Image‐Guided Radiation Therapy (IGRT) is a cancer treatment method. IGRT usually follows a fragmented treatment track. The weight loss of a patient causes the first treatment plan to be flawed. Medical experts can avert retaking Fan Beam Computed Tomography (FBCT) images before each session of the therapy if the Cone Beam Computed Tomography (CBCT), which is mounted on a Medical Linear Accelerator (LINAC), gives high‐quality images. Rather than improvising the CBCT machine, deep‐learning techniques can be used to enhance the CBCT images. This paper proposes a Feature‐Embedded Variational AutoEncoder (FE‐VAE) for CBCT image enhancement. A feature embedding is incorporated using a MultiResUNet‐based feature extractor to preserve structural information in the input image. A perceptual loss function, which is the product of Mean Absolute Error (MAE) and inverse Structural Similarity Index Measure (SSIM), is proposed in this work. The model is trained using Head‐and‐Neck (H&N) CBCT‐FBCT ...

Natural language processing (NLP) is a field of computational linguistics. NLP deals with analyzing, and understanding the human languages that are used to interface with computers via natural languages instead of using computer languages. In this era databases are used in many fields like banking, human resources, universities etc. That is people around the world need to deal with databases for the extraction of required data. But it is very difficult for a common user to retrieve information from the database using database query languages. Access any kind of data from database using natural language like English is a convenient and easy method instead of using formal query languages such as XQuery, SQL etc. The system which provides such a facility is known as Natural Language Interface to Databases. Some of the works in this area are discussed here.
