This module outlines the conclusions we made about CNNs and the future steps we could take with our project.
Conclusion and future steps
Given our results, we conducted some additional exploration into manipulations of the kernels produced by the convolutional layers. One such manipulation was the production of a library of useful looking filters generated by multiple separately trained networks, and the injection of these filters into the first convolutional layer of an untrained network, then training the network. We experimented by freezing the initial layer so the weights and biases associated with the kernels in the first layer would remain as the ones that were injected, and proceed to train the network. The result was a substantial speedup in learning, reaching an accuracy of 95.43% after a single epoch, compared to the 80.21% and 60.32% obtained by the networks that generated the kernels that were injected into the test network. Unfreezing the layer and continuing training did not yield any useful results. The accuracy of the network did not increase substantially more after additional training. The primary conclusion is that initializing weights and biases in the convolutional layers to ones previously learned in a separate network can substantially decrease the time it takes for a network to learn. A future elaboration would be to not even generate kernels using previously trained networks, but to initialize weights using prototypical image processing filters. If convolutional nets are able to be initialized with useful filters initially, they may be able to substantially reduce the amount of time required for a network to learn, or perhaps increase accuracy.

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

What is the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

A boat travels due east at a speed of 40meter per seconds across a river flowing due south at 30meter per seconds. what is the resultant speed of the boat
which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
pratica A on solution of hydro chloric acid,B is a solution containing 0.5000 mole ofsodium chlorid per dm³,put A in the burret and titrate 20.00 or 25.00cm³ portion of B using melting orange as the indicator. record the deside of your burret tabulate the burret reading and calculate the average volume of acid used?
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you.
Attracting depends on the mass och each body and distance between them.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?
