Motivation | Mac screen saver that terrifyingly shows your age

I was reading a decent paper S-DCNet and I fell upon a section (page3,table1,classifier) where a convolution layer has been used on the feature map in order to produce a binary classification output as part of an internal process. Since I am a noob and when someone talks to me about classification I automatically make a synapse relating to FCs combined with softmax, I started wondering ... Is this a possible thing to do? Can indeed a convolutional layer be used to classify a binary outcome? The whole concept triggered my imagination so much that I insist on getting answers...

Honestly, how does this actually work? What is the difference between using a convolution filter instead of a fully connected layer for classification purposes?

Edit (Uncertain answer on how does it work): I asked a colleague and he told me that using a filter of the same shape as the length-width shape of the feature map at the current stage, may lead to a learnable binary output (considering that you also reduce the #channels of the feature map to a single channel). But I still don't understand the motivations behind such a technique ..

Is there a way to combine two structs struct A and struct B into a third struct C in a way that changes to either struct A or struct B, like adding a new field, are automagically reflected in struct C?

The motivation is that e.g. struct A comes from some library and struct B and is under my control and contains additional data not found in struct A; the purpose of struct C is to access the members of struct A and struct B via a uniform interface represented by struct C.

pseudocode:

Here's an elementary loop, which compiles fine when outside of an assignment block:

Why introduction text was overlaid by the profile image when the browser was scaled down to 650px? They suppose to show in 100% width at 650px screen. I did adjust the position of .speakers-info from absolute to relative, it seems solved the overlay problem but then all position setting got messed. Please see the code as below and advise how to solve it, thank you!

I've got this JSON:

I have already installed an OSRM server - just the backend. And I have used it with Leaflet to calculate routes. I want to test other services so I came across Graphhoper.

Contrary to OSRM I can't find a manual on how to set up a local server. I want to have just the backend of Graphhoper that would do the calculations and pass them to Leaflet. My motivation for the local server is also the fact that in that case no API Key would be needed.

Is it even possible to install only the backend of Graphhoper? Or am I understanding something wrong?

Thank you in advance

Note: understanding IEEE 754. Please be patient.

IEEE 754-2008 (emphasis added):

In addition, under default exception handling for underflow, if the rounded result is inexact — that is, it differs from what would have been computed were both exponent range and precision unbounded — the underflow flag shall be raised and the inexact (see 7.6) exception shall be signaled. If the rounded result is exact, no flag is raised and no inexact exception is signaled. This is the only case in this standard of an exception signal receiving default handling that does not raise the corresponding flag. Such an underflow signal has no observable effect under default handling.

As I understanding it: underflow == inexact && tiny.

Simple question: why Underflow depends on Inexact?

I.e. why if exact subnormal is produced, then no Underflow exception is raised? What is the motivation / rationale of such behavior?

I've come across a piece of code where the same const variable is redeclared several times in a for-loop, like so:

Let me write the relation that A is a sub-class of B by A < B. Suppose there is a relation A < B < C between three classes.

Now, what I want to do is to define a function/class-method that can take argument of all A, B and C (all the sub-class of A). Is it possible? and if so, how can I do this?

EDIT: MOTIVATION The motivation of this is as follows: Let say I want to solve a maze. The solver function solve_maze takes a Maze and solve the maze. By default, is_obstacle_free is set to return true always. This means that default maze is the empty space.

What I want to do is, enabling the user to define their custom CustomMaze by inheriting the Maze class if they want. User can change the shape of the maze by tweaking the is_obstacle_free function. Maybe, another user want to define class CustomMaze2 inheriting from CustomMaze.

If I can define solve_maze function that accept any sub-type of Maze, we can avoid defining solve_maze anytime users added a new maze type.
