7Learn Data Science Specialist
The "7Learn Data Science" specialization is a comprehensive program that consists of 13 chapters that cover a wide range of topics in data science.
What I have Learned:
Throughout the program, I gained expertise in various statistical concepts, probability distributions, and functions, including normal, uniform, Bernoulli, binomial, polynomial, Poisson, and exponential. Additionally, the course covered important statistical analysis and comparison techniques such as the Kullback-Leibler test, Jensen Shannon criterion, and Kolmogorov-Smirnov criterion.
The course also delved into essential data processing techniques, such as ETL and ELT, Hadoop, and its ecosystem, as well as dimensionality reduction algorithms such as PCA, KernelPCA, ICA, ISOMAP, TSNE, and UMAP. The program provided me with familiarity in various algorithms used in data mining, such as SVM, Random Forest, Adaboost, XGBoost, and CatBoost, and the ability to find the best parameters for these algorithms.
Moreover, the course placed significant emphasis on natural language processing (NLP), text mining, and image processing. We covered image segmentation, classification, and deep learning using convolutional neural networks (CNN) and multichannel deep neural networks with multiple inputs. The course also covered techniques for handling imbalanced data, clustering, and outlier detection.
Throughout the course, I worked on several projects that involved solving real-world problems. One such project involved identifying cardiac patients using classification algorithms, while another focused on predicting cryptocurrency buy/sell behavior with recurrent neural networks. I also worked on a project that required recognizing diseases from chest x-ray images using CNN.
In conclusion, this course has provided me with comprehensive knowledge and practical experience in data science. It has empowered me to tackle complex problems and deliver data-driven solutions. I would like to extend my sincerest gratitude to Professor Masoud Kaviani, the esteemed instructor of the data science specialist course at 7Learn Academy. His profound knowledge, excellent teaching skills, and invaluable support have been instrumental in enriching my understanding of data science and expanding my skill set.
