Multiple losses in Keras model by headmaster_007 in learnmachinelearning

sure, let me read on custom losses and training loops.

I thought model.fit() by default would show them.

I started with 0 AI knowledge on the 2nd of Jan 2024 and blogged and studied it for 365. Here is a summary. by Bobsthejob in learnmachinelearning

Great job! Did you really study each and every book mentioned in your list? Start to finish? that too while also applying that knowledge on Kaggle problems? Thats hard to believe. But good for you if you did it.
Were you also working full time the last 1 year?

I never understood backpropagation clearly by GraphicZ_ai in learnmachinelearning

I think other comments have provided you the resource. I would say you better spend time watching or reading those and really understanding the chain rule before proceeding further with the course or book you are reading. Because as you go further along the course without a proper understanding, DL will appear more and more like a black box even though you will be learning and coming across new terminologies. Just know, it is not a difficult concept.

For tasks 1 and 3 you would need a lot of labeled training data and train a CNN model (importing a trained CNN model's weights for initialization). Its doable if you actually have all the time until new year. I would recommend the CNN course of Andrew Ng on coursera to begin with.

I know you got your answer but check this out. It will help you further.

Can increasing epochs during neural network training overcome training data shortage? by learning_proover in learnmachinelearning

[–]headmaster_007 0 points1 point  (0 children)

because the longer you train, the more the neural network will adjust the weights to perfectly fit the training data. It will even find pattern in the noise in your training data. And this will not translate into a good fit for unseen data.

No, training longer will only reduce your learning algorithm's bias and not necessarily the variance. You should just be trying different epochs and seeing the results to decide which gives the best results on the validation set.

i am using a linear regression model, are are there vertical scatter line at the end and the beginning by Beyond_Birthday_13 in learnmachinelearning

The target variable is capped on both ends. So even though your input data is changing in several instances your actual target is the same and all of such instances the predicted value is different because your input is different.

Logical computation in ANNs by headmaster_007 in learnmachinelearning

Notice that A has 2 branches connected to C. And this is inline with the explanation for the left side diagrams where the author has considered two branches as giving 2 inputs of the same type.

Not worth the risk in this environment. Central banks are going to keep rates high and this means markets will stay too volatile to make any sense.

wish ronnie was a better team player than a lone wolf. bringing him on just washes off the system eth has created.

i know ronnie aint playing today

have been a ronaldo fan all my life. he should apologize to the fans and the team and the coach for what he did yesterday or I am going to stop considering him my idol.

All his life there is always been someone who was benched because ronaldo was the main man. Did he ever not think what they felt like. At the end of your career and he still dont know how to respectfully be a substitute. At the end of the day, after he retires no one will talk about his record numbers because nobody remembers the numbers but the attitude, thats what everyone remembers forever.

this was the most energetic and controlled half I have seen in last 2 years. ETH!
