Apa perbedaan antara regresi linier 'reguler' dan regresi linier deep learning?

12

Saya ingin tahu perbedaan antara regresi linier dalam analisis pembelajaran mesin reguler dan regresi linier dalam pengaturan "pembelajaran dalam". Algoritma apa yang digunakan untuk regresi linier dalam pengaturan pembelajaran yang mendalam.

Dengan asumsi bahwa dengan mempelajari dalam-dalam, Anda maksudkan jaringan syaraf yang lebih tepat: vanilla yang terhubung sepenuhnya dengan jaringan saraf maju dengan hanya fungsi aktivasi linier yang akan melakukan regresi linier, terlepas dari berapa banyak lapisan yang dimilikinya. Satu perbedaan adalah bahwa dengan jaringan saraf satu biasanya menggunakan gradient descent, sedangkan dengan regresi linier "normal" menggunakan persamaan normal jika memungkinkan (ketika jumlah fitur tidak terlalu besar).

Contoh jaringan neural feedforward yang terhubung penuh tanpa lapisan tersembunyi dan menggunakan fungsi aktivasi linier (yaitu fungsi aktivasi identitas):

masukkan deskripsi gambar di sini

Jika Anda mengganti fungsi aktivasi lapisan output dengan fungsi sigmoid, maka jaringan saraf melakukan regresi logistik. Jika Anda mengganti fungsi aktivasi lapisan output dengan fungsi softmax dan menambahkan beberapa unit output, maka jaringan saraf melakukan regresi logistik multikelas: Perbedaan antara regresi logistik dan jaringan saraf . Jika Anda mengganti fungsi biaya dengan kehilangan engsel , maka jaringan saraf adalah SVM dioptimalkan dalam bentuk primal: http://cs231n.github.io/linear-classify/ .


Berikut adalah contoh yang ditunjukkan pada gambar di atas yang diprogram dalam TensorFlow:

Terima kasih banyak atas jawaban terperinci dan waktu yang Anda habiskan untuk menulis ini. Saya perlu waktu untuk mencerna ini, dan akan kembali kepada Anda dengan komentar / pertanyaan! Terima kasih lagi!

Menggabungkan jawaban Anda dan Sengiley dengan apa yang saya mengerti, dapat saya katakan - regresi dalam pembelajaran mendalam memiliki 1. 3+ jumlah lapisan tersembunyi; 2. Fungsi aktivasi adalah linier (atau fungsi Aktivasi Identitas); 3. Fungsi kerugian yang kami optimalkan adalah galat kuadrat dalam lapisan output. Terima kasih!

2

Untuk regresi, yang untuk pembelajaran mendalam adalah nonlinier dalam kebanyakan kasus, lapisan akhir memiliki 1 neuron dengan fungsi identitas dan fungsi kerugian yang kami optimalkan adalah MSE, MAE daripada biner atau lintas-entropi kategoris yang digunakan untuk klasifikasi.

Hai, terima kasih! Saya harap saya tidak meminta terlalu banyak, tetapi bisakah Anda mengarahkan saya ke implementasi kertas / algoritma? Saya mencoba mencari, tetapi sebagian besar saya menemukan hal-hal yang berkaitan dengan regresi logistik :(
