Build Neural Network With Ms Excel -

For example, cell E2 (w₁₁) becomes: =E2 - $α$1 * E6 where α is in cell A1 (e.g., 0.5).

Assume row 2 (x₁=0, x₂=0):

| Weight name | Excel cell | Initial value | |-------------|------------|---------------| | w₁₁ (x₁→h₁) | E2 | 0.3 | | w₁₂ (x₁→h₂) | E3 | -0.2 | | w₂₁ (x₂→h₁) | F2 | 0.5 | | w₂₂ (x₂→h₂) | F3 | -0.1 | | b₁ (bias h₁) | G2 | 0.0 | | b₂ (bias h₂) | G3 | 0.0 | | v₁ (h₁→out) | H2 | 0.4 | | v₂ (h₂→out) | H3 | 0.2 | | b_out | H4 | 0.0 | For each training sample (row 2 to 5), copy these formulas across rows .

Example for w₁₁ (E6): =SUM($A$2:$A$5 * R2:R5) (use Ctrl+Shift+Enter as array formula or SUMPRODUCT) For example, cell E2 (w₁₁) becomes: =E2 -
