• Relational databases: store data in tables with rows and columns (e.g. MySQL, PostgreSQL)

• NoSQL databases: flexible, schema-less databases (e.g. MongoDB, Cassandra)

• Graph databases: store data in nodes and edges to represent relationships (e.g. Neo4j)

• Time-series databases: optimized for storing and querying time-stamped data (e.g. InfluxDB)

Ridge and Lasso are regularization techniques in regression to prevent overfitting by adding penalty terms to the cost function.

• Ridge regression adds a penalty term equivalent to the square of the magnitude of coefficients (L2 regularization).

• Lasso regression adds a penalty term equivalent to the absolute value of the magnitude of coefficients (L1 regularization).

• Ridge regression tends to shrink the coefficients towards zero but does not set them exactly to zero.

• Lasso regress...read more

Reflections in C# allow for runtime inspection and modification of types, objects, and assemblies.

• Reflections can be used to dynamically load assemblies and types at runtime.

• Reflections can be used to inspect and modify properties, fields, and methods of objects.

• Reflections can be used to create new instances of types and invoke their methods.

• Reflections can be used to generate code dynamically using System.Reflection.Emit namespace.

• Reflections can be slow and should be used ...read more

• Agile involves continuous feedback and adaptation, while waterfall follows a linear approach.

• Agile allows for changes throughout the project, while waterfall requires detailed planning upfront.

• Agile promotes collaboration and communication among team members, while waterfall has distinct phases with limited interaction.
