Good morning everyone. I really want to appreciate everyone in this page. Came across it last month and I've never been so motivated. I've been able to get a PC, some of the materials recommended here. Right now, I'm learning excel. Still trying to balance it out with work. Hearing that others like me are putting in the effort to be better, is enough motivation for me. So, I just want to say thank you to all of you. PS. If you're new to the thread, try to start from the beginning. Take note of the recommended courses. Source for them online. 5 Likes |

Teophilus96: For data science questions: 1st thing 1st, make sure you have a project you can walk them through on how you build your model. read on implementation of end to end machine learning model from data collection, EDA, feature selection, feature engineering, model selection, training of the model, hyper parameter tuning and model deployment. Read on performance metrics like confusion, matrix, f1_score, accuracy and precision for classification model and mea squared error and root mean squared error for regression. Clearly state the difference between regression and classification problem. Also read on Unsupervised learning and use case. For instance Kmean algorithm for Segmentation. Read on Dimensional curse in ML and how to correct them with PCA How to remove outliers How to treat imbalance datasets. Then some Python basics syntax with focus on numpy, pandas and visualization tools like seaborn and matplotlib. I wish you the best of luck 8 Likes 3 Shares |

Teophilus96: Hi for the update, I got the job offer. During the interview I felt quite uneasy and nervous at the start. I was given the company data to work on and provide certain insights. I tried using MySQL to query the data and obtain certain pattern since the data was not clean at all. MYSQL failed me lols, so I ended up using POWERBI to do whole stuff. I have been waiting to share this news untill they get back to me. Thanks you all, I wish us all the very best! 18 Likes 1 Share |

Through this thread, I was motivated to start learning excel and Sql (through youtube and web materials), I can say I can comfortable use both to some extent. Hoping to be good in those before moving to Tableau and then Python. However, I am having issue on how I can start to put what I've learnt into use. For Instance, I've got Data files on Airline performance from 1987 to 2008, I am to analyze and treat this data, they are about for 22 files with each having over 1 million rows of record. I'm not sure if I should import these files through Excel -Data- Query, merge them(this may be too large for excel) and try to make sense out of it, or I need to find a way to get the files into PostgreSQL. I will appreciate comments on the process to treat a data like this or how to start with it. Lastly, I am looking for a mentor or coach, someone who is already in the field, I don't mind discussing terms. Things are easier for me when I have access to someone I can ask this questions whenever I'm stuck. Thanks 1 Like |

Re: Chronicle Of A Data Scientist/analyst by Felixitie(m): 11:41am On Apr 01, 2022 |
Omotaday: Excel Power pivot should handle that or powerbi. If the files are in csv you could import them into sql server or mysql. 2 Likes |
