It is a long process and one need to spend few years over 2000 hours in AI and another 2000 hours in Deep Learning to get good at it. It is highly mathematical oriented and parts are driven by biology and those who do not know foundations of Physiology will find great difficulty in relating real world problems in mechanisation.Artificial Intelligence is a broad subject and an old one with research has been done over 60 years based on machines, based on brain it over 100 years old. Operations of a machine mimic some skills of humans have been defined by Artificial Intelligence as first proposed by John McCarthy in 1956. His published a paper called “SOME PHILOSOPHICAL PROBLEMS FROM THE STANDPOINT OF ARTIFICIAL INTELLIGENCE” in 1969, while working in computer science dept., of famous Standford University in Silicon Valley, CA, USA. Source: https://www.csee.umbc.edu/courses/771/spring03/papers/mcchay69.pdfHe said, “ We may regard the subject of AI as beginning with Turing's article Computing Machinery and Intelligence (Turing 1950) and with Shannon's (1950) discussion of howa machine might be programmed to playchess.”Basic view of intelligence is epistemological and the heuristic way according to Macarthy. The epistemological part is the representation of the world in such a form that the solution of problems follows from the facts expressed in the representation. The heuristic part is the mechanism that on the basis of the information solves the problem and decides what to do. Most of the work in articial intelligence so far can be regarded as devoted to the heuristic part of the problem.Source: Minsky, M. (1961), “Steps towards Artificial Intelligence”, Proceedings of the I.R.E., 49, 8-30.Alan Turing created a machine that just can plug in a electrical socket run forever off course doing some really came later but Turning test are critcial in AI.

Propose a solution and develop a prototype and test itHow does an eye work lot more complex than an camera. How do photos process in a smart phone is also complex?Storing in a creative way and process thru a microprocessor is the focus now. But select a specific photo is not still there but get photos by date or by group is only possibility now. In Brian, think an incident and close eyes you pictures, HOW? Hypothalamus and Neocortex work synchronizely in CNS to produce is what baffling many scientists. There “ thousands of processes we do how” is the study of AI.There are 7 million rods and more than a million cones in each besides Ganglion Cells, Bipolar cells etc to decide our view into retina eventually store in cortex.The process of getting information, process and transmit is done in any nerve called “Synapse” with Dendrite (with small wires) , Nucleus and Axon (a long part)Lynn Conway, a famous mainframe designer at IBM, also worked at XEROX at Palo Alto and Carver Mead a professor at Cal Tech, a top five research universities i. USA, created AI based eye in latest 1980s but it can only less than 20 percent of our eye. There are the “First” authors VLSI, especially Conway preached MIT, Berkeley, UCLA, etc to teach VLSI. Then came expert systems, neural networks, fuzzy logic etc.Introduction to VLSI Systems by Carver Mead & Lynn Conway, Addison-Wesley Longman Publishing Co., Inc. Boston, MA, USA ©1979ISBN:0201043580This book was cited over 4400 in Research.How you make a machine to bring coffee from a flask. Open the top cup by rotating clockwise, get a mug, bend flask, pour Coffee, close lid, navigates where you are? All thus done now so called Robotics but not cheap.How do we understand this simply process but a complex system is THE foundation of AI.There are variety coffee machines made in USA, while I was there for different dose if coffee or sugar or temperatures of for Indians mix milk. How can AI can be used, a simple way is Fuzzy logic (FL). At a machine, a person takes a coffee he can say coffee need darker or more temp or less sugar. The machine with processor and memory can create new set of values for three variables of coffee, sugar, temperature, a fuzzy way of doing AI. In 1964, Lotfi Zadeh developed FL.Honey Bees collect honey through flowers using earth magnetic field. But how do they find, get back, communicate and establish a nest just like a group of human develop a family. Few algorithms were developed on this and Artificial Neural Networkes were created.Read about Marvin Lee Minsky (August 9, 1927 – January 24, 2016) was an American cognitive scientist concerned largely with research of artificial intelligence (AI)A great book by Gerald M. Edelman, “A Remembered Present” who won a Noble Prize in Medicine.Ex: “Creating and simulating neural networks in the honeybee brain using a graphical toolchai”, http://greenbrain.group.shef.ac.uk/wp-content/uploads/2013/11/SFN_2013_GB.pdfDeep Blue, a super computer made by IBM, almost beat any Grand Master, Vishwanth Anand played many times, list only few times, a great example of a billion dollar AI investment on research.