INTRODUCTION to DEEP LEARNING kgDeep inspired learning is a AI subset of machine learning by the neural networks in the human brain mania Learning 2How the GPUs work why do they chosenfor these type of Deep Learning application has already been used in scientific field such as by It computer vision Natural Language Processing speech Recognition and many others proved suitable to solve well defined logical problems such as playing by AI cheese LEARNING MACHINE G The to make by A objective of machine learning is to capture regularity in data general predictions machine learning Rules system is trained rather classicalprogramming Data byTypes of Supervised seni machine learning Answer Data Answers than explicitly Machinelearning programmed rules algorithms Learning supervised learning Unsupervised Learning Reinforcement learning Supervised ByThe Learning machine is thought by example as The operator provides the ML algorithm with a known dataset that includes desired inputs and outputs and the algorithm must find a method to determin how to arrive at those inputs and outputs bg The algorithm identifies patterns indata learns from observations andmakes predictions kg The algorithm this process performance makes predictions and is corrected by the operator and continues until the algorithm achieves a high level of accuracy Unsupervised Kg The learning ML algorithm studies data to identify ay There is answer key or human operator to provide instruction no be Instead the machine determines available data by In an unsupervised kgThe algorithm tries to learning process the the and address that data accordingly structure byThis might patterns mÂĞĞʰĞ 7Ü organise that data in some interpret by analysing large data sets way to describe its grouping the data into clusters or arranging it in mean that looks more correlations and relationships organised a way Semi supervised Learning kg Semi supervised learning labelled and unlabeled bg Labelled algorithm Ey By data is supervised learning data but instead uses both that has meaningful tags so that the the data whilst unlabeled data lacks that information essentially information can understand using this is similar to combination MLA can learn to label unlabeled data Reinforcement Learning by RL focuses with a on set of regimented learning process where actions parameters and end values a MLA is provided Bs By defining the rules the MLA then tries to explore different options and possibilities monitoring and evaluating each result to determine which one is optimal as Reinforcement learning teaches the machine trial and error learns from post experiences and begins to adopt its approach in response to the situation to achieve the best possible result Sylt Fromdata is an
