딥러닝 CNN 완벽 가이드 - TFKeras 버전
Y = W1*X1 + W0를 2차원 좌표상에서 나타냈을때, 예측함수에 실제값을 더하면 실제함수가 나온다고 하셨는데 혹시 왜그런지 알수있을까요? 만약 2개의 ERROR값이 Y = W1*X + W0를 중심으로 대칭이동을 하게되면 ERROR값은 0이 나온다고 생각합니다. 답변 부탁드립니다 !

딥러닝 CNN 완벽 가이드 - TFKeras 버전
plt.plot(history.history['accuracy'], label='train') plt.plot(history.history['val_accuracy'], label='valid') plt.legend() 부분에서 x축은 epochs의 수이고 y축이 정확도인거죠?? plt.plot에서 파라미터가 history.history['accuracy']만 있어서 헷갈리네요 ㅠㅠ plt.plot()메소드에 파라미터로 x축과 y축 둘 다 넣어줘야 되는거 아닌가요???

딥러닝 CNN 완벽 가이드 - TFKeras 버전
안녕하세요 이전에 질문드렸던 내용과 중복 되지만 문의드립니다. 첨부된 사진과 같이 버전이 이전으로 downgrade하였지만 kaggle 에서 restart를 하여도 여전히 막혀있습니다. 해당 내용 확인 가능하실까요?

실전! Querydsl
안녕하세요 oracle db에서 서브쿼리 안에서 groupby를 했을떄 ORA-02287 sequence number not allowed here 오류가 나옵니다. 검색해보니 SEQUENCE를 사용할 수 없는 경우는 다음과 같다. SELECT 문장의 경우에서 1. WHERE 절 안에서 2. GROUP BY나 ORDER BY 절에서 3. DISTINCT 절에서 4. UNION 이나 INTERSECT 나 MINUS 와 함께 사용 할때 5. 서브 쿼리 안에서 라고 하는데 제 경우에는 이 group by를 하고싶으면 어떻게 할수있나요? 감사합니다. Integer sucessCount =0, JPQLQuery<Tuple> subQuery = JPAExpressions.select( log.name, log.content, new CaseBuilder() .when(log.statusCode.eq("0") .then(sucessCount+1) .otherwise(successCount), client.id ) .from(log) .leftJoin(client) .on(client.name.eq(log.name)) //이 group by가 문제 .groupBy(log.name, log.content, client.id); queryFactory.insert(stats) .columns( stats.name, stats.content, stats.successCount, stats.clientId ) .select(subQuery) .execute();

안녕하세요 맛비님. 23:42 초에 보시면, PL의 clock을 90 MHz로 맞춰주셨습니다. 그리고 Input Frequency가 33.33 MHz로 되어있는데, PS 즉 Arm processor의 동작주파수가 33.33MHz인가요? Arm processor의 zynq 내 정해져있는 건가요? 바꿀 수 있는 방법이 있는지 궁금합니다. 감사합니다.!!

선생님 안녕하세요. 항상 좋은 강의 잘 듣고 있습니다. 두가지 질문이 있습니다. 선생님께서 18:21에 좋은 성능을 보여준 이유로 imagenet의 가중치를 사용해서라고 말씀 하셨는데, imagenet의 훈련된 가중치는 애초에 cat and dog와 완전히 다른(imagenet에 많은 강아지와 고양이 이미지가 있다고 하더라도) 데이터로 만들어진 결과인데, cat and dog 데이터 셋에 적용해도 높은 정확도가 나오는 이유가 궁금합니다. 그리고, 개인적으로 인도 새 25종을 분류하는 모델을 만들고 있는데 그렇다면 강의와 같이 imagenet의 가중치를 가져와서 훈련하는 것이 아무것도 없는? 가중치로 훈련하는 것보다 좋은 성능 만들어 낼까요?

