Data Science, Machine Learning and Artificial Intelligence Tutorial
Boosting helps to improve the accuracy of any given machine learning algorithm. It is algorithm independent so we can apply it with any learning algorithms. It is not used to reduce the model variance.
Boosting involves many sequential
iterations to strengthen the model accuracy, hence it becomes computationally costly.
Ensemble Learning says, if we can build multiple models then why to select the best one why not top 2, again why not top 3 and why not top 10. Then if you find top 10 deploy all 10 models. And when new data comes, make a prediction from all 10 models and combine the predictions and finally make a joint prediction. This is the key idea of ensemble learning.
It does not matter how much subject knowledge you have, until you do not get a chance to show case it. It will be hidden somewhere within you. If you cannot market yourself well then you will always be lost in the crowd. So why am I talking about all these things. Imagine you are searching for a job and you have all the credentials required, however you are not getting shortlisted even. So what to do? Where is the problem? Are you marketing yourself well? Let’s discuss all these points in details.
It does not matter how much experience you have, actually anybody can start or switch to data science and machine learning. The only important this is, how much eager you are for it. What it means to you. If you are very much keen to work in this field then nobody can stop you. There might be some short term hurdles however if you are focused enough and know your goals regarding where you want to see yourself after certain years, then you will definitely be successful in overcoming those hurdles.
Lot of research is being done in medical field, where researchers are working to develop AI models which can even develop the “Sense of smell”.It will help medical field to detect illness by smelling the human’s breath.They have achieved great success in detecting chemicals called aldehydes. Aldehydes are associated with human illnesses and stress.
Bayes Theorem is the extension of Conditional probability. Conditional probability helps us to determine the probability of A given B, denoted by P(A|B). So Bayes’ theorem says if we know P(A|B) then we can determine P(B|A), given that P(A) and P(B) are known to us.
