Train a ML.NET algorithm is the activity that we need to do when we want to prepare and algorithm to predict some values. As we'll see we have to prepare the pipeline with some operations that will be propedeutic to the training, like load the dataset, convert alphanumeric colums and so on. Now that we … Continue reading Training, prediction and evaluation with ML.NET

Choosing an ML.NET algorithm
A tipical question when we approach a machine learning problem is: what is the algorithm that fits better in my dataset? In the previous post we have seen the possible classifications for the ML.NET algorithms and this is the first step to restrict the possible choices. Now we can make considerations about what are our … Continue reading Choosing an ML.NET algorithm
Machine Learning algorithms tipologies in ML.NET
ML.NET is a new open source project released by Microsoft few months ago implemented for .NET applications and available as a NuGet package. Now in version 0.4 is growing rapidly but it already has a significative number of algorithms that show the power of the framework. It's a group of libraries used internally by microsoft … Continue reading Machine Learning algorithms tipologies in ML.NET
Resetting Entity Framework migrations
It's very often that when working on projects that has years of life and we are using Entity Framework, the migrations growth a lot over time and suddenly we encounter problems when we try to add new ones. Furthermore, opening the migrations folder and see tons of migration files is not very nice, so we … Continue reading Resetting Entity Framework migrations
Deferred execution with LINQ
The execution of queries on collection of objects in C# is an operation that we can do of course using LINQ, the popular component introduced 10 year ago in the .NET framework. With LINQ we can write queries on objects with a SQL-like sintax, it give us a lot of flexibility but, as all the … Continue reading Deferred execution with LINQ
Reliable RabbitMQ consumer with C#
Message Brokers like RabbitMQ are the most common solution for decouple the communication between two different application and add an intermediary between them. With this solution there are many benefits, like asynchronous communication, indipendent protocols between the applications, definition of rules for routing messages and in case of RabbitMQ an efficient protocol like AMQP to … Continue reading Reliable RabbitMQ consumer with C#
RabbitMQ consumer with C#
In the previous post I talked about a RabbitMQ publisher and how we can implement it with C#. The next step is implement a consumer and we'll see how we can do that efficiently; unlike the publisher, the consumer has more implication and as we'll see, we can consume messages from RabbitMQ in different ways. The … Continue reading RabbitMQ consumer with C#
RabbitMQ publisher with C#
RabbitMQ is one of the most popular message broker used to decouple the communication between different application and components. It has a nice and clear documentation with simply tutorials to understand the capabilities of the middleware; it implements the AMQP protocol and it offer a client for different enviroments and languages, like C#, Java, Python, … Continue reading RabbitMQ publisher with C#
Deleting related entities with entity framework
Entity framework has some features and peculiarities that are useful in a lot of situations and with they can help us to do some operations in very smart and efficient mode. Anyway in some circumstances it could surprise us with some very strange side effects or behaviors that may we don't know; we can meet … Continue reading Deleting related entities with entity framework
Managing SSH connections with C# Part 2
As discussed in the previous post, disposing an SSH connection is very important to free the port and leave it usable to the next connection. Unfortunately, implementing the connector as disposable is not enought, because if the application crash or stop unexpectedly, the dispose method will no be called and the port will remain busy … Continue reading Managing SSH connections with C# Part 2
