cause side effects - data mismatch problem. whether or not high level texture components tend to occur or not occur together). Based on the abovementioned idea, we could time the weights with a term related to the number of hidden units. Obviously, we are updating the value of parameter $W$.