“Artificial Intelligence and Human Thinking “ by Robert Kowalski, Imperial College London United Kingdom [email protected]. According to Kowalski, “Research in AI has built upon the tools and techniques of many different disciplines, including formal logic, probability theory, decision theory, management science, linguistics and philosophy. However, the application of these disciplines in AI has necessitated the development of many enhancements and extensions. Among the most powerful of these are the methods of computational logic. I will argue that computational logic, embedded in an agent cycle, combines and improves upon both traditional logic and classical decision theory. I will also argue that many of its methods can be used, not only in AI, but also in ordinary life, to help people improve their own human intelligence without the assistance of computers.” According him that Abductive Logic Programming form of compututational Logic embeds agent cycle shows in the following figure.A basic paper in AI can be easily accessed throughj Reasearch Gate: Artificial Intelligence by Mariam Khaled Alsedrah, The American University of the Middle East, December 2017. She told that AI works based on several models such as: Ant Colony Algorithm, Immune Algorithm, Fuzzy Algorithm, Decision Tree, Genetic Algorithm, Particle Swarm Algorithm, Neural Network, and Deep Learning.Neural networks deal with higher millions neurons that process information in CNS if Brain so called nerves. They are an essential part of AI nowadays. From a synaptic weight to summation, to back propagation to networking is the complex maze of ANN. I worked on two ANN projects at Motorola in CMOS VLSI. First chip has 1,15,200 logic gates and 2nd chip had over 1 million logic gates and fabricated 1994.A Hopfield network is a form of recurrent artificial neural network popularized by John Hopfield in 1982 and serve as content-addressable ("associative") memory systems with binary threshold nodes.Areas of of AI1. Language understanding: The ability to "know and understand" while responding to the natural language, in English by SIRI in Apple iPhone. AI has a significant research and applications in processing spoken language or written language or mother tounge: Language Translation , Semantics Processing, Vocabulary building of specific individual, Information Retrieval, etc.2. Problem solving: Formulate a problem in a specific situation, develope a solution meeting with a criteria, identify what new information is needed to formulate and the barriers to be identified to obtain it. Inductive and Deductive logic, Resolution-Based Theorem Proving and Heuristic Search.3. Perception: he Pattern recognistion is critical and models have to use and need to develop further to analyze a sensed scene and how accurately it represents the process of living mind.4.

It comprises multiple hidden layers of artificial neural networks. The deep learning methodology applies nonlinear transformations and model abstractions of high level in large databases. The recent advancements in deep learning architec-tures within numerous fields have already provided significant contributions in artificial intelligence. This article presents a state of the art survey on the contributions and the novel applications of deep learning. The following review chronologically presents how and in what major applications deep learning algorithms have been utilized. Furthermore, the superior and beneficial of the deep learning methodology and its hierarchy in layers and nonlinear operations are presented and compared with the more conventional algorithms in the common applications. The state of the art survey further provides a general overview on the novel concept and the ever-increasing advantages and popularity of deep learning.1. Spherical CNNs Researchers at the University of Amsterdam have developed a variation of convolution neural networks (CNN) known as Spherical CNNs. These CNNs work with images which are spherical in shape (3D). For example, images from drones and autonomous cars generally cover many directions and are three-dimensional. Regular CNNs are applicable only to two-dimensional images, and imposing 3D features from images mentioned in this example may literally fail in a DL model. This is where Spherical CNNs were envisioned. In the paper, the researchers conceptualise spherical features with the help of the Fourier Theorem, as well as an algorithm called Fast Fourier Transform. Once developed, they test the CNNs with a 3D model and check for accuracy and effectiveness.The concept of Spherical CNNs is still at a nascent stage. With this study, it will definitely propel the way CNNs are perceived and used. You can read the paper here.2. Can Recurrent Neural Networks Warp Time? Not just ML and AI researchers, even sci-fi enthusiasts can quench their curiosity about time travel, if they possess a strong grasp of concepts like neural networks. In a research paper published by Corentin Tallec, researcher at University of Paris-Sud, and Yann Ollivier, researcher at Facebook AI, they explore the possibility of time warping through recurrent neural networks such as Gated Recurrent Units (GRUs) and Long Short Term Memory (LSTM) networks. The self-learning capabilities present in these models are analysed. The authors have come up with a new concept called ‘Chrono Initialisation’ that derives information from gate biases of LSTM and GRUs. This interesting paper can be read here.3. Learning How To Explain Neural Networks: PatternNet And PatternAttribution We are yet to fully understand why neural networks work exactly in a particular way. Complex ML systems have intricate details which sometimes astonish researchers. Even though there are systems which decode neural networks, it is difficult at times to establish relationships in DL models. In this paper, scholars at Technical University in association with researchers at Google Brain, present two techniques called PatternNet and PatternAttribution which explain linear models. The paper discusses a host of previously established factors such as signal estimators, gradients and saliency maps among others. You can read the paper here.4. Lifelong Learning With Dynamically Expandable Networks: Lifelong learning was a concept first conceived by Sebastian Thrun in his book Learning to Learn. He offered a different perspective of the conventional ML. Instead of ML algorithms learning one single task, he emphasises on machines taking a lifelong approach wherein they learn a variety of tasks over time. Based on this, researchers from KAIST and Ulsan National Institute of Science and Technology developed a novel deep network architecture called Dynamically Expandable Network (DEN) which can dynamically adjust its network capacity for a series of tasks along with requisite knowledge-sharing between them. DEN has been tested on public datasets such as MNIST, CIFAR-100 and AWA for accuracy and efficiency. It was evaluated for factors including selective retraining, network expansion and network timestamping (split/duplication). This novel technique can be read here.5. Wasserstein Auto-Encoders: Autoencoders are neural networks which are used for dimensionality reduction and are popularly used for generative learning models. One particular type of autoencoder which has found most applications in image and text recognition space is variational autoencoder (VAE). Now, scholars from Max Planck Institute for Intelligent Systems, Germany, in collaboration with scientists from Google Brain have come up with the Wasserstein Autoencoder (WAE) which utilises Wasserstein distance in any generative model. In the study, the aim was to reduce optimal transport cost function in the model distribution all along the formulation of this autoencoder. After testing, WAE proved to be more stable than other autoencoders such as VAE with lesser architectural complexity. This is a great improvement in autoencoder architecture. Readers can go through the paper here.Endnote: All of these papers present a unique perspective in the advancements in deep learning. The novel methods also provide a diverse avenue for DL research. Machine learning and artificial intelligence enthusiasts can gain a lot from them when it comes to latest techniques developed in research. By the research of Abhishek Sharma in data science.

