ensemble-learning-with-credit-card-application

In this study, the credit card operation dataset was used where the original dataset in the UCI Machine Learning Repository is available. The aim of the analyze is predict whether or not a given customer should be approved for their credit application. I am dealing with six different ensemble learning techniques such as Averaging, Weighted Averaging, Max Voting, Bagging, Boosting, Stacking. Explanations of the applied techniques have been made. While using these methods, Packt course was used for the necessary definitions.

sentiment-analysis-on-stocks-data-using-natural-language-processing

This study is about creating a sensitivity classifier model using messages from customers. We have a binary classification problem that categorizes stock sensitivity data as positive or negative. 1 indicates positive sentiment and 0 indicates negative sentiment. The main resource I used in the study is the Python & Machine Learning for Financial Analysis course on Udemy. The main steps are as follows: Importing required libraries(pandas,numpy,seaborn,matplotlib,nltk,gensim,tensorflow) Explanatory Data Analysis Data cleaning (removing punctuations and stopwords from text) Visualization of cleaned dataset and plotting wordcloud Prepare the data by tokenizing and padding Building a custom-based deep neural network for sentiment analysis (embedding layer, LSTM network) Making prediction and assessing the model performance (confusion matrix)
