As a Spanish speaker, do you find English vowel sounds difficult? In this course, you will learn the pronunciation of all the English vowel sounds, especially the difference between short and long vowel sounds. Why? Because Spanish vowels are not as long as English ones, Spanish speakers find it difficult to know when vowels are short or long!We will explore how to say the vowel sounds in isolation, the typical spelling and exception of these sounds in words and phrases, compare and contrast them with other sounds and learn about word stress. If you are consistent and practise what you learn, you will improve and your confidence in speaking English will increase!You will be able to see my face and mouth clearly in each video lesson and I will use a background to show the vowel sounds and example words.This course includes audio files, worksheets and quizzes, to help you practise your pronunciation which can only be improved through listening and repetition. As a language learner myself, it’s not enough just to listen to the teacher say the sound a few times, the learner needs the opportunity to listen and repeat as many times as possible. I also recommend recording yourself because what you think you are saying is often different to what you’re actually saying!This approach will help you to make the vowel sounds correctly and help to build your confidence when communicating in English.Go at your own pace and take your time. Some of the vowel sounds, especially those that do not exist in Spanish, may take you longer to say naturally. Be patient! Listen to the video and the audio files many times, if necessary.If you’re ready to speak English more naturally and confidently, there’s only one thing left to do: Sign up now!

Data cleaning or Data cleansing is very important from the perspective of building intelligent automated systems. Data cleansing is a preprocessing step that improves the data validity, accuracy, completeness, consistency and uniformity. It is essential for building reliable machine learning models that can produce good results. Otherwise, no matter how good the model is, its results cannot be trusted. Beginners with machine learning starts working with the publicly available datasets that are thoroughly analyzed with such issues and are therefore, ready to be used for training models and getting good results. But it is far from how the data is, in real world. Common problems with the data may include missing values, noise values or univariate outliers, multivariate outliers, data duplication, improving the quality of data through standardizing and normalizing it, dealing with categorical features. The datasets that are in raw form and have all such issues cannot be benefited from, without knowing the data cleaning and preprocessing steps. The data directly acquired from multiple online sources, for building useful application, are even more exposed to such problems. Therefore, learning the data cleansing skills help users make useful analysis with their business data. Otherwise, the term 'garbage in garbage out' refers to the fact that without sorting out the issues in the data, no matter how efficient the model is, the results would be unreliable. In this course, we discuss the common problems with data, coming from different sources. We also discuss and implement how to resolve these issues handsomely. Each concept has three components that are theoretical explanation, mathematical evaluation and code. The lectures *.1.* refers to the theory and mathematical evaluation of a concept while the lectures *.2.* refe
