(De Gruyter, 4/9/2021) Das, Amit Kumar; Al Asif, Abdullah; Paul, Anik; Hossain, Md. Nur
Hate speech has spread more rapidly through the daily use of technology and, most notably, by sharing your opinions or feelings on social media in a negative aspect. Although numerous works have been carried out in detecting hate speeches in English, German, and other languages, very few works have been carried out in the context of the Bengali language. In contrast, millions of people communicate on social media in Bengali. The few existing works that have been carried out need improvements in both accuracy and interpretability. This article proposed encoder–decoder-based machine learning model, a popular tool in NLP, to classify user’s Bengali comments from Facebook pages. A dataset of 7,425 Bengali comments, consisting of seven distinct categories of hate speeches, was used to train and evaluate our model. For extracting and encoding local features from the comments, 1D convolutional layers were used. Finally, the attention mechanism, LSTM, and GRU-based decoders have been used for predicting hate speech categories. Among the three encoder–decoder algorithms, attention-based decoder obtained the best accuracy (77%).
Mortgage securitization project of Standard Chartered Bank
(BRAC University, 9/20/2012) Das, Amit Kumar; Haque, Samina
In Bangladesh there are numbers of bank stands among them some bank are known as government bank, some are known as private & some other are known as foreign bank or multinational bank. The subtotal of all banks in Bangladesh stands at 52, among them Standard Chartered Bank (SCB) is the leading multinational bank which successfully operate their business in Bangladesh. Standard Chartered Bank opened its first branch in Chittagong in 1947 which, at that time was the eastern region of the newly created Pakistan. The bank opened its first branch in Dhaka in 1966 and shifted it’s headquarter from Chittagong to Dhaka after the birth of the Republic of Bangladesh in 1971. The bank has a great history and it create a huge impact on bank business. Standard Chartered Bank is the market leader in all aspects of the banking industry, with the exception of their competitive position in Lending due to its conservative stance on taking too large an exposure on the comparatively volatile Bangladeshi market. As a result, the bank has shifted its portfolio from lower to higher quality lending compared to other banks operating in Bangladesh. It is inevitable that better approaches and frameworks will come up in the future because of Standard Chartered Banks relentless determination to lead the way in the banking sector in Asia, Africa and the Middle East. Standard Chartered started the mortgage business in Bangladesh in 2007. After starting this business Standard Chartered Bank became the market leader in mortgage loan within 2 years. Standard Chartered Bank always insured the security of their assets. In this report I focused on how the Standard Chartered Bank secured their mortgage loan.