How to prepare for CAT 2019With another 9 months left for CAT 2019 (expected to be held towards the end of November’19), how should you start your preparation? We know that the CAT tests skills in three areas – Quantitative Aptitude, Logical reasoning & Data Interpretation, and Verbal Ability.Thus, to excel in this test, you need to devote time equally to each of the three areas. How to effectively do that is what we will discuss.Take stock of the situationThose who have already started preparing for CAT 2019 sometime back, would be aware of exactly what sort of skills are required to excel in these three areas. They would also be aware about which area they are particularly weak in. Needless to say, you need to devote the major part of your preparation to overcome your weaknesses.However, those who have decided to start just now for CAT 2019, don’t worry! You are not late in starting your preparations. But, first you need to understand what you need to study, isn’t it?To do that, take up any past years’ question papers – preferably CAT 2017 or CAT 2018, and go through the questions to have a fair bit of idea as to what you can expect in the exam. It is worthwhile to note that all other exams, like XAT, NMAT, SNAP, IIFT have a very similar ‘syllabus’ as that of CAT.Take the first few stepsOnce you are acquainted with the syllabus, you are ready to start your prep. But how? The preparation strategy for each section is different. Let us discuss one by one:Verbal AbilityYou should typically start doing the following activities simultaneously for your CAT 2019 preparation:Start reading a English newspaper – read all the relevant news articles and the editorials. The benefits are four-fold:You get to know about all relevant current affairs (note that some exams, like IIFT, has a separate GK section)You get good reading practice. Whenever you read an article, try to summarize it on a piece of paper and see how much of it you retain. In Reading-Comprehension, a main question type in the Verbal section, retention skills are very valuableYou improve your vocabulary – whenever you come across words whose meanings you do not know, make a conscious effort to note those downYou get clarity of thought of the author (when you read editorials) – this helps in understanding the flow of the passageRead novels – this vastly helps you to improve your language skillsSubscribe to International dailies online (say, on Facebook), for example The Economist, BBC news, Wall Street Journal, etc. They present articles on a wide variety of topics. Remember that you can get Reading comprehension passages on politics, economics, philosophy, and even science. So it is best to read all sorts of topics.Solve Reading comprehension passages from past CAT papers, preferably from CAT 2010 onward.Get hold of the book – Dictionary of common errors – Longman publication, to get a very good grasp of common grammatical and word usage errors and how to rectify those.Logical ReasoningThis section deals with solving a variety of logic based questions – puzzles, seating arrangements, matrix arrangements, and so on. The best way to prepare for this is to practice questions on this topic. The best place to get questions on this topic is the book – The Great Book of Puzzles and Teasers by George J Summers.You would be surprised to know that a large number of logical reasoning questions asked in various exams are adapted from this particular book.At the same time, you should keep solving logical reasoning sets from past question papers. The questions asked in SNAP, IIFT and NMAT are usually on the easier side while those asked in XAT and CAT are usually the tougher ones. So initially you can start with the easier questions and gradually move on to the tougher ones. This practice would be definitely beneficial for you in your preparation for CAT 2019.Data InterpretationContrary to popular belief, this section in CAT does not necessarily have a lot of calculations. It is more on interpreting and analyzing data rather than performing calculations. The idea is to find patterns in data provided in forms of line graphs, bar graphs, pie charts and table formats. You first need to find which data areas required to answer a particular question. Accordingly, you have to focus on that part and solve the problem. Data interpretation questions for the past few years have been of a logical nature. Thus, it is expected that CAT 2019 would also be on similar lines.Similar to logical reasoning, skills required in this section are also developed by practice. The best source to practice would be past exam papers.Quantitative AbilityFocus on the basics. The syllabus consists of Arithmetic, Algebra, Geometry, Numbers, Sets, Permutation, Combination and Probability. Many questions in CAT are from the topics – Arithmetic and Geometry. In CAT 2018, almost 70% of the questions were from Arithmetic, Algebra and Geometry. The last few years also witnessed a similar trend. Thus, you should definitely focus on these areas for CAT 2019 as well.While preparing for the Quantitative Ability section, keep in mind the following:You should focus on the basic concepts and make sure that those are absolutely clear. Understand that the sections in Arithmetic – percentages, averages, ratios and rates (work and distance) are closely linked. Also, remember that concepts of percentages and ratios would also be required in data interpretation.Do not memorize unnecessary complicated formulae targeting specific question types. In the exams, barely you will get questions where you can use such formulae catering to specific types of questions. It is much better to apply basic concepts to solve the questions instead.You should practice a wide variety of questions. You can find a collection of basic level questions in the book by R S Agarwal. However, the questions in the exams would be of a tougher standard than those in the book. The best source for such questions is – as you might have guessed by now – past year question papers.So, essentiallyThis may seem a bit of a daunting task, especially when you have just started your preparations. Make sure that you give equal importance to each of the three sections in your preparation plan. If you are starting off now, ideally invest 2 to 3 hours daily to avoid a rushed up preparation later.Also you should remember to take a sufficient number of mock tests to check how your preparation is shaping up. We, at CUBIX make sure that the preparation for these exams is customized to the needs of each of our students. We follow an in-depth course curriculum.
