    A probabilistic approach for obtaining an optimized number of services using weighted matrix and multidimensional scaling Md. Shamim Towhid

    While migrating from Monolith to Microservices architectural style, it is often confusing to define service boundaries. This paper describes a probabilistic technique to define the services on a Monolithic system considering three major aspects - update rate, scaling rate, and technology diversity necessary to realize each service properly. To do so, we have used the weighted matrix and Multidimensional Scaling (MDS). This technique helps to define an optimal number of services for implementing the system in the Microservices Architecture. This paper will be useful for organizations trying to migrate from Monolithic System to Microservices.

    Spectrogram segmentation for bird species classification based on temporal continuity
    (Institute of Electrical and Electronics Engineers Inc., 2017) Towhid, M.S.,; Rahman, M.M.
    This article presents an enhanced approach for bird species classification from their recorded audio signals. Observing that textures of syllables in audio spectrograms have noticeable discerning capabilities among different bird species, we adopt these texture features for bird species classification. First, we compute spectrogram from recoded audio. We propose an enhanced syllable extraction technique to identify the syllables in the spectrogram. Texture features, based on gray level cooccurrence matrix (GLCM), are computed and used for classification using an ensemble learning method. We obtain satisfactory accuracy when the approach is tested on real audio recordings of 11 different bird species.
