Cs260: Machine Learning Theory Lecture 13: Weak vs. Strong Learning and the Adaboost Algorithm
The big idea behind boosting is to construct an accurate hypothesis by combining the predictions of many individual hypotheses, each of which performs slightly better than random guessing on some particular distribution of data. This idea originally arose from attempts to prove robustness of the PAC model, in other words, attempts to prove that small changes to the model definitions don’t lead ...
متن کاملAnalyzing Intrusion Detection Using Machine Learning Adaboost Algorithm: An Observations Study
The current approaches for intrusion detection have some problems that adversely affect the effectiveness of the Intrusion Detection System. Current approaches often suffer from relatively high falsealarm rates. As most network behaviors are normal, resources are wasted on checking a large number of alarms that turn out to be false. Secondly their computational complexities are oppressively hig...
متن کاملA machine-learning algorithm for wind gust prediction
Physical damage to property and crops caused by unanticipated wind gusts is a well understood phenomenon. Predicting its occurrence continues to be a challenge for meteorologists and climatologists. Various approaches to gust occurrence model building have been proposed. The very nature of the event is problematic because of its brief duration following a rapid change of state in wind velocity ...
متن کاملConvolutional LSTM Network: A Machine Learning Approach for Precipitation Nowcasting
The goal of precipitation nowcasting is to predict the future rainfall intensity in a local region over a relatively short period of time. Very few previous studies have examined this crucial and challenging weather forecasting problem from the machine learning perspective. In this paper, we formulate precipitation nowcasting as a spatiotemporal sequence forecasting problem in which both the in...
متن کاملthe relationship between using language learning strategies, learners’ optimism, educational status, duration of learning and demotivation
with the growth of more humanistic approaches towards teaching foreign languages, more emphasis has been put on learners’ feelings, emotions and individual differences. one of the issues in teaching and learning english as a foreign language is demotivation. the purpose of this study was to investigate the relationship between the components of language learning strategies, optimism, duration o...