안녕하세요 맛비님! Lab2 exam부분 진행하면서 simulation을 돌릴 때 simulation이 멈추는 문제가 계속 발생합니다.. 처음에는 cnn_kernel module이 가장 하위 module이라 이 module이 문제 없이 동작하게 설계하면 다른 module들도 비슷하게 하면 될 것 같아서 제가 따로 testbench 파일을 만들어서 동작을 확인해보려 했는데, input valid 신호가 들어오기 직전 부분에서 자꾸 simulation이 멈춰버립니다... 그래서 제가 구글링을 해봤는데 testbench 작성이 bad 해서 그럴 수 있다는 얘기 정도밖에 안나오네요...(testbench 작성은 지금까지 제공해주신 testbench 파일과 거의 비슷한 flow로 reset_n을 주고 i_in_valid 를 high로 주고 output관찰하려고 했던 단순한 testbench였습니다) 그래서 나머지 모듈도 모두 코딩을 하고 맛비님이 제공해주신 run.py 를 통해서 제대로 동작하는지 simulation 해보려고 했는데, 또 simulation이 멈춰버립니다.. 여기서 더 진행이 안됩니다.. waveform 옵션이 있어서 그런가 하고 그냥 waveform gui없이 돌려봐도 Start이후에 진행이 안됩니다... 강의 중에 3D이상의 array 선언을 하면 simulation time에 문제가 있어 vector 선언 후 Indexed part select를 통해 설계하셨다고 하셨는데, 저도 제공해 주신 frame안에서 그냥 TODO 부분만 Indexed part select를 통해서 코딩한 건데 왜 이런 문제가 발생하는지 잘 모르겠습니다. 제가 작성한 code에 문제가 있으면 simulation 결과를 보고 수정해서 정상적으로 동작하게 하고 싶은데 simulation이 완료가 안되니 어떻게 해야 할지 모르겠습니다... Matbi님의 lab2_solve 부분을 잠깐 확인을 했는데 크게 다르게 작성하지 않은 것 같은데 lab2_solve에서 run.py를 실행해보면 정상적으로 결과가 나옵니다. Verilog HDL이랑 FPGA강의를 수강해오면서 simulation이 멈춰서 디버깅을 못하는 경우는 없었는데 simulation이 멈춰버리니까 어떻게 디버깅을 해서 진행을 해야 할지 정말 모르겠습니다... 이럴 때는 어떻게 접근해야 하는지 여쭤보고 싶습니다. 긴 글 읽어주셔서 감사합니다!

안녕하세요 맛비님. AI HW 6장 강의를 들으면서 MAC연산량 관련하여 의문점이 생겨서 질문 드립니다. https://www.inflearn.com/questions/735204/%EC%95%88%EB%85%95%ED%95%98%EC%84%B8%EC%9A%94-%EC%B1%95%ED%84%B06-7%EC%97%90-%EB%8C%80%ED%95%9C-%EC%A7%88%EB%AC%B8%EC%9E%85%EB%8B%88%EB%8B%A4 (관련 질문글 링크) 1. 강의에서는 weight 수를 "kernel의 sample수"라고 하셨는데, 위 질문 답변의 A2에서 처럼 정확히는 Convolution layer에서의 weigth 수는 "kernel의 sample수 * Output channel 수"가 맞지 않나요? 즉, OCH :output channel수 * (ICH * Kx * Ky : Kerner의 sample 수) 2. Convolution layer에서의 MAC수를 계산할 때는 Kernel size * Input Channel * Output Channel 을 한 게 output feature map의 한 point(1*1*OCH size)에 필요한 연산수 이기 때문에 위 질문 답변에서의 A1.하나의 layer 에서의 MAC 량 = OCH* ICH * KX * KY이 아니라 Kernel size * Input Channel * Output Channel* Output Feature map Size를 하여 하나의 layer 에서의 MAC 량 = OCH * ICH * KX * KY * (Output Feature Map size) 를 해줘야 맞는게 아닌가 싶습니다. 3. AI HW 6장의 교안에 LeNet-5 Network구현에 필요한 MAC연산수가 341k라고 되어있는데, 첫 Conv layer에 필요한 MAC연산은 (2번이 맞다면) 5*5*1*6*28*28 = 117,600이고 두 번째 Conv layer에 필요한 MAC연산은 5*5*6*16*10*10 = 240,000으로 두 개의 Conv Layer에서의 MAC연산량만 해도 357.6k로 341k를 넘는데 Fully Connected Layer에서의 MAC연산량을 더하면 더 커질 것이라 생각하는데 MAC연산량이 341k가 맞나요?? 정확한 값을 알고 싶습니다. 117.6k+240k+20*84+84*10 = 368.52k가 맞나요? 구글링해도 MAC수에 대한 자료는 잘 안나와서요.. 3-1. Fully Connected Layer가 2개라고 하시고 C5-F6에 하나, F6-OUTPUT에 하나 해서 두 개라고 하셨는데, 검색을 해보니 F6-OUTPUT은 Gaussian connected layer라고 fully connected layer가 아니라고 하는데, 뭐가 맞는건지 잘 모르겠습니다.. S4-C5/ C5-F6가 두 개의 FC layer인건가요? 4. HW engineer라면 연산량을 잘 파악할 수 있어야 된다고 하셨기에, Network Model을 보고 Weight와 MAC연산수를 잘 파악할 수 있어야 될 것 같다고 생각해서 정리를 해보았는데 FC Layer에서의 Weight = Edge의 개수 = Input Node * Output Node FC Layer에서의 MAC = Weight와 동일 Conv Layer에서의 Weight = "kernel의 sample수 * Output channel 수" = OCH *ICH * Ky * Kx Conv Layer에서의 MAC = (Output Feature Map 의 Size) * Weight 수 = (Output Feature Map 의 Size) * OCH * ICH * Ky* Kx 라고 생각했는데, 옳게 파악한 것이 맞을까요? 항상 강의 잘 듣고있습니다. 바쁘신데도 질문에 친절하게 답변해주셔서 감사합니다 맛비님! 긴 글 읽어주셔서 감사하고 좋은 하루 되세요 :)
