kandi X-RAY | Bender Summary

Bender is a Swift library typically used in Artificial Intelligence, Machine Learning, Deep Learning, Tensorflow applications. Bender has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Bender is an abstraction layer over MetalPerformanceShaders which is used to work with neural networks. It is of growing interest in the AI environment to execute neural networks on mobile devices even if the training process has been done previously. We want to make it easier for everyone to execute pretrained networks on iOS. Bender allows you to easily define and run neural networks using the most common layers like Convolution, Pooling, FullyConnected and some normalizations among others. It is also flexible in the way it receives the parameters for these layers. We also want to support loading models trained on other frameworks such as TensorFlow or Caffe2. Currently Bender includes an adapter for TensorFlow that loads a graph with variables and "translates" it to Bender layers. This feature supports a subset of TensorFlow's operations but we plan to enhance it to cover more cases.

            How to force Gurobi to use presolve phase?
            Asked 2021-Jan-12 at 13:40

            I am using the Benders decomposition and solve a linear subproblem at each iteration. To save time, I generate the subproblem out of the benders while loop. At each iteration, I solve the master problem and update one of the subproblem constraints and then optimize the subproblem. Since my subproblem is a large problem, presolve during the model. optimize() may help the algorithm. In this respect, I set model.setParam("presolve",value) with value=-1,1,2 (currently none of these options help me with my problem). In the first iteration, in the presolve phase, rows and columns are removed and the model is solved in a reasonable time. However, in the second iteration, the log does not show any presolve phase and due to the problem structure, it can not solve the lp problem. My question is this: How can I force Gurobi to run the presolve phase while optimizing the problem during each iteration? I do not want to use  p.model.presolve()  and p.optimize() because with this, solver miss the dual information of the removed constraints in problem p and I cannot map the solution of p to the solution of the original problem. In the following, you can find the log of the small instance (I have the same problem in the large instances). As you can see in the second iteration, I don't have the presolve phase. I'm using Gurobi 9.0.1 with python 3.7.

            Most likely, the solver is warm-starting from the previous optimization. This will happen if you just change a few parts of the model and don't construct a new model from scratch. Maybe, you can try to call Model.reset() to start a new optimization from scratch with full presolving.

            It's hard to tell what you're doing without seeing the source code, though.

            Is there a way to assign a value to a thing based on where it appears in a list?
            Asked 2020-Nov-17 at 13:13

            I have six letters [a,b,c,d,e,f] and two users [bob,bender]. They both have a different arrangement of the letters that represents them, think personality score-ish. Bob is [e,f,c,b,a,d] and Bender is [b,a,d,f,e,c].

            I also have a chart to put these on. Each letter, in order, has it's own bar on the chart and the ticks go up to 6.

            Depending on where in the list the letter appears it has a number value assigned. The first letter gets a value of 6, the second a value of 5, and so on.

            The final array needs to be in abc order, but with the correct value for each letter. Example: Bob would end up with [2,3,4,1,6,5].

            How would you do this?

            The only way I can figure is a ton of if statements and I'm trying to see if there's a better way.

            The array subexpression operator @() returns its results as [object[]] - a type which satisfies the argument type [IEnumerable[object]] - which is why it always works when you use [object] as the type parameter for the receiving collection type.

            So, what to do about that?

            If the array consists only of [Thing]'s, you can explicitly cast to a more specific collection type that implements [IEnumerable[Thing]]:

            First, some background on what I'm trying to do. I am writing a PowerShell script module that needs to set some variables and run some code when the module is imported. What ultimately needs to happen is dependent on the version of PowerShell the module is being imported into. For example, this needs to support 5.1 and later, but Invoke-RestMethod does not support the

            I am working on MILP model (In DoCplex) and solver reaches the solution faster with Benders Method sometime and sometimes using Branch & Bound. Is there an easy way to run both solve methods parallel without changing variable names (cloning the model) on same model. And use output from one of the solve.

            Answered 2020-Aug-25 at 04:30

            You cannot solve the same model with two algorithms simultaneously. However, it should be easy to create the same model twice and then solve it concurrently in two different threads or processes. You will have to use the threading or multiprocessing Python modules for this.

            One very simple and convenient way on a Unix-like operation system (like Linux or MacOS) would be to use os.fork() to create a new process for each solve and then control them from the initial process. fork() implicitly clones the model, so it can save you some lines of programming.

            Purpose of typealias
            Asked 2020-Aug-19 at 08:51

            I thought that today I finally understood what is typealias for.

            I didn't.

            1. typealias is literally for creating an "alias" (i.e. another name) for a type. You are not creating a new type, just another name for an existing type. From the Language Reference:

              Type aliases do not create new types; they simply allow a name to refer to an existing type.

              Therefore, once you declared the typealias, Graph and [String: [String]] now refers to the same type. An extension on Graph is equivalent to an extension on [String: [String]].

            2. For your desired behaviour, you need to create a new type. For a Graph, I think a struct would be appropriate:

            ANSWER

            Answered 2020-Aug-18 at 13:45

            There are different formulas to calculate the relative optimality gap. It depends on the solver you use, which one is applied. Some info about this can be found in the description of the GAMS option optCR . The solver manual of the solver you use could have more details about the formula actually applied.

            EDIT after question was updated:

            As you wrote mymodel.objval returns the Final Solve value. If you want to see the MIP Solution value instead (as the Cplex link does it internally), you could deactivate the final solve. However, if Final Solve and MIP Solution are so much different as in your example this is often an indication for some problem (usually, they are (nearly) identical). Often, this indicates a poorly scaled model. Maybe you could improve the situation by tightening the Cplex tolerances (see Cplex options epopt, eprhs, epint) and activating aggressive scaling (Cplex option scaind 2). Activating mipkappastats (https://www.gams.com/latest/docs/S_CPLEX.html#CPLEXmipkappastats) and quality (https://www.gams.com/latest/docs/S_CPLEX.html#CPLEXquality) could give you more information. DataCheck=2 (https://www.gams.com/latest/docs/S_CPLEX.html#CPLEXdatacheck) might show some problems.

            Answered 2020-Aug-04 at 04:31

            In your code you solve multiple optimization problems in parallel. This is fine but there is a catch: By default a single CPLEX instance will use as many threads as your machine has cores and will try to keep them busy. So if you solve N models in parallel, then on each core N instances of CPLEX will compete for computing resources. This is usually not a good idea since CPLEX processes are more or less completely CPU bound.

            One option to speed up your code would be to avoid that multiple CPLEX threads run on the same core. For example, if you have 12 cores and run 3 solves in parallel, then make sure that each of these solves uses only 4 threads.

            In order to limit the number of threads for a single solve use parameter IloCplex::Param::Threads.
