In recent years, a deep learning model called convolutional neural network with an ability of extracting features high-level abstraction from minimum preprocessing data has been widely used. this research, we proposed new approach in classifying DNA sequences using the while considering these as text data. We used one-hot vectors to represent input model; therefore, it conserves essential position information each nucleotide sequences. Using 12 sequence datasets, evaluated our and achieved...
Protein function is regulated by an important mechanism known as post-translational modification (PTM). Covalent and enzymatic protein modifications are added during biosynthesis, such alterations significantly influence the regulation of gene activity functionality proteins. Glycosylation, one type PTM, involves adding sugar groups to a protein's structure. Numerous illnesses, diabetes, cancer, flu, have been linked glycosylation. Therefore, it critical predict presence glycosylation,...
Proteins play a vital role in life as essential macromolecules, consisting of linear heteromeric biopolymers formed by amino acids covalently bonded through peptide bonds. They contribute to cell development and bolster the body's defense mechanisms. Post-translational modification processes, such glycosylation, are necessary for proteins function optimally. Glycosylation involves adding sugar groups proteins, playing critical various protein folding processes. Dysregulation glycosylation...

In many animal-related studies, a high-performance animal behavior recognition system can help researchers reduce or get rid of the limitation human assessments and make experiments easier to reproduce. Recently, although deep learning models are holding state-of-the-art performances in action tasks, these not well-studied applying tasks. One reason is lack extensive datasets which required train for good performances. this research, we investigated two current I3D model R(2 + 1)D model,...
To classify DNA sequences, k-mer frequency is widely used since it can convert variable-length sequences into fixed-length and numerical feature vectors. However, in case of sequence classification, subsequences starting at a specific position the given also be as categorical features. Through performance evaluation on six datasets our algorithm based above idea achieved comparable or better than other state-of-the art algorithms.
Background Conventional in vivo methods for post-translational modification site prediction such as spectrophotometry, Western blotting, and chromatin immune precipitation can be very expensive time-consuming. Neural networks (NN) are one of the computational approaches that predict effectively site. We developed a neural network model, namely Sequential Spatial Methylation Fusion Network (SSMFN), to possible methylation sites on protein sequences. Method designed our model able extract...

We developed a ground observation system for solid precipitation using two-dimensional video disdrometer (2DVD). Among 16,010 particles observed by the system, around 10% of them were randomly sampled and manually classified into five classes which are snowflake, snowflake-like, intermediate, graupel-like, graupel. At first, each particle was represented as vector 72 features containing fractal dimension box-count to represent complexity shape. Feature analysis on dataset clarified...
