The java.lang.NoClassDefFoundError is a distinct runtime exception in Java that indicates the JVM could not find a class it needed to load during execution, even though the class was present and compilable when the code was initially built. It’s crucial to differentiate this from a ClassNotFoundException, which typically occurs when the class loader cannot find a class at all, whereas NoClassDefFoundError suggests the class was visible at compile-time but somehow became unavailable at runtime. When you encounter java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException, the error message can […]
When you’re deep into the world of deep learning and tackling classification tasks, especially with powerful frameworks like TensorFlow and Keras, selecting the perfect loss function isn’t just a minor detail, it’s a pivotal decision. You’ll frequently encounter two prominent options: binary crossentropy (often used for binary and multi-label classification) and categorical crossentropy (the standard for multi-class classification). What’s fascinating, and sometimes perplexing, is that even when you apply both to what seems like the identical dataset, they can produce remarkably different performance […]
